Homo economicus – that autonomous utility-maximizing creature of ancient lore – has been dead for a long, long time. Economists today drag its rotting corpse through textbooks and academic studies and econometric models in a kind of Wealth of Nations and Zombies mash-up because – well, because that’s what economists do. It’s time and then some to give the poor creature a decent burial and a proper epitaph: “Here lies Homo Economicus: Not a Bad Start, But Fatally Flawed .”
This is hardly a new or radical observation. A quick examination of the works of Ludwig Von Mises, Murray Rothbard, Herbert Simon and Gary Becker show that both the critique of homo economicus and substantive alternatives have been around in the works of respected economic theorists for over 50 years. Behavioral economists such as Amos Tversky and Daniel Kahneman have been expanding the model of the economic person since at least the 1970’s. And as New York Times columnist David Brooks points out, the economic events of 2008-2009 “exposed the shortcomings of the whole field. Economists and financiers spent decades building ever more sophisticated models to anticipate market behavior, yet these models did not predict the financial crisis as it approached. In fact, cutting-edge financial models contributed to it by getting behavior so wrong — helping to wipe out $50 trillion in global wealth and causing untold human suffering.” (March 25, 2010)
