The Electoral Politics of Extreme Policies
政府可能为了选举目的而采取极端政策，当政策变动成本高且反对党无法承诺维持现状时，这种做法能带来好处。
A government may adopt extreme policies (policies lying outside the interval between the ideal points of the political parties) for electoral purposes. It can benefit when a change in policy is costly, and when the opposing party cannot commit to maintaining the status quo.
