Employer-Employee Interaction and the Duration of Unemployment
从筛选、正式搜索理论和搜索强度三种视角出发，构建了一个统一的失业退出概率模型，并用1970年人口普查就业调查数据验证了三种视角的解释力。
This paper identifies three alternative approaches to the duration of unemployment—the screening, the formal search theory, and the intensity of search approaches. From these approaches, a unified model of the weekly probability of leaving unemployment (WPOLU) is developed. In this model, WPOLU is the product of the weekly probability of job vacancy location, the probability of offer extension, and the probability of offer acceptance. The determinants of these probabilities are analyzed. The model is tested with data from the 1970 Census Employment Survey. Evidence supporting all three approaches is found. An eclectic view of unemployment is called for.
