Going Public and the Internal Organization of the Firm

Abstract
This paper examines how initial public offerings (IPOs) affect firms' internal organization. We find that IPO firms become more hierarchical and standardized organizations, characterized by additional layers, more managers, smaller control spans, and larger administrative functions. These changes occur mostly in preparation for the IPO and can be only partially explained by growth. IPO firms with greater human capital risk experience larger hierarchical changes. Hierarchical changes help firms standardize employee roles and formalize internal processes. Our results suggest that firms reorganize to reduce their dependence on key individuals' human capital when transitioning to public markets.

Smooth and Persistent Forecasts of German GDP: Balancing Accuracy and Stability
Katja Heinisch, Simon van Norden, Marc Wildi
IWH Discussion Papers,
No. 1,
2026
Abstract
Forecasts that minimize mean squared forecast error (MSE) often exhibit excessive volatility, limiting their practical applicability. We address this accuracy-smoothness trade-off by introducing a Multivariate Smooth Sign Accuracy (M-SSA) framework, which extracts smoothed components from leading indicators to enhance the signal-to-noise ratio and control the forecast volatility and timing. Applied to quarterly German GDP growth, our method yields smoothed forecasts that can improve forecasting accuracy, particularly over medium-term horizons. We find that while smoother forecasts tend to lag slightly around turning points, this can be offset by adjusting the forecast horizon. These findings highlight the practicality of the M-SSA framework for both forecasters and policymakers, especially in settings where forecast revisions or policy adjustments are costly.

Compliance with the EU fiscal rules requires extensive consolidation – Medium-term projection of macroeconomic developments and public finances in Germany
Germany faces considerable structural burdens from both macroeconomic and fiscal perspectives, as potential growth is likely to be significantly lower than in past decades. A projection by the Halle Institute for Economic Research (IWH) on macroeconomic developments up to the year 2040 shows that, under unchanged fiscal policies, public debt can be expected to continue rising. The federal government's fiscal-structural plan assumes compliance with EU requirements, but this is only achievable under the assumption of high global spending cuts that have not yet been specified in detail.

Die Sorge um De-Industrialisierung führt in die Irre
Reint E. Gropp
Wirtschaft im Wandel,
No. 3,
2025
Abstract
Eine der größten Sorgen sowohl der aktuellen als auch der vorhergehenden Regierung ist es, in Deutschland wichtige Industrieproduktion zu erhalten beziehungsweise neu anzusiedeln. Dabei geht es um eine breite Palette von Sektoren: Halbleiter, Batterien, Chemie, Stahl, Pharmazeutika oder Elektroautos. Basierend auf diesem Ziel werden signifikante Subventionen gerechtfertigt, etwa Einzelsubventionen in Milliardenhöhe für individuelle Unternehmen (Intel, TSMC) oder generelle Vergünstigungen wie der Industriestrompreis. Deutschland ist mit dieser Sorge nicht allein; auch die USA, die EU, Indien, Indonesien und viele weitere Länder versuchen, Anreize für inländische Produktion zu schaffen.

Slight upturn on the horizon, structural problems remain
As the year draws to a close, it remains uncertain whether the German economy is on a path to recovery, as export weakness persisted through the autumn. Nevertheless, a slight upturn is forecast for 2026, supported by fiscal stimulus and rising real incomes. According to the winter forecast of the Halle Institute for Economic Research (IWH), output is projected to grow by 1.0% in 2026, after an increase of just 0.2% in 2025. In September, the IWH economists had predicted growth of 0.8% for 2026 and 0.2% for the current year. According to this forecast, the pace of expansion in East Germany is expected to be slightly slower, mainly due to demographic factors.

Konjunktur aktuell: Leichte Belebung kommt, Strukturprobleme bleiben
Konjunktur aktuell,
No. 4,
2025
Abstract
Die internationale Konjunktur scheint Ende 2025 weiter robust, die weltwirtschaftliche Expansion dürfte sich 2026 jedoch etwas abschwächen. Nach der vorliegenden Prognose steigt die Weltproduktion 2025 um 2,7%, um im Jahr darauf um 2,4% zuzulegen. Im Euroraum dürfte sich die wirtschaftliche Expansion in geringem Tempo fortsetzen. Die deutsche Wirtschaft befindet sich auf einem fragilen Erholungskurs. Für das Jahr 2026 ist aufgrund von finanzpolitischen Impulsen und gestiegenen Realeinkommen eine leichte Belebung zu erwarten. Die Produktion dürfte im kommenden Jahr um 1,0% zunehmen, nach 0,2% im Jahr 2025.

The Geography of Worker-Firm Sorting: Drivers of Rising Colocation
Nils Torben Hollandt, Steffen Müller
IWH Discussion Papers,
No. 22,
2025
Abstract
Spatial segregation of low- and high-wage workers is a persistent economic issue with broad social implications. Using social security data and an AKM wage decomposition, this paper examines spatial wage inequality in West Germany. Spatial inequality in log wages rose sharply between 1998 and 2008, mainly due to increased variance in worker pay premiums across regions (48%) and stronger positive spatial assortative matching of workers and establishments (40%), i.e. colocation. Changes in establishment wage premia are mostly unrelated to rising colocation whereas labor mobility even reduced it. Instead, growth in worker pay premiums among stayers was concentrated in regions where high-wage workers and high-wage establishments were overrepresented already in the 1990s and, thus, magnified pre-existing colocation leading to ‘colocation without relocation’. Germany’s rising trade surplus, especially with Eastern Europe, boosted stayers’ worker pay premiums in those ex-ante high-wage regions and fully explains rising colocation.

The (Heterogeneous) Economic Effects of Private Equity Buyouts

Management Science,
Vol. 71 (11),
2025
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.

IWH-Flash-Indikator IV. Quartal 2025 und I. Quartal 2026

IWH-Flash-Indikator,
No. 4,
2025
Abstract
Die deutsche Wirtschaft stagnierte im dritten Quartal 2025, nachdem sie im Quartal zuvor noch um 0,2% geschrumpft war. Einem Rückgang der Exporte standen steigende Investitionen in Ausrüstungen gegenüber. Das Bruttoinlandsprodukt (BIP) liegt damit weiterhin mehr als einen Prozentpunkt unter dem Höchstwert von vor drei Jahren. Die anhaltende Exportschwäche der deutschen Industrie ist dabei nicht auf eine ungünstige weltwirtschaftliche Lage zurückzuführen, sondern auf weiterhin ungelöste strukturelle Probleme wie zu hohe Energie- und Arbeitskosten in Deutschland. Zwar deutet sich zum Jahreswechsel 2025/2026 eine moderate konjunkturelle Belebung an (vgl. Abbildung 1), von den geplanten Mehrausgaben für Verteidigung und Infrastruktur sind jedoch erst ab dem kommenden Jahr konjunkturelle Impulse zu erwarten. Allerdings belasten weltweite Spannungen die Lieferketten weiterhin, und sie führen in der stark arbeitsteiligen deutschen Industrie immer wieder zu Engpässen. Laut IWH-Flash-Indikator steigt das Bruttoinlandsprodukt (BIP) im vierten Quartal 2025 um 0,2% und im ersten Quartal 2026 um 0,4%.

IWH Discussion Papers,
No. 18,
2025
Abstract
This study provides new evidence on the impact of the EU Cohesion Policy on income growth in less developed regions. Our panel includes data from all European regions for the years 1989-2020. Using a fuzzy Regression Discontinuity Design, we model treatment dynamics by applying a random effects estimator. Based on digitized historical data, we precisely replicate the policy rule and correctly classify the regions’ eligibility status. Results show that the policy has a moderate positive effect on GDP per capita growth in the targeted regions.
