Labour Market Effects of International Trade When Mobility is Costly
构建并估计了一个动态结构模型，研究工人积累不完全可转移人力资本时的行业选择，发现流动成本占年均工资的10%至19%，且人力资本不完全可转移和效用成本共同解释了劳动力市场对经济冲击的缓慢调整。
I build and estimate a dynamic structural model of sectoral choices with heterogeneous workers accumulating imperfectly transferable human capital. Utility costs provide an additional barrier to mobility. Estimated by simulated minimum distance on administrative data covering the population of Danish workers, costs are found to be in the range from 10% to 19% of average annual wages. Removing permanent unobserved heterogeneity increases the utility costs by an order of magnitude. I show that both the imperfect transferability of human capital and the utility costs are important in explaining the slow adjustment of the labour market following shocks to the economy.
