Statistical Discrimination and Efficiency
探讨统计歧视是否构成市场失灵，发现歧视可能通过减少工人与岗位的错配带来效率提升，但最终是否采用歧视取决于专业化信息收益与投资成本增加的权衡。
This paper asks whether statistical discrimination is a market failure. I consider the problem for a utilitarian social planner who operates in an environment that can generate statistical discrimination as an equilibrium phenomenon. It is found that there are potential efficiency gains from discrimination in terms of reduced "mismatch" between workers and jobs. Whether the solution to the planning problem involves discrimination depends on the trade-off between the informational gains of specialization and the losses in terms of increased investment costs.
