Marktmacht, Inputkosten und Technologie
Im Fokus dieser Forschungsgruppe steht die empirische Analyse der Dynamik und Determinanten der wirtschaftlichen Entwicklung. Dabei wird soweit wie möglich anerkannt, dass es einzelne heterogene Unternehmen sind, die durch ihre individuellen Fähigkeiten, Innovationen hervorzubringen und Ressourcen effizient zu allokieren, die Entwicklung auf höherer Aggregationsebene bestimmen. Insgesamt kann die mikrofundierte Analyse zu einem besseren Verständnis der eigentlichen Mechanismen und der Dynamik der wirtschaftlichen Entwicklung und somit zur Entwicklung geeigneter wirtschaftspolitischer Instrumente beitragen. Beispielsweise beschäftigt sich eins der aktuellen Projekte dieser Forschungsgruppe mit den Effekten von (Import-)Wettbewerb auf Produktivität und Innovationsverhalten von Unternehmen sowie auf die Entwicklung in und von Branchen.
Die Forschungsgruppe arbeitet eng mit CompNet zusammen.

European Firm Concentration and Aggregate Productivity
in: Journal of the European Economic Association, im Erscheinen
Abstract
This paper 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 toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while 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.

Paying Outsourced Labor: Direct Evidence from Linked Temp Agency-Worker-Client Data
in: Review of Economics and Statistics, im Erscheinen
Abstract
We estimate how much firms differentiate pay premia between regular and outsourced workers in temp agency work arrangements. We leverage unique Argentinian administrative data that feature links between user firms (the workplaces where temp workers perform their labor) and temp agencies (their formal employers). We estimate that a high-wage user firm that pays a regular worker a 10% premium pays a temp worker on average only a 4.9% premium, compared to what these workers would earn in a low-wage user firm in their respective work arrangements—the midpoint between the benchmarks for insiders (one) and the competitive spot-labor market (zero).

Marginal Jobs and Job Surplus: A Test of the Efficiency of Separations
in: Review of Economic Studies, im Erscheinen
Abstract
We present a test of Coasean theories of efficient separations. We study a cohort of jobs from the introduction through the repeal of a large age- and region-specific unemployment benefit extension in Austria. In the treatment group, 18.5% fewer jobs survive the program period. According to the Coasean view, the destroyed marginal jobs had low joint surplus. Hence, after the repeal, the treatment survivors should be more resilient than the ineligible control group survivors. Strikingly, the two groups instead exhibit identical post-repeal separation behavior. We provide, and find suggestive evidence consistent with, an alternative model in which wage rigidity drives the inefficient separation dynamics.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
in: Journal of Comparative Economics, im Erscheinen
Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

What Does Codetermination Do?
in: ILR Review, Nr. 4, 2022
Abstract
The authors provide a comprehensive overview of codetermination, that is, worker representation in firms’ governance and management. The available micro evidence points to zero or small positive effects of codetermination on worker and firm outcomes and leaves room for moderate positive effects on productivity, wages, and job stability. The authors also present new country-level, general-equilibrium event studies of codetermination reforms between the 1960s and 2010s, finding no effects on aggregate economic outcomes or the quality of industrial relations. They offer three explanations for the institution’s limited impact. First, existing codetermination laws convey little authority to workers. Second, countries with codetermination laws have high baseline levels of informal worker voice. Third, codetermination laws may interact with other labor market institutions, such as union representation and collective bargaining. The article closes with a discussion of the implications for recent codetermination proposals in the United States.

TV and Entrepreneurship
in: IWH Discussion Papers, Nr. 17, 2017
Abstract
We empirically analyse whether television (TV) can influence entrepreneurial identity and incidence. To identify causal effects, we utilise a quasi-natural experiment setting. During the division of Germany after WWII into West Germany with a free-market economy and the socialistic East Germany with centrally-planned economy, some East German regions had access to West German public TV that – differently from the East German TV – transmitted images, values, attitudes and view of life compatible with the free-market economy principles and supportive of entrepreneurship. We show that during the 40 years of socialistic regime in East Germany entrepreneurship was highly regulated and virtually impossible and that the prevalent formal and informal institutions broke the traditional ties linking entrepreneurship to the characteristics of individuals so that there were hardly any differences in the levels and development of entrepreneurship between East German regions with and without West German TV signal. Using both, regional and individual level data, we show then that, for the period after the Unification in 1990 which made starting an own business in East Germany, possible again, entrepreneurship incidence is higher among the residents of East German regions that had access to West German public TV, indicating that TV can, while transmitting specific images, values, attitudes and view of life, directly impact on the entrepreneurial mindset of individuals. Moreover, we find that young individuals born after 1980 in East German households that had access to West German TV are also more entrepreneurial. These findings point to second-order effects due to inter-personal and inter-generational transmission, a mechanism that can cause persistent differences in the entrepreneurship incidence across (geographically defined) population groups.

Effects of Entrepreneurship Education at Universities
in: Jena Economic Research Papers, Nr. 25, 2012
Abstract
This study analyzes the impact of entrepreneurship education at universities on the intentions of students to become entrepreneurs or self-employed in the short-term (immediately after graduation) and in the long-term (five years after graduation). A difference-in-differences approach is applied that relates changes in entrepreneurial intentions to changes in the attendance of entrepreneurship classes in the same period. To account for a potential bias due to self-selection into entrepreneurship classes, only individuals having no prior entrepreneurial intentions are analyzed. Our results indicate a stimulating effect of entrepreneurship education on students’ intentions to become entrepreneurs or self-employed in the long-term but a discouraging effect on their intentions in the short-term. These results support the conjecture that entrepreneurship education provides more realistic perspectives on what it takes to be an entrepreneur, resulting in ‘sorting’. Overall, the results indicate that entrepreneurship education may improve the quality of labor market matches, the allocation of resources and talent, and increase social welfare. Not distinguishing between short- and long-term intentions may lead to misleading conclusions regarding the economic and social impact of entrepreneurship education.

The Impact of Government Procurement Composition on Private R&D Activities
in: Jena Economic Research Papers, Nr. 36, 2011
Abstract
This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving in-novation that incorporates industries with heterogeneous innovation sizes. Government demand in high-tech industries increases the market size in these industries and, with it, the incentives for private firms to invest in R&D. At the economy-wide level, the additional R&D induced in high-tech industries outweighs the R&D foregone in all remaining industries. The implications of the model are empirically tested using a unique data set that includes federal procurement in U.S. states. We find evidence that a shift in the composition of government purchases toward high-tech industries indeed stimulates privately funded company R&D.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
in: Jena Economic Research Papers, Nr. 2008-058, Nr. 58, 2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Hochschulen als regionaler Innovationsmotor? Innovationstransfer aus Hochschulen und seine Bedeutung für die regionale Entwicklung
in: Arbeitspapier / Hans-Böckler-Stiftung, Nr. 158, 2008
Abstract
Innovation ist der wesentliche Motor wirtschaftlicher Entwicklung. Denn vor allem die Andersverwendung von Ressourcen, weniger deren Mehreinsatz führt zu Wachstum und Wohlstand. Aus diesem Grund stellt Innovation auch einen wichtigen Ansatzpunkt für eine auf Wachstum zielende Politik dar. Dies gilt sowohl auf gesamtwirtschaftlicher Ebene als auch für einzelne Branchen und Regionen. In Innovationsprozessen stellt Wissen die entscheidende Ressource dar. Wissen ist mehr als bloße Information. Es umfasst insbesondere auch die Fähigkeit, Informationen zu interpretieren und anzuwenden bzw. ihre Anwendbarkeit einzuschätzen. Wissen ist an Menschen gebunden und lässt sich vielfach nur in direktem persönlichen Kontakt weitergeben. Aus diesem Grund hat Wissen eine regionale Dimension: Die Verfügbarkeit von Wissen hängt davon ab, wo sich die Menschen aufhalten, die über dieses Wissen verfügen. Dies ist ein wesentlicher Grund dafür, dass die Fähigkeit zur Innovation von Region zu Region wesentliche Unterschiede aufweisen kann. Für eine Politik, die auf die Stärkung der Innovationsfähigkeit von Regionen gerichtet ist, kommt den öffentlichen Forschungseinrichtungen – Universitäten, Fachhochschulen und außeruniversitären Forschungsinstituten – aus mindestens zwei Gründen zentrale Bedeutung zu: Erstens verfügen die öffentlichen Forschungseinrichtungen in besonderem Maße über innovationsrelevantes Wissen. Ihre Kernaufgabe ist es, Wissen zu produzieren, zu sammeln und weiterzugeben. Zweitens ist der Bereich der öffentlichen Forschungseinrichtungen – im Gegensatz zur privaten Wirtschaft – von der Politik direkt gestaltbar. Aus diesen Gründen stellt die Steuerung des Hochschulsektors ein zentrales Handlungsfeld der Innovationspolitik dar.
