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.

International Banking and the Allocation of Risk
Claudia M. Buch
IAW Discussion Paper No. 32,
2007
Abstract
Macroeconomic risks could magnify individual bank risk. Mitigating the influence of economy-wide risks on banks could therefore be very important to maintain a smooth-running banking system. In this paper, we explore the extent to which macroeconomic risks affect banks. We use a bank-level dataset on over 2,000 banks worldwide for the years 1995-2002 to study the effect of macroeconomic volatility, the openness of the banking system, and banking regulations on bank risks. Our measure of bank risk is the volatility of banks' pre-tax profits. We find that macroeconomic volatility increases banks' profit volatility and that international openness of the banking system lowers bank risk. We find no impact of banking regulation on profit volatility. Our findings suggest that if policymakers want to lower bank risk, they should seek to lower macroeconomic volatility as well as increase openness in the banking system.

FDI versus exports: Evidence from German banks
Claudia M. Buch, A. Lipponer
Journal of Banking and Finance,
No. 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.

Local Public Utilities' Profits and Municipal Expenses in Germany: An Empirical Analysis
Peter Haug, Birger Nerré
Proceedings of the 99th Annual Conference on Taxation (November 16-18), Washington DC,
2006
Abstract
The article offers information on profits and municipal expenses of local public utilities in Germany. It reveals that cities and municipalities faced rising expenses over the last years and the only way for local governments to avoid budgetary bottlenecks is to postpone infrastructure investment and increase short-term borrowing. The countries municipalities tried to overcome such difficulties by increasing local public utilities' profits.

Under which conditions do inland suppliers profit from foreign direct investment?

Abstract
Aus theoretischer Sicht ergeben sich durch die Präsenz ausländischer Unternehmen nicht nur realwirtschaftliche Effekte auf Produktion und Beschäftigung, sondern auch ein Potential für technologische Entwicklung durch Wissenstransfer zu einheimischen Unternehmen. Dieser Wissenstransfer ist abhängig von dem Grad der Verflechtung des ausländischen Unternehmens mit der einheimischen Wirtschaft. Dabei kommt der Beziehung zwischen Investor und einheimischen Zulieferunternehmen eine zentrale Bedeutung zu, denn multinationale Unternehmen haben ein strategisches Interesse, alle lokalen Effizienzvorteile auszuschöpfen. Der vorliegende Beitrag unterstellt, daß sowohl die Ausbildung von Zulieferbeziehungen als auch das Potential für Wissenstransfer zum einen von organisatorischen Faktoren im ausländischen Unternehmen und zum anderen von der lokalen Wissensbasis und der technologischen Leistungsfähigkeit abhängig sind. Dieser Zusammenhang wird an Hand eines Datensatzes von 434 Tochterunternehmen aus fünf Mittel- und Osteuropäischen Ländern getestet. Die Ergebnisse zeigen, daß die Intensität von Zulieferbeziehungen als auch das Potential für Wissenstransfer steigt, wenn Tochterunternehmen als Joint Venture geführt werden sowie Eigenverantwortung in den Bereichen Logistik und Zulieferung besitzen. Die technologische Leistungsfähigkeit des heimischen Sektors fördert sowohl die Intensität von Zulieferbeziehungen als auch das Potential für Wissenstransfer. Zusätzlich steigert die absorptive Kapazität der einheimischen Zulieferbetriebe das Potential für Wissenstransfer. Will man verhindern, daß ausländische Investitionen auf einer „Insel“ inmitten der einheimischen Wirtschaft operieren und keine Wissenseffekte generieren, dann bietet die Förderung von Forschungs- und Entwicklungskooperationen zwischen ausländischen Investoren und lokalen Zulieferbetrieben in technologisch leistungsfähigen Sektoren ein opportunes Mittel.

Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
No. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.

Entry and Strategic Information Display in Credit Markets
Jan Bouckaert, Hans Degryse
Economic Journal,
No. 513,
2006
Abstract
In many countries, lenders voluntarily provide information about their borrowers to private credit registries. A recent World Bank survey reveals that the display of a lender's own borrower information is often not reciprocated. That is, access to these registries does not require the prior provision of proprietary data. We argue that incumbent lenders release information about a portion of their profitable borrowers for strategic reasons. The reasoning is that the pool of unreleased borrowers becomes characterised by a severe adverse selection problem. This prevents the entrants from bidding for all the incumbent's profitable borrowers and reduces their scale of entry.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
No. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
No. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

IWH construction survey East Germany at the beginning of 2006: slightly more stable profitability, expectations less pessimistic

Abstract
Aufgrund von Sonderfaktoren, wie Vorzieheffekte infolge der Kürzung der Eigenheimzulage, Restmaßnahmen zur Beseitigung der Flutschäden und einzelne Großprojekte, wurde die bis 2002 beobachtete steile Abwärtsbewegung der Baunachfrage auch im Jahr 2005 abgebremst. Die Rückgänge waren sowohl im Wohnungsbau als auch im Nichtwohnbau mit etwa 6% nahezu so hoch wie im Jahr zuvor. Laut Umfrage des IWH im Dezember 2005 hat diese Entwicklung zu einer Stabilisierung der Ertragslage im Baugewerbe geführt. Die Bauunternehmen verharren in weit geringerem Maße als im Jahr zuvor in der Verlustzone. Zugleich ist die Fluktuation innerhalb der Gruppe der Gewinnunternehmen geringer geworden. Für das laufende Jahr 2006 bleiben die befragten Unternehmen zwar in der überwiegenden Mehrheit skeptisch, die erwarteten Einbußen fallen aber mit etwa 2½ Prozent geringer aus als im Jahr zuvor.
