Are Political Economists Selfish or Indoctrinated?

Most professional economists believe that economists in general are more selfish than other people and that this increased selfishness is due to economics education. This article offers empirical evidence against this widely held belief. Using a unique data set about giving behavior in connection with two social funds at the University of Zurich, it is shown that economics education does not make people act more selfishly. Rather, this natural experiment suggests that the particular behavior of economists can be explained by a selection effect.
