No doubt economists can learn from historians, but the search for economic regularities should not be abandoned. It is not limited to traditional economic approaches. We know much more about economics thanks to the work of Robert Axtell (computer scientist), Cesar Hidalgo (physicist), Duncan Watts (sociologist), Esther Duflo (an economist who runs the kind of controlled experiments which, according to Gideon, don’t happen in economics) and Daniel Kahneman (psychologist). All of them use those pesky “models and equations”. Are mainstream economists receptive enough to such invaders? The best ones are. The majority are not, but that is a fact about academia, not economics.
