The Identification of Technology Regimes in Banking: Implications for the Market Power-Fragility Nexus
Michael Koetter, Tigran Poghosyan
Journal of Banking and Finance,
Nr. 8,
2009
Abstract
Neglecting the existence of different technologies in banking can contaminate efficiency, market power, and other performance measures. By simultaneously estimating (i) technology regimes conditional on exogenous factors, (ii) efficiency conditional on risk management, and (iii) Lerner indices of German banks, we identify three distinct technology regimes: Public & Retail, Small & Specialized, and Universal & Relationship. System estimation at the regional level reveals that greater bank market power increases bank profitability but also fosters corporate defaults. Corporate defaults, in turn, lead to higher probabilities of bank distress, which supports the market power-fragility hypothesis.

Stages of the 2007/2008 Global Financial Crisis: Is there a Wandering Asset Price Bubble?
Lucjan T. Orlowski
Economics E-Journal 43. Munich Personal RePEc Archive 2008,

Abstract
This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk effects on other financial institutions; the commodity price bubble, and the ultimate demise of investment banking in the U.S. The study argues that the severity of the crisis is influenced strongly by changeable allocations of global savings coupled with excessive credit creation, which lead to over-pricing of varied types of assets. The study calls such process a “wandering asset-price bubble“. Unstable allocations elevate market, credit, and liquidity risks. Monetary policy responses aimed at stabilizing financial markets are proposed.

Contestability, Technology and Banking

Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

Growth, Volatility, and Credit Market Imperfections: Evidence from German Firms
Claudia M. Buch, Jörg Döpke
Journal of Economic Studies,
2008
Abstract
Purpose – The purpose of this paper is two-fold. First, it studies whether output volatility and growth are linked at the firm-level, using data for German firms. Second, it explores whether the link between volatility and growth depends on the degree of credit market imperfections.
Design/methodology/approach – The authors use a novel firm-level dataset provided by the Deutsche Bundesbank, the so-called Financial Statements Data Pool. The dataset has time series observations for German firms for the period 1997-2004, and the authors use information on the debt-to-assets or leverage ratio of firms to proxy for credit-constraints at the firm-level. As additional proxies for the importance of credit market imperfections, we use information on the size and on the legal status of firms.
Findings – The authors find that higher volatility has a negative impact on growth for small and a positive impact for larger firms. Higher leverage is associated with higher growth. At the same time, there is heterogeneity in the determinants of growth across firms from different sectors and across firms with a different legal status.
Practical implications – While most traditional macroeconomic models assume that growth and volatility are uncorrelated, a number of microeconomic models suggest that the two may be linked. However, it is unclear whether the link is positive or negative. The paper presents additional evidence regarding this question. Moreover, understanding whether credit market conditions affect the link between volatility and growth is of importance for policy makers since it suggests a channel through which the credit market can have long-run welfare implications. The results stress the importance of firm-level heterogeneity for the effects and effectiveness of economic policy measures.
Originality/value – The paper has two main novel features. First, it uses a novel firm-level dataset to analyze the determinants of firm-level growth. Second, it analyzes the growth-volatility nexus using firm-level data. To the best of the authors' knowledge, this is the first paper, which addresses the link between volatility, growth, and credit market imperfections using firm-level data.

Foreign Subsidiaries in the East German Innovation System – Evidence from manufacturing industries
Jutta Günther, Johannes Stephan, Björn Jindra
Applied Economics Quarterly Supplement,
Nr. 59,
2008
Abstract
Die Veröffentlichung analysiert das Ausmaß technologischer Leistungsfähigkeit auf ausländische Tochtergesellschaften, welche in Ostdeutschland angesiedelt sind. Darüber hinaus betrachtet es Determinanten des technologischen Beschaffungsverhaltens ausländischer Tochtergesellschaften. Die Theorie der internationalen Produktion unterstreicht die Wichtigkeit von Variablen auf der strategischen und regionalen Ebene. Dennoch lassen existierende empirische Studien im Großen und Ganzen Faktoren auf regionaler Ebene aus. Wir entnehmen die Studienergebnisse aus der „ADI Mikrodatenbank“ des IWH, welche erst seit kurzem zur Verfügung steht, um die Analyse durchzuführen. Wir fanden heraus, dass ausländische Tochtergesellschaften im Vergleich zum gesamten verarbeitenden Gewerbe in Ostdeutschland überdurchschnittlich technologisch aktiv sind. Dies kann teilweise durch die industrielle Struktur der ausländischen Direktinvestitionen erklärt werden. Dennoch bezieht nur ein begrenzter Teil ausländischer Tochtergesellschaften mit F&E und/oder Innovationsaktivitäten technologisches Wissen aus dem ostdeutschen Innovationssystem. Wenn eine Tochtergesellschaft die Strategie der Kompetenzvermehrung verfolgt oder lokalen Handel betreibt, dann bezieht sie eher technologisches Wissen lokal. Die Ausstattung einer Region mit Humankapital und wissenschaftlicher Infrastruktur hat ebenfalls einen positiven Effekt. Diese Ergebnisse lassen schlussfolgern, dass ausländische Tochtergesellschaften in Ostdeutschland nur teilweise mit dem regionalen Innovationssystem verbunden sind. Strategien werden diskutiert.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
Nr. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

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.

Slippery Slopes of Stress: Ordered Failure Events in German Banking
Thomas Kick, Michael Koetter
Journal of Financial Stability,
Nr. 2,
2007
Abstract
Outright bank failures without prior indication of financial instability are very rare. In fact, banks can be regarded as troubled to varying degrees before outright closure. But failure studies usually neglect the ordinal nature of bank distress. We distinguish four different kinds of increasingly severe events on the basis of the distress database of the Deutsche Bundesbank. Only the worst distress event entails a bank to exit the market. Since the four categories of hazard functions are not proportional, we specify a generalized ordered logit model to estimate respective probabilities of distress simultaneously. We find that the likelihood of ordered distress events changes differently in response to given changes in the financial profiles of banks. Consequently, bank failure studies should account more explicitly for the different shades of distress. This allows an assessment of the relative importance of financial profile components for different degrees of bank distress.

FDI versus exports: Evidence from German banks
Claudia M. Buch, A. Lipponer
Journal of Banking and Finance,
Nr. 3,
2007
Abstract
We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.
