摘要

本文研究了知识专业化对置换后收入损失的影响。我们开发了一种基于与职业无关的知识领域份额的人力资本专业化的新措施。将我们的测量与NLSY的个人劳动历史相结合，我们表明，人力资本专业化程度比平均水平高出一个标准差的工人，在外源性流离失所后，每年的收入损失比平均水平高出4.8个百分点。较长的平均失业时间和职业降级是解释专业化对流离失所后收入的负面影响的两种机制。

The Hedgehog’s curse: Knowledge specialization and displacement loss

This paper studies the impact of knowledge specialization on earnings losses following displacement. We develop a novel measure of human capital specialization based on the share of knowledge areas that are irrelevant for an occupation. Combining our measure with individual labor histories from the NLSY, we show that workers with human capital specialization one standard deviation larger than average suffer earnings losses 4.8 percentage points larger than average per year following exogenous displacement. A longer average duration of non-employment spells and occupational downgrading are the two mechanisms that explain the negative effect of specialization on post-displacement earnings.
