The Inimitable Tiff

I do hope that the debate between standard and behavioral economics will not take the shape of an ideological battle. We would make little progress if the behavioral economists took the position that we have to throw standard economics—invisible hands, trickle-downs, and the rest of it—out with the bathwater. Likewise, it would be a shame if rational economists continue to ignore the accumulating data from research into human behavior and decision making. Instead, I think that we need to approach the big questions of society (such as how to create better educational systems, how to design tax systems, how to model retirement and health-care systems, and how to build a more robust stock market) with the dispassion of science; we should explore different hypotheses and possible mechanisms and submit them to rigorous empirical testing.
