Redistribution, power sharing and inequality concern
构建了一个再分配政策的政治竞争模型，推导出不同收入群体的净转移支付和税后基尼系数的理论预测，并用跨国数据验证了净转移支付与初始收入差距、权力分享比例之间的显著统计关系。
Abstract 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.
