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 the specialization of human capital, based on how concentrated the knowledge used in an occupation is. Combining our measure with individual labor histories from the NLSY 79-97 and Norway’s LEED, we show that workers with more specialized human capital suffer larger earnings losses following exogenous displacement. A one standard deviation increase in pre-displacement knowledge specialization increases the earnings losses post-displacement by 3 to 4 pp per year ...

The ills suffered by displaced workers motivated several recent expansions of government programs, including the unemployment insurance system, and have spurred calls for wage insurance that would provide longerrun earnings replacement. However, while the magnitude of the losses is relatively clear, the theory of why displacement matters is scattered and somewhat undeveloped. Much of the policy discussion appears to ...
