Unemployment and Economic Welfare
构建了一个简单的理论框架，用于解释劳动力市场行为，并分析就业和失业变化在何种条件下与经济福利变化相关联。
this paper is concerned with developing a simple theoretical framework that might be used to interpret the labor market behavior described above; this interpretive device is then used to determine under what conditions changes in employment and unemployment can be associated with changes in economic welfare. The analysis proceeds in two steps. First, a basic model of employment-- nonemployment is developed and analyzed. This model is then extended to incorporate the phenomenon of unemployment. II. A Simple Model of Worker Turnover Consider an economy consisting of a fixed number of individuals. Each person has preferences given at each point in time by U = ln(c) + z, where c represents the consumption of market goods and services and z represents the consumption of services produced in the nonmarket sector
