Supply and Demand in a Two-Sector Matching Model
研究了技术变革如何影响工人收入分配，将工人自选部门与部门内匹配结合，分解技术变革为技能偏好变化和技能回报变化，并推导出比较静态结果。
I examine the distributional consequences of technological change in a framework that nests Roy’s (1951) and Becker’s (1973) classical models: workers self-select into two sectors and then match with heterogeneous firms within each sector. In this model, technological change can be decomposed into changes in (i) the degree to which sectors covet the same skill sets and (ii) the extent to which output varies with skill in each sector. By deriving monotone comparative statics results for each of these two types of changes, I am able to provide a comprehensive account of the distributional consequences of technological change.
