Negative income taxes, inequality and poverty
用一个包含异质性主体的新古典增长模型，分析负所得税制度（固定税率加全额可退还抵免）的再分配效应，发现提高抵免与产出比会显著降低不平等和贫困，但以产出大幅下降为代价。
Abstract We use a neoclassical growth model with heterogeneous agents to analyze the redistributive effects of a negative income tax system, which combines a flat rate tax with a fully refundable credit (“demogrant”). We show that changing the demogrant‐to‐output ratio causes significant changes in the distribution of income. Specifically, we find that increasing the demogrant‐to‐output ratio sharply reduces the level of inequality as well as both relative and absolute poverty (all measured in terms of post‐tax total income). However, these reductions in inequality and poverty come at the expense of a significant reduction in output.
