We analyze a political competition model of redistributive policies. We provide an equilibrium existence result and a full characterization of the net transfers to the different income groups. We also derive several testable predictions about the way in which the net group transfers and the after-tax Gini coefficient vary with the main parameters of the model. In accordance with the theory, the empirical evidence from a sample of developed and developing democracies supports a highly statistically significant association between: (i) the net group transfer and the gap between the population and the group mean initial income, and (ii) the net group transfer (and resp., the Gini coefficient) and power sharing disproportionality. In addition, the data also provide some empirical evidence confirming a significant relationship between the net transfers to the poor (and resp., the Gini) and the concern of the political parties with income inequality.

我们分析了再分配政策的政治竞争模型。我们提供了一个均衡的存在结果，并全面描述了不同收入组的净转移。我们还得出关于网络组转移方式和税后基尼系数随模型主要参数变化的方式的一些可检验的预测。根据该理论，来自发达和发展中民主国家的样本的经验证据支持以下各项之间具有高度统计意义的关联：（i）净群体转移与人口与群体平均初始收入之间的差距，以及（ii）净集团转移（以及基尼系数）和权力分配不成比例。此外，
