An Equilibrium Analysis of Optimal Unemployment Insurance and Taxation
构建了一个两期一般均衡模型，分析失业保险和负所得税的福利效应，发现个体足够同质时两者均可带来福利改进，同时实施时完全保险可行但仅在劳动供给曲线负斜率时最优。
A two-person, two-period general equilibrium model with uncertainty about second-period labor productivity is developed. The model is used to consider potential welfare (Pareto) gains from both a stylized unemployment insurance system and from a negative income tax system. Welfare gains are possible if individuals are sufficiently homogeneous. When both programs are operated simultaneously, complete insurance is always feasible but is optimal only if the labor supply curve is negatively sloped.
