Employment Effects of Investment Grants and Firm Heterogeneity – Evidence from a Staggered Treatment Adoption Approach
Eva Dettmann, Mirko Titze, Antje Weyh
IWH Discussion Papers,
This study estimates the establishment-level employment effects of investment grants in Germany. In addition to the average treatment effect on the treated, we analyse the influence of establishment’s characteristics and economic environment on the magnitude of the effect. We apply a modification of Heckman’s matching and difference-in-differences approach to consider time-varying treatment and different treatment durations. Our results suggest that investment grants positively impact employment. Moreover, we find strong evidence for effect heterogeneity regarding firms’ internal characteristics as well as the economic environment.
Going Public and the Internal Organization of the Firm
Daniel Bias, Benjamin Lochner, Stefan Obernberger, Merih Sevilir
SSRN Working Paper,
We examine how firms adapt their organization when they go public. To conform with the requirements of public capital markets, we expect IPO firms to become more organized, making the firm more accountable and its human capital more easily replaceable. We find that IPO firms transform into a more hierarchical organization with smaller departments. Managerial oversight increases. Organizational functions dedicated to accounting, finance, information and communication, and human resources become much more prominent. Employee turnover is sizeable and directly related to changes in hierarchical layers. New hires are better educated, but younger and less experienced than incumbents, which reflects the staffing needs of a more hierarchical organization. Wage inequality increases as firms become more hierarchical. Overall, going public is associated with a comprehensive transformation of the firm's organization which becomes geared towards efficiently operating a public firm.

Micro-mechanisms behind Declining Labor Shares: Rising Market Power and Changing Modes of Production
International Journal of Industrial Organization,
I derive a micro-founded framework showing how rising firm market power on product and labor markets and falling aggregate labor output elasticities provide three competing explanations for falling labor shares. I apply my framework to 20 years of German manufacturing sector micro data containing firm-specific price information to study these three distinct drivers of declining labor shares. I document a severe increase in firms’ labor market power, whereas firms’ product market power stayed comparably low. Changes in firm market power and a falling aggregate labor output elasticity each account for one half of the decline in labor's share.
