No. 11,

Abstract
We study the granular wage and employment effects of a German place-based policy using a research design that leverages conditionally exogenous EU-wide rules governing program parameters at the regional level. The place-based program subsidizes investments to create jobs with a subsidy rate that varies across labor market regions. The analysis uses matched data on the universe of establishments and their employees, establishment-level panel data on program participation, and regional scores that generate spatial discontinuities in program eligibility and generosity. Spatial spillovers of the program linked to changing commuting patterns can be assessed using information on place of work and place of residence, a unique feature of the data. These rich data enable us to study the incidence of the place-based program on different groups of individuals. We find that the program helps establishments create jobs that disproportionately benefit younger and less-educated workers. Funded establishments increase their wages but, unlike employment, wage gains do not persist in the long run. Employment effects estimated at the local area level are slightly larger than establishment- level estimates, suggesting limited economic spillover effects. On the other hand, spatial spillovers are large as over half of the employment increase comes from commuters. Using subsidy rates as an instrumental variable for actual subsidies indicates that it costs approximately EUR 25,000 to create a new job in the economically disadvantaged areas targeted by the program.

COVID-19 and Political Preferences Through Stages of the Pandemic: The Case of the Czech Republic
Alena Bičáková, Štěpán Jurajda
Abstract
We track the effects of the COVID-19 pandemic on political preferences through ‘high’ and ‘low’ phases of the pandemic. We ask about the effects of the health and the economic costs of the pandemic measured at both personal and municipality levels. Consistent with the literature, we estimate effects suggestive of political accountability of leaders during ‘high’ pandemic phases. However, we also find that the pandemic political accountability effects are mostly short-lived, and do not extend to the first post-pandemic elections.

Voting under Debtor Distress
Jakub Grossmann, Štěpán Jurajda
Abstract
There is growing evidence on the role of economic conditions in the recent successes of populist and extremist parties. However, little is known about the role of over-indebtedness, even though debtor distress has grown in Europe following the financial crisis. We study the unique case of the Czech Republic, where by 2017, nearly one in ten citizens had been served at least one debtor distress warrant even though the country consistently features low unemployment. Our municipality-level difference-in-differences analysis asks about the voting consequences of a rise in debtor distress following a 2001 deregulation of consumer-debt collection. We find that debtor distress has a positive effect on support for (new) extreme right and populist parties, but a negative effect on a (traditional) extreme-left party. The effects of debtor distress we uncover are robust to whether and how we control for economic hardship; the effects of debtor distress and economic hardship are of similar magnitude, but operate in opposing directions across the political spectrum.

From Rivals to Allies? CEO Connections in an Era of Common Ownership
Dennis Hutschenreiter, Qianshuo Liu
IWH Discussion Papers,
No. 7,
2025
Abstract
Institutional common ownership of firm pairs in the same industry increases the likelihood of a preexisting social connection among their CEOs. We establish this relationship using a quasi-natural experiment that exploits institutional mergers combined with firms’ hiring events and detailed information on CEO biographies. In addition, for peer firms, gaining a CEO connection from a hiring firm’s CEO appointment correlates with higher returns on assets, stock market returns, and decreasing product similarity between companies. We find evidence consistent with common owners allocating CEO connections to shape managerial decisionmaking and increase portfolio firms’ performance.

IWH-Flash-Indikator I. und II. Quartal 2025

IWH-Flash-Indikator,
No. 1,
2025
Abstract
Die deutsche Konjunktur hat zum Ende des Jahres 2024 einen weiteren Rückschlag erhalten. Das Bruttoinlandsprodukt (BIP) sank im vierten Quartal 2024 um 0,2%. Es ist damit seit Mitte 2022 auf einem leicht sinkenden Trend (vgl. Abbildung 1). Wenngleich staatliche und private Konsumausgaben zugelegt haben dürften, konnten diese die deutlich gesunkenen Exporte nicht kompensieren. Damit ging auch die Wirtschaftsleistung im Jahr 2024 insgesamt um 0,2% zurück.
In den Unternehmen hat sich die Lage zuletzt anscheinend stabilisiert, die Erwartungen verschlechtern sich jedoch weiter. Die Risiken, die von der US-Wirtschaftspolitik ausgehen, dürften die Investitionsbereitschaft der Unternehmen bremsen. Das senkt nicht nur gegenwärtig die Chancen auf eine konjunkturelle Erholung, sondern wirkt auch mittelfristig hemmend auf das Produktionspotenzial. Alles in allem wird wohl das Bruttoinlandsprodukt (BIP) laut IWH-Flash-Indikator im ersten Quartal 2025 nur wenig um 0,2% und im zweiten Quartal um 0,3% zulegen.

IWH-Flash-Indikator IV. Quartal 2024 und I. Quartal 2025

No. 4,

Abstract
Der deutsche Konjunkturmotor stottert weiter vor sich hin. Obwohl das Bruttoinlandsprodukt (BIP) im dritten Quartal 2024 um 0,2% zunahm, liegt es immer noch unter dem Niveau vom ersten Quartal 2024, da das zweite Quartal nach neuesten Zahlen weitaus schwächer ausgefallen ist als zuvor gemeldet (vgl. Abbildung 1). Der leichte Zuwachs im dritten Quartal dürfte dabei vor allem auf gestiegene staatliche und private Konsumausgaben zurückzuführen sein. In den Unternehmen ist die Stimmung weiterhin trüb und die wirtschaftspolitische Unsicherheit dürfte weiterhin hoch bleiben. Zudem belasten nach wie vor gestiegene Energie- und Lohnkosten die Investitionsbereitschaft der Unternehmen. Alles in allem dürfte das Bruttoinlandsprodukt (BIP) laut IWH-Flash-Indikator im vierten Quartal 2024 stagnieren. Für den Jahresbeginn 2025 deuten allerdings die Frühindikatoren auf eine Belebung der wirtschaftlichen Aktivitäten und einen Anstieg des BIP um 0,4% hin. Diese reflektieren jedoch noch nicht die jüngsten politischen Ereignisse in den USA und in Deutschland.

Assumption Errors and Forecast Accuracy: A Partial Linear Instrumental Variable and Double Machine Learning Approach
Katja Heinisch, Fabio Scaramella, Christoph Schult
IWH Discussion Papers,
No. 6,
2025
Abstract
Accurate macroeconomic forecasts are essential for effective policy decisions, yet their precision depends on the accuracy of the underlying assumptions. This paper examines the extent to which assumption errors affect forecast accuracy, introducing the average squared assumption error (ASAE) as a valid instrument to address endogeneity. Using double/debiased machine learning (DML) techniques and partial linear instrumental variable (PLIV) models, we analyze GDP growth forecasts for Germany, conditioning on key exogenous variables such as oil price, exchange rate, and world trade. We find that traditional ordinary least squares (OLS) techniques systematically underestimate the influence of assumption errors, particularly with respect to world trade, while DML effectively mitigates endogeneity, reduces multicollinearity, and captures nonlinearities in the data. However, the effect of oil price assumption errors on GDP forecast errors remains ambiguous. These results underscore the importance of advanced econometric tools to improve the evaluation of macroeconomic forecasts.

Abstract
Die Ankündigungen und Entscheidungen der neuen US-Regierung um den Russland-Ukraine-Konflikt und die Zollpolitik haben weltweit zu hoher Unsicherheit geführt. Im Euroraum bleibt die Konjunktur schwach. Auch die deutsche Konjunktur ist weiter im Abschwung. Das Bruttoinlandsprodukt dürfte im Jahr 2025 um 0,1% und im Jahr darauf um 1,3% zunehmen.

Labor Market Polarization and Student Debt
Sanket Korgaonkar, Elena Loutskina, Constantine Yannelis
SSRN Working Paper,
2024
Abstract
This paper uses a new empirical design to explore how labor market polarization affects individuals’ incentive to pursue education funded on the margin by student debt. We argue that the labor market polarization–where automation replaces mid-skill and mid-education-level job–changes the marginal benefits of education and training and sharpens incentives to incur student debt. We advance a new measure of labor market polarizations that allows to capture the heterogeneity of this phenomena across geographies and time. Using this measure, we find that U.S. CBSAs that experience deeper labor market polarization see an increase in student debt balances and in the number of people pursuing student debt. On average, the decline in middle-skill jobs and wages has little effect on individuals’ ability to pay down existing student debt. The effects are most pronounced in ZIP codes with lower average credit scores, lower incomes, and higher share of the minority population.
