Social Preferences, Sorting, and Competition*
研究了劳动力市场竞争加剧如何影响社会偏好对劳动力市场结果的作用，发现竞争促进工人分类但加剧租金差异，可能导致低效失业。
Abstract In this paper, I investigate how an increase in competition for workers influences the impact of social preferences on labor‐market outcomes. By sorting themselves into firms with homogeneous work forces, workers can ensure that they suffer less from social comparisons. Competition promotes choice and thus facilitates sorting. However, competition also boosts rent differences in the labor market, because firms cannot curb internal inequity among its employees without losing workers to competitors. To reduce their exposure to social comparisons, workers might engage in inefficient sorting into unemployment. Consequently, social preferences can have strong effects (i.e., unemployment) in a competitive labor market, whereas they only have a slight impact on labor‐market outcomes in a monopsony.
