POLICY ANALYSIS IN A MATCHING MODEL WITH INTENSIVE AND EXTENSIVE MARGINS*
构建了一个结合劳动供给经典模型与匹配模型的分析框架，同时考虑就业率（广延边际）和人均工时（集约边际），评估税收、转移支付和就业规制对这两个边际的影响。
The large differences in hours of work across rich countries reflect large differences in both employment to population ratios and hours per worker. We imbed the canonical model of labor supply into a matching model to produce a model with operative intensive and extensive margins, and assess the implications of several policies for changes along the two margins. Tax and transfer policies lead to decreases along both margins, whereas regulations that increase the cost of creating or maintaining a job may lead to decreases in employment, but necessarily lead to increases in hours per worker.
