Legislators, of course, have different preferences about what kinds of laws to support, which can make it hard to study mechanisms of political influence precisely. But Igan and Mishra approach the problem in a clever way – they look for instances when elected officials switched their position on legislative proposals that surfaced more than once.
当然，立法者关于采用何种法律给予支持的偏好是不同的，这使得精确研究政治影响机制变得十分困难。但伊甘和米什拉用一个十分巧妙的办法处理了这个问题——他们寻找党员官员对立法建议的立场改变超过一次的例子，并花了大量精力寻找立场改变背后的原因。
