Attacks on Academia in America
There is a terrifying trend in this country right now of attacking academia, specifically, and free thought and intellectualism, generally. Free thought is painted as subversive, dangerous, elitist, and (strangely) conspiratorial. (That word… I do not think it means what you think it means.) Universities are accused of inefficiency and professors of becoming deadwood after tenure or of somehow “subverting the youth”. (Socrates’s accusers made a similar claim before they poisoned one of the great thinkers of the human race.) Politicians attack science to score points with religious fundamentalists and corporate sponsors.
Some elements of these feelings have always floated through the United States psyche, but in recent years it has risen to the level of a festering, suppurating, gangrenous wound in the zeitgeist of the country. Perhaps those who sling accusations at education have forgotten that the US reshaped millennia of social and economic inequity by leading the way in creating public education in the nineteenth century? Or that education has underlaid the majority of the things that have made this country great — fields in which we have led the world? Art, music, literature, political philosophy, architecture, engineering, science, mathematics, medicine, and many others? That the largest economy in the world rests on (educated) innovation, and that the most powerful military in human history is enabled by technological and engineering fruits of the educational system? That the very bones of the United States — the constitution we claim to hold so dear — was crafted by highly educated political idealists of the Enlightenment, who firmly believed that freedom and a more just society are possible only through the actions of an enlightened and educated population of voters?
From an exellent blog post by the University of New Mexico’s Terran Lane explaining why he is leaving academia for the private sector. I’ve quoted the best excerpt, but really, the whole thing is worth reading.

Truth in Advertising, Game Theory Edition
Q: Looking at the flipside, was there ever a situation in which you were pleasantly surprised at what game theory was able to deliver?
A: None. Not only none, but my point would be that categorically game theory cannot do it. Maybe somewhere in a Sherlock Holmes or Agatha Christie story there was a situation where the detective was very clever and he applied some logical trick that somehow caught the criminal, something like that. You know in America there was a programme on CBS, called Numbers, written Numb3rs, with the ‘e’ reversed. Numb3rs wanted to make people curious about mathematics through detective stories. I happened to hear about it because I had done some experimental work with Amos Tversky and Dana Heller, about the game of hide and seek. In one of the episodes they refer to the paper. Of course it was a joke, but the fact that my name was mentioned in such a programme made me very happy. But outside such programmes, I categorically cannot see any case where game theory could be helpful.
That’s from The Browser’s FiveBooks interview with Tel Aviv University’s Ariel Rubinstein, one of the world’s most prominent game theorists.
We used the textbook Rubinstein wrote with Martin Osborne in the second-semester microeconomic theory course I took during the first year of my Ph.D.
I really enjoyed going through the material (especially in contrast with the second half of the course, on general equilibrium theory). Since then, however, I have been struck time and again by the limited applicability of game theory. It’s interesting that one of the world’s leading game theorists is forthcoming about that lack of applicability.

The Education of an MBA: That Was Then, This Is Now
Earlier this week, I discussed signalling, both in the context of the recent trend toward “admitting failure” in development policy and in the context of corporate social responsibility in the business world. Wikipedia describes signalling as
The idea that one party (termed the agent) credibly conveys some information about itself to another party (the principal). For example, in Michael Spence’s job-market signalling model, (potential) employees send a signal about their ability level to the employer by acquiring certain education credentials. The informational value of the credential comes from the fact that the employer assumes it is positively correlated with having greater ability.
Not only that — the agent also has to incur a real cost in order to send the signal, otherwise the signal is simply not credible. Moreover, sending the signal need not involve any productive aim other than signalling. The classic example of signalling among economists is getting an MBA, which is costly both in terms of tuition and forgone wages.
So much for the costliness of getting an MBA. How productive is getting an MBA? Michael Ryall, who teaches at the Rotman School of Management at the University of Toronto and who guest-blogs over at orgtheory.net, has written a few excellent posts on how the content of an MBA education has changed in 30 years. Here is a good excerpt from his latest post:

#SWEDOW on Steroids
The One Laptop Per Child organization is trying something new in two remote Ethiopian villages — simply dropping off tablet computers with pre-loaded programs and seeing what happens.
The goal: to see if illiterate kids with no previous exposure to written words can learn how to read all by themselves, by experimenting with the tablet and its preloaded alphabet-training games, e-books, movies, cartoons, paintings, and other programs. Continue reading →
