The Return of History

Some brilliant scholar has to write a comprehensive history of modern economics because the evolution of this field is clearly one of the most consequential things happening in the world today.

Act I in this history would be set in the era of economic scientism: the period when economists based their work on a crude vision of human nature (the perfectly rational, utility-maximizing autonomous individual) and then built elaborate models based on that creature.
Act II would occur over the past few decades, as a few brave economists tried to move beyond this stick-figure view of humanity. Herbert Simon pointed out that people aren’t perfectly rational. Gary Becker analyzed behaviors that don’t seem to be the product of narrow self-interest, like having children and behaving altruistically. Amos Tversky and Daniel Kahneman pointed out that people seem to have common biases when they try to make objective decisions.

This part of the history would be the story of gradually growing sophistication and of splintering.


I realize Mr. Brooks is not all that popular here, but I think http://www.nytimes.com//2010/03/26/opinion/26brooks.html is worthy of a look.
