劳动者与雇主异质性下的均衡工资离散
- 研究问题
- 作者研究劳动者能力、企业生产率及匹配摩擦如何共同产生稳态工资差异，并量化这些因素在不同技能组中的贡献。
- 方法与思路
- 摘要称建立含在职搜寻与企业应对外部报价的均衡模型，使用法国雇主雇员匹配面板估计，并非参数估计异质性分布。
- 材料陈述的贡献
- 摘要报告工资方差的结构分解：高技能白领的个人效应份额接近四成，低技能组下降，市场不完善的贡献通常约为五成。
- 阅读关注点
- 应核对稳态、工资报价与异质性设定如何支持识别，以及非参数分布估计、方差分解定义和不同技能组结果的精度。
- 阅读边界
- 所给出版社摘要未列出完整识别假设和不确定性评估；报告份额依赖模型与样本，不能视为普遍适用的因果分解。
原文摘要
We construct and estimate an equilibrium search model with on-the-job-search. Firms make take-it-or-leave-it wage offers to workers conditional on their characteristics and they can respond to the outside job offers received by their employees. Unobserved worker productive heterogeneity is introduced in the form of cross-worker differences in a "competence" parameter. On the other side of the market, firms also are heterogeneous with respect to their marginal productivity of labor. The model delivers a theory of steady-state wage dispersion driven by heterogenous worker abilities and firm productivities, as well as by matching frictions. The structural model is estimated using matched employer and employee French panel data. The exogenous distributions of worker and firm heterogeneity components are nonparametrically estimated. We use this structural estimation to provide a decomposition of cross-employee wage variance. We find that the share of the cross-sectional wage variance that is explained by person effects varies across skill groups. Specifically, this share lies close to 40% for high-skilled white collars, and quickly decreases to 0% as the observed skill level decreases. The contribution of market imperfections to wage dispersion is typically around 50%. Copyright The Econometric Society 2002.
