Marriage stability, taxation and aggregate labor supply in the U.S. vs. Europe
利用美国和17个欧洲国家的微观数据，发现女性是工作时长跨国差异的主要来源，离婚率与女性工作时长正相关，税收与男性工作时长负相关，两者共同解释45%的劳动供给差异。
Americans work more than Europeans. Using micro-data from the United States and 17 European countries, we document that women are typically the largest contributors to the cross-country differences in work hours. We also show that there is a negative relation between taxes and annual hours worked, driven by men, and a positive relation between divorce rates and annual hours worked, driven by women. In a calibrated life-cycle model with heterogeneous agents, marriage and divorce, we find that the divorce and tax mechanisms together can explain 45% of the variation in labor supply between the United States and the European countries.
