Promotion, Turnover, Earnings, and Firm‐Sponsored Training
构建模型解释不同技术条件下劳动力流动、晋升、收入分布和企业培训的差异，关键是不对称学习机制，并成功解释了日美劳动力市场的不同模式。
I develop a model in which different technological conditions lead to distinct equilibria with different patterns in labor mobility, promotion, earning distribution, and provision of firm-sponsored training. Key is the asymmetric learning of workers' characteristics. Because of the information that is conveyed to the market by promotion, firms have incentives to adopt strategic promotion policies, which result in different patterns in the use of internal labor market. The theory explains well the differences between the Japanese and the United States labor markets.
