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

Ostdeutscher Produktivitätsrückstand und Betriebsgröße
Steffen Müller, Georg Neuschäffer
Wirtschaft im Wandel,
Nr. 3,
2019
Abstract
Auch 30 Jahre nach dem Mauerfall ist die Produktivität der ostdeutschen Wirtschaft um 20% geringer als die der westdeutschen. Vielfach wird dies dadurch erklärt, dass westdeutsche Betriebe größer sind – denn größere Betriebe sind meist produktiver. Berechnungen auf Basis einzelbetrieblicher Daten bringen jedoch zum Vorschein, dass die Produktivitätslücke sich selbst dann nicht schließt, wenn Betriebe ähnlicher Größe verglichen werden, die zudem noch der gleichen Branche angehören und Ähnlichkeiten in weiteren für die Produktivität relevanten Merkmalen wie der Kapitalintensität, der Exporttätigkeit und dem Anteil qualifizierten Personals aufweisen.

The Value of Smarter Teachers: International Evidence on Teacher Cognitive Skills and Student Performance
Eric A. Hanushek, Marc Piopiunik, Simon Wiederhold
Journal of Human Resources,
Nr. 4,
2019
Abstract
We construct country-level measures of teacher cognitive skills using unique assessment data for 31 countries. We find substantial differences in teacher cognitive skills across countries that are strongly related to student performance. Results are supported by fixed-effects estimation exploiting within-country between-subject variation in teacher skills. A series of robustness and placebo tests indicate a systematic influence of teacher skills as distinct from overall differences among countries in the level of cognitive skills. Moreover, observed country variations in teacher cognitive skills are significantly related to differences in women’s access to high-skill occupations outside teaching and to salary premiums for teachers.

TV and Entrepreneurship
Viktor Slavtchev, Michael Wyrwich
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.

Persönliche Beziehungen, der Transfer von akademischem Wissen und der Standort von Gründungen aus Hochschulen
S. Heblich, Viktor Slavtchev
Wirtschaft im Wandel,
Nr. 6,
2015
Abstract
In dieser Studie wird die Bedeutung von persönlichen Beziehungen zwischen Unternehmensgründern aus Hochschulen und Hochschulforschern für die Entscheidung der Gründer, sich in der Region der Heimathochschule niederzulassen, untersucht. Am Beispiel von Gründungen aus Hochschulen in Regionen mit mehreren Hochschulen kann gezeigt werden, dass bei der Entscheidung der Gründer, in der Region zu bleiben, der Nähe zur Heimatfakultät größere Bedeutung zukommt als der Nähe zu vergleichbaren Fakultäten an anderen lokalen Hochschulen. Die Ergebnisse deuten darauf hin, dass für den Zugang zu akademischem Wissen und Ressourcen und deren Transfer in Privatunternehmen über das einfache lokale Vorhandensein von Hochschulen hinaus persönliche Beziehungen bedeutsam sind. Dies hat Implikationen für die Rolle der Hochschulen als Standortvorteil für Unternehmen, die von akademischem Wissen und Ressourcen profitieren können oder darauf angewiesen sind.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
L. Cycon, Michael Koetter
IWH Discussion Papers,
Nr. 9,
2015
Abstract
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.

Lessons from Schumpeterian Growth Theory
Philippe Aghion, Ufuk Akcigit, Peter Howitt
American Economic Review,
Nr. 5,
2015
Abstract
By operationalizing the notion of creative destruction, Schumpeterian growth theory generates distinctive predictions on important microeconomic aspects of the growth process (competition, firm dynamics, firm size distribution, cross-firm and cross-sector reallocation) which can be confronted using rich micro data. In this process the theory helps reconcile growth with industrial organization and development economics.

Im Fokus: Sächsische Kooperationsstrukturen im 7. Forschungsrahmenprogramm der Europäischen Union
Mirko Titze
Wirtschaft im Wandel,
Nr. 6,
2014
Abstract
Im Bereich Forschung und Entwicklung (FuE) bieten zwischenbetriebliche Kooperationen die Möglichkeit, Spezialisierungsvorteile zu nutzen und Wissen auszutauschen. Für die Entstehung von Innovationen ist insbesondere personengebundenes Wissen wichtig, dessen Ausbreitung jedoch räumlich begrenzt ist. Für die Innovationsdynamik einer Region sind deswegen neben überregionalen Beziehungen auch regionale Kooperationen bedeutsam. Der vorliegende Beitrag analysiert die Kooperationsstrukturen innerhalb geförderter Verbundprojekte des 7. Forschungsrahmenprogramms der Europäischen Union (EU) für den Zeitraum von 2007 bis 2013. Die Untersuchung richtet sich auf den Freistaat Sachsen. Der Beitrag knüpft an eine Untersuchung aus dem Jahr 2013 an, die zeigte, dass sächsische Akteure in einer bestimmten Art von Förderprogrammen, den Bundesprogrammen, heute vergleichsweise viele Kooperationspartner in räumlicher Nähe wählen. Es zeigt sich, dass es formelle Kooperationen zwischen sächsischen Akteuren auch innerhalb der internationalen Konsortien der Forschungsrahmenprogramme der EU gibt. Damit ist der Grundstein für den Austausch von personengebundenem Wissen gelegt. Aus internationaler Perspektive waren in den angesprochenen Projekten vorwiegend Partner aus Westeuropa beteiligt.

Parent Universities and the Location of Academic Startups
S. Heblich, Viktor Slavtchev
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.
