Laws, Regulations and Factor Markets

The department “Laws, Regulations and Factor Markets” combines the analysis of labour and capital markets into a joint research framework. It studies how labour and capital markets interact in the provision of labour and capital for firm creation, growth and innovation. In addition, it examines how laws and regulations in the labour and capital markets affect labour and capital reallocation.

The department’s research provides unique perspectives and insights into
•    the importance of high skilled labour in promoting growth and innovation,
•    the importance of financing constraints and regulation in accessing high skilled labour markets, and
•    the impact of current and actively debated laws and regulations such as antitrust laws and gender diversity initiatives on the productivity of labour and capital.

Going Public and the Internal Organization of the Firm

Daniel Bias Benjamin Lochner Stefan Obernberger Merih Sevilir

in: Journal of Finance, forthcoming

Abstract

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.

Private Equity in the Hospital Industry

Janet Gao Yongseok Kim Merih Sevilir

in: Journal of Financial Economics, Vol. 171 (September), 2025

Abstract

We examine employment and patient outcomes at hospitals acquired by private equity (PE) firms and PE-backed hospitals. While employment declines at PE-acquired hospitals, core medical workers (physicians, nurses, and pharmacists) increase significantly. The proportion of wages paid to core workers increases at PE-acquired hospitals whereas the proportion paid to administrative employees declines. These results are most pronounced for deals where the acquirers are publicly traded PE-backed hospitals. Non-PE-backed acquirers also cut employment but do not increase core workers or reduce administrative expenditures. Finally, PE-backed acquirers are not associated with worse patient satisfaction or mortality rates compared to their non-PE-backed counterparts.

Inflation Concerns and Financial Stress

Sabrina Jeworrek Lena Tonzer

in: Economics Letters, Vol. 254 (August), 2025

Abstract

We provide evidence for a psychological component of inflation concerns. Higher inflation concerns relate in a positive and significant way to respondents’ reported levels of concerns about their financial situation. Results hold when controlling for income and financial constraints.

Cross-Subsidization of Bad Credit in a Lending Crisis

Nikolaos Artavanis Brian Lee Stavros Panageas Margarita Tsoutsoura

in: Review of Financial Studies, Vol. 38 (5), 2025

Abstract

We study the corporate-loan pricing decisions of a major, systemic bank during the Greek financial crisis. A unique aspect of our data set is that we observe both the actual interest rate and the “break-even rate” (BE rate) of each loan, as computed by the bank’s own loan-pricing department (in effect, the loan’s marginal cost). We document that low-BE-rate (safer) borrowers are charged significant markups, whereas high-BE-rate (riskier) borrowers are charged smaller and even negative markups. We rationalize this de facto cross-subsidization through the lens of a dynamic model featuring depressed collateral values, impaired capital-market access, and limit pricing.

Can Nonprofits Save Lives Under Financial Stress? Evidence from the Hospital Industry

Janet Gao Tim Liu Sara Malik Merih Sevilir

in: SSRN Working Paper, No. 4946064, 2025

Abstract

We compare the effects of external financing shocks on patient mortality at nonprofit and for-profit hospitals. Using confidential patient-level data, we find that patient mortality increases to a lesser extent at nonprofit hospitals than at for-profit ones facing exogenous, negative shocks to debt capacity. Such an effect is not driven by patient characteristics or their choices of hospitals. It is concentrated among patients without private insurance and patients with higher-risk diagnoses. Potential economic mechanisms include nonprofit hospitals' having deeper cash reserves and greater ability to maintain spending on medical staff and equipment, even at the expense of lower profitability. Overall, our evidence suggests that nonprofit organizations can better serve social interests during financially challenging times.

The Limits of Local Laws in Global Supply Chains: Extending Governance or Cutting Ties?

Michael Koetter Melina Ludolph Hendrik Keilbach Fabian Woebbeking

in: IWH Discussion Papers, No. 14, 2025

Abstract

We exploit an information shock related to the German Supply Chain Due Diligence Act and use detailed customs data to analyze how smaller, non-listed firms respond when expecting accountability for externalities beyond their organizational boundaries. Product-level regressions reveal a substantial reduction in imports from high ESG-risk production sectors. Adjustments occur mainly at the extensive margin, indicating that firms cut ties with high-risk suppliers. The product-level results translate into meaningful changes in overall international procurement for firms with Big Four auditors. Our findings suggest potential limits to mandates requiring firms to integrate broad sustainability considerations into operational decisions.

Too Poor to Be Green? The Effects of Wealth on the Residential Heating Transformation

Tobias Berg Ulf Nielsson Daniel Streitz

in: SSRN Working Paper, 2024

Abstract

Using the near-universe of Danish owner-occupied residential houses, we show that an exogenous increase in wealth significantly increases the likelihood to switch to green heating. We estimate an elasticity of one at the median of the wealth distribution, i.e., a 10% increase in wealth increase raises green heating adoption by 10%. Effects are heterogeneous along the wealth distribution: all else equal, a redistribution of wealth from rich households to poor households can significantly increase green heating adoption. We further explore potential channels of our findings (pro-social preferences, financial constraints, and luxury goods interpretation). Our results emphasize the role of economic growth for the green transition.

Inflation Concerns and Green Product Consumption: Evidence from a Nationwide Survey and a Framed Field Experiment

Sabrina Jeworrek Lena Tonzer

in: IWH Discussion Papers, No. 10, 2024

Abstract

Promoting green product consumption is one important element in building a sustainable society. Yet green products are usually more costly. In times of high inflation, not only budget constraints but also the fear that prices will continue to rise might dampen green product consumption and, hence, limit the effectiveness of exerted efforts to promote sustainable behaviors. To test this suggestion, we conducted a Germany-wide survey with almost 1,200 respondents, followed by a framed field experiment (N=500) to confirm causality. In the survey, respondents’ stated “green” purchasing behavior is, as to be expected, positively correlated with concerns about climate change. It is also negatively correlated with concerns about future inflation and energy costs, but after controlling for observable characteristics such as income and educational level only the correlation with concerns about future prices remains significant. This result is driven by individuals with below-median environmental attitude. In the framed field experiment, we use the priming method to manipulate the saliency of inflation concerns. Whereas sizably relaxing the budget constraint (i.e., by 50 percent) has no impact on the share of organic products in participants’ baskets, the priming significantly decreases the share of organic products for individuals with below-median environmental attitude, similar to the survey data.

Do Public Bank Guarantees Affect Labor Market Outcomes? Evidence from Individual Employment and Wages

Laura Baessler Georg Gebhardt Reint E. Gropp Andre Guettler Ahmet Taskin

in: IWH Discussion Papers, No. 7, 2024

Abstract

We investigate whether employees in Germany benefit from public bank guarantees in terms of employment probability and wages. To that end, we exploit the removal of public bank guarantees in Germany in 2001 as a quasi-natural experiment. Our results show that bank guarantees lead to higher employment, but lower wage prospects for employees after working in affected establishments. Overall the results suggest that employees do not benefit from bank guarantees.
