本文的目的是构建一个具有在职搜寻和一般人力资本积累的均衡搜寻模型，并对其进行定量评估。在模型中，工人以不同的能力进入劳动力市场，企业的生产率也不同。由于搜索摩擦和工人的生产力差异，工资被分散。该模型生成一个简单的（日志）工资方差分解，用于衡量企业和工人的生产力差异，摩擦工资分散和工人的排序动态的重要性。我使用英国年轻工人的样本校准模型。我表明，低技能工人之间的工资不平等主要是由于他们的生产力的差异。在中等技术工人中，摩擦性工资分散和分类动态与工人的生产力差异一样重要。企业生产力的差异也是两个技能群体工资不平等的一个重要来源，并在摩擦性工资分散中占很大比例。定量地，该模型能够再现观察到的横截面工资分布，平均工资经验概况和摩擦工资离散量的数据中观察到的平均最小值比。
The objective of this paper is to construct and quantitatively assess an equilibrium search model with on-the-job search and general human capital accumulation. In the model workers enter the labour market with different abilities and firms differ in their productivities. Wages are dispersed because of search frictions and workers' productivity differentials. The model generates a simple (log) wage variance decomposition that is used to measure the importance of firm and worker productivity differentials, frictional wage dispersion and workers' sorting dynamics. I calibrate the model using a sample of young workers for the UK. I show that wage inequality among low skilled workers is mostly due to differences in their productivities. Among medium skilled workers frictional wage dispersion and sorting dynamics are, together, as important as workers' productivity differentials. Differences in firms' productivities are also an important source of wage inequality for both skill groups and account for a large share of frictional wage dispersion. Quantitatively the model is able to reproduce the observed cross-sectional wage distribution, the average wage-experience profile and the amount of frictional wage dispersion observed in the data as measured by the Mean-min ratio.
