Search, Hiring Strategies, and Labor Market Intermediaries
分析搜索型劳动力市场中介的作用，发现即使中介没有技术优势，雇主在均衡中仍会使用它们来招聘，原因在于中介能分散抽样风险。
Labor market intermediaries play an important role in turnover in many labor markets. This paper analyzes one class of such intermediaries, namely, search firms. We first model the hiring decision of the firm in both succession and replacement planning. We show that employers will, in equilibrium, use search firms to find new hires even where the search firms have no technological advantage in search. This can be interpreted as being due to the search firms' ability to diversify away sampling risk.
