Market Power, Input Costs, and Technology

The research group deals with the empirical analysis of the dynamics and determinants of economic development. Thereby, we recognize that these are individual heterogeneous firms with their specific capabilities to innovate and to efficiently allocate scarce resources that shape patterns at higher level of aggregation (e.g. cause structural change). While following a micro-level approach we aim at adding to the understanding of the actual mechanisms and dynamics in the development of economies as well as for the development of policy instruments. For instance, one of the current research projects deals with the effect of import competition on the productivity and innovating behaviour of firms as well as on the dynamic in and of industries

The research group works closely together with CompNet.

Does the Technological Content of Government Demand Matter for Private R&D? Evidence from US States

Viktor Slavtchev Simon Wiederhold

in: American Economic Journal: Macroeconomics, No. 2, 2016

Abstract

Governments purchase everything from airplanes to zucchini. This paper investigates the role of the technological content of government procurement in innovation. In a theoretical model, we first show that a shift in the composition of public purchases toward high-tech products translates into higher economy-wide returns to innovation, leading to an increase in the aggregate level of private R&D. Using unique data on federal procurement in US states and performing panel fixed-effects estimations, we find support for the model's prediction of a positive R&D effect of the technological content of government procurement. Instrumental-variable estimations suggest a causal interpretation of our findings.

Parent Universities and the Location of Academic Startups

S. Heblich Viktor Slavtchev

in: Small Business Economics, No. 1, 2014

Abstract

Academic startups are thought to locate in their parent university’s home region because geographic proximity to a university facilitates access to academic knowledge and resources. In this paper we analyze the importance of a different channel, namely social ties between academic entrepreneurs and university researchers, for the access to academic knowledge and resources, and therefore for the location of the startups. We employ unique data on academic startups from regions with more than one university and find that only the parent university influences academic entrepreneurs’ decisions to stay in the region while other universities in the same region play no role. Our findings suggest that geographic proximity to a university may not per se guarantee access to knowledge and resources; social contacts are additionally required. The importance of social ties implies that academic knowledge and resources are not necessarily local public goods. This holds implications for universities’ role in stimulating regional development.

Proximity and the Transfer of Academic Knowledge: Evidence from the Spatial Pattern of Industry Collaborations of East German Professors

Viktor Slavtchev

in: Regional Studies, No. 5, 2013

Abstract

Proximity and the transfer of academic knowledge: evidence from the spatial pattern of industry collaborations of East German professors, Regional Studies. Universities can stimulate local economic development, particularly due to collaboration with local industry. Against this background, this study analyses when these interactions are local. Previous research suggests that university–industry linkages are mainly local because of tacit knowledge and the importance of physical proximity. This study provides additional evidence that the spatial pattern of university–industry linkages is a result of a complex matching process of appropriate partners. The results indicate that actors' individual and relational characteristics, institutional factors, and the particular type of knowledge play a role in collaboration. Hence, university–industry collaborations might not be local.

The Internationalization of Science and Its Influence on Academic Entrepreneurship

S. Krabel D. S. Siegel Viktor Slavtchev

in: Journal of Technology Transfer, No. 2, 2012

Abstract

We examine whether scientists employed in foreign countries and foreign-educated native researchers are more “entrepreneurial” than their “domestic” counterparts. We conjecture that foreign-born and foreign-educated scientists possess broader scientific skills and social capital, which increases their likelihood that they will start their own companies. To test this hypothesis we analyze comprehensive data from researchers at the Max Planck Society in Germany. Our findings provide strong support for the conjecture that academic entrepreneurship can be stimulated by facilitating the mobility of scientists across countries.

Determinants of the Efficiency of Regional Innovation Systems

Michael Fritsch Viktor Slavtchev

in: Regional Studies, No. 7, 2011

Abstract

Determinants of the efficiency of regional innovation systems, Regional Studies. This paper analyses differences in the efficiency of regional innovation systems. Alternative measures for the efficiency of regional innovation systems based on the concept of a knowledge production function are discussed. The empirical findings suggest that spillovers from within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector research and development. It is particularly the intensity of interactions between private and public sector research and development that increases the efficiency. It is found that regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

The Aggregate Effects of the Decline of Disruptive Innovation

Richard Bräuer

in: IWH Discussion Papers, No. 22, 2023

Abstract

This paper proposes a model that explains both recently documented facts about the decline of disruptive innovation and the decline in productivity growth as the result of large firms trying to monopolize technologies by poaching inventors from disruptive activities. To come to this conclusion, the paper builds an endogenous growth model with inventor labor markets on which firms can interact strategically. To inform this model, I perform an event study of the effect of disruptive inventions on their technology fields using PATSTAT (1980-2010). I document that technology classes without disruption slowly trend towards incrementalism and that after a disruption, more patents get registered and research becomes less incremental.

Minimum Wages, Productivity, and Reallocation

Mirja Hälbig Matthias Mertens Steffen Müller

in: IZA Discussion Paper, No. 16160, 2023

Abstract

We study the productivity effect of the German national minimum wage by applying administrative firm data. At the firm level, we confirm positive effects on wages and negative employment effects and document higher productivity even net of output price increases. We find higher wages but no employment effects at the level of aggregate industry × region cells. The minimum wage increased aggregate productivity in manufacturing. We do not find that employment reallocation across firms contributed to these aggregate productivity gains, nor do we find improvements in allocative efficiency. Instead, the productivity gains from the minimum wage result from within-firm productivity improvements only.

Do Larger Firms Exert More Market Power? Markups and Markdowns along the Size Distribution

Matthias Mertens Bernardo Mottironi

in: IWH Discussion Papers, No. 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.

Wirtschaftliche Folgen des Gaspreisanstiegs für die deutsche Industrie

Matthias Mertens Steffen Müller

in: Sachverständigenrat Wirtschaft, No. 4, 2022

Abstract

Diese Analyse nutzt amtliche Mikrodaten für die deutsche Industrie. Auf Ebene fein untergliederter Produkte werden der Verbrauch an Erdgas und der heimische Produktumsatz mit Daten der Vereinten Nationen zu Exporten und Importen verknüpft. Es zeigt sich, dass die 300 Produkte mit dem höchsten Gasverbrauch innerhalb der deutschen Industrie für knapp 90% des Gasverbrauchs der Industrie stehen, dass bei Gaspreiserhöhungen um das Vierfache gegenüber den Jahren 2015-2017 die Kosten für das durchschnittliche Produkt um 12 Cent pro Euro Umsatz steigen und dass ein Produktionsstopp der Produkte, die sowohl überdurchschnittlich gasintensiv sind als auch überdurchschnittlich leicht durch Importe substituiert werden können, 26% des Gesamtgasverbrauchs der Industrie einspart, aber weniger als 3% des Umsatzes der Industrie kostet.
