Kahneman and Tversky and their behavioral economics stand in a long tradition of applying mathematics to human behavior. In the seventeenth century, attempts to describe rational behavior in mathematical terms run into problems with the formulation of the St. Petersburg paradox. Bernoulli’s...

The origin of prospect theory is the desire to test the intuitive statistician in the real world. The development of this theory by the cognitive psychologists Kahneman and Tversky can be traced to the formers work in cognitive psychophysics, in which deviations from average behavior are termed...

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

I consider seemingly unimportant changesin this distribution, i.e. changes which neither affect expected utility norits variance....

This paper provides arguments in favor of using subjective questions as a proxy to measure welfare and well-being. This approach makes it possible to avoid having to define welfare and well-being means and having to identify the relevant indicators. Instead, individuals themselves define their...

This paper reviews three distinct strategies in recent economics for using the concept of social identity in the explanation of individual behavior: Akerlof and Kranton’s neoclassical approach, Sen’s commitment approach, and Kirman et al.’s complexity approach. The primary focus is the...
