Regional Growth and Finance in Europe: Is there a Quality Effect of Bank Efficiency?
Iftekhar Hasan, Michael Koetter, Michael Wedow
Journal of Banking and Finance,
Nr. 8,
2009
Abstract
In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures of financial institutions. Contrary to the usual quantitative proxies of financial development, the quality of financial institutions is measured in this study as the relative ability of banks to intermediate funds. An improvement in bank efficiency spurs five times more regional growth then an identical increase in credit does. More credit provided by efficient banks exerts an independent growth effect in addition to direct quantity and quality channel effects.

Lending Technology, Bank Organization and Competition
Hans Degryse, Steven Ongena, Günseli Tümer-Alkan
Journal of Financial Transformation,
2009
Abstract
This paper reviews recent theoretical and empirical studies investigating how both bank technology and organization shape bank-borrower interactions. We refer to two related concepts for bank technology. First, the technologies banks employ in loan granting decisions and second, the advances in information technology linked to the bank's lending technology. We also summarize and interpret the theoretical and empirical work on bank organization and its influence on lending technologies. We show that the choice of lending technology and bank organization depend heavily on the availability of information, the technological progress in the collection of information, as well as the banking market structure and the legal environment. We draw important policy conclusions from the literature. Competition authorities and supervisors have to remain alert to the consequences of the introduction of any new technology because: (1) advances in technology do not necessarily lead to more intense banking competition, and (2) the impact of technological and financial innovation on financial efficiency and stability depends on the incentives of the entire „loan production chain.‟

Effects of Heterogeneity on Bank Efficiency Scores

European Journal of Operational Research,
Nr. 1,
2009
Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Marian Berneburg
Schriften des IWH,
Nr. 28,
2008
Abstract
Many situations in the history of the stock markets indicate that assets are not always efficiently priced. But why does it matter whether the stock market is efficiently priced? Because “well-functioning financial markets are a key factor to high economic growth”. (Mishkin and Eakins, 2006, pp. 3-4) In three essays, it is the aim of the author to shed some more light on the topic of market efficiency, which is far from being resolved. Since European equity markets have increased in importance globally, the author, instead of focusing on US markets, looks at a unified European equity market. By testing for a random walk in equity prices, revisiting Shiller’s claim of excess volatility through the means of a vector error correction model, and modifying the Gordon-Growth-Model, the book concludes that a small degree of inefficiency cannot be ruled out. While usually European equity markets are pricing assets correctly, some periods (e.g. the late 1990s and early 2000s) show clear signs of mispricing; the hypothesis of a world with two states (regime one, a normal efficient state, and regime two, a state in which markets are more momentum driven) presents a possible explanation.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
Nr. 58,
2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
Nr. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
Nr. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
Im Jahr 2003 wurde von der deutschen Kartellbehörde ein Zementkartell aufgedeckt. Eines der Hauptzentren des Kartells war Ostdeutschland, wo das ostdeutsche Zementkombinat Anfang der 1990er Jahre von der Treuhand im Rahmen der Privatisierung der ehemals volkseigenen Betriebe an vier große Zementproduzenten verkauft wurden.
In diesem Aufsatz stellen wir die Behauptung der Kartellbehörde in Frage, dass durch das Kartell Überschussgewinne auf dem ostdeutschen Markt erziehlt wurden. Wir behaupten, dass die juristischen Anzeichen eines Kartells nicht zwangsläufig den wirtschaftlichen Hinweisen entsprechen. Zu diesem Zweck versuchen wir nachzuweisen, dass die Zementnachfrage regional begrenzt ist und nur in einem sehr kleinen Umfang von der Produktpalette abhängt. Wenn das Zementkartell einen Einfluss auf die Wirtschaft hatte, dann müsste sich seine Zerschlagung in der Veränderung der individuellen Nachfragefunktion der Unternehmen widerspiegeln. Allerdings konnten mit dem verwendeten ökonometrischen Modell keine strukturellen Nachfrageänderungen beobachtet werden. Dies kann unter anderem damit begründet werden, dass Billigimporte aus Polen und der Tschechei sowie mittelständische Unternehmen dafür gesorgt haben, dass das Zementkartell seine Wirkung nie voll entfalten konnte.
Der Aufsatz zeigt, dass selbst in etablierten Marktwirtschaften wie Westdeutschland die Schwierigkeit besteht, Wettbewerb in bestimmten Industriebereichen zu generieren und dass hierfür die Offenheit der Wirtschaft entscheidend ist.
