Economist John Kay has an interesting article in the FT about the Global Crisis in Economic Theory. Marketers have long held to the view that marketing only exists to the extent that the assumptions of economics are false. Nice to see an economist agreeing with this.
“Since the 1970s economists have been engaged in a grand project. The project’s objective is that macroeconomics should have microeconomic foundations. In everyday language, that means that what we say about big policy issues – growth and inflation, boom and bust – should be grounded in the study of individual behaviour. Put like that, the project sounds obviously desirable, even essential. I confess I was long seduced by it.
Most economists would claim that the project has been a success. But the criteria are the self-referential criteria of modern academic life. The greatest compliment you can now pay an economic argument is to say it is rigorous. Today’s macroeconomic models are certainly that.
But policymakers and the public at large are, rightly, not interested in whether models are rigorous. They are interested in whether the models are useful and illuminating – and these rigorous models do not score well here.
Indeed, at an early stage of the project Robert Lucas, one of its principal architects, who received the Nobel prize for his contributions, developed what is known as the Lucas critique. He argued that ordinary standards of statistical validity should not be applied to the project’s predictions. According to his colleague Thomas Sargent, Lucas was concerned that such tests rejected “too many really good models”.
Economists, like physicists, have been searching for a theory of everything. If there were to be such an economic theory, there is really only one candidate, based on extreme rationality and market efficiency. Any other theory would have to account for the evolution of individual beliefs and the advance of human knowledge, and no one imagines that there could be a single theory of all human behaviour. Not quite no one: a few deranged practitioners of the project believe that their theory really does account for all human behaviour, and that concepts such as goodness, beauty and truth are sloppy sociological constructs.
But these people discredit themselves by opening their mouths. That people respond rationally to incentives, and that market prices incorporate information about the world, are not terrible assumptions. But they are not universal truths either. Much of what creates profit opportunities and causes instability in the global economy results from the failure of these assumptions. Herd behaviour, asset mispricing and grossly imperfect information have led us to where we are today.”

COBOL turns 50 this year, but has the energy and enthusiasm of a someone much younger. Perhaps 50 is the new 30, or even the new 17!
“But are companies really relying on a half-century-old invention to handle large chunks of their dealings? Mike Madden, development service manager with the catalogue-shopping firm JD Williams, believes so.
Better known for its online stores, such as Simply Be and Fifty Plus, Madden says JD Williams remains highly dependent on Cobol applications. “We have a huge commitment to Cobol,” he says. “About 50% of our mainframe systems use it.”
Why? “Simple - we haven’t found anything faster than Cobol for batch-processing,” Madden says. “We use other languages, such as Java, for customer-facing websites, but Cobol is for order processing. The code matches business logic, unlike other languages.”

Alec Wilkinson has a nice profile in the 30 March 2009 edition of The New Yorker magazine of poker-meister Chris Ferguson. The son of a mathematician mother and a game-theorist father, Ferguson seems particularly adept at applying game theory to poker.
I had not realized until reading this article that, despite the threats of lawmakers and politicians, the legal position for online poker in the US is so strong. Arguably, the various laws against online gambling only preclude gambling on “games of chance”, or betting by spectators. Online players of poker, a game of skill and not chance, are thus exempt, at least by one interpretation of the various laws. That neither US State nor Federal Governments have yet prosecuted people for playing or facilitating online poker would seem to support this interpretation.
