A Model of Job and Worker Flows
构建了一个包含职位间转换和替代雇佣的均衡搜索模型，区分职位与工人流动，并研究随机匹配环境下的竞争均衡及其资源配置效率。
We develop an equilibrium search model that incorporates job-to-job transitions, exhibits instances of replacement hiring, and conceptually distinguishes between job and worker flows. We propose a notion of competitive equilibrium for random-matching environments and study the extent to which it achieves an efficient allocation of resources. The model can be used to study how the permanent incomes and employment states of individual workers evolve over time, the amount of worker turnover in excess of job reallocation, the lengths of job tenures and unemployment durations, and the size and persistence of changes in workers' incomes following displacements or job-to-job transitions.
