中文摘要
我们评估了基于 (对经济学家而言) 不可观测特征的劳动力市场匹配均衡模型的经验内容。具体而言, 我们从理论上证明: 基于绝对优势的 Becker (1973) 经典匹配模型 (含搜寻摩擦), 其所有参数均可仅凭关于工资与劳动力市场流动的匹配雇主–雇员数据进行非参数识别。其中, 这些数据足以对任意单个劳动者与任一给定企业相匹配时的产出进行非参数估计。我们的识别证明是构造性的, 并针对现有数据集的局限提供了实现识别策略的计算算法。最后, 我们在模型中加入在职搜寻, 扩展识别策略, 并将其应用于一个大型德国匹配雇主–雇员数据集, 以刻画详细的匹配模式和生产函数的性质。
Abstract
We assess the empirical content of equilibrium models of labor market sorting based on unobserved (to economists) characteristics. In particular, we show theoretically that all parameters of the classic model of sorting based on absolute advantage in Becker, 1973 with search frictions can be nonparametrically identified using only matched employer–employee data on wages and labor market transitions. In particular, these data are sufficient to nonparametrically estimate the output of any individual worker with any given firm. Our identification proof is constructive and we provide computational algorithms that implement our identification strategy given the limitations of the available data sets. Finally, we add on-the-job search to the model, extend the identification strategy, and apply it to a large German matched employer–employee data set to describe detailed patterns of sorting and properties of the production function.
