Economics of Terrorism

On 22nd, 23rd, and 24th February, Alan Krueger, known to economists as a leading labour economist coming up with innovative (and sometimes controversial) empirical research strategies or known to the general public as a New York Times columnist (the list of his columns), came to LSE and gave this year's Lionel Robbins Memorial Lectures. The topic was - lo and behold - terrorism.

Professor Krueger began his lecture by explaining why economics can investigate terrorism. His answer: it's an application of occupational choice theory. :)

The recurring theme of the three-day lecture series was that poverty DOES NOT matter to terrorism. After the 9/11, the world's political figures all say that one of the important strategies to combat international terrorism is to tackle poverty. But there is NO evidence for supporting such a claim.

The first lecture focuses on micro evidence for causes of terrorism. First, public opinion polls conducted in Islamic countries suggest that poor people are just as likely to justify terrorism as rich people are. If anything, MORE educated people tend to support terrorist acts. Surveys of actual terrorists reveal that they are richer and more educated than the general public, except for the IRA in which terrorists were poor and uneducated. Prof. Krueger provides possible explanations for this anomaly: for Northern Ireland, rich people could leave for the United States easily. Also the Northern Ireland case is more like a civil war, for which recent economic analysis shows that poverty matters.

A possible theoretical explanation for why richer and more educated people become terrorists is as follows. From the supply side, well-off people are drawn to extreme views because information acquisition cost is low. Poor people are unable to learn anything. From the demand side, a terrorist group wants to recruit smart people because it requires high-skilled labour to conduct terrorism and the cost of failure is substantial (if members are arrested, the group as a whole will not survive).

It's not that lack of education matters. It is the content of education that matters.

The second lecture focuses on macro evidence for causes of terrorism. Using the US government data (the reliability of which, though, is severely limited as pointed out in this New York Times column in 2004), the countries of origin of international terrorism are by no means poor while the countries of target tend to be rich. What's correlated with countries of origin is the lack of civil liberty. Investigating nationalities of foreign insurgents in Iraq captured during April to October 2005 yields similar results. They are not coming from poor countries but from countries without civil rights.

The last lecture then focuses on consequences of terrorism. There are two views on economic consequences of terrorism: terrorism having a large effect versus terrorism having a small effect. Evidence seems to suggest that terrorism has a significant impact on the economy if it is repeated for a long period while it has a negligible effect if it is temporary. Abadie and Gardeazabal (2003) convincingly show that terrorism in the Basque region of Spain reduced the region's GDP by 10 percent. Another study (I forgot the author's name - if you know this study, let me know), on the other hand, shows that terrorist attacks against listed companies in the U.S. during 1975 to 2002 (excluding the 9/11 as an attack against airline companies) reduced the stock values of targeted companies just by 0.064 percent of the US GDP per year.

I couldn't follow the lecture part on psychological consequence of terrorism...

If you're interested, here's the list of papers on which the lectures were based upon (on Prof. Krueger's website).

Life Expectancy

Lent term is about to end. I learned several things during this term. But I'm sure I'm going to forget them in a month or so. So let me write them down here. The first instalment is about life expectancy. If you spot any inaccurate descriptions below, let me know by leaving a comment.

1. Life expectancy is visualized as follows. Take age on the x-axis and take the proportion of survivors to a certain age on the y-axis. From the data on death rates for each age cohort, you can plot the proportion of survivors for each age. The area surrounded by the x and y axes and the plot curve is life expectancy at birth. (Added on 16th March: Of course, one cannot estimate life expectancy for each cohort because then you need to track this cohort until the last person dies. For practicality, demographers assume that each cohort will face the same survival probability as the one currently faced by older cohorts. Special thanks to Bessho-san (his Japanese blog), who emailed me on this point.)

2. In the demography literature, various ways to decompose change in life expectancy between two points in time have been developed during the past 25 years. But the most useful is still one of the first proposals: Arriaga, E.E. (1984). "Measuring and explaining the change in life expectancies", Demography, 21, pp.83-96.

3. Crude death rates are sensitive to age composition of the population. Even if the death rates for every age group doesn't change, the crude death rate of the population goes up if the proportion of old people to the population goes up. A solution to this is standardized death rates, in which the population death rate is calculated with the age structure fixed. But then the arbitrariness of the choice of a "standard" age composition is a problem.

4. A good reference of these issues is Demography: Measuring and Modeling Population Processes, by Samuel H. Preston, Patrick Heuveline, and Michel Guillot (Blackwell Publishing, 2001).

Drum & bass meets live drums

This week BBC 1Xtra, a digital radio station specializing in urban music, features XTRABASS06 - everyday at midnight it broadcasts drum & bass club nights live for two hours. The first 1 hour of last night's show was awesome. L Double, a drum & bass DJ who has a regular show on 1Xtra, plays his dj set with Jungle Drummer, probably the world's only drummer playing drum & bass. Drum & bass is a digital music - all sound is created by computers. But when it meets live drum sound, voila, the vibe is totally different. Check this out! (Skip the first few minutes and ignore the last 50 minutes or so where Scratch Perverts play their lost-in-focus mediocre DJ set)

By the way, I went to Paris last week for just two days. Below you can see photos and so forth.

Centre Pompidou, the back facade

Centre Pompidou, the back facade
Designed by Renzo Piano and Richard Rogers in 1977. Paris's counterpart of Tate Modern. But it doesn't just house a contemporary art museum but also a library, performance spaces, and a cinema - a revolutionary concept for an modern art museum. To ensure a vast space inside, air-conditiong, pipes, lifts, and escalators are all attached outside the building. As is often the case with contemporary art museums, the building itself is more fascinating than what it houses inside. Its top-floor cafe/restaurant Georges is superb in terms of its decor and foods except for the fact that the waiter sneaked a bottle of Vittel into my bill, which raised the total amount by 6 euro.

Tour Eiffel

Tour Eiffel
Again this is what every tourist takes a photo of. But I had to. Viewed from the hill of Palais de Chaillot (just a few second walk from Trocadero metro station), the Eiffel Tower, combined with greenery of Parc du Champ de Mars at the back and Palais de Chaillot in the front, taught me the pleasure of watching a geometrically symmetric construction. Some youngsters were playing skateboards and inline skates on the vast square of Palais de Chaillot with a fantastic view of the Eiffel Tower, probably the world's most luxurious place for skateboarding and inline-skating.

Parc Monceau

Parc Monceau
Normal tourists wouldn't visit this park in the 8th arrondissement. But when I browsed through Chikyu-no-Arukikata Paris (the Japanese counterpart of Lonely Planet with far more photos and far less sentences), a photo of Parc Monceau caught my eyes: a pond surrounded by a Corinthian colonnade. It is a tranquil, but strange park: weird follies are scattered around the park.

Colette

In addition to being caught up in a metro train carriage just like in London, I was also caught up in rain just like in London. Even worse, rain in Paris never stops, unlike London. I forgot bringing an umbrella. I tried to run away into the Louvre, only to find that Tuesday is a holiday for this massive museum. I looked into Time Out Guide Paris and found Paris has got what they call "concept stores", represented by Colette. Thankfully, the Colette store is close to the Louvre.

It's an interesting store. They sell anything as long as it's cool - from iPod accessories to fashionable digital cameras, from cool music CDs to art books on the ground floor. Upstairs they have trendy clothes on sale - I found a very fancy jacket for a man (but with the price tag of 800 euro) - as well as some art exhibition featuring UK (The Evening Standard's news headline posters at newsstands fill up the entire wall... What can be art changes a lot across the Channel).

Here I found an interesting art magazine: ArtIt. This is a Japanese art magazine written both in Japanese and in English. This is what I've been looking for. Japanese words and expressions used to talk about art are often very difficult to translate into English. This magazine tries to overcome this. Even though this is nothing to do with Paris, I had to buy this magazine.

While strolling around Paris, I found quite a few small shops selling and displaying Japanese stuff. Japanese restaurants also abound. I saw an ad poster of a manga school. I felt the fact that Japan is cool is already obvious in Paris. Parisians seem to now try to take it to a next level by treating Japan as one of many cool things they can exploit. In this sense, Paris goes ahead of London.

Paris Metro

Compared to London Underground, Paris metro is much, much more pleasant to use. Although I was stuck in a Ligna 1 train carriage not moving for 15 mintues - I think I was very unfortunate; why on earth did I need to go through this typical London experience even in Paris? - the design of train carriages and stations looked better. Paris metro trains do not decorate too much. Inside the carriage everything is basically silver. Outside the carriage they use pale colors to decorate. London Underground trains are painted in vivid colors like red and blue outside and for grab bars inside, which sometimes causes me a headache. Station platforms are clean and well-designed - some of which I even took a photo of. The space inside carriages is wider, the noise kept to a minimum. It's much closer to Tokyo's subway, but even better because Paris metro keeps advertisement to a minimum while Tokyo's is extensively decorated with ad posters.

Cathedrale Notre-Dame de Paris, the east side

Cathedrale Notre-Dame de Paris, the east side
I personally like the east side most. I didn't plan to visit the Notre-Dame Cathedral. But when I saw this east side from a distance when I walked on the bridge over the Seine (Pont de la Tournelle, the bridge between the Ile St-Louis and Latin Quarter), I immediately changed my mind.

Cathedrale Notre-Dame de Paris, the north side

Cathedrale Notre-Dame de Paris, the north side

Cathedrale Notre-Dame de Paris, the west front

Cathedrale Notre-Dame de Paris, the west front
I admit I did a bad job here. I tried to take a bit different photograph because the west front of the Notre-Dame Cathedral is what every tourist takes photo of. But what's beautiful about this side of the Cathedral is its symmetric facade. Taking its photo at an angle is a terrible idea...

Cathedrale Notre-Dame de Paris, the south side

Le Petit Marche

9 rue de Bearn - 75003 (Tel. 01 42 72 06 67)

A restaurant just two blocks north of Place des Vosges in Le Marais. With less than 20 euro, you'll have a fantastic lunch set - proper French with a hint of Southeast Asian flavour. Presentation is also artistic. If only I could speak French... (No waiter/waitress speaks English here and no English menu.)

Institut du Monde Arabe

Institut du Monde Arabe
Designed by Jean Nouvel in the 1980s. Windows are decorated with camera apertures, looking like an Islamic art pattern. If you go up to the top floor, you can see these windows from inside:
A window viewed from inside Institut de Monde Arabe
The top floor has a conference room with these windows on one side. I want to organize a conference here: it's cool.
A conference room in Institut de Monde Arabe

La Grande Arche de La Defense

La Grande Arche de La Defense
Designed by Johan Otto von Spreckelsen in 1989. Every bit of the gigantic Grande Arche shows no sign of compromise. What's particularly twisted is the fact that although the Grande Arche is located on the same straight line stretching from the Louvre Museum through Champs Elysees Avenue and the Arc de Triomphe, the Arche itself is facing slightly askew. In the picture above, the line of darker tiles goes straight to the Arc de Triomphe. Notice that the Arche is slightly looking left.

Who's an "engineer" in the economic policy sphere?

Today's EOPP Happy Hour was really enlightening. (For those who do not know what EOPP is, EOPP is a research group consisting of professors and PhD students of economics at LSE interested (mainly) in development economics and political economy.)

The topic was "What defines economics?" But the discussion flew into the issue of the relationship of economics with policy-makers.

We had Professor Paul Gertler from UC Berkeley as a guest. And he made a couple of revealing remarks.

In addition to academic works, he's been doing policy advice works in developing countries like Mexico, Argentina, Uganda, Kenya, etc. When he talked to politicians in these countries about what development policy should be undertaken, their first response was

"Does it get me into trouble?"

When he said no, then the next response was

"Does it make me look smart?"

When he said yes, then the third response was

"Does it make the public better off?"

He also told us that the reason for why conditional cash transfer schemes (CCTs) like Oportunidades (formerly known as PROGRESA) in Mexico and Bolsa Familia in Brazil, where poor households receive cash from the goverment conditional upon sending kids to school etc., is more acceptable for policy-makers than, say, simply providing education to all kids for free. The empirical evidence shows that CCTs are by no means more cost-efficient. But politicians love it because parents will vote for them if they implement CCTs (parents get cash!). Providing free education, on the other hand, does not directly benefit those with voting rights.

Then the following discussion led us to the idea that there needs to be "engineers" in the economic policy sphere, a metaphor suggested by Tan. Engineers are those who know natural science and apply it to real situations. Likewise, we need someone who knows economics and knows how to implement it to reality.

The following is the point made by Professor Mark Schankerman. Economists are good at finding WHAT the efficient outcome is. A good example is free trade. But economists are bad at finding HOW the efficient outcome can be achieved. That's why politicians often don't like the free trade policy, for example. In the process of implementing free trade, there will be those who lose from free trade. Politicans cannot ignore such people. Finding what the efficient policy is is like what scientists do in natural science. But finding how it is achieved in reality is a different job. In the case of natural science, engineers undertake such a job. What about social science?

Who can be an "engineer" in the economic policy sphere? Time was over at this point. I wonder if this is a journalist who understands economics well. Or maybe this is what political economists or political scientists (the distinction is very blurred these days) are all about.

This is how Japan does diplomacy.

Captain Tsubasa is one of the most well-known Japanese anime/manga in the world. I still remember a Chinese guy I met in London loves this cartoon. I still remember a French girl working at a travel agency in London who wants to travel to Japan because she wants to see the Japanese landscape illustrated in Captain Tsubasa. (I later learned that Captain Tsubasa was a big hit in France a few years ago, which triggers Europeans' interest in Japanese manga and animation.) I still remember a soccer shop in Allepo, the second largest city in Syria, decorates its entrance with posters of Captain Tsubasa (known as Captain Majid in the Middle East).

Now it's going to be used as a tool of developing friendship between Japan and Iraq (see United Press International; Middle East Online). But I wonder if the fact that Captain Majid will be aired in "The U.S. government-funded Iraqi Media Network" stifles everything...

Robotic floor cleaners

Everybody believes that Japan is always at the cutting edge, especially when it comes to consumer electronics products.

Not really true. I'm surprised to find iRobot Roomba. This fancy robot, developed by iRobot three years ago, automatically clean floors, something Japanese household appliance makers couldn't think of.

According to a discussion board on robotic floor cleaners for Japanese people, Roomba is on sale in Japan for 80,000 Japanese yen (near 800 US dollars or 400 British pounds) while you can buy one in the U.S. for 250 US dollars.

Part of the reason is likely to be the fact that Japanese people live in small houses, not enough space for a robotic cleaner to running around the floor. Toshiba produced something similar, but it's now discontinued...

This year iRobot even produces Scooba, which washes, scrubs, and dries the kitchen floor automatically! (See BBC News report.) I want to buy this... (It's not yet to be sold in UK.)

Anyway, that's a distant dream. All I need to do now is to find the best hoover in UK. Do you have any suggestions? Is Henry, the British original hoover, really good? (I found a Japanese website devoted to Henry and his family, which is far more informative than any English webpages on Henry... (Look at the official website of Numatic, the British company making Henry. The company doesn't seem to realize Henry's potential appeal to a wide range of consumers.)

The Virtue of Economics

Here's why I love economics.

During the last month, I was trying to explain the difference in agricultural policies between East Asian and Sub-Sahara African dictators: East Asians have promoted agricultural growth while Africans have screwed it up. We have seen this difference despite their similarities in terms of per capita income in the early 1960s, the political trajectory until the early 1990s (both regions were ruled by more or less non-democratic governments), and the motivation to promote industrial development on the part of the government.

My intuitive reasoning was this: a non-democratic government faces a trade-off between maximizing tax revenues and preventing citizens from undertaking insurgencies. Taxing both agricultural and non-agricultural sectors in a similar fashion allows the government to collect as large tax revenues as possible. On the other hand, this leads to citizens in the agricultural sector identifying themselves with those in the non-agricultural sector, and vice versa, in their relationship with the government. Therefore, citizens as a whole have a high incentive to threaten the government with insurgencies in order to demand less taxes.

Taxing two sectors in a different way, on the other hand, certainly reduces the amount of tax revenues but reduces the insurgency incentives for citizens as well. This is because citizens in the less heavily taxed sector do not identify themselves with those in the more heavily taxed sector, and therefore do not cooperate with them if heavily taxed citizens decide to take up arms against the government. This makes an insurgency more costly for the heavily taxed citizens. If the government follows this strategy, it wants to tax agriculture more heavily because taxable incomes are larger in the agricultural sector, at least, in the early stage of economic development (as was the case in the early 1960s for both East Asia and Sub-Sahara Africa).

The differential taxation is more desirable for the government if the loss of tax revenues due to this tax strategy is small. This is the case if there is a huge difference in taxable incomes between the two sectors. In many African countries, agriculture provides far more taxable incomes than non-agriculture as soil and climate conditions allow them to produce export cash crops such as cocoa and coffee. This leads to African dictators severely taxing agriculture while favouring industries. In East Asia, however, agriculture does not yield particularly high incomes relative to the other sector in the economy. This makes East Asian dictators to treat both agriculture and non-agriculture in a similar way (ie. promoting productivity growth by not destroying production incentives due to heavy taxation).

That was my speculation. Based on this idea, I worked on building a model showing this logic in a mathematically rigorous way. It turned out, however, that the above reasoning had a flaw in it. A mathematical model allowed me to realize that if agriculture is far more profitable than non-agriculture, then citizens in the non-agricultural sector are never willing to oust the government even if they are taxed as heavily as those in agriculture. This is because their gain from toppling the government (the amount of incomes taxed away) is small (their taxable income is small by assumption) while the cost of insurgency is independent of the size of taxable incomes. In this situation, therefore, only citizens in the agricultural sector have an incentive for insurgencies. Removing the tax burdens on non-agricultural citizens does not weaken insurgency incentives for agricultural citizens (they need to oust the government on their own anyway), only to reduce the amount of tax revenues. Therefore, the government never chooses the differential taxation as its optimal policy.

I couldn't have noticed this logical flaw if I hadn't tried to build a mathematical model. Your intuition can tell a lie while mathematics never does. This is why I love the way economists engage in theoretical analysis.

This love affair does not mean that I make progress in my research, though.

Baron 'At The Drive In' (Breakbeat Kaos)

Listen to this week's drum & bass chart no.1 tune!

If you like trippy house/trance music, you're gonna like it. What a beautiful track.

The producer of this track, Baron, emerged in the drum & bass scene last year. No one in the mainstream music scene notices this, but drum & bass has been constantly pumping out new amazing talents during the past few years. You may remember the names like Roni Size, LTJ Bukem, Goldie, Adam F, DJ Hype, DJ Zinc. But they are not in the centre of the scene anymore. Instead of pumping out uncreative tracks only taking advantage of their celebrity status, these old names are now busy discovering new talents. Drum & bass music scene is very healthy in this sense right now, unlike some pop music scenes.

Japan's succession "crisis"

If you are a Japan watcher, you know this issue in Japan: whether the Imperial Household Law (the law on the Japanese royal family) needs to be reformed so that a woman can ascend throne. (See this BBC article last month and this month.)

But BBC doesn't seem to understand the fundamental issue here (nor the Japanese media, though). The issue is not whether or not a woman can succeed to the throne but whether or not a child of a woman in the royal family can become the Emperor of Japan.

In its history of more than 1500 years, the Japanese royal family did have female emperors (there are eight of them, two of whom became the empress twice). The current law prohibiting a woman to succeed is a product of Meiji Japan (in the late 19th century). But no children of these female tennou (the Japanese term for the Emperor of Japan) ascended throne. Which means that the current emperor has blood inherited only through men during the past 1500 years.

Those Japanese putting heavy weight on tradition, therefore, oppose the idea that a woman becomes the Emperor of Japan. Don't misunderstand them as anachronistic sexists.

But does tradition matter that much? They even propose that "former members of the old aristocracy who left the Imperial Family after Japan's defeat in World War II could possibly be brought back." (quoted from BBC article.) This is nonsense.

What's wrong with imperial blood transcended through women? Yes, it never occurred in the last 1500 years. But think about 1500 years later from now. The Japanese Emperor in the year of 3506 will have blood inherited from more than 3000 years ago, through both men and women. What's wrong with this?

Princess Masako, the wife of Crown Prince Naruhito, suffered from depression because she was implicitly accused of having no male children by those tradition fundamentalists in the Imperial Court. If women can pass the Imperial blood, this kind of absurd thing will never happen.

By the way, BBC seems really curious on this issue. Its website allows visitors to post their opinions. I burst into laughter quite hard when I read this:

I think this old-fashioned monarchy should be abolished, as it has no longer any connection with the realities of life in Japan.
Anna, Iran

Which also makes me feel like hearing what people around the world would say to this issue. Can you post your view coupled with your national background? That will be interesting.

Swerve

Went to the Swerve party at The End nightclub last night. This is a drum & bass party organized by Fabio, one of the leading drum & bass DJs since day one who also has a BBC Radio 1 programme. The theme of the party is smooth drum & bass, in other words, liquid funk.

It's always interesting to see how the guest DJ responds to this concept of the party. Even DJs known for their hard, dancefloor-smashing style play a bit different set than usual. This kind of tension - creative people faced by some constraints in what they can do - sometimes creates a marvelous thing. (If you think DJs are not creative, you're absolutely wrong.)

Tonight's guest DJ was Bailey. He began with a series of liquid funk tunes, which is not his usual style. But he still tore the floor down. As the previous warm-up DJ was terrible at mixining tunes, his skill was in stark contrast. It kept me, and all clubbers in the floor, dancing.

Then he moved on to noisy-but-cosy style (I make up this phrase) - fast beats with slow melody and bass line. I love this style of music. Now I was just standing listening deep into music. It washed my mind away.

It was already fantastic, but Bailey didn't stop there. In the last 20 minutes or so, he revealed his own style, almost leaving the audience behind. The style got harder and the rhythm got totaly unexpectable. Different, irregular rhythms cross over each other, creating a totaly wicked vibe. Yeah, that should have been what drum & bass was all about. Complicated, unexpected, but still danceable. The current drum & bass scene tends to forget this. I couldn't resist dancing madly. There were a few people who understood this, dancing hard to this style of music. That was an amazing moment.

Bailey was too good to appreciate Fabio taking over tonight. Usually, I feel somehow relieved when Fabio takes over at this party, because his set is what attracts me to this party. But tonight, Bailey was too wicked, making Fabio less impressive. So I left the venue before 3am, when the party would be over.

I love drum & bass. It's one of the few, very few things that completely please and satisfy me. It's an increasingly scary thought that I will leave London in a couple of year's time. It's very hard to find a decent drum & bass party outside London...

P.S. I deleted the previous post. Thanks a lot for your comments and encouragements, Mir and Ikem. I appreciate this. I feel pretty much fine now thanks to this drum & bass party. :)

Freedom of expression?

Buck-Tick is one of my favorite Japanese rock bands. In 1995, they released an album including a track called Rakuen (a Japanese term meaning Eden). This track features, as an interlude, the reversed version of a melody you hear in an Islamic country - the sound of reading the Koran.

Soon after the release of the album, an Islamic organization in Japan criticised it as a profane treatment of Allah and, in response, the record company recalled the original album CDs and re-released the album with an edited version of the track.

As Buck-Tick was not hugely popular at that time, this news was only reported in a very small column in newspapers. I wonder what would have happened if it had been an album released by a massively popular pop singer.

New District Line train carriage


District Line train carriages are the oldest and ugliest among all London Underground lines. Since last year, however, new train carriages have been introduced step by step. They have got fancy grab bars. I love this design.

Italian guys

I always envy Italian guys. When they see a good-looking girl, they shamelessly approach her and start talking to her until they understand she's not much into talking to them. I can't do this. The extent that I can't do this is increasing with the degree to which this girl is good-looking.

This good-looking-ness thing always bugs me. It's an undeniable truth that talking to a good-looking girl itself is enjoyable for men (and probably even for women) because she entertains you by her appearance, if not by the content of conversations. This often obscures an obvious fact that you want to talk to someone with whom you can strike an interesting chat; even if you don't really enjoy what you are talking to a good-looking girl, you still want to talk to her because she's good-looking.

This annoys me.

Bow Arts Lane


An alleyway next to Bow Arts Trust (183 Bow Road, E3, London)

A visit to Whitechapel Art Gallery

I needed a break in my mind that has almost always been preoccupied with economics recently. So I paid a visit to Whitechapel Art Gallery this evening as it is open late on Thursday. The Gallery, located in East London, is more or less on the way from the School to my home. So it's also convenient to visit on the way home.


The ground floor exhibition pretty much sucks. Even if a piece of modern art sucks, however, you can still enjoy it with a digital camera in hand. A photograph can be very powerful. You can throw away any unnecessary images out of the picture frame. What you see on the right is such a result. The title of this installation is "zero built a nest in my navel", by the way.

Upstairs, on the other hand, is quite intriguing, personally. It is an exhibition to introduce the works of British architect David Adjaye. I didn't know of him, but it turned out that I did know one of his buildings: Idea Store in Chrisp Market Street, which I believed was the world's coolest local library.

What's more, several more works undertaken by this architect are located in places more or less familiar to me: T-B A21 Olafur Eliasson Pavilion (follow this link and scroll down to see photos) was built in Venice (the link will take you to my photos), which I visited last year (but I missed the Pavilion); a residential building under construction on Fairfield Road, which is within a walking distance from my place in East London; Rivington Place in Shoreditch (again in East London), where I frequently walked around; and Idea Store Whitechapel (yet again in East London), built near a vast Sainsbury's supermarket store I visited a couple of times.

The exhibition explains how he designs such buildings by taking into account the area surrounding the building site and by being inspired by African craft designs, which was quite intriguing.

On the way home, I paid a visit to one of his buildings - Idea Store Whitechapel:

FT's book review on Acemoglu and Robinson (2005)

I just found FT magazine's book review on Acemoglu and Robinson (2005). (See 18th January 2005 for discussions on this book.) I was always wondering what the general public's response to their innovative theory of democratization would be. Tim Harford - the reviewer - gives a thumbs-up overall. I hope this theory will soon be taught by high-school world history teachers.

Lent Term 2006 Week 3

Monday (23rd):
1430-1600 Job market seminar by Alvaro Bustos from Princeton
The rest of afternoon - Fatigue from last week's work prevented me from thinking properly...

Tuesday (24th) through Thursday (26th):
Wrote a research memo in which I describe a theoretical model that I have in mind and its solutions and implications. As this process involves mathematics, you can't skip any single step in logic. This requires you to think real hard. So it took longer to finish and I got exhausted more than expected.

But this is why I love economics. This process often takes you somewhere you didn't expect. Which means you find a new thing. I mean, the conclusion derived from this process is often different from what you expected. If you just rely on verbal arguments, this won't happen. Which means you don't really make progress in expanding our knowledge on society. That's why economists hate most arguments without explicit mathematical modelling made by social scientists outside economics.

Friday (27th):
1300-1400 EOPP Work-in-progress Seminar
Afternoon - Wrote email to Professor Caselli, the speaker at today's seminar, on his presentation as what he's trying to do is quite similar to my research - I should talk to him soon. Then figured out how to use Excel2Latex for Ameet. The end result is written down here (look for "EXCEL2LATEX").
1800-1900 EOPP Happy Hour

Saturday (28th):
Complied the dataset for my research. Although it's theoretical, to motivate my research, it's good to present the data showing what I'm trying to explain is in fact a reality. (I followed Tim's advice last week.)

Sunday (29th):
Started reading Esteban and Ray (2006) to hone my skill of writing a theoretical paper. Debraj Ray's papers are good for this purpose - they are theoretically rigorous but still carry a huge relevance to reality so I don't get bored. What struck me during this week (and during the Christmas holidays, when I worked on the same research idea) is the fact that I haven't been exposed enough to theory papers. (This is partly because both development economics and political economy these days tend to be empirical (for development economics, to the extent that Dilip Mookherjee - one of the leading theoretical development economists of the present days - expresses his concern that there is too little theory in the field) and because due to my research topic I've been forced to read tons of descriptive (ie. non-mathematical) papers in political science, which was more often than not agony.) That is why I took almost a week to write up even a sketch of a simple model, or so I thought.
Also started proof-reading the proofs of Tim's forthcoming book as part of research assistance work for Tim.

Lent Term 2006 Week 2

Here's an example of my daily life as an economics PhD student at LSE interested in development economics.

Monday (16th):
1300-1400 Development & Growth PhD Seminar
1430-1600 Job Market Seminar by Tavneet Suri from Yale
1700-1830 LSE/UCL Development & Growth Seminar by Eric Verhoogen from Columbia
The rest of the day - Read Esteban and Ray (2001) to figure out how larger groups can be more effective in conflict.

Tuesday (17th):
Late morning - Have a brief chat wih Tim on my own research and on our Health & Democracy project.
The rest of the day - Following Tim's advice, try to find data on agricultural tax rates in Africa and East Asia for my own research and get to know Anne Krueger et al. eds. The Political Economy of Agricultural Pricing Policy (John Hopkins University Press, 1991).

Wednesday (18th):
Morning - Following what Tim told me yesterday, run a few regressions for the health & democracy project (in vain).
1600-1730 LSE/UCL Development & Growth Seminar by Alwyn Young from Chicago
The rest of the day - Read Suri (2005) for the health & democracy project.

Thursday (19th):
Morning - An idea occurs to me and run a few regressions for the health & democracy project (in vain).
Lunchtime - Have power lunch with Sonia (by power lunch I mean a lunch over which conversations are all about each other's research)
Afternoon - Read Montalvo and Reynal-Querol (2005) for my own research. Try to find a way to get around an ad hoc assumption made in the theoretical model that I'm working on - and learn that the marginal cost of insurgency must be convex.

Friday (20th):
Morning - Try to find data on cross-country infrastructure data for my own research and remember Canning (1998).
Early afternoon - Have a chat with Maitreesh (my supervisor) on my research and receive a couple of modelling tips, told to write a short memo of the model and its analysis based on which we can talk further.
The rest of the afternoon - Work on the theoretical model for my own research and come up with an idea to implement Maitreesh's advice.
1800-1900 EOPP Happy Hour
The rest of the evening - Talk to Tianxi on where the accountability of the Chinese government comes from and then to Madhav on our potential new research project inspired by today's EOPP Happy Hour. After coming home, read Lemieux (1998) from which Suri (2005) seems to get inspiration.

Saturday (21st):
Continue reading Lemieux (1998). Then start writing a short memo of the model, following what Maitreesh told me yesterday.

Sunday (22nd):
Continue writing a short memo of the model.

Mackerel stewed with miso (saba no miso-ni)

It's time for lesser-known Japanese cuisine again!

Another whole mackerel was in the fridge today (I bought two yesterday). As one day has passed, eating it raw isn't a choice anymore. So I tried to cook it in a very Japanese way. It's called "saba no miso-ni" (mackerel stewed with miso). Here's a recipe:

1. Mix 400cc of water, 200cc of Japanese sake, one spoonful of sugar, one spoonful of soy sauce, and sliced ginger in a pan, and then bring it to a boil.

2. Place 130g of miso paste in a jar, add about 100cc of the "soup" made in Step 1 to it, and mix it with miso paste until the paste is dissolved into the soup. Keep this aside.

3. Add mackerel fillets to the soup made in Step 1. Place a lid onto the pan and heat gently for 5 minutes.

4. Open the lid and add half of the miso paste soup made in Step 2 to the pan. Then place the lid again and keep heating gently for another 5 minutes.

5. Open the lid and add the remaining miso paste soup and a hint of rice vinegar.

That's it! Miso paste is easy to get burned. That's why you shouldn't add miso from the beginning. A hint of rice vinegar in Step 5 makes the taste milder.

I've kept saying this since yesterday. But it was brilliant! I'm happy to be born as a Japanese. :)

Stewing fish in soup like the one made in Step 1 above is a very Japanese way of cooking fish. (The soup is not for drinking. It is just for stewing fish though we can serve stewed fish dipped in the soup.) We don't just eat raw fish as sushi.

Interestingly, I didn't like stewed fish when I was in Japan. More generally, I didn't like cooked seafood meals when I was in Japan. Since I started a life in London, I've begun missing fish. Then here I am, eager to explain a Japanese recipe for cooking fish!

Honestly speaking, this installation is just a bunch of white boxes piled up if you see it alone. But this art must be coupled with Tate Modern's Turbine Hall and viewed as a whole. This leads me to the above photograph, different from any other photos of this installation.

Neginuta

This blog sometimes becomes a Japanese cuisine guide. It's such time again.

After coming home from the Billingsgate fish market, where I bought two whole mackerel for 3.50 pounds, I pickled one of them as described on 21st August 2005. For lunch, I ate a half by dipping in soy sauce. It was gorgeous as always.

For dinner, I tried a new thing: neginuta. I didn't know this way of eating pickled mackerel. But it is brilliant. Here's the recipe:

1. Slice pickled mackerel and chop spring onions.
2. In a bowl, put three spoonfuls of miso paste, one and a half spoonful of rice vinegar, and a spoonful of sugar (you can change the amount to your taste as long as you keep the ratio, just like making cocktails).
3. Add sliced mackerel and chopped spring onions into the bowl, and marinate them all.

That's it! The sweet taste of miso and the sour taste of pickled mackerel along with the crunchy texture of raw spring onions melt together in your mouth, producing a pleasant sensation.

By googling Japanese websites, I found that neginuta refers to marinating spring onions (or, more precisely, negi (Japanese leeks) - but I prefer using spring onions as I doubt Western leeks fit this cuisine) in the miso/vinegar/sugar mixture. Some seafoods like boiled octopus or squid are sometimes added. Adding pickled mackerel is probably not a standard thing to do. Anyway, I'm probably the first person who introduces neginuta to English speakers as googling it in English doesn't yield any result. :)

Making Presentation Slides including Maths

I can sometimes become a computer geek. Here's proof.

Economics uses mathematics. Writing an academic paper in economics requires a word processor capable of inputing and outputing mathematical expressions. Microsoft Word is horrible for this purpose. So most economists use a word processor software called Scientific Workplace.

Still, Scientific Workplace is horrible. Its help files are hieroglyphics. I've already wasted tons of time to figure out how to do one thing or another with this software. But as long as writing a paper is concerned, it is not too bad.

When it comes to making slides for presentation, however, Scientific Workplace is even more horrible. Basically it's useless for making decent slides. Microsoft PowerPoint coupled with TexPoint doesn't work quite properly, either.

I figure out the ideal software environment for making slides for presentation in the economics profession (or any academic discipline using mathematics): MiKTex + TeXinicCenter + Prosper. (For Prosper, this page at University of Colorado is more useful than the official one.) They are all free to download and install.

In case you're interested, here's the recipe:
1. Download and install MiKTex.
2. Download and install TeXinicCenter.
3. Download and install Ghostscript (this is required to use Prosper).
4. Join TeXnicCenter-Users Yahoo! Group (this is necessary to download a batch file in the next step).
5. After your Yahoo! Group membership is accepted, download prospermake.zip by following the link provided in this message.
6. Unzip prospermake.zip and follow the instructions given in readme.txt to create a new output profile for TeXnicCenter.

One warning: do not install any software (MiKTeX, TeXnicCenter, or Ghostscript) under the directory of "C:\Program Files". The reason is this directory name includes a space, which prevents the new output profile from working properly (yes, this is Microsoft's fault). The simplest way to do this is install them all right under "C:" directory.

Now you're ready to use Prosper. You don't need to download and install Prosper itself; MiKTeX automatically does it when you compile a TeX file meant to use the Propser package. (You need an Internet connection, though.)

A couple of technical notes: Steps 3-6 are needed as TeXnicCenter is not compatible with Prosper by default. The main reason is that PDFLaTeX accompanied with TeXnicCenter doesn't work with Prosper. You need PS2PDF to create a PDF file. Ghostscript has this, and a batch file included in prospermake.zip allows you to use it properly.

Toshikoshi soba

I just had a New Year's Day soba noodles, a Japanese tradition.

Sorry I just lied. What's traditional in Japan is a New Year's Eve soba noodles (toshikoshi soba). I simply forgot eating soba noodles last night.

I bought chasoba noodles (noodles made of soba powder and green tea leaf powder) the other day in Oriental Delight supermarket, a newly opened East Asian food market in Chinatown. I boiled it for three minutes. British-managed or American-managed Japanese restaurants, notably Wagamama, don't seem to understand how long you should boil Japanese noodles to serve, by the way. They always boil it too long, serving jellyish noodles to disappoint Japanese customers. Italians know this. Their phrase "al dente" says it all.

While waiting, I sliced spring onions very thinly. In a very small bowl, I poured soba dipping sauce (made of soy sauce, mirin, and dashi soup (soup containing umami) and added the sliced spring onions.

Serve soba noodles boiled al dente, after washed with cold water, onto a large plate with a small amount of wasabi paste put on the edge. Pick up a few noodles with chopsticks and dip them into the dipping sauce. Add a hint of wasabi on top of it. Then quickly put them all into your mouth before wasabi melts into the dipping sauce. The al dente texture of soba noodles, the bitterness of raw spring onions, the umami taste of the dipping sauce, and the distinctively spicy taste of wasabi melt together in your mouth.

Lovely.

The moment I feel happy to be born as Japanese. After eating them all, have a cup of hot Japanese green tea. It clears the umami taste left in your mouth. This is how we Japanese do our thing.

Year 2005

The following is what I wrote before year 2006 arrived...

I hate this atmosphere of New Year's Eve. It forces everyone to look back at what happened this year and feel more or less sentimental about the year that's almost gone. I always try to defy this temptation. After having a Sainsbury's Indian curry and a vitamin tablet for supper (I don't feel like cooking tonight) and sitting at desk in my bedroom alone (my housemate is back at home in Scotland) on this quiet, cold evening in London, I give up.

The year of 2005 was certainly not the greatest in my life, but much, much better than the previous years in London. Speaking English is no longer a headache. In the past couple of months, even speaking academic things in English stops being a source of frustration.

A large part of the improvement in my life in London comes from two of my best friends - Alberto and Cheyok. Alberto (see his blog in English) is probably the one who understands me the most. Although he left London earlier this year, I visited his house in Italy last September. He's the guy I talked to for the longest time this year. Talking to him definitely made my life with English easier. Cheyok has always been incredibly nice to me. Without her permission, I think of her as my beautiful elder sister. :) From time to time we exchange email, talking about my private stuff, and meet up on several occasions. She's the one who always cheers me up.

The biggest event this year is nothing but a trip to Syria. (I will never be able to finish the Syria 2005 blog...) Thanks to Arabic-speaking Misao (see her essays on Syria in Japanese), I spent an enormously great time there - good food, nice people, total safety, and lots of historical sites. Honestly speaking, I partly sympathize the idea of Islam on women's outfits. During my stay there, I was relieved from being aroused by seeing scantily-clad girls. On the other hand, I realize Mohammed's aim (I believe he was too ashamed of his potential as a womanizer) is not perfectly achieved: a slender woman wearing a black burka still looks sexy. :) This trip certainly broadens my perspective on the world, something you never acquire if you just follow what America says.

Research-wise, this year has been extremely difficult. At the end of the three years as a PhD student, I couldn't finish writing up a single paper. But Tim has always been helpful. I started working for him as a research assistant last summer. One end result is his forthcoming book. (Chapter 2 "The Anatomy of Government Failure" is a must-read for everybody. Trust me.) I proof-read the whole manuscript and pointed out mistakes and made some suggestions. Beyond my expectation, he quite liked my work performance and, at the beginning of this month, offered co-authorship of a paper prepared for the American Economic Association Conference next month. This experience gave me kind of self-respect as a researcher, something that had kept deteriorating during the best part of this year. Now I came up with a new idea on my own research, working hard on it to make it to the presentation on 9th January.

Last but not least, I'm very lucky to meet Kotono, Alberto's girlfriend's friend. She's incredibly sweet and at the same time very assertive, a very rare combination for a girl. I like her a lot. Since I met her, my life has become much easier.

At the end of the day, it's people surrounding you who make you feel better. I couldn't learn this until I left Tokyo for London.

A hilarious paper

Debraj Ray's website (click "Miscellany" on the left column) took me to a hilarious (but quite serious) paper. If your surname is something like Zaitsu (a Japanese surname), you won't succeed as an economist as much as the person with the same background and the same ability and a surname like Akamatsu (another Japanese surname).

G Child's Refix

I supposedly have no time for updating this blog. But I've got to tell you this. I found a brilliant urban music DJ here in UK. His name is G Child.

Every Saturday night (from 10pm to midnight) his radio show on BBC 1Xtra, a DAB digital radio station in UK, features two sets of his 15-minute DJ mix called "the refix". This is not an ordinary DJ mix. G Child mixes vocals and beats from completely different sources. For example, last night, he mixed the vocals of Mary J. Blige - the queen of R&B - with various hiphop and dancehall reggae beats. In his second session last night, UK garage beats were mixed with US hiphop raps and vocals. This was absolutely HEAVY. It made sense a lot. UK garage artists often produce very innovative beats but they tend to be poor singers/rappers. US hiphop artists are much better skilled rappers/singers but the beats they make these days are so predictable and uninteresting. And G Child is very good at making a perfect combination from two different genres of music. I urge you to listen to last night's show online. The Mary J. Blige set begins after around 35 minutes while the UK garage vs US hiphop set starts at around 1 hour 40 minutes.

He needs to be known more widely. More generally, DJs tend to be underrated in public, often accused of their lack in creativity. That's absolute nonsense. True, there are many crappy DJs out there. But some are really making new music by mixing the existing tracks. Ever since I found this in London, probably the capital city of DJ culture, I've stopped buying CDs and begun recording DJ sets broadcast in radio shows instead. Artists can rarely make CD albums full of excellent tunes. CD singles are always coupled with rubbish tracks. Online music stores like iTunes and Napster only sell boring mainstream music while those selling tracks from independent labels online only sell tunes widely unknown because of its rubbish quality. Your music life will become much more interesting if you find good DJs mixing good tunes only in an unexpected way as G Child does.

(It's funny that mix CDs (CDs recording DJ sets) are almost always of poor quality. Maybe DJs lose their concentration when they are aware that their play is being recorded to preserve it in the CD forever.)

Zambia and the WTO for poor countries

I think this FT magazine article by Alan Beattie today is a well-written one on the reality of an African country's bureaucracy and economy, and of the World Trade Organization for poor countries.

Some interesting excerpts:

"God," Patel [- trade minister from the impoverished southern African state of Zambia -] says... "The FT has more capacity to do trade policy than we do."


Being a minister in a desperately poor country throws up unimaginable challenges. One of Patel's first jobs under Chiluba [the former Zambian president] was as minister of sport. On his second day in office, the entire Zambian national football team died in a plane crash in Gabon, an event that stunned the footballing world. "I had never even been to a bloody football match," he says. But he pushed and cajoled and eventually got the Danish government to agree to train Zambia's new team at the national football centre outside Copenhagen. "Then the next year we got to the finals of the African Cup."


In late June this year trade ministers from the LDCs [short for least developed countries] meet in Livingstone, Zambia ... There is a short debate about including commas around the expression "inter alia". Because of the francophone African countries present, the communique is translated into French and there is a discussion about whether the correct interpretation of "market access" is "acces sur le marche" or "acces au marche". ... The first day of the conference ends early because the interpreters are only paid to work until late afternoon. Finally, towards the end of the second day, Patel takes the conference chair himself and charges through the rest of the agenda in about half an hour, cajoling and demanding, flattering the delegates by calling them "brothers and sisters", and then bulldozing the communique into coherence. A Cambodian delegate, evidently impressed by this unusual display of executive decisiveness, suggests leaving all the negotiations to Patel. He reads out Patel's personal e-mail address to the conference and implores all present to send their ideas to him and let him decide. ... Later that night in the bar his frustration is evident. "We have no analysis, no data. That is why we spend our time changing commas and arguing about translations."


[Zambia's trade minister Patel] picks me up from the hotel five minutes early, waiting impatiently in the car while I get ready. "I caught you early, huh?" He drives himself to the office, railing against the lack of a Lusaka bypass when he is held up in traffic for two minutes.


The ministry has just moved to an impressive new tower block. The building was funded by an aid package from the Chinese government, which, Patel says, offered countries in southern Africa either a new party headquarters or a football stadium. "Most countries chose the stadium."


[A] more pressing matter this morning is the need to boot out the human resources people who have taken up residence in offices down the corridor, offices [Patel's] staff are supposed to move into.


[Patel] cites a computer simulation showing that EU demands for cuts in Zambian tariffs will lose the government $15m in precious tax revenue. But Zambia's ability to do such research is limited. It has access to an online computer model developed by the World Bank, which allows it to do simulations. "But I don't have the bandwidth, so I often get cut off," Patel says.


Often, he relies on briefing notes prepared by NGOs based in rich countries, such as Oxfam. "We get criticised for allowing NGOs to dictate our policy. But if we don't have the capacity to do our own research, what can we do?"


In October, in a drab, strip-lit room in the WTO's unglamorous Geneva headquarters, 21 officials from a variety of countries - Yemen, Afghanistan, Uganda, the tiny Pacific nation of Kiribati - sit in rows taking instruction on the agreements that underlie the organisation. Twice a year - once in English, once in French - the WTO offers three- week training courses to officials from LDCs. The class is taken by Claude Trolliet, an earnest shirt-sleeved WTO employee who has been with the organisation for 10 years. ... To me, Trolliet says: "Providing assistance to developing countries was not one of the functions of the WTO when it was set up. We have had to change ourselves."


This summer British Airways cancelled its weekly freight flight from Lusaka [- the capital city of Zambia -], citing the rising cost of airline fuel as global oil prices soared. Zambia's growers, left with tonnes of rotting produce, had to scrabble around to find space on other flights or truck their goods out through South Africa.


One afternoon Ronnie Parbhoo, an old schoolfriend of Patel's, shows me round his milk-packaging plant in Livingstone. Parbhoo is one of the few remaining members of Livingstone's formerly thriving business community - as in much of southern and east Africa, this is largely ethnic Indian. ... He once owned one of Livingstone's 40 factories in a flourishing textile industry. But output collapsed under east Asian competition, aided by president Chiluba's decision, egged on by the International Monetary Fund and World Bank, to slash protective tariffs rapidly in the early 1990s. So quick was the resulting implosion that most of the factory owners, disillusioned, left the country altogether. Of the 2,000 or so Indians formerly in Livingstone, about 150 are left. "The rest went to the US or Canada," Parbhoo says. "Or they are running corner shops in London." ... The industrial zone of Livingstone - now largely abandoned and overgrown, an African version of a midwestern American steel town - used to employ 10,000 workers. It now employs about 300, a third of whom work for Parbhoo.


Parbhoo sells his milk mainly to Zambians, limiting the size of his market. In theory, he could export his milk to Zimbabwe, but they don't have the hard currency to pay for it. Exporting it to Zambia's other southern African neighbours often runs foul of their hygiene rules - frequently used as a form of protectionism - and the country no longer has the government-backed testing facilities to make its own checks. It is, moreover, a long way across terrible roads to neighbouring countries, and the railway through Livingstone that crosses Zambia has been abandoned.

A hectic week

It's been a hectic week.

Last weekend I came to conclude that some kind of democratization does increase government consumption (see 19th October). If the dictator holds democratic elections without running for office himself, government consumption goes up. If the dictator runs for office, either winning or losing, government consumption does not change.

Last Monday I attended Torsten's lecture, realising one of his latest working papers deals with almost exactly the same question as the one I've been investigating - how democratization affects government consumption. His conclusion is that democratization followed by the parliamentary form of government increases government consumption while that follwoed by the presidential form of government does not.

Which is correct? The rest of Last Monday was spent on finding it out. The conclusion is Torsten is right and I'm wrong.

The next morning I talked to Torsten on this. He seems happy. :) But it seems to me that this is the result I was looking for. This government consumption project seems to reach its conclusion. So what should I do next?

On Thursday, I talked to Tim on this. When I started talking about my idea that turned out to be wrong, he showed his interest in whether or not the dictator runs for office. I used it as a right hand side variable (a variable explaining something else). He suggested to use it as a left hand side variable (a variable to be explained). Conversations flew and leadership survival in autocracy - when economic conditions make a difference in leadership turnover in autocracy - came out as a promising research topic. There is a huge literature on this in politicla science. But, as usual with political science, there has been no formal theory and their regressions always suffer from endogenous bias (ie. unable to tell the direction of causality). So there is room for an economist (ie. me) to investigate the issue.

Somehow, I saw some light. But the story didn't end here. (To be continued...)

A French dinner with Kotono at Victoire Pierre

It's been more than a month since I had dinner with Kotono last time.

Tonight we have a French dinner at Victoire Pierre, probably the one and only French restaurant in London that's affordable. It is a fantastic dinner. Especially what Kotono ordered is all big hits: mussels in tomato soup for a starter and duck with burgundy sauce for a main dish. My starter, foie grass, is excellent while my main dish, salmon fillets with cauliflowers in white sauce, is too peppery...

Kotono, a violinist, is going to compose several tracks and release an album from an independent record label next year. She says she wants to make music that's comfy but not cheesy. So I say, "Why not liquid funk, smooth drum & bass?"

Unexpectedly she shows her interest in this underground genre of music. I'm going to send her MP3 files of liquid funk to inspire her creativity. That's exciting!

Tips 4 Economists

Dim sum in style

Had dim sum lunch at Ping Pong with Cheyok and her friends.

I don't particularly like Chinese cuisine. But when it is served in style, I like it. Ping Pong, a dim sum restaurant in Soho, is hardly an ordinary Chinese restaurant. As the design of its official website suggests, its decor is like a cafe in a contemporary art museum. What impressed us was their jasmine tea. A tall glass with a ball-shaped dried jasmine leaf in it is served for each of us. A waiter pours hot water in it. Then the jasmine leaf ball begins budding, a jasmine flower emerging. It does taste proper jasmine tea. When you finish it, a waiter adds hot water again. I should have brought my camera to show this to this blog's readers...

If you like the way Chinese people eat foods, maybe this place is a bit too sophisticated and pretentious. But if you like Chinese foods but don't like the messy atmosphere typical of East Asia, this is your place to go.

There's another Chinese restaurant of this kind in Soho: Yauatcha (see 11th September 2004). Some say, according to Cheyok, that if Yauatcha is Prada in the comtemporary Chinese restaurant industry, Ping Pong is Miu Miu. I personally prefer Ping Pong.

Oh, the bill was 15 quid each. Not too bad at all, heh?

A "cabaret club"

A weird court ruling in Tokyo.

But I suppose non-Japanese people are puzzled at reading this news. What's a "cabaret club"? It's not a cabaret. My English dictionary says, "A cabaret is a restaurant or nightclub where live entertainment such as dancing, singing, or comedy is performed." No, if you go to a cabaret club in Japan, you won't see live entertainment.

This is a place for adult men to drink and have a chat with hostesses. That's the whole purpose of cabaret clubs. Some customers end up having intimate relationships with hostesses though cabaret clubs themselves are not part of Japan's infamous sex industry. (A distinction is a bit blurry, though.) It sometimes happens that a married man costs his family by falling in love with a cabaret club hostess. Smart businessmen or elite bureaucrats can be customers as well. Hostesses are therefore required to have a good skill to strike interesting conversations with such smart guys. Appearance is obviously an important factor to get loyal customers. In a way, the above court ruling is understandable.

If you are a man and work in a company or in a government office, your boss - who is almost always a man in Japan - often takes you to a cabaret club after working hours. As you might know, you can't reject such offers even if you have a girlfriend or wife. Going to cabaret clubs is not a shameful thing in front of your male collegues and friends. This kind of thing is part of the reasons I didn't try to get a job in Japan after finishing a college.

By the way, Japanese people call cabaret clubs kyabakura ("caba" plus "clu" - we like abbreviating a phrase this way). You almost never hear someone say "cabaret club" in full length.

The above description of cabaret clubs may be wrong as I haven't been to such places - I don't like drinking in the first place, plus I don't like such girls as working at cabaret clubs. If you are a Japanese man and spot a wrong description, post a comment anonymously.

I think the judges are frequent customers...

Mikami Chisako

Maybe I can sometimes introduce Japanese pop music to the reader of this blog.

Mikami Chisako (her offical website is unfortunately all in Japanese, but you can still enjoy photo gallery etc.) is definitely not a household name in Japan, but I think she represents a kind of Japanese-ness that Westerners increasingly appreciate these days. Soundwise, those who like British music probably like her music. Her music videos are art-house-ish, a bit underground, though. Check out her music videos (click links to play videos with your Windows Media Player):

Sou Tai Kei (meaning relative form - but "Sou Tai" can be read as "Aitai (I miss you)", which is endlessly repeated in the song)

3set

Fundamental (version 1)

Fundamental (version 2)

Viva la Revolucion

I still remember when I first saw her on television. I thought she was my ideal person. :) That's not true any more, but I still feel some kind of sympathy with her. Maybe I plainly like her skinny, fragile, and sensitive (but aggressive and dangerous at the same time) appearance mixed perfectly with her music.

A reflection on inefficient policies

(This is a preliminary draft. Comments are welcome.)

Why do governments in poor countries implement growth-retarding policies? Acemoglu (2005) discuss the following two mechanisms leading to inefficient policies: revenue extraction and factor price manipulation. (He suggests yet another mechanism, namely, political consolidation. But I personally don't buy this idea. So I put it aside here.)

Revenue extraction is a mechanism in which the government expropriates portions of profits earned by entrepreneurs. By taxing production, entrepreneurs' incentive to produce is discouraged, which also limits the scope of expropriation. Therefore, this mechanism does not completely discourage private production.

Factor price manipulation, on the other hand, is more deleterious. In this mechanism, the government distorts the allocation of factors of production by applying different de facto tax rates across production sectors. This creates rent earned by owners of production factors, which is extracted by the government. This is more harmful to the economy than revenue extraction for two reasons. First, if the government is not constrained at all, it prefers shutting down some industries completely in this case. In the case of revenue extraction, that would reduce tax revenues to zero, which the government does not want. Second, factor price manipulation hinders not only investment - as in the case of revenue extraction - but also the economy's overall productivity as well. A typical example of factor price manipulation is the regulation of entry of start-up firms.

Notice that while revenue extraction requires the government's capability of tax collection (including demanding bribe payments - if you don't pay me money, I'll shut down your business - and asset confiscation), factor price manipulation does not because the government can simply put up entry barriers to a certain sector. (This may not be true as the government still needs some means of enforcement in the case of factor price manipulation...)

Revenue extraction can be prevented if either of the following two conditions is satisfied.

1. The government is unable to collect taxes.

2. Separation of power along with checks and balances is set up. See Persson et al. (1997).

In terms of political development, it's the middle stage of development that is most susceptible to rent extraction.

Factor price manipulation can be prevented if either of the following two conditions is satisfied.

3. Factor price is inelastic. For example, Acemoglu (2005) shows that if the labour market is loose (supply of labor exceeds demand) in the absence of government policies, factor price manipulation is impossible as wages cannot be lowered further.

4. Political competition is stiff enough for the government's survival probability to be less than one and the electorate prefers no factor price manipulation. See Besley et al. (2005). Djankov et al. (2002)'s finding that limited and representative governments tend to have fewer entry regulations (after controlling for income) may or may not support this claim as they do not use a measure of political competition, which can be proxied by measures of limited and representative governments.

Condition 4 may not be sufficient to eradicate factor price manipulation. Krusell and Rios-Rull (1996) show that even a pure majority voting by citizens ends up preventing the adoption of new technology if managers with old technology outnumbers the rest of society. In reality, however, this is unlikely. The distribution of managers and workers in their model should be interpreted as de facto power (voting plus lobbying etc.) distribution.

For growth to be maximised, at least one of conditions 1 and 2 and at least one of conditions 3 and 4 have to be satisfied. Rich countries can be said to satisfy conditions 2 and 4. A very poor economy may be growing fast because condition 1 is met due to a poor government capability and because condition 3 is satisfied due to abundant labour.

It may be the case that East Asia follows a path from one situation in which conditions 1 and 3 are satisfied to another in which the government becomes capable of collecting taxes but labour market is still loose. As revenue extraction is less harmful than factor price manipulation, the failure of condition 1 only can sustain a reasonably high growth.

Africa, on the other hand, may follow a different path in which condition 3 fails before condition 1 does. This may be true given that African countries are generally not so densely populated. As a result, factor price manipulation completely retards growth, which sounds similar to what Bates (1981) describes (Robin Burgess's lecture note succinctly summarises this book).

Evidence seems to suggest that factor price manipulation matters more than revenue extraction to understand economic growth. Jones and Olken (2005) find that when economic growth accelerates, it is not because factor accumulation accelerates but because technological progress accelerates. As revenue extraction per se does not affect technological progress (it just discourages private investment, hence factor accumulation), it is when the government stops manipulating factor prices that economic growth takes off.

What is democracy?

(This post is a preliminary draft - comments are welcome. Last modified on 17th November 2005)

Political scientists and economists love to explore the relationship between democracy and socio-economic outcomes (Barro 1996, 1999; Przeworski et al. 2000; Bates et al. 2003; Glaeser and Shleifer 2005; Persson and Tabellini 2005). By democracy, however, we can mean different things. Unless we define democracy in a certain way, we are unable to develop a theory to understand the effect of democracy on, say, economic growth. It may be the case that some aspects of democracy are good for growth while others are not. Or, all aspects of democracy are complementary - a single aspect of democracy alone is not enough to ensure some outcomes; it works only if other aspects of democracy are also present.

Motivated by Levitsky and Way (2002)'s article on what they call "competitive authoritarianism", here I try to make a checklist for a country to be qualified as "democracy".

There are three stages to look at: (A) pre-election, (B) electoral process, and (C) post-election.

A: Pre-election

In the pre-election stage, the incumbent government lays the ground rule for competition for national political office (executive and legislature). A country is democratic at this stage if the following six criteria are met.

A1: Suffrage is universal - (nearly) all adults can vote.
A2: The executive is directly elected or indirectly elected by legislature.
A3: Elective legislature exists.
A4: Opposition parties are allowed to exist.
A5: No gerrymandering (ie. manipulating electoral rules and districts in favour of the ruling party) is undertaken.
A6: Press freedom is ensured.

Outright autocratic countries are disqualified at this stage - South Africa during apartheid did not satisfy A1 though it did satisfy A2-4. The military government seizing power by a coup is disqualified due to requirement A2, even if it satisfies A3 and A4 as is the case in Brazil during 1964-1985. The communist countries such as China and Cuba do not satisfy A4 while A2 and A3 may be satisfied - elections can take place without opposition such as Saddam Hussein, who claimed 100% voting share in an uncontested presidential election in 2002 (see a BBC article on it).

A1 is more subtle than it appears to be. In the United States South, black voters were de facto denied participation in elections by poll taxes and literacy tests until the 1960s. See Besley et al (2005).

Kenneth A. Bollen provides a dataset of suffrage across countries for 1950-2000. As long as you decide the threshold, you can tell whether or not A1 is satisfied in a country in a certain year with this dataset.

Acemoglu and Robinson (2005)'s theory of democratization mainly looks at A1 though the fact that in their model policies preferred by the median voter are adopted in a democracy implies that A2-A4 are implicitly taken into consideration. (If no opposition candidate is allowed to run for office, the single candidate can choose whatever policy he/she wants and gets elected.)

The minimalist way of defining democracy only looks at A2-4 (sometimes A1 as well). A good example is Przeworski et al. (2000)'s definition of democracy. As they are only concerned with the period after the Second World War, they ignore A1. But when you look back at pre-WWII periods, today's Western democracies initially didn't satisfy A1 by, for example, denying women their voting right. So Carles Boix, when he extends Przeworski (2000)'s dataset to the 19th and early 20th centuries, includes A1 as requirement for democracy.

The minimalist definition of democracy becomes problematic if you see countries such as Singapore, which satisfies A1-4 - it does satisfy A4: look at the list of political parties by Singapore-elections.com - but does not meet requirement A5 and A6. To avoid such complications, Przeworski et al (2000) come up with another requirement, which is to say power has to be alternated under the same electoral rule. This disqualifies Singapore as the same party has ruled the country ever since independence. This qualifying rule is quite successful to exclude "dodgy" democracies - Mexico and Senegal until 2000. But this is an outcome-oriented way of defining democracy. Theoretically, it's not clear whether, say, the Singaporean ruling party keeps power because of its undemocratic feature or because of its popularity among citizens. (Japan and Botswana are cases in point.) If you want to analyze the effect of democracy on political and economic outcomes, this is not appropriate to measure democracy. So I drop this requirement here.

A6 may not be appropriate either. Theoretically, press freedom is important to ensure that the incumbent's bad performance leads to electoral defeat - if voters do not know what the incumbents do, they may not want to vote them out. See Besley and Burgess (2002) and Besley and Prat (2005). So A6 is probably more appropriate to label as an institution complementing democracy, rather than a requirement for democracy. Freedom House's Press Freedom Survey provides yearly cross-country data on the degree of press freedom since 1980.

B: Electoral process

In the electoral process, the incumbents and opposition candidates compete for office given the conditions characterised by the above six aspects of pre-election. A country is called a democracy in this stage if it meets the following four criteria.

B1: Opposition candidates can freely run for office.
B2: Opposition candidates can freely conduct their electoral campaign.
B3: Voters can freely cast their ballots.
B4: Votes are neutrally counted.

Here what Levitsky and Way (2002) call competitive authoritarianism kicks in. It satisfies A1-A6 and B3-B4 more or less but it doesn't meet B1 and B2. B1 can be violated if the government arrests opposition politicians. B2 can be violated if the government denies opposition parties access to media.

B3 is related to the issue of secret balloting. Even in Western countries the secret ballots were introduced quite recently. See Baland and Robinson (2004).

B3 is also violated if voters are physically prevented from voting, as seen in Sri Lanka's 2005 election (in this case it's a rebel group, not the government, who prevented voters from voting, though).

The violation of B4 is what we call electoral fraud. The World Bank's Database of Political Institutions provides cross-country data (since 1975) on this (see variable FRAUD). Levitsky and Way (2002) point out that competitive authoritarianism often breaks down when it resorts to the violation of B4 - Marcos in the Phillipines and Milosevic in Serbia and Montenegro are cases in point. Ukraine's "Orange Revolution" can be included in this case though the incumbent himself didn't run.

C: Post-election

In the post-election stage, even the government elected in elections satisfying all the above conditions can become non-democratic if either of the following conditions is violated.

C1: The executive is checked and balanced by legislature and judiciary.
C2: Non-elective veto players do not intervene politics.

C1 is violated if a democratically elected president disbands legislature - such as Marcos in the Phillipines and Fujimori in Peru - or if the executive fires constitutional court judges after their ruling against the government. POLITY IV's "Executive Constraint" variable (named XCONST or EXCONST) measures this aspect of democracy, and according to North and Weingast (1989) - "Constitutions and Commitment: The Evolution of Institutions Governing Public Choice in 17th Century England," Journal of Economic History, vol.49, pp.803-32 - this is an important factor for secure property rights.

C2 is violated if the military or some religious authority intervenes politics. Examples of the former case are Thailand until the early 1990s and Turkey while Iran is a typical example of the latter.

An Application - Zimbabwe since 2000 -

With this list in hand, this article by The Economist magazine on Zimbabwe's parliamentary elections in 2005 is much easier to understand.

(Note that MDC is the main opposition party in Zimbabwe, and ZANU is the ruling party led by President Robert Mugabe.)

This country satisfies conditions A1-A4. A1 may not be satisfied as

"the 3m-odd Zimbabweans, most of them very likely MDC backers, who have been driven into exile by economic collapse or government repression, are barred from postal voting."
(But it wasn't until 2000 that Japanese citizens living abroad were allowed to vote, either.)

But Zimbabwe violates almost all other criteria.
"Since last time, constituency boundaries have been gerrymandered. A handful of MDC-held seats in populous urban areas have been abolished and new constituencies demarcated in rural areas where land-hungry peasants are friendlier to ZANU. Some urban seats have been merged with neighbouring rural ones, where voters are more pliable and ballot boxes in remote parts more easily stuffed."
This is a violation of A5.
Zimbabwe's most independent newspapers, notably the Daily News, remain closed, and ZANU virtually monopolises radio broadcasts.
This is a violation of A6.
Human Rights Watch, a New York-based group, reported less violence than before but said that intimidation and partisan laws give ZANU a huge advantage. It enumerates dozens of recent cases of MDC people being beaten, kidnapped and harassed by police and ZANU thugs.
B1 seems violated as well.
During the last general election, thugs and veterans of the independence war were paid to kill opposition campaigners... Now, because he wants to avoid shocking observers from South Africa (even though he is letting in only those he thinks most sympathetic), he is adopting subtler rigging techniques.
B2 was violated in the previous election but to a lesser degree in 2005 as
the MDC and Mr Tsvangirai are being given a few minutes of air time on the state television news (followed, of course, by an hour or so of Mr Mugabe and other ZANU leaders).


In the 2002 presidential election, B3 was violated:
Two years later, in 2002, the MDC's leader, Morgan Tsvangirai, a trade unionist, would surely have unseated Mr Mugabe in a presidential election, had the police not beaten up opposition voters, blocked people from reaching polling stations...
In 2005, the situation remains the same as
villagers are being told that ZANU agents will know, by looking through the transparent new boxes, who has voted for the MDC.
In the 2000 general election, B4 was violated:
The MDC lodged complaints about alleged vote-rigging in 37 constituencies which ZANU was adjudged to have won; but the courts, heavily influenced by the president and his friends, have failed in the past five years to deal with a single such case.
In 2005, the situation remains the same:
Of a sample group of 500 voters, barely half were listed correctly. Nearly a fifth of those named were dead; officials ensure that such "ghosts" are loyal ZANU voters.

Presentation postponed

My presentation, scheduled a week on Monday (14th), is postponed to the first week of next term. A job market candidate who was supposed to present next Monday takes my slot as another job market candidate also presents his work at the same time next Monday in a different PhD student seminar (the macroeconomics field), dividing LSE faculty members as the audience. For job market candidates, giving presentations at this time of the year is a practice for their job talks early next year. So it's good for them to have as many faculty members as possible in the audience and to have them provide critical comments. Since last year, the LSE faculty has got more serious on the placement of their job market candidates (that's my impression). So their presentations are given higher priority than mine.

Which is very lucky to me. I was still struggling to find what I could talk about a week on Monday. I repeatedly thought about cancelling the presentation. Now I can cancel it for a good reason. Hooray!

(If you don't know anything about "job market candidates", have a look at this guide, and you'll know what job hunting for economics PhD graduates is like.)

Chase and Status - 'Duppy Man'

The second instalment of the Let-Everyone-Listen-At-Least-Once-To-Drum-and-Bass campaign. :)

One reason for why the majority of people don't listen to drum & bass is its instrumental nature. Most drum & bass tracks feature no vocals. The majority do not like music without someone singing.

Things seem to begin changing in the drum & bass scene these days. More and more vocal tunes are produced - a good example is Shy FX and T-Power's 'Feelings'. Pendulum, an Australian trio emerging in the drum & bass scene during the past couple of years, put out 'Tarantula', which broke into top 50 of the UK Official Chart a few months ago.

Now you have this: Chase & Status 'Duppy Man' (listen to a sample). This track is a good example of how drum & bass meets dancehall reggae. It hits the top spot in BBC 1Xtra drum & bass chart this week. Listen, then you'll decide whether you like it or not. Do not hate it without listening to it.
