Strukturwandel und Produktivität

Die Abteilung Strukturwandel und Produktivität untersucht Prozesse strukturellen Wandels, die beispielsweise durch Globalisierung oder technologische Neuerungen erzeugt werden können. Struktureller Wandel führt zu Aufschwung und Niedergang von Regionen, Wirtschaftszweigen und Betrieben und hat direkte Konsequenzen für die betroffenen Arbeitnehmer und Arbeitnehmerinnen. Wir erforschen die Auswirkungen strukturellen Wandels empirisch mit Hilfe mikroökonometrischer Verfahren. Die Abteilung stellt zudem das Sekretariat des Competitiveness Research Network (CompNet), einem Zentrum für Forschung und Politikberatung rund um die Themen Wettbewerbsfähigkeit und Produktivität. Sie koordiniert darüber hinaus  MICROPROD (EU Horizon 2020).

Im Fokus unserer Arbeit stehen Produktivität, Innovationstätigkeit und Arbeitsmarktergebnisse wie zum Beispiel Beschäftigung und Lohnniveau. Ein besonderes Augenmerk liegt auf dem Transformationsprozess in Ostdeutschland. Diese wissenschaftlich und wirtschaftspolitisch relevanten Forschungsfragen werden durch die Abteilung im Forschungscluster "Institutionen und soziale Normen" sowie im Forschungscluster "Produktivität und Innovationen" analysiert.

Immigration and Entrepreneurship in the United States

Pierre Azoulay Benjamin Jones J. Daniel Kim Javier Miranda

in: American Economic Review: Insights, im Erscheinen

Abstract

Immigration can expand labor supply and create greater competition for native-born workers. But immigrants may also start new firms, expanding labor demand. This paper uses U.S. administrative data and other data resources to study the role of immigrants in entrepreneurship. We ask how often immigrants start companies, how many jobs these firms create, and how these firms compare with those founded by U.S.-born individuals. A simple model provides a measurement framework for addressing the dual roles of immigrants as founders and workers. The findings suggest that immigrants act more as "job creators" than "job takers" and that non-U.S. born founders play outsized roles in U.S. high-growth entrepreneurship

Innovation Cooperation in East and West Germany: A Study on the Regional and Technological Impact

Uwe Cantner Alexander Giebler Jutta Günther Maria Kristalova Andreas Meder

in: International Journal of Computational Economics and Econometrics, im Erscheinen

Abstract

In this paper, we investigate the impact of regional and technological innovation systems on innovation cooperation. We develop an indicator applicable to regions, which demonstrates the relative regional impact on innovation cooperation. Applying this method to German patent data, we find that regional differences in the degree of innovation cooperation do not only depend on the technology structure of a region but also on specific regional effects. High-tech oriented regions, whether east or west, are not automatically highly cooperative regions. East German regions have experienced a dynamic development of innovation cooperation since re-unification in 1990. Their cooperation intensity remains higher than in West German regions.

The Urban Wage Premium in Imperfect Labor Markets

Boris Hirsch Elke J. Jahn Alan Manning Michael Oberfichtner

in: Journal of Human Resources, im Erscheinen

Abstract

Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from greater competition in denser labor markets. We show that employers possess less wage-setting power in denser markets. We further document that an important part of the observed urban wage premia can be explained by greater competition in denser labor markets.

Mission, Motivation, and the Active Decision to Work for a Social Cause

Sabrina Jeworrek Vanessa Mertins

in: Nonprofit and Voluntary Sector Quarterly, im Erscheinen

Abstract

The mission of a job affects the type of worker attracted to an organization but may also provide incentives to an existing workforce. We conducted a natural field experiment with 246 short-term workers. We randomly allocated some of these workers to either a prosocial or a commercial job. Our data suggest that the mission of a job has a performance-enhancing motivational impact on particular individuals only, those with a prosocial attitude. However, the mission is very important if it has been actively selected. Those workers who have chosen to contribute to a social cause outperform the ones randomly assigned to the same job by about half a standard deviation. This effect seems to be a universal phenomenon that is not driven by information about the alternative job, the choice itself, or a particular subgroup.

Urban Occupational Structures as Information Networks: The Effect on Network Density of Increasing Number of Occupations

Shade T. Shutters José Lobo Rachata Muneepeerakul Deborah Strumsky Charlotta Mellander Matthias Brachert Teresa Farinha Luis M. A. Bettencourt

in: Plos One, im Erscheinen

Abstract

Urban economies are composed of diverse activities, embodied in labor occupations, which depend on one another to produce goods and services. Yet little is known about how the nature and intensity of these interdependences change as cities increase in population size and economic complexity. Understanding the relationship between occupational interdependencies and the number of occupations defining an urban economy is relevant because interdependence within a networked system has implications for system resilience and for how easily can the structure of the network be modified. Here, we represent the interdependencies among occupations in a city as a non-spatial information network, where the strengths of interdependence between pairs of occupations determine the strengths of the links in the network. Using those quantified link strengths we calculate a single metric of interdependence–or connectedness–which is equivalent to the density of a city’s weighted occupational network. We then examine urban systems in six industrialized countries, analyzing how the density of urban occupational networks changes with network size, measured as the number of unique occupations present in an urban workforce. We find that in all six countries, density, or economic interdependence, increases superlinearly with the number of distinct occupations. Because connections among occupations represent flows of information, we provide evidence that connectivity scales superlinearly with network size in information networks.

The Impact of Delay: Evidence from Formal Out-of-Court Restructuring

Randall K. Filer Dejan Kovač Jacob N. Shapiro Stjepan Srhoj

in: IWH Discussion Papers, Nr. 10, 2021

Abstract

Bankruptcy restructuring procedures are used in most legal systems to decide the fate of businesses facing financial hardship. We study how bargaining failures in such procedures impact the economic performance of participating firms in the context of Croatia, which introduced a „pre-bankruptcy settlement“ (PBS) process in the wake of the Great Recession of 2007 - 2009. Local institutions left over from the communist era provide annual financial statements for both sides of more than 180,000 debtor-creditor pairs, enabling us to address selection into failed negotiations by matching a rich set of creditor and debtor characteristics. Failures to settle at the PBS stage due to idiosyncratic bargaining problems, which effectively delays entry into the standard bankruptcy procedure, leads to a lower rate of survival among debtors as well as reduced employment, revenue, and profits. We also track how bargaining failures diffuse through the network of creditors, finding a significant negative effect on small creditors, but not others. Our results highlight the impact of delay and the importance of structuring bankruptcy procedures to rapidly resolve uncertainty about firms‘ future prospects.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior

Sabrina Jeworrek Joschka Waibel

in: IWH Discussion Papers, Nr. 8, 2021

Abstract

Around the globe, the COVID-19 pandemic has turned daily live upside down since social distancing is probably the most effective means of containing the virus until herd immunity is reached. Social norms have been shown to be an important determinant of social distancing behaviors. By conducting two experiments and using the priming method to manipulate social isolation recollections, we study whether social distancing has in turn affected norms of prosociality and norm compliance. The normative expectations of what behaviors others would approve or disapprove in our experimental setting did not change. Looking at actual behavior, however, we find that persistent social distancing indeed caused a decline in prosociality – even after the relaxation of social distancing rules and in times of optimism. At the same time, our results contain some good news since subjects seem still to care for norms and become more prosocial once again after we draw their attention to the empirical norm of how others have previously behaved in a similar situation.

European Firm Concentration and Aggregate Productivity

Tommaso Bighelli Filippo di Mauro Marc Melitz Matthias Mertens

in: IWH Discussion Papers, Nr. 5, 2021

Abstract

This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Organised Labour, Labour Market Imperfections, and Employer Wage Premia

Sabien Dobbelaer Boris Hirsch Steffen Müller Georg Neuschäffer

in: Tinbergen Institute Discussion Paper, Nr. 20, 2020

Abstract

This paper examines how collective bargaining through unions and workplace co-determination through works councils shape labour market imperfections and how labourmarket imperfections matter for employer wage premia. Based on representative Germanplant data for the years 1999{2016, we document that labour market imperfections arethe norm rather than the exception. Wage mark-downs, that is wages below the marginalrevenue product of labour rooted in employers' monopsony power, are the most prevalentoutcome. We further nd that both types of organised labour are accompanied by asmaller prevalence and intensity of wage mark-downs whereas the opposite holds for wagemark-ups, that is wages above the marginal revenue product of labour rooted in workers'monopoly power. Finally, we document a close link between our production-based labourmarket imperfection measures and employer wage premia. The prevalence and intensityof wage mark-downs are associated with a smaller level and larger dispersion of premiawhereas wage mark-ups are only accompanied by a higher premium level.
