Fixed search costs, that is, costs that do not vary with search duration, can amplify the cyclical volatility of the labor market. To assess the size of fixed costs, we analyze the relation between search costs and search duration using German establishment data. An instrumental variable estimation shows no relation between search duration and search costs. We conclude that search costs are mainly fixed costs. Furthermore, we show that a search and matching model, calibrated for Germany with fixed costs close to 75%, can generate labor market volatility that is consistent with the data.
We are grateful to Anja Bauer, Christian Merkl, Christian Offermanns, Enzo Weber, Jeffrey Wooldridge, and Josef Zweimuller for their valuable suggestions and discussion. We would also like to thank the participants of the IAB PhD Workshop 2017, the FAU-IAB Seminar on Macroeconomics and Labor Markets, and the Annual Congress of the German Economic Association 2017 for useful comments. We are grateful to the IAB team that conducts the Vacancy Survey for the support and the opportunity to introduce questions on search costs. The survey data used are confidential but not exclusive. Access to the data is provided by the Research Data Centre of the German Federal Employment Agency. For details, see http://fdz.iab.de/en/FDZ_Establishment_Data/IAB_Job_Vacancy_Survey.aspx.
