Lo que sé

"What economists are really trying to get at when they highlight the importance of incentives is the fact that people aren’t stupid. (Or that even if they’re stupid, they’re not idiots.) The commitment to consequentialism is largely a distraction, as is the methodological privileging of extrinsic motives. What really matters is an awareness of the fact that large-scale social patterns are an aggregate effect of individual choices, and that the way individuals choose is highly sensitive to local context and situation. Because of this, changes in the environment (brought about, for example, by public policy) can have unexpected consequences."
