Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

The Quantity Theory Revisited: A New Structural Approach
Makram El-Shagi, Sebastian Giesen
Macroeconomic Dynamics,
No. 1,
2015
Abstract
We propose a unified identification scheme to identify monetary shocks and track their propagation through the economy. We combine three approaches dealing with the consequences of monetary shocks. First, we adjust a state space version of the P-star type model employing money overhang as the driving force of inflation. Second, we identify the contemporaneous impact of monetary policy shocks by applying a sign restriction identification scheme to the reduced form given by the state space signal equations. Third, to ensure that our results are not distorted by the measurement error exhibited by the official monetary data, we employ the Divisia M4 monetary aggregate provided by the Center for Financial Stability. Our approach overcomes one of the major difficulties of previous models by using a data-driven identification of equilibrium velocity. Thus, we are able to show that a P-star model can fit U.S. data and money did indeed matter in the United States.

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.

Interrelationship between Industrial and Innovation Development in East Germany

Region: Ekonomika i Soziologija,
No. 2,
2015
Abstract
The article demonstrates that the most important reason for the slowdown and stagnation of economic convergence in East Germany is the weakness in terms of research and development and innovation. It analyzes the interrelationship between industrial and innovative development in the East German federal states since 1990. The article shows how the East German industry sector and its R&D activities looked like in the late 1980s and which transition it had undergone in the course of privatization. The industrial development of the new federal states after 1990 is analyzed. The paper reveals structural shortcomings in East Germany's economy and considers their impact on the progress in R&D.

Drivers of the Spatial Emergence and Clustering of the Photovoltaic Industry in Germany

No. 3,

Abstract
The drivers of the spatial emergence and clustering of the photovoltaic industry in Germany. Following the relatedness literature, we explore to what extent related industries influenced the regional emergence of the photovoltaic (PV) industry. In addition, we shed light on factors explaining selective processes of clustering. We particularly argue that generic resources and resources of related activities have been crucial for the regional concentration in early phases of the industry life cycle. With increasing maturity, industry-specific resources became more important. Based on a unique dataset containing population dynamics of the German PV industry, the hypotheses are tested empirically. Our results partially confirm the assumed beneficial effects of related industries for the emergence of the PV industry. Moreover, we observe changes in the relative importance of factors supporting regional concentration, with industry-specific resources becoming dominant as the industry matures.

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.

Im Fokus: Sächsische Kooperationsstrukturen im 7. Forschungsrahmenprogramm der Europäischen Union
Mirko Titze
Wirtschaft im Wandel,
No. 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.

The Dynamics of Bank Spreads and Financial Structure
Reint E. Gropp, Christoffer Kok, J.-D. Lichtenberger
Quarterly Journal of Finance,
No. 4,
2014
Abstract
This paper investigates the effect of within banking sector competition and competition from financial markets on the dynamics of the transmission from monetary policy rates to retail bank interest rates in the euro area. We use a new dataset that permits analysis for disaggregated bank products. Using a difference-in-difference approach, we test whether development of financial markets and financial innovation speed up the pass through. We find that more developed markets for equity and corporate bonds result in a faster pass-through for those retail bank products directly competing with these markets. More developed markets for securitized assets and for interest rate derivatives also speed up the transmission. Further, we find relatively strong effects of competition within the banking sector across two different measures of competition. Overall, the evidence supports the idea that developed financial markets and competitive banking systems increase the effectiveness of monetary policy.
