Abstract
Most research on R&D internationalisation focuses on comparative analysis of location factors at the national level of analysis. Very little work, however, has taken place in this field for the sub-national regional location behavior of multi-national enterprises (MNE). The paper contributes to the existing research by providing evidence on the determinants of foreign technological activities at the sub-national level for Germany, which hosts the largest share of foreign R&D within the EU27 and features the highest cross-regional dispersion of patented research. Using a pooled count data model, we estimate the effect of various sources for externalities on the extent of foreign technological activity across regions. Particular attention is paid to the role of local knowledge spillovers, technological specialization and diversification. We differentiate foreign and domestic sources of specialisation and account for region and sector-specific influences. This is the first time that the ‘cross-border-ownership’ principle to measure R&D internationalisation is combined with regionalised patent information.
To verify our findings we develop hypotheses. In particular, we expect and find that foreign technological activity is attracted by technologically specialised sectors of regions. In contrast to current empirical work, this effect applies both to foreign as well as domestic sources of specialization, although effects on foreign specialization seem more significant. We expect and find the same for science-industry spillovers. We postulate a negative impact of domestic specialization on foreign technological activities and a strong positive effect from diversificationspillovers, by comparison with specialisation spillovers, but these hypotheses are rejected. We find that the direction of the specialisation effect depends on dominance in the position of domestic firms as well as on the balance of knowledge flows between them and foreign actors.

Determinants of Foreign Technological Activity in German Regions – A Count Model Analysis of Transnational Patents (1996-2009)
Eva Dettmann, Iciar Dominguez Lacasa, Jutta Günther, Björn Jindra
Abstract
This paper analyses the determinants of spatial distribution of foreign technological activity across 96 German regions (1996-2009). We identify foreign inventive activity by applying the ‘cross-border-ownership concept’ to transnational patent applications. The descriptive analysis shows that foreign technological activity more than doubled during the observation period with persistent spatial heterogeneity in Germany. Using a pooled count data model, we estimate the effect of various sources for externalities on the extent of foreign technological activity across regions. Our results show that foreign technological activity is attracted by technologically specialised sectors of regions. In contrast to existing findings this effect applies both to foreign as well as domestic sources of specialisation. We show that the relation between specialisation and foreign technological activity is non-linear and that it is influenced by sectoral heterogeneity. Externalities related to technological diversification attract foreign R&D only into ‘higher order’ regions.

Specialization versus Diversification: Perceived Benefits of Different Incubation Models
Michael Schwartz, Christoph Hornych
International Journal of Entrepreneurship and Innovation Management,
No. 3,
2012
Abstract
Business incubator initiatives are a widespread policy instrument for the promotion of entrepreneurship, innovation and the development of new technology-based firms. Recently, there has been an increasing tendency for the more traditional diversified incubators to be superseded by incubators focusing their support elements, processes and selection criteria on firms from one specific sector, and its particular needs. Despite the increasing importance of such specialized incubators in regional innovation strategies, the question of whether they are advantageous has neither been investigated empirically nor discussed theoretically in detail. Drawing on large-scale survey data from 161 firms incubated in either diversified or specialized incubators in Germany, we investigate the benefits to firms of being part of a specialized business incubator as opposed to being part of a generalized business incubator. The investigation of the value-added contribution of specialized incubators, in particular regarding hardware components, business assistance, networking and reputation gains, reveals considerable differences compared to the more diversified incubation model.

Local Economic Structure and Sectoral Employment Growth in German Cities
Annette Illy, Michael Schwartz, Christoph Hornych, Martin T. W. Rosenfeld
Tijdschrift voor economische en sociale geografie,
No. 5,
2011
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on sectoral employment growth in German cities (“urban growth”). We test four elements simultaneously – sectoral specialisation, diversification of economic activities, urban size and the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. Our regression results show a U-shaped relationship between localisation economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former, a U-shaped relationship is found, whereas the effect is inversely U-shaped for the latter.

Informed and Uninformed Investment in Housing: The Downside of Diversification
Elena Loutskina, Philip E. Strahan
Review of Financial Studies,
No. 5,
2011
Abstract
Mortgage lenders that concentrate in a few markets invest more in information collection than diversified lenders. Concentrated lenders focus on the information-intensive jumbo market and on high-risk borrowers. They are better positioned to price risks and, thus, ration credit less. Adverse selection, however, leads to higher retention of mortgages relative to diversified lenders. Finally, concentrated lenders have higher profits than diversified lenders, their profits vary less systematically, and their stock prices fell less during the 2007—2008 credit crisis. The results imply that geographic diversification led to a decline in screening by lenders, which likely played a role in the 2007–2008 crisis.

Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.

Cross-border Diversification in Bank Asset Portfolios
Claudia M. Buch, J.C. Driscoll, C. Ostergaard
International Finance,
forthcoming
Abstract
We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean–variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in banks' portfolios: countries whose residents score higher on a survey measure of trust are more likely to be overweighted, while countries that have tighter capital controls are less likely to be overweighted. From a policy standpoint, the importance of culture suggests a limit to the degree of financial integration that may be achievable by the removal of formal economic barriers.

Urban Growth in Germany – The Impact of Localization and Urbanization Economies
Christoph Hornych, Michael Schwartz, Annette Illy, Martin T. W. Rosenfeld
IWH Discussion Papers,
No. 19,
2009
Abstract
This study examines the impact of localization and urbanization economies as well as the impact of city size on urban growth in German cities from 2003 to 2007. Although, from a theoretical perspective, agglomeration economies are supposed to have positive impacts on regional growth, prior empirical studies do not show consistent results. Especially little is known about agglomeration economies in Germany, where interregional support policy and the characteristics of the federal system are further determinants of urban growth. The results of the econometric analysis show a U-shaped relationship between specialization and urban growth, which particularly holds for manufacturing industries. We do not find evidence for the impact of Jacobs-externalities; however, city size shows a positive (but decreasing) effect on urban growth.

Determinants of Academic-Industry Linkages and Incubator-internal Cooperation Patterns of Incubator Firms: Empirical Evidence from Germany
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 2,
2009
Abstract
Der Beitrag untersucht, inwieweit es durch eine Förderung mittels Technologie- und Gründerzentren (TGZ) gelingt, Unternehmen beim Aufbau von Kooperationsbeziehungen zu unterstützen. Im Rahmen einer Querschnittsuntersuchung wird sowohl die Vernetzung der Unternehmen innerhalb der Zentren als auch die Initiierung von Kontakten zu Wissenschafts- und Forschungseinrichtungen untersucht. Erstmalig wird dabei den vermuteten Unterschieden zwischen spezialisierten und diversifizierten Zentrenkonzepten nachgegangen. Entgegen der vorherrschenden Meinung in der Literatur zeigen die empirischen Ergebnisse, dass sich bei Mietern in spezialisierten TGZ, trotz größerer Überschneidungen, keine intensiveren Netzwerkbeziehungen entwickeln als in diversifizierten Zentren. Signifikante Vorteile einer Spezialisierung von TGZ können hingegen bei der Wissenschaftsanbindung der Mieterunternehmen nachgewiesen werden, wobei nur jedes zweite Unternehmen in diversifizierten TGZ Kontakte mit Wissenschafts- und Forschungseinrichtungen unterhält.

A Lesson Learned? Pre- and Post-Crisis Entry Decisions in Turkish Banking
H. Evren Damar
Contemporary Economic Policy,
No. 1,
2009
Abstract
This study looks at the determinants of entry by Turkish banks into local markets during the periods before and after the crisis of 2000–2001. Motivated by a theoretical model of entry, results of fixed-effects logit regressions suggest that there has been a change in the geographical diversification strategies of Turkish banks. It appears that the dominance of strategic concerns, such as competing with banks of similar size, has diminished, while economic concerns, such as incumbent characteristics and cost considerations, have become more important. Overall, the postcrisis restructuring policies seem to have led to improved decision making in the sector.
