Does Studying Economics Inhibit Cooperation?
研究接触经济学中的自利模型是否改变人们自利行为的程度，发现经济学家表现出更多自利行为，且初步证据表明接触该模型确实鼓励自利行为。
In this paper we investigate whether exposure to the self-interest model commonly used in economics alters the extent to which people behave in self-interested ways. First, we report the results of several empirical studies—some our own, some by others—that suggest economists behave in more self-interested ways. By itself, this evidence does not demonstrate that exposure to the self-interest model causes more self-interested behavior, since it may be that economists were simply more self-interested to begin with, and this difference was one reason they chose to study economics. Second, we present preliminary evidence that exposure to the self-interest model does in fact encourage self-interested behavior.
