Are Unemployment and Out of the Labor Force Behaviorally Distinct Labor Force States?
检验了“失业”与“退出劳动力市场”的分类在行为上是否无意义，结果拒绝了这一假设，发现两者有不同行为方程，支持搜寻理论中失业促进求职的观点。
This paper tests the hypothesis that the classifications "unemployed" and "out of the labor force" are behaviorally meaningless distinctions. This hypothesis is rejected. Distinct behavioral equations govern transitions from out of the labor force to employment and from unemployment to employment. The evidence reported in this paper is broadly consistent with versions of search theory in which unemployment is a state that facilitates the job search process. In an Appendix, we demonstrate that log concavity of the wage-offer distribution implies that the exit rate from unemployment is an increasing function of the rate of arrival of job offers.
