People to Watch- David Berlinski

He is the author of numerous books, including The Devil’s Delusion: Atheism and It Scientific Pretensions (Crown Forum, 2008; Basic Books, 2009), Infinite Ascent: A Short History of Mathematics for the Modern Library series at Random House (2004), The Secrets of the Vaulted Sky (Harcourt, 2003), The Advent of the Algorithm (Harcourt Brace, 2000), Newton’s Gift (Free Press, 2000), and A Tour of the Calculus (Pantheon, 1996). William F. Buckley Jr. said of The Devil’s Delusion that “Berlinski’s book is everything desirable; it is idiomatic, profound, brilliantly polemical, amusing, and of course vastly learned.

Schelling Quote- The Very Basics of Game Theory

"If I go downstairs to investigate a noise at night, with a gun in my hand, and find myself face to face with a burglar who has a gun in his hand, there is a danger of an outcome that neither of us desires. Even if he prefers to just leave quietly, and I wish him to, there is danger that he may think I want to shoot, and shoot first."


via David Henderson

The Lesson: 'in thinking through various actions you might take to have an effect on B, ask yourself how you would respond to such actions if you were B. In other words, put yourself in the other person's shoes, not to get a touchy, feely, we're-all-in-this together Kumbaya moment, but to come up with your most-realistic analysis'

John Kay's ‘long walk’ problems


For years, I have identified what I think of as ‘long walk’ problems - knotty issues that are best tackled if you can get away from it all. I often come back with an answer, or a few paragraphs, composed in my head.

Assorted Writing Tips

Stiglitz the Omniscient;
When writing a novel, one of the things you have to decide is point of view. If you focus on one character, your point of view might be limited to what that character sees.

One point of view for the author to take is that of an omniscient observer. As you read, you know that the author knows what is coming (you keep getting hints) and understands all sorts of things that the characters are innocent about.

Stiglitz always writes as the omniscient observer. He knows exactly what should have been done to prevent or solve each of the 100 financial crises that he cites.

This omniscient-observer vantage point has its limits. It does not convey the uncertainty and trade-offs that policymakers face in real time. For example, as the housing bubble was inflating, there were not many Congressional voices raised against lending to first-time homebuyers.



From NYT's Paper Cuts;

The Economist article contained a passage that would never pass muster in an American news story:

“Recently, independent voters passed Republicans to become the biggest group in the state. Some of this is due to Colorado’s growing Hispanic population, some of it is due to Californians and some of it reflects the general unpopularity of the national Republican Party. But there is a more important reason for the Republicans’ woes: their elected representatives are bonkers.”


To most American readers, that last sentence certainly looks like an opinion, and should never be presented as news in a responsible publication. (As an editor, I’d never let it get through.) But consider this: what if Colorado’s congressional delegation really is bonkers, and the Economist correspondent was merely doing his job by informing his readers of that “fact.” Sometimes judgments, even if they aren’t as solid as hard facts, are more than merely matters of opinion.


A long goodbye;

It seems fitting to begin with the ancestors. One of the exceptional characteristics of this newspaper is the degree to which it still follows the principles and methods begun 163 years ago by its founder, James Wilson, and perfected by his son-in-law, Walter Bagehot. The Economist was launched to campaign for free trade and all forms of liberty, what proponents and detractors alike today call globalisation, blended with what George Bush likes to call “the freedom agenda”. It did so with a formula that was three parts factual description and one part strongly held opinion or argumentative analysis. That is what we continue to attempt today.

We do not do so merely out of loyalty to our founders: if those principles had turned out to be wrong, they would have been ditched long ago. And their application must always evolve. I, for one, had Bagehot grumbling in his grave when, in 1994, we declared the British monarchy to be “an idea whose time has passed”, in flat contradiction to his great 1867 book, “The English Constitution”. But in general what is striking about the past 13 years is how strongly this period has fitted Wilson's original view, how it made his principles feel more relevant than ever, and how in some respects our world is one whose issues he would have recognised.


Writing resources;
I would recommend them in the following order:

1. William I. Strunk Jr. and E.B. White, “The Elements of Style”

2. William Zinsser, “On Writing Well”

3. Deirdre N. McCloskey, “Economical Writing”

4. Keith Hjortshoj, “The Transition to College Writing“

Explainer on Turkey Crisis

So people can wear tank-tops to the universities?

Sure, no problem with that. When we talk about Turkish secularism it's almost a misnomer. It's not the secularism that we enjoy here in the United States, where people can wear whatever religious garb they want. In Turkey, the authorities are directly involved in controlling religion. The state is directly involved in engaging surveillance of the public sphere to ensure that religion doesn't enter the public sphere. And that's the difference. It's state control of religion to enforce this principle that religion shouldn't enter the public sphere.

Angus Maddison on Chinese Growth

Measuring China’s Economic Performance (subscription required)
Angus Maddison & Harry X. Wu
China is the world’s fastest growing economy and is also the second largest. However, the official estimates of the Chinese National Bureau of Statistics exaggerate GDP growth and need adjustment to conform to international norms as set out in the 1993 System of National Accounts (SNA). This paper presents and discusses the necessary adjustments. The two major contributions are new volume indices for the industrial sector and for "non-material" services. Finally, in order to measure the level of Chinese GDP in internationally comparable terms, the authors use a measure of purchasing power parity (PPP) instead of the exchange rate.

Calvo vs Krugman;

Guillermo Calvo is one of my favorite economists. But — you know there had to be a but — I just don’t buy his latest missive. Still, it’s important that we have this debate: something awesome is happening to oil and other commodities, and figuring out what it means is crucial

What Happens if We’re Wrong?;
The key word is “consequences.” I learned this lesson many years ago from studying Blaise Pascal, a French mathematical genius in the 17th century who spelled out the laws of probability more clearly than anyone before him. This was a thunderclap of an insight that, for the first time, gave humanity a systematic way of thinking about the future.

Pascal was both a gambler and a religious zealot. One day he asked himself how he would handle a bet on whether “God is or God is not.” Reason could not answer. But, he said, we can choose between acting as though God is or acting as though God is not.

Suppose we bet that God is, and we lead a life of virtue and abstinence, and then the day of reckoning comes and we discover that there is no God. Well, life was still tolerable even if less fun than we might have liked. Here, the consequences of being wrong would be acceptable to most people.

Suppose, however, we bet that God is not, and lead a life of lust and sin, and then it turns out that God is. Now being wrong has put us into big trouble.

RISK management, then, should be a process of dealing with the consequences of being wrong. Sometimes, these consequences are minimal — encountering rain after leaving home without an umbrella, for example. But betting the ranch on the assumption that home prices can only go up should tell you the consequences would be much more than minimal if home prices started to fall.

Understanding Uncertainty

Maths Pocast of the Day

Probability;
Heads or tails? It’s a simple question with a far from simple answer. One that takes us into the strange and complex world of probability.

Probability is the field of maths relating to random events and, although commonplace now, the idea that you can pluck a piece of maths from the tumbling of dice, the shuffling of cards or the odds in the local lottery is a relatively recent and powerful one. It may start with the toss of a coin but probability reaches into every area of the modern world, from the analysis of society to the decay of an atom.

World Bank Scorpions;
Also on Monday, the bank announced the retirement of Praful Patel, its vice president for the South Asia region. This was ahead of the mandatory retirement age of 62 but for the credibility of the bank not a moment too soon. Mr. Patel is the man who presided over $570 million in corrupted World Bank health-sector projects in India, which we first reported on in January1. President Robert Zoellick would have sent a stronger signal that such performance won't be tolerated had he fired Mr. Patel outright rather than allowing him to slink out the back door. But at the World Bank, the main deeds that are punished are good ones.
