Abstract
This paper provides new causal evidence on how patent allowances affect firms and their employees based on quasi-random assignment of patent applications to examiners. Exploiting employer-employee records with newly linked German firm data and web-scraped patent documents, we show that patent-induced shocks reduce firm exit, improve productivity, and increase wages, with rent-sharing elasticities between 0.10 and 0.21. Wage gains are broadly observed across occupational tasks, with high heterogeneity: managers benefit disproportionately in publicly traded firms, whereas broader wage increases accrue to workers in non-traded firms. Our findings highlight the role of institutional features and firm organization in shaping how rents are shared.

Voice at Work

Abstract
We estimate the effects of worker voice on productivity, job quality, and separations. We study the 1991 introduction of a right to worker representation on boards or advisory councils in Finnish firms with at least 150 employees, designed primarily to facilitate workforce-management communication. Consistent with information sharing theories, our difference-in-differences design reveals that worker voice slightly raised labor productivity, firm survival, and capital intensity. In contrast to the exit-voice theory, we find no effects on voluntary job separations, and at most small positive effects on other measures of job quality. A 2008 introduction of shop-floor representation had similarly limited effects.

Do Politicians Affect Firm Outcomes? Evidence from Connections to the German Federal Parliament

IWH Discussion Papers,
No. 15,
2024
Abstract
We examine how connections to German federal parliamentarians influence firm dynamics using a novel dataset linking politicians and election candidates to the universe of firms. To identify the causal effects of political access, we exploit (i) new appointments to the company leadership team and (ii) discontinuities around the marginal seat of party election lists. Results reveal that political connections reduce firm exits and gradually increase employment growth, with heterogeneous productivity effects depending on the political mandate. Incorporating data on credit ratings, subsidies, and procurement contracts allows us to identify the mechanisms driving the effects over the politician’s career.

Committing to Grow: Employment Targets and Firm Dynamics

No. 17,
2023
Abstract
We study the firm-level and aggregate effects of government-imposed employment targets. We develop a dynamic general equilibrium model with heterogeneous firms and endogenous productivity growth in which penalties for below-target hiring generate a polarization mechanism: low-productivity firms exit, while others expand employment beyond efficient levels, and firms invest in productivity to avoid future penalties. We test and confirm the model’s firm level predictions using unique contractual data on more than 18,000 employment commitments from the East German privatization, exploiting quasi-random variation in the assignment of privatizers to firms. Quantitatively, employment targets reduce unemployment in the short run, but these gains reverse over time as distorted labor allocations and weakened investment incentives slow aggregate productivity growth and reduce welfare. We also evaluate how alternative designs for employment-protection (e.g., the choice between mandates and subsidies, the structure of targets) impact misallocation and the resulting short- and long-run outcomes.
