Party Discipline and Environmental Policy: The Role of “Smoke-filled Back Rooms”*
研究发现政党纪律对环境政策严格程度的影响取决于政府腐败水平：腐败低时纪律加强政策，腐败高时纪律削弱政策。
We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high.
