We construct a structural model of on-the-job search in which workers differ in skills along several dimensions (cognitive, manual, interpersonal...) and sort themselves into jobs with heterogeneous skill requirements along those same dimensions. We further allow for skills to be accumulated when used, and eroded away when not used. We estimate the model using occupation-level measures of skill requirements based on O*NET data, combined with a worker-level panel from the NLSY79. We use the estimated model to shed light on the origins and costs of mismatch along the cognitive, manual, and interpersonal skill dimensions. Our results clearly suggest that those three types of skills are very different productive attributes.

多维技能，排序和人力资本积累

我们构建了一个在职搜索的结构模型，在该模型中，工人在几个维度（认知，手动，人际交往...）上的技能有所不同，并按照相同的维度将自己分类为具有不同技能要求的工作。我们进一步允许使用时积累技能，不使用时侵蚀技能。我们使用基于O * NET数据的职业级别技能要求测度，并结合NLSY79的工人级别面板，来估计模型。我们使用估计的模型来阐明沿认知，手册和人际交往技能维度错配的根源和成本。我们的结果清楚地表明，这三种技能是非常不同的生产属性。
