Mathematical finance is built on a couple of assumptions. The most fundamental of them is the one on market efficiency. Is it wise to trust this assumption? Are there limits to it? Are we operating at the right scale to ignore the shakiness of the market efficiency assumption?

People tend to follow the money gradient. When a particular field is lucrative, more people tend to end up there. During the IT boom time of the previous decade, most of the talent flowed in there. Finance also has been a not-so-strange attractor for academics. Here is a look at the culture shock associated. Another excerpt from my upcoming column in the Wilmott Magazine.

This short piece is part of a column coming up in the Wilmott Magazine. Although summarily treated as a sort of curiosity, this idea may indeed blossom into a full-length book. For that reason, you will find more posts on related topics soon. For instance, why is it that hard work does not always equate to enhanced bank balance? Why do celebrities and entrepreneurs make so much more than normal employees? Want to know? Stay tuned…

This is another series of posts based on an upcoming column of mine in the Wilmott Magazine. In this series, I will examine at the arguments for and against huge bonuses and golden parachutes. The first in the series, this post merely sets the stage for the next half a dozen. The starting point of this series is the public resignation letter by Jake DeSantis, ex-EVP at AIG, and his reasons for believing in the fairness of the huge bonus packages.
