Abstract
Our primary goal is to analyse the drivers of evolutionary network change processes by using a stochastic actor-based simulation approach. We contribute to the literature by combining two unique datasets, concerning the German laser and automotive industry, between 2002 and 2006 to explore whether geographical, network-related, and techno-logical determinants affect the evolution of networks, and if so, as to what extent these determinants systematically differ for science-driven industries compared to scale-intensive industries. Our results provide empirical evidence for the explanatory power of network-related determinants in both industries. The ‘experience effect’ as well as the ‘transitivity effects’ are significant for both industries but more pronounced for laser manufacturing firms. When it comes to ‘geographical effects’ and ‘technological ef-fects’ the picture changes considerably. While geographical proximity plays an important role in the automotive industry, firms in the laser industry seem to be less dependent on geographical closeness to cooperation partners; instead they rather search out for cooperation opportunities in distance. This might reflect the strong dependence of firms in science-driven industries to access diverse external knowledge, which cannot necessarily be found in the close geographical surrounding. Technological proximity negatively influences cooperation decisions for laser source manufacturers, yet has no impact for automotive firms. In other words, technological heterogeneity seems to ex-plain, at least in science-driven industries, the attractiveness of potential cooperation partners.

Ten Years after Accession: State Aid in Eastern Europe

European State Aid Law Quarterly,
No. 2,
2014
Abstract
In the early phase of transition that started with the 1990s, Central and Eastern European Countries (CEEC) have pursued far-reaching vertical and individual industrial policy with a focus on privatisation and restructuring of traditional industries. Foreign investment from the West and the facilitation of the development of a market economy also involved massive injections of State support. With their accession to the European Union (EU), levels and forms of State aid came under critical review by the European Commission. Now that a first decade has passed since the first Eastern enlargement in 2004, this inquiry investigates how State aid policy in the CEECs has developed during the last...

Können altindustrielle Städte zu “Hot Spots“ der Kreativwirtschaft werden? Das Beispiel der Medienwirtschaft in Halle

Abstract
In den letzten Jahren wird die Kreativwirtschaft zunehmend als wichtiger Motor für die Entwicklung von Städten angesehen. Gerade in der Medienwirtschaft wird eine Zukunftsbranche für solche Städte gesehen, in denen traditionelle Branchen an Bedeutung verloren haben. So setzt auch die Stadt Halle seit einiger Zeit auf die Entwicklung der Medienwirtschaft. Es wird gezeigt, dass sich die Medienwirtschaft in der Stadt Halle in verschiedenen Teilbereichen gut entwickelt hat – obgleich die vorhandenen Standortfaktoren eigentlich nur bedingt für eine Ansiedlung von Medienfirmen in Halle sprechen und deshalb die Potentiale für die weitere Entwicklung begrenzt sein dürften.

Ein entscheidendes Jahr für die Banken

Abstract
Auf den europäischen Finanzmärkten ist eine gewisse Ruhe eingetreten. Seit die Europäische Zentralbank im vergangenen Jahr bekannt gegeben hat, den Zusammenhalt des Euroraums zu sichern, und seit Pläne zur Umsetzung einer Bankenunion Kontur gewonnen haben, sind Gefahren für die Finanzstabilität weniger prominent in den Schlagzeilen. Doch die Ruhe trügt.

The Ex Ante versus Ex Post Effect of Public Guarantees

Abstract
In October 2006, Dominion Bond Rating Service (DBRS) introduced new ratings for banks that account for the potential of government support. The rating changes are not a reflection of any changes in the respective banks’ credit fundamentals. We use this natural experiment to evaluate the consequences of bail out expectations for bank behavior using a difference in differences approach. The results suggest a striking difference between the effects of bail out probabilities during calm times (“ex ante”) versus during crisis times (“ex post”). During calm times, higher bail-out probabilities result in higher risk taking, consistent with the moral hazard view and much of the empirical literature. However, in crisis times, we find that banks with higher bail out probabilities tend to increase their risk taking less compared to banks that were ex ante unlikely to be bailed-out. Charter values are one part of the explanation: Supported banks may have a funding advantage relative to non-supported banks during the crisis. However, we cannot rule out that other factors also may be playing a role, including tighter supervision of supported banks in crisis times.

Changing Forces of Gravity: How the Crisis Affected International Banking
Claudia M. Buch, Katja Neugebauer, Christoph Schröder
IWH Discussion Papers,
No. 15,
2013
Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

IT Use, Productivity, and Market Power in Banking
Michael Koetter, Felix Noth
Journal of Financial Stability,
No. 4,
2013
Abstract
Information management is a core process in banking that can resolve information asymmetries and thereby help to mitigate competitive pressure. We test if the use of information technology (IT) contributes to bank output, and how IT-augmented bank productivity relates to differences in market power. Detailed bank-level information on the use of IT reveals a substantial upward bias in bank productivity estimates when ignoring banks’ IT expenditures. IT-augmented bank productivity correlates positively with Lerner markups. A mere increase in IT expenditures, however, reduces markups. Results hold across a range of bank output definitions and productivity estimation methods.

What Do We Learn from Schumpeterian Growth Theory?

Abstract
Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on four important aspects, namely: (i) the role of competition and market structure; (ii) firm dynamics; (iii) the relationship between growth and development with the notion of appropriate growth institutions; and (iv) the emergence and impact of long-term technological waves. In each case, Schumpeterian growth theory delivers predictions that distinguish it from other growth models and which can be tested using micro data.
