Nr. 2,

Abstract
This paper studies the role of social connections in shaping individuals’ concerns about climate change. I combine granular climate data, region-level social network data and survey responses for 24 European countries in order to document large information spillovers. Individuals become more concerned about climate change when their geographically distant friends living in sociallyconnected regions have experienced large increases in temperatures since 1990. Exploring the heterogeneity of the spillover effects, I uncover that the learning via social networks plays a central role. Further, results illustrate the important role of social values and economic preferences for understanding how information spillovers affect individual concerns.

Selbständigkeit nach der Wiedervereinigung

In: Dossier "Lange Wege der Deutschen Einheit", Bundeszentrale für politische Bildung,
2021
Abstract
Die Zahl der Selbstständigen in Ostdeutschland (ohne Berlin) beläuft sich derzeit auf rund 600 000 und ist das Ergebnis eines über die Jahre zunehmenden Trends. Selbständigkeit wurde in der DDR kaum ein Platz eingeräumt. Zum Zeitpunkt der Wiedervereinigung besaß Ostdeutschland eine Selbständigenquote von nur rund 2,2 Prozent. Dieser Anteil hat sich 2018 auf 9,2 Prozent erhöht. Damit übersteigt die Selbständigenquote Ostdeutschlands diejenige Westdeutschlands seit dem Jahr 2013. Es gilt hierbei jedoch zu beachten, dass das Wachstum der Selbständigenanzahl insbesondere in Ostdeutschland von den Solo-Selbstständigen getragen war. Zudem bestehen im Hinblick auf die sektorale Zusammensetzung mit einem geringeren Anteil an wissensintensiven Wirtschaftszweigen als in Westdeutschland noch Unterschiede zwischen Ost- und Westdeutschland.

The (Heterogenous) Economic Effects of Private Equity Buyouts

IWH Discussion Papers,
Nr. 10,
2022
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 13% over two years after buyouts of publicly listed firms – on average, and relative to control firms – but expands 13% after buyouts of privately held firms. Post-buyout productivity gains at target firms are large on average and much larger yet for deals executed amidst tight credit conditions. A post-buyout tightening of credit conditions or slowing of GDP growth curtails employment growth and intra-firm 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.

Konjunktur aktuell: Deutschland weiter im Abschwung
Konjunktur aktuell,
Nr. 3,
2023
Abstract
Die Weltwirtschaft verliert im Herbst 2023 weiter an Schwung. Die Produktion im Verarbeitenden Gewerbe und der globale Warenhandel stagnieren, gestiegene Leitzinsen verschlechtern das Investitionsklima. Die restriktive Wirtschaftspolitik drückt vor allem die europäische Konjunktur, welche zusätzlich von der Unsicherheit durch den russischen Angriffskrieg belastet wird. In Deutschland belasten die hohe Inflation, gestiegene Zinsen, eine schwache Auslandsnachfrage und Verunsicherung unter privaten Haushalten und Unternehmen die Wirtschaft. Die konjunkturellen Risiken sind für die Bauwirtschaft besonders hoch. Alles in allem dürfte das Bruttoinlandsprodukt 2023 um 0,5% zurückgehen, für das kommende Jahr wird ein Zuwachs von 0,9% prognostiziert.

Loan Securitisation during the Transition to a Low-carbon Economy
Isabella Müller, Huyen Nguyen, Trang Nguyen

May
2023
Abstract
Banks play a crucial role in the transition to a low-carbon economy, but they also expose themselves to climate transition risk. This column shows that banks use corporate loan securitisation to shift climate transition risk to less-regulated shadow banking entities. This behaviour affects carbon premia in loan contracts. When banks can use securitisation to manage transition risk, their climate policies that target only activities reflected in their books may not be as effective as bank regulators hope for.

Konjunktur aktuell: Belebung in Dienstleistungsbranchen, aber zunächst weiter schwache Industriekonjunktur
Konjunktur aktuell,
Nr. 2,
2023
Abstract
Im Sommer 2023 deuten Stimmungsindikatoren auf einen weltweiten Aufschwung in den Dienstleistungsbranchen, die Konjunktur im Verarbeitenden Gewerbe bleibt aber schwach. Hohe Inflation und gestiegene Leitzinsen dämpfen die Konjunktur in den meisten Weltregionen. In Europa belasten auch im langjährigen Vergleich hohe Energiepreise. Insgesamt bleibt die Dynamik der Weltwirtschaft im Jahr 2023 verhalten. Die deutsche Wirtschaft wird in mäßigem Tempo expandieren, denn mit sinkender Inflation und erhöhter Lohndynamik wird der private Konsum wieder zulegen. Das Bruttoinlandsprodukt dürfte 2023 um 0,3% zurückgehen, für das kommende Jahr ist ein Zuwachs von 1,7% prognostiziert. Für 2023 ist mit einer Inflationsrate von 6,1% und für 2024 mit 2,7% zu rechnen.

Can Mentoring Alleviate Family Disadvantage in Adolescence? A Field Experiment to Improve Labor-Market Prospects
Sven Resnjanskij, Jens Ruhose, Simon Wiederhold, Ludger Woessmann
Abstract
We study a mentoring program that aims to improve the labor-market prospects of school-attending adolescents from disadvantaged families by offering them a university-student mentor. Our RCT investigates program effectiveness on three outcome dimensions that are highly predictive of adolescents later labor-market success: math grades, patience-social skills, and labor-market orientation. For low-SES adolescents, the one-to-one mentoring increases a combined index of the outcomes by half a standard deviation after one year, with significant increases in each dimension. Part of the treatment effect is mediated by establishing mentors as attachment figures who provide guidance for the future. The mentoring is not effective for higher-SES adolescents. The results show that substituting lacking family support by other adults can help disadvantaged children at adolescent age.

Abstract
We study a mentoring program that aims to improve the labor-market prospects of school-attending adolescents from disadvantaged families by offering them a university-student mentor. Our RCT investigates program effectiveness on three outcome dimensions that are highly predictive of later labor-market success: math grades, patience/social skills, and labor-market orientation. For low-SES adolescents, the mentoring increases a combined index of the outcomes by over half a standard deviation after one year, with significant increases in each dimension. Part of the treatment effect is mediated by establishing mentors as attachment figures who provide guidance for the future. Effects on grades and labor-market orientation, but not on patience/social skills, persist three years after program start. By that time, the mentoring also improves early realizations of school-to-work transitions for low-SES adolescents. The mentoring is not effective for higher-SES adolescents. The results show that substituting lacking family support by other adults can help disadvantaged children at adolescent age.

Do Larger Firms Exert More Market Power? Markups and Markdowns along the Size Distribution
Matthias Mertens, Bernardo Mottironi
IWH Discussion Papers,
Nr. 1,
2023
Abstract
Several models posit a positive cross-sectional correlation between markups and firm size, which characterizes misallocation, factor shares, and gains from trade. Accounting for labor market power in markup estimation, we find instead that larger firms have lower product markups but higher wage markdowns. The negative markup-size correlation turns positive when conditioning on markdowns, suggesting interactions between product and labor market power. Our findings are robust to common criticism (e.g., price bias, non-neutral technology) and hold across 19 European countries. We discuss possible mechanisms and resulting implications, highlighting the importance of studying input and output market power in a unified framework.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms
