Thinking Strategically

As I was mentioning a couple of weeks back, I have been reading Thinking Strategically by Avinash Dixitt and Barry Nalebuff. This is a pretty old book, being first published in 1991 and the version I was reading is the 1993 paperback re-issue – there was no more revisits to this book by the authors since then but it’s been in print until now. I believe it’s largely used as readings for undergraduate economics students as well as students of business or management schools.

The 2 authors are great teachers of Game Theory in Princeton and Yale and have often adapted the principles this somewhat mathematical subject to the less mathematical real world. Thinking Strategically is a great attempt at discussing strategic thinking that follows from game theoretical analysis for the layman.

The good thing about ideas on strategic thinking is that their principles hold even when the examples they are attached to often become obsolete or arcane – that is not to say that Thinking Strategically features arcane examples. Most of the examples used to bring ideas across in the book are simple, often bordering trivia but they illustrate the essence of the concepts and can be used to explain the principles for similar but more complex issues. One of the case studies brought up that I particularly love is the one about a three-way duel where we have 3 shooters of varying abilities.

Each shooter fires at someone (or something) each round; there’s is fixed order as to who gets to shoot first. The one who’s allowed to shoot first is a poor shooter with an accuracy of only 30%, the second has an accuracy of 80% and the last is a sharp shooter who shoots with an accuracy of 100%. The question is that if you’re the first shooter and allowed to go first, who would you choose to shoot?

An analysis of this “game” gives us a surprising but convincing result. If you choose to shoot the average shooter, and succeed, you will definitely lose because the next in line would be the sharp shooter and he would shoot you. If you choose to shoot the sharp shooter and hit, the average shooter will shoot you, leaving you with a 20% chance of survival. And even if you survive, you only have 30% chance of hitting him later. You might say, this mediocre shooter is so lousy, he’ll probably have to lose anyways. But you can actually raise your chances of winning by choosing a more intelligent strategy: To fire into the air.

This way, the average shooter will get his turn and attempt to shoot the sharp shooter since shooting you and succeeding mean he’ll have to die when the sharp shooter’s turn comes. If he succeeds, the mediocre shooter gets to try his hands at killing the average shooter. If he fails, the sharp shooter will immediately kill him and that once again, leaves the mediocre shooter with a chance of 30% to kill the sharp shooter. The somewhat counter-intuitive strategy of shooting at no one raise the chances of the mediocre shooter winning substantially.

The principle alluded by this example is that if you’re a weak player; it is wise to allow the stronger players to make their moves and get rid of all each other before making a move and fire your best shot at the one left standing. Now that we surface the principle, the logic of such a choice becomes more intuitive.

Thinking Strategically is a great read for students who likes to think and don’t mind re-reading some of the statements in the book a couple of times to understand the explanation behind some strategic moves. It teaches an important skill of looking forward and reasoning backwards and shows you the power of its application in all sorts of “games”. The book might make you feel like you’ll become smarter but trust me, it’s not that easy to apply strategic thinking that quickly in real life and often, we need a degree of foresight that we would almost definitely lack.

Xmas Economist

This boxer day came with reads as well, ERPZ decided not to rest on the day after Christmas so here’s your reads for this holiday weekend, almost all from The Economist’s latest double issue’s Christmas Specials.

We first have Arguing till Death, a lesson for America from history’s greatest Western Philosopher, Socrates’ life. I got introduced to Aristophanes’ The Clouds through the article and is pleasantly surprised by the sort of humour ancient Greeks were capable of.

Hi There discusses politeness and courtesy in the English Language and the effect of this spread of English Language on the world today. The other talks about the virtues and motivations of being a foreigner in the world today and on the same issue is an article, A Ponzi scheme that works that looks into the migrant society of America today and the allure of it.

For viewing pleasure, How to make a splash in social media by Alex Ohanian. It’ll only require about 4 plus minutes of your attention; a short time before you dash off to the next party. Ohanian really gives a strong message about how the Internet works and how you might be able to ride on it to help you with a cause, but like what he says in the end, ‘you are not going to be in control’.

Corporate Responsibility

Corporate Social Responsibility — More ideas to have more trees

While we tinker with the idea that governments and politics are important sources of forces for the good when it comes to climate, corporations are already doing loads in the real world with the advent of Corporate Social Responsibility.

To be frank, CSR can sometimes be make-up for the company’s public face but there are still substantial number of firms who are doing real big good stuff and tackling different aspects of social costs the company might have inflicted on the society. Knowledge @ Wharton introduces the CSR moves of Campbell, which covers not only environmental actions but also social programmes (mostly to do with employees).

The Economist thinks little of CSR but highlights the ordinary good that firms and companies does by just doing their own stuff (manufacturing, marketting, improving, innovating). The newspaper argues that business people should probably trumpet these achievements of fostering innovation, cooperation between groups and individuals across the globe besides being so engrossed with CSR.

Sometimes I guess if you look on the bright side, everyone is probably doing good through being selfish – the central idea of economics.

Weekend Reads

We begin this week’s reads with an interview with Paul Samuelson by John Cassidy from The New Yorker. John Cassidy recently published a new book, How Markets Fail, which I’ll read some time soon. It won’t be that soon though – I’m still reading Thinking Strategically and moving on to Art of Strategy after that.

Eric Morris shared something about the cab industry in New York, which eventually concluded with urging for less regulation (ie. raising the supply of cab licenses or “medallions” as they’re called). One of the comments revealed a really humourous story of how the cabbie’s industry in Ireland got deregulated overnight; I shall reproduce it here:

A similar sitution existed in Ireland up to a few years ago. Change was brought about when the government went to issue more wheel chair accessable taxi licenses. The Taxi driver / owners group foolishly sued the government. They claimed that the government didn’t have the right to issue new licenses. They won but the court ruled that the government didn’t have the power to issue any licenses. The taxi ma[r]ket was deregulated overnight.

The current complaint from taxi drivers is that there are too many taxis etc etc. There were clear winners, the consumer and those new taxi drivers who are now free to ply their trade in a vastly increased taxi market.

The fact that GPS navigation on-board cars/cabs are widely available means that the tacit barrier to entry for the cab business have been significantly lowered. Anyone who can drive and have a car with on-board GPS navigation (and perhaps a meter) can technically offer good taxi services. Knowledge of the city and the different landmarks have become less of an advantage or requirement.

As for talks that you might want to listen to, Magnus Larsson speaks about structuring sand in deserts to prevent further desertification. His proposal won the Holcim Awards.

Popping Up?

With the Subprime Financial Crisis, the global economy tumbled, trade flows scaled down rapidly as economies started contracting. Initially, during the boom, trade was growing faster than global income, implying that the global growth, mainly concentrated in the already developed parts of the world economy was gained from increasing specialization and division of labour through trade and exchange. And for a slight contraction in the global economy, a lot of these supply chain will face problems in-between and go bust, resulting in a huge contraction in trade since the businesses relied on each other heavily for business. Daniel Gross discusses the decline of trade, and the implied slowdown/reverse of globalization on Slate.com. The situation is probably not as serious as Gross makes it sound.

The crisis is leading to a re-organization of globalization, towards greater degrees of cooperation and perhaps with less imbalances. With economists finding a better means of carry trade, and more reasons for Asia to get together, the world won’t be drifting apart that soon. In the latter article from Banyan column, The Economist highlights the strengths of a more integrated Asian economy and the challenges facing Asia.

The world seem to have accepted the global multilateral trade isn’t exactly going to be possible with all that decline in trade and rise of calls for protectionism and so regional multilateral trade and economic integration is the second best thing. Forming trade blocs or even common markets would do a great deal to help further globalization and put it on a path with more supranational bodies’ control. The idea is that having authorities in the process of globalization might help make it a better force in this world.

Cafe Ironies

In an entry with the same title on my blog, I detailed my experience at The Coffee Bean recently that didn’t quite start nicely but ended off pretty intellectually. I’m quoting the gist here:

I approached the counter with a maths worksheet in my hand (I was planning to work out some problems there while I sipped on the tea since I had some spare time on my hand and needed to exercise my mind) and made my order. The young man serving me immediately asked if I intended to sit around to study.

I commented that I’ll probably be around for half an hour and asked if it’ll be a problem. He replied that there’s an event downstairs and they anticipate a crowd so they discourage people from studying at the cafe. I kept quiet and took my receipt. I thought that the Large Chai Latte should at least buy me 30 minutes of time at the cafe.

This post is a discussion seeks to answer the question: “If a cafe wants to maximize their profits from a crowd and yet is limited by their available seats, how do they discourage people from studying there besides using attitude (which I assume is something I experienced)?” So before answering that question, we list out the factors that would encourage one to study at the cafe and see if there’s anything we can do to manipulate them:

Things that encourage one to study at a cafe

Good lighting; makes reading comfortable

Extremely hot or cold drink; takes you longer to drink and the taste of the drink don’t change that rapidly over time which means more excuse to stay at the cafe longer

Quality drinks; makes for nice beverage while you study and you probably won’t mind ordering one more and staying longer

Comfortable seats; allows you to study comfortably and sit at the cafe for longer time without feeling discomfort physically.

Technically speaking, removing any of these would help to reduce the time people stay around the cafe and also discourage studying. On the other hand, attitude (on part of the service staff) won’t help to reduce the determination of people studying at the cafe. In fact, it turns off people who genuinely just want to chill at the cafe for a while without discouraging the studying students. When one plans to stay at the cafe for a long time to study and sip on drinks, service at the counter makes up only a small part of the experience, whereas for customers who are interested to get a good drink and sit for a while, the service at the counter makes up half of the experience. In other words, giving people attitude is the worst possible solution compared to removing any of the above.

I strongly recommend the dimming of lighting, which doesn’t harm people out to relax but makes studying tedious and difficult. But this is not always possible since The Coffee Bean that I went to utilizes the in-building lighting that they probably have no control over. It’s not wise to compromise the quality of the drinks since it sends out the wrong messages and is disastrously difficult to control. That leaves us with modifying the seats.

I got this idea when I was at Saizeriya Restaurant at Liang Court; they feature a drinks bar where you pay about $6 bucks or so and get to drink lots of different drinks and it’s free flow – literally a drinks buffet. At first, I wondered why the seats there were so narrow and small; the cushion were thin and not exactly comfortable with prolonged sitting. Later I rationalized it as a means to get people out of the restaurant as soon as they’re done with the food. Of course it’s not going to put off people determined to try all the drinks, but at least they’ll finish with their affair and get out fast.

So here’s some prescription for cafes who hopes to attract people there for a drink and to sit around for a while (after all, if the cafe was empty you might think the drinks suck) but discourage students from spending their entire day studying there, the best move would be to adjust lighting according to your needs to adjust demand. Where this is not possible, modify the seats to make prolonged sitting uncomfortable.

Another Week

The weeks seems to be passing faster as the entries on ERPZ becomes more frequent. The one-entry-per-day rate now is not exactly very sustainable without additional support from guest writers and contributors so I’m once again calling out for interested parties to leave a comment with your emails so I might be able to contact you and get your contribution up.

This week’s reading delves into some less-read areas, namely consumer choice. Knowledge@Wharton recently ran an article about How Assortment Size Influences Healthy Consumer Choices. Earlier, they discussed how environmental cues influence consumer choice too.

The linked article mentioned about the ‘paradox of choice’, which is the topic of Barry Schwartz’s talk on TED.com. He explains the disadvantages of being offered too many choices and the problems associated with the implications of having too many choices in the first place on the psyche of the person after making the decision, citing Dan Gilbert’s presentation in the same TED conference.

Barry is another great speaker, mixing humour consistently throughout his talk with a steady flow of cartoons. The point he makes in our escalating expectations is very real and worth pondering over for anyone who wants to exert discipline on their thinking to keep their mind healthy. He claims he wrote the book, The Paradox of Choice to explain to himself why he felt worst when he got a better jeans than he previously did.

Age of Turbulence

I read the review of Alan Greenspan’s book 2 years back in The Economist, but didn’t buy it until late last year when I went on a book-shopping spree. The book gone on to stay on my book table (yes, I seriously need a bookshelf) for another year or so before I dusted it two weeks ago and began reading it. In any case, I bought an updated version, which features an epilogue detailing Alan Greenspan’s take on the Subprime Financial Crisis and his prescriptions.

I was immediately surprised by Alan Greenspan’s clear writing and simple style so contrary to his famous inscrutable public announcements about the Fed. It is this that earned The Economist’s rare praise:

Sub-heading of the book review: “Not many surprises in this memoir-cum-essay except that it is an unexpectedly enjoyable read.”

Book Review Quote: “[D]espite everything, the book turns out to be first-rate. It engages on different levels: it is intelligent in a way that few popular books on economics manage or even try to be; and, wonder of wonders, it is a good read.”

The book begins as a memoir, detailing Greenspan’s childhood, interest in music, schooling, economic/technical inclinations and his long career in the Federal Reserve Bank where he was Mr Chairman. His memoir ends somewhat abruptly in retrospect at the eleventh chapter, The Nation Challenged. Beginning with the chapter, The Universals of Economic Growth, he went on with his economy essays and analysis of various economies, industries and trends. Like what The Economist says, Age of Turbulence is a good read, his memoir was very neutral and he was very humble about his work at the Fed. His accounts of the workings of the Fed provides non-American readers a good starting point to learn about their system. Greenspan’s essays on the world economy and economics stays faithful to his belief in the power of free markets and respect for the freedoms and rights that the American Founding Fathers have sought and preserved.

He defends his views that no one can possibly identify a bubble and actively sought to burst it before it gets too big and cause a crisis in its subsequent burst. As a matter of fact, this is the case because anyone who can confidently identify the bubble can profit from it by going against the flow and thus end up defusing it before it builds up. At times, when the so-called ‘irrational exuberance’ exerts too powerful a market force then regulators wouldn’t actually be able to defuse it anyways. He seem to sigh at the voter’s expectations that the government is almighty and is disappointed by typical politicians who doesn’t seem to understand the meaning of ‘trade-offs’. These are typical economist’s perennial concerns about the world in democracies that never seem they’ll ever go away.

As a pragmatist, Greenspan shows great appreciation for the rule of law that has maintained the workings of the market and fostered a culture of trust so essential to capitalism. And reflecting on that, Greenspan gives suggestions on how the emerging economies need to improve their governance and legal systems to catch up with their prosperity and march towards developed status. These are valuable insights gained from Greenspan’s 19 years of being the Chairman of the Federal Reserve Bank. Indeed, Greenspan confesses that he knows little about international economics until he took on this role since his work at Townsend-Greenspan & Company (which closed following his nomination to that post) deals little with the economies of other nations.

Overall, Age of Turbulence provides wonderful insights into workings of the capitalist system of America and great ideas about emerging economies, the direction the world economy is heading to – knowledge significant to any economics students and economist-wannabe.

Another sort of Criticism

After penning the entry on Yuan’s appreciation, I come to observe another sort of criticism that is used on China that does contribute to the global imbalance and probably needs more attention than the currency but is an issue the Chinese government have way less control. That is the lack of spending by the Chinese, which is something repeated time and again. The Economist’s Banyan column recently compared India to China:

Levels of capital and infrastructure investment [of India] compare favourably with China’s. And, much more than in China, the hot story in India is domestic demand. India is no mercantilist adding to global imbalances. It imports more than it exports, creating much needed global demand.

Although the article goes on to discuss the flaws of the Indian economy, especially its lack of participation in the supply chains that link up much of the emerging economies of Asia as a result of their focus on exporting services rather than industrial goods. Industrial production in India remains largely in the hands of a huge number of medium-sized enterprises.

Anyways, back to the fact that China is under-consuming; James Surowiecki explains on The New Yorker why the Chinese don’t spend. He briefly ponders over culture, but goes on to focus on the nature of their economy, and the structures that are reducing access to credit and thus raising the need to save, which means perenially low consumption.

In a sense, the culture revolves around the idea of investment for the future, saving first so that one would be able to spend them. The long history of struggles and uncertainty means the Chinese are probably more risk adverse than their Western counterparts and reluctant to take on debts. In a period of growing wealth, the Chinese naturally hopes to put aside money for the future (be it studies, starting a business, a family or just for rainy days).

As the economy develops, it’ll mature and eventually shift towards higher credit and lower savings. The large investment that the government is pumping into the economy will have to induce greater efficiency in use of capital to help speed up the maturity. Till then, Americans will still get the chance to complain about Chinese inability to spend in the consumer sense.

Deflation!

The recent entries seem pretty obsessed with money markets and the more talked-about economies. I’m keeping up with my readings of The Economist and that probably explains. Following the article I previously mentioned about Japan’s looming deflation. They probed further and devoted a recent article in the leader section to the issue.

The Economist followed up with an article highlighting the problems associated with the return of deflation. Japan is encouraged to loosen their monetary policy, worry less about inflation and more about deflation. Interestingly, they even tried to draw parallels between Japan and some other developed economies’ experience today.
