Thus was born the field of rational-choice political economy, and a style of theorizing that many political scientists readily emulated. The apparent payoff was that we could now explain why politicians did so many things that violated economic rationality.
于是，理性选择政治经济学就这样诞生了，随之诞生的是许多让政治学家亦步亦趋的理论套路。显而易见的好处是，如今我们可以解释政客为什么会做那么多违反经济理性的事情。事实上，没有一种经济失灵不能用“既得利益”四个字来解释。
