TY - RPRT AU - Bossler, Mario AU - Popp, Martin TI - Labor Demand on a Tight Leash PY - 2024/Mar/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 16837 UR - https://www.iza.org/index.php/publications/dp16837 AB - We develop a labor demand model that encompasses pre-match hiring cost arising from tight labor markets. Through the lens of the model, we study the effect of labor market tightness on firms' labor demand by applying novel shift-share instruments to the universe of German firms. In line with theory, we find that a doubling in tightness reduces firms' employment by 5 percent. Taking into account the resulting search externalities, the wage elasticity of firms' labor demand reduces from -0.7 to -0.5 through reallocation effects. In light of our results, pre-match hiring cost amount to 40 percent of annual wage payments. KW - labor demand KW - labor market tightness KW - wages KW - hiring cost KW - reallocation effects ER -
