Matching and Price Competition
构建了一个企业先设定固定薪资再与工人匹配的模型，发现工资低于竞争均衡但利润几乎等量上升，效率损失很小，且优秀企业获益最多、工资差距缩小。
We develop a model in which firms set impersonal salary levels before matching with workers. Wages fall relative to any competitive equilibrium while profits rise almost as much, implying little inefficiency. Furthermore, the best firms gain the most from the system while wages become compressed. In light of our results, we discuss the performance of alternative institutions and the recent antitrust case against the National Resident Matching Program.
