We examine whether and to what extent political institutions explain different performances in income redistribution across countries. After reviewing the available data sources, the measures of income redistribution and the traditional demand side explanations of redistribution, we focus our analysis on supply side factors, like political and economic institutions, rent seeking processes and the resources and instruments available for redistribution. We provide robust empirical evidence on the association between these different factors and the observed degree of redistribution. Our analysis supports the view that – for a given demand of redistribution – political and economic institutions contribute to explain differences across countries in the observed degree of redistribution.

比较政府提供收入再分配的效率

我们研究了政治制度是否以及在多大程度上解释了各国收入再分配的不同表现。在回顾了可用的数据来源、收入再分配的措施和对再分配的传统需求侧解释之后，我们将分析重点放在供给侧因素上，例如政治和经济制度、寻租过程以及可用于再分配的资源和工具。我们为这些不同因素与观察到的再分配程度之间的关联提供了强有力的经验证据。我们的分析支持这样一种观点，即——对于给定的再分配需求——政治和经济制度有助于解释不同国家在观察到的再分配程度方面的差异。
