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.

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, Nr. 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, Nr. 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, Nr. 5, 2013

Abstract

Nähe und Übertragung von akademischem Wissen: Belege aus dem räumlichen Muster der Kooperation zwischen ostdeutschen Professoren und der Industrie, Regional Studies. Universitäten können die ökonomische Entwicklung von Regionen stimulieren, insbesondere durch Kooperation mit der lokalen Industrie. Die vorliegende Studie analysiert, wann solche Kooperationen lokal stattfinden. Die existierende Literatur deutet daraufhin, dass aufgrund von tacidem Wissen und der Bedeutung geographischer Nähe Kooperationen überwiegend lokal stattfinden. Die vorliegende Studie findet Evidenz, dass das räumliche Muster von Kooperationen zwischen Universitäten und der Industrie als Resultat eines komplexen Matching-Prozesses zwischen Partnern mit geeigneten Charakteristika betrachtet werden kann. Die Ergebnisse deuten darauf hin, dass individuelle, relationale sowie institutionelle Charakteristika der Akteure eine wichtige Rolle für die Partnerwahl spielen. Demnach sind lokale Kooperationen nicht zwingend.

The Internationalization of Science and Its Influence on Academic Entrepreneurship

S. Krabel D. S. Siegel Viktor Slavtchev

in: Journal of Technology Transfer, Nr. 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, Nr. 7, 2011

Abstract

Determinanten der technischen Effizienz von regionalen Innovationssystemen, Regional Studies. Wir analysieren Unterschiede in der Effizienz regionaler Innovationssysteme (RIS). Zunächst werden alternative Maße für die Effizienz von RIS diskutiert, die auf dem Konzept der Wissensproduktionsfunktion aufbauen. Die empirischen Ergebnisse deuten darauf hin, dass sowohl Spillover aus dem privaten Sektor als auch von Hochschulen und anderen öffentlichen Forschungseinrichtungen die Effizienz privater F&E-Aktivitäten positiv beeinflussen. Insbesondere die Intensität der Interaktion zwischen öffentlichen Einrichtungen und dem Privatsektor führt zu hoher Effizienz. Regionen, die durch Großbetriebe dominiert sind, weisen tendenziell eine geringere Effizienz der Innovationsaktivitäten auf als Regionen mit einer geringeren durchschnittlichen Betriebsgröße.

Wirtschaftliche Folgen des Gaspreisanstiegs für die deutsche Industrie

Matthias Mertens Steffen Müller

in: Sachverständigenrat Wirtschaft, Nr. 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.

Offshoring, Domestic Employment and Production. Evidence from the German International Sourcing Survey

Wolfhard Kaus Markus Zimmermann

in: IWH Discussion Papers, Nr. 14, 2022

Abstract

This paper analyses the effect of offshoring (i.e., the relocation of activities previously performed in-house to foreign countries) on various firm outcomes (domestic employment, production, and productivity). It uses data from the International Sourcing Survey (ISS) 2017 for Germany, linked to other firm level data such as business register and ITGS data. First, we find that offshoring is a rare event: In the sample of firms with 50 or more persons employed, only about 3% of manufacturing firms and 1% of business service firms have performed offshoring in the period 2014-2016. Second, difference-in-differences propensity score matching estimates reveal a negative effect of offshoring on domestic employment and production. Most of this negative effect is not because the offshoring firms shrink, but rather because they don’t grow as fast as the non-offshoring firms. We further decompose the underlying employment dynamics by using direct survey evidence on how many jobs the firms destroyed/created due to offshoring. Moreover, we do not find an effect on labour productivity, since the negative effect on domestic employment and production are more or less of the same size. Third, the German data confirm previous findings for Denmark that offshoring is associated with an increase in the share of ‘produced goods imports’, i.e. offshoring firms increase their imports for the same goods they continue to produce domestically. In contrast, it is not the case that offshoring firms increase the share of intermediate goods imports (a commonly used proxy for offshoring), as defined by the BEC Rev. 5 classification.

The Financial Channel of Wage Rigidity

Benjamin Schoefer

in: Econometrics Laboratory (EML), April 2022

Abstract

I propose a financial channel of wage rigidity. In recessions, rigid average wages squeeze cash flows, forcing firms to cut hiring due to financial constraints. Indeed, empirical cash flows and profits would turn acyclical if wages were only moderately more procyclical. I study this channel in a search and matching model with financial constraints and wage rigidity among incumbent workers (but flexible new hires’ wages). While neither feature generates amplification individually, their interaction can account for much of the empirical labor market fluctuations—breaking the neutrality of incumbents’ wages for hiring, and showing that financial amplification of business cycles requires wage rigidity.

Intangible Capital and Productivity. Firm-level Evidence from German Manufacturing

Wolfhard Kaus Viktor Slavtchev Markus Zimmermann

in: IWH Discussion Papers, Nr. 1, 2020

Abstract

We study the importance of intangible capital (R&D, software, patents) for the measurement of productivity using firm-level panel data from German manufacturing. We first document a number of facts on the evolution of intangible investment over time, and its distribution across firms. Aggregate intangible investment increased over time. However, the distribution of intangible investment, even more so than that of physical investment, is heavily right-skewed, with many firms investing nothing or little, and a few firms having very large intensities. Intangible investment is also lumpy. Firms that invest more intensively in intangibles (per capita or as sales share) also tend to be more productive. In a second step, we estimate production functions with and without intangible capital using recent control function approaches to account for the simultaneity of input choice and unobserved productivity shocks. We find a positive output elasticity for research and development (R&D) and, to a lesser extent, software and patent investment. Moreover, the production function estimates show substantial heterogeneity in the output elasticities across industries and firms. While intangible capital has small effects for firms with low intangible intensity, there are strong positive effects for high-intensity firms. Finally, including intangibles in a gross output production function reduces productivity dispersion (measured by the 90-10 decile range) on average by 3%, in some industries as much as nearly 9%.

TV and Entrepreneurship

Viktor Slavtchev Michael Wyrwich

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.
