Human Capital, Technical Change, and the Welfare State
研究人力资本分布、技术选择和再分配制度之间的相互作用，分析欧洲式福利国家和美国式自由放任体制的可持续性，以及技术变革如何影响工资不平等。
I study the interactions between the distribution of human capital, technological choice, and redistributive institutions. I first ask what makes alternative social contracts such as a European-style “welfare state” and U.S.-style “laissez-faire” sustainable, and in particular how each is affected by skill-biased technical change. I then endogenize technological or organizational choice, and show that firms respond to greater human capital heterogeneity with more flexible technologies that further exacerbate wage equality. I then analyze the simultaneous determination of technology, income distribution, and redistributive institutions, and as well as spillovers between the social contracts of different countries.
