Abstract
The effects of private equity buyouts on employment, productivity, and job reallocation vary tremendously with macroeconomic and credit conditions, across private equity groups, and by type of buyout. We reach this conclusion by examining the most extensive database of U.S. buyouts ever compiled, encompassing thousands of buyout targets from 1980 to 2013 and millions of control firms. Employment shrinks 12% over two years after buyouts of publicly listed firms—on average, and relative to control firms—but expands 15% after buyouts of privately held firms. Postbuyout productivity gains at target firms are large on average and much larger yet for deals executed amid tight credit conditions. A postbuyout tightening of credit conditions or slowing of gross domestic product growth curtails employment growth and intrafirm job reallocation at target firms. We also show that buyout effects differ across the private equity groups that sponsor buyouts, and these differences persist over time at the group level. Rapid upscaling in deal flow at the group level brings lower employment growth at target firms. We relate these findings to theories of private equity that highlight agency problems at portfolio firms and within the private equity industry itself.

Cross-border Transmission of Climate Policies Through Global Production Networks

IWH Discussion Papers,
No. 19,
2025
Abstract
Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through upstream and downstream linkages. Distinguishing between market-based policies, non-market regulations, and technology support, the analysis shows that foreign climate policies can enhance domestic productivity, with effects shaped by industry characteristics and operating through technological adjustment along supply chains. The results underscore the importance of accounting for international spillovers when evaluating the economic impact of environmental regulation.

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

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.

Economic recovery in Germany – but structural problems and US trade policy weigh on the economy
The German economy has picked up somewhat in the first half of 2025. This was helped by the temporary increase in demand from the US in anticipation of higher tariffs. If the US does not escalate its trade conflicts further, production in Germany according to the summer forecast of the Halle Institute for Economic Research (IWH) is likely to increase a bit (by 0.4%) in 2025, after two years of decline. In March, the IWH economists were forecasting growth of 0.1% for the current year. Growth of 1.1% is forecast for the year 2026. Similar expansion rates are to be expected for East Germany.

Private ownership boosts hospital performance
New research by the Halle Institute for Economic Research (IWH) and ESMT Berlin shows that private equity (PE) acquisitions lead to substantial operational efficiency gains in hospitals, challenging common public concerns. The study reveals that hospitals acquired by PE firms significantly reduce costs and administrative staff without increasing closure rates or harming patient care.

Geopolitischer Umbruch verschärft Krise – Strukturreformen noch dringlicher
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Klimaschutz,
No. 1,
2025
Abstract
Die deutsche Wirtschaft befindet sich weiterhin in der Krise. Der Beginn des Jahres 2025 ist geprägt von erheblichen innen- aber auch außenpolitischen Veränderungen. In Deutschland ist die wirtschaftspolitische Unsicherheit angesichts des Regierungswechsels hoch. Gleichzeitig belastet die protektionistische Handelspolitik der USA die deutsche Konjunktur. Zudem hat sich mit der neuen Regierung in den USA die Sicherheitslage in Europa verschlechtert. Vor diesem Hintergrund haben Bundestag und Bundesrat die Finanzverfassung Deutschlands grundlegend geändert und weitreichende öffentliche Verschuldungsspielräume geschaffen.
Die wirtschaftliche Schwäche in Deutschland ist nicht nur konjunktureller, sondern auch struktureller Natur. So sehen sich deutsche Unternehmen einem verstärkten internationalen Wettbewerb vor allem aus China ausgesetzt. Zudem scheint ein Teil der Produktion in der energieintensiven Industrie dauerhaft weggefallen zu sein. Eine schwindende Erwerbsbevölkerung und hoher bürokratischer Aufwand sind weitere strukturelle Schwächen, unter denen die deutsche Wirtschaft leidet.
Das Bruttoinlandsprodukt dürfte in diesem Jahr mit einem Anstieg um 0,1 % kaum mehr als stagnieren. Damit revidieren die Institute die Prognose vom Herbst 2024 recht deutlich um 0,7 Prozentpunkte nach unten. Insbesondere im Sommerhalbjahr 2025 wird inzwischen die Dynamik aufgrund der US-Zollpolitik schwächer eingeschätzt. Damit verzögert sich die erwartete Erholung. Im weiteren Prognosezeitraum dürfte eine voraussichtlich expansive Finanzpolitik die Konjunktur beleben. Im kommenden Jahr dürfte steigt das Bruttoinlandsprodukt um 1,3 %, wobei 0,3 Prozentpunkte der höheren Zahl an Arbeitstagen zu verdanken sind. Damit ist die Rate gegenüber der Herbstprognose unverändert, das Niveau der Wirtschaftsleistung ist aber 0,8 % niedriger.

Frosty prospects for the German economy
The German economy will continue to stagnate in winter 2024/2025. Industry is suffering from a loss of international competitiveness. For this reason and due to the unclear economic policy outlook, firms and consumers are holding back on spending, although incomes have increased recently. Consumer spending will only increase more strongly once the uncertainty subsides. According to the winter forecast of the Halle Institute for Economic Research (IWH), gross domestic product in Germany is expected to fall by 0.2% in 2024 and to expand by 0.4% in 2025. In September, the IWH forecast had still assumed a zero growth in 2024 and a growth of 1.0% in 2025. In East Germany, gross domestic product will increase by 0.5% both this year and in 2025.
