Financial Integration, Housing, and Economic Volatility

Abstract
The Great Recession illustrates the sensitivity of the economy to housing. This paper shows that financial integration, fostered by securitization and nationwide branching, amplified the positive effect of housing price shocks on the economy during the 1994–2006 period. We exploit variation in credit supply subsidies across local markets from government-sponsored enterprises to measure housing price changes unrelated to fundamentals. Using this instrument, we find that house price shocks spur economic growth. The effect is larger in localities more financially integrated, through both secondary loan market and bank branch networks. Financial integration thus raised the effect of collateral shocks on local economies, increasing economic volatility.

Isolation and Innovation – Two Contradictory Concepts? Explorative Findings from the German Laser Industry

IWH Discussion Papers,
No. 1,
2015
Abstract
We apply a network perspective and study the emergence of core-periphery (CP) structures in innovation networks to shed some light on the relationship between isolation and innovation. It has been frequently argued that a firm’s location in a densely interconnected network area improves its ability to access information and absorb technological knowledge. This, in turn, enables a firm to generate new products and services at a higher rate compared to less integrated competitors. However, the importance of peripheral positions for innovation processes is still a widely neglected issue in literature. Isolation may provide unique conditions that induce innovations which otherwise may never have been invented. Such innovations have the potential to lay the ground for a firm’s pathway towards the network core, where the industry’s established technological knowledge is assumed to be located.
The aim of our paper is twofold. Firstly, we propose a new CP indicator and apply it to analyze the emergence of CP patterns in the German laser industry. We employ publicly funded Research and Development (R&D) cooperation project data over a period of more than two decades. Secondly, we explore the paths on which firms move from isolated positions towards the core (and vice versa). Our exploratory results open up a number of new research questions at the intersection between geography, economics and network research.

Network Positioning, Co-Location or Both?

Innovation Networks in the German Laser Industry. Springer Cham,
2015
Abstract
Previous research indicates that firm innovativeness can either be determined by a firm’s position within the network dimension or by its position within the geographical dimension. Integrative studies addressing both distinct and combined proximity effects remains rare (cf. Whittington et al. 2009). Thus, we address in this Chapter the following research question: Are firm-level innovation outcomes positively or negatively related to network positioning effects, geographical co-location effects or combined proximity effects; and if the latter case is true, are the combined effects substitutional or complementary in nature? Panel data count models with fixed and random effects were used to analyze a firm’s innovative performance as measured by patent application counts. This last empirical analysis is organized as follows: We start with a short introduction in Sect. 12.1. Next, we provide a brief discussion of theoretical background in Sect. 12.2. In Sect. 12.3 we introduce our conceptual framework and derive our hypotheses. In Sect. 12.4 we introduce the data and methods used. Next, we outline the estimation strategy and report our empirical results in Sect. 12.5. Finally, we discuss our findings and conclude with a number of critical remarks in Sect. 12.6.

Do We Need New Modelling Approaches in Macroeconomics?

Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

The Structure and Evolution of Intersectoral Technological Complementarity in R&D in Germany from 1990 to 2011
Matthias Brachert, T. Broekel
Abstract
Technological complementarity is argued to be a crucial element for effective Research and Development (R&D) collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis.
The results illustrate sectors being complements both from a dyadic and portfolio/ network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

25 Years after the Fall of the Berlin Wall: The Economic Integration of East Germany
Einzelveröffentlichungen,
2014
Abstract
Citizens of the German Democratic Republic (GDR) regained their civil liberties when the Berlin Wall fell 25 years ago. Since then, they have been able to travel freely and have been free to choose where to live and work. The fall of the Berlin Wall was quickly followed by preparations for German Unification at a speed unparalleled in history: the first free Volkskammer elections on 18 March 1990, the economic, monetary and social union on 1 July 1990, and finally, the unification of Germany when the GDR was included in the jurisdiction of the Basic Law of the Federal Republic of Germany. The integration of the economies of East and West Germany, however, has proven to be a drawn-out process.

25 Jahre nach dem Mauerfall: Wirtschaftliche Integration Ostdeutschlands im Spiegel der Forschung am IWH
Einzelveröffentlichungen,
2014
Abstract
Als vor 25 Jahren die Berliner Mauer fiel, gewannen die Bürger der DDR ihre bürgerlichen Freiheiten zurück. Sie können seitdem frei reisen und ihren Wohn- und Arbeitsort frei wählen. Auf den Mauerfall folgten in historisch einmaligem Tempo Weichenstellungen zur Deutschen Einheit: erste freie Volkskammerwahlen am 18.03.1990, die Wirtschafts-, Währungs- und Sozialunion am 01.07.1990 und schließlich die Einheit Deutschlands durch den Beitritt der DDR zum Geltungsbereich des Grundgesetzes der Bundesrepublik Deutschland. Die Integration der ost- und westdeutschen Wirtschaft ist allerdings ein langwieriger Prozess.
