This paper studies the employment and productivity implications of new labor regulations in China. These new restrictions are intended to protect workers' employment conditions by, among other things, increasing firing costs and increasing compensation. We estimate a model of costly labor adjustment from data prior to the policy. We use the estimated model to simulate the effects of the policy. We find that increases in severance payments lead to sizable job creation, a significant reduction in labor reallocation and an increase in the exit rate. A policy of credit market liberalization will reduce employment, slightly increase labor reallocation and reduce exit. The estimated elasticity of labor demand is about unity so that an increase in the base wage leads to sizable job losses.

This paper studies dynamic labor demand by private and public manufacturing plants in China. It contributes along two dimensions. First, it uncovers the objectives of public enterprises and compares them to private enterprises. Second, it estimates adjustment costs of these plants and thus their (dynamic) labor demand. One of our principal findings is that public plants maximize the discounted present value of profits without a soft-budget constraint. There is strong evidence of both quadratic and linear firing costs at the plant level. Costs of adjusting hours are small and lower for private compared to public plants. The private plants operate with considerably lower quadratic adjustment costs. The higher quadratic adjustment costs of the public plants may reflect their internalization o...
