Self-Selection and the Distribution of Hourly Wages
构建并估计了行业工资决定与自我选择的均衡模型，发现考虑行业特定技能异质性和自我选择能更好解释工资差异，修正的Roy模型优于经典版本。
This article formulates and estimates alternative equilibrium models of industrial wage determination and self-selection. In explaining industrial wage differentials, we find that it is important to account for heterogeneous sector-specific skills and self-selection decisions by agents concerning their sector of employment. The classical Roy model is rejected. So is an efficiency units model of the labor market. A revised Roy model that accounts for comparative advantage in the choice of industrial sectors and choice between market and nonmarket work is much more successful in explaining cross-section wage distributions and their evolution over time.
