Economists have sometimes been accused of physics-envy, but that is an utterly misleading accusation. Anyone who knows modern physics will testify that physicists care about experimental evidence, about bringing their theories into conformity with the experimental evidence, and very little about rigorous theorems and analytical lemmas.

We economists like to think of our science as akin to physics in its mathematical rigor. Quite by accident, while pursuing some research on stochastic processes, I obtained in 1995 a detailed description of the research being done by tenured and tenure-track members of the Harvard University physics department, ranked that same year in a National Research Council survey as the top physics department in the United States. Analysis of the research
