Semi‐Nonparametric Estimation of an Equilibrium Search Model
估计了一个考虑劳动力市场部门间生产率差异的均衡工作搜索模型，将失业分为摩擦性和结构性两类，并半非参数地估计生产率分布，分析最低工资变化的影响。
We specify and estimate an equilibrium job search model with productivity differences across labour market segments. The model allows for two types of unemployment: frictional unemployment due to search frictions and structural unemployment due to wage floors. Wage floors exist because of high unemployment benefits or binding minimum wages. The productivity distribution is estimated semi‐nonparametrically along the lines of Gallant‐Nychka, using Hermite series approximation. We decompose the total unemployment rate and we examine the effects of changes in the minimum wage.
