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.

Bank Regulation and Supervision in Bank-dominated Financial Systems: A Comparison between Japan and Germany
Diemo Dietrich, Ralf Bebenroth, Uwe Vollmer
European Journal of Law and Economics,
2009
Abstract
This paper compares bank regulation and supervision in Japan and Germany. We consider these countries because they both have bank-dominated financial systems and their banking systems are often lumped together as one model, yet, bank stability differs significantly. We show that Japan and Germany have chosen different approaches to bank regulation and supervision and ask why they made their choices. We argue that bank regulation and supervision were less efficient in Japan than in Germany and that these differences were decisive for bank behavior.

The Ending of Solidarity Pact Payments: Are the “Neue Länder” Prepared Sufficiently?
Katja Wilde, Sabine Freye
Wirtschaft im Wandel,
No. 3,
2009
Abstract
Up to 2019, the “Neue Länder” in Germany are benefitting from financial transfer within the framework of the solidarity pact. From 2005 to 2007, the “Neue Länder” were able to improve they financial situation and used the solidarity pact payments efficiently. However, these payments are decreasing annually. This implies a significant financial reduction to the “Neue Länder’s” overall budgets and a considerable challenge for their future investments. This article analyses publications by the governments of the “Neue Länder” about their medium term budget planning and related progress reports from the year 2006. The consolidation of their budgets seems to be an essential aspect in the policy strategy of “Neue Länder” due to limited tax autonomy and legal restrictions on their expenditures. However, we identified several consolidation strategies with regard to infrastructural priorities, restructuring of administration, and creation of reserves. The public revenues of the “Neue Länder” are expected to decline in 2009 due to the current recession. In case that there are no fundamental changes in the underlying economic structures, the financial scope of the “Neue Länder” is going to be increasingly constrained, in particular with regard to future investments.

Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Marian Berneburg
Schriften des IWH,
No. 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.

Die volkswirtschaftliche Bedeutung von Private Equity
Ulrich Blum
Private Equity. Beurteilungs- und Bewertungsverfahren von Kapitalbeteiligungsgesellschaften,
2008
Abstract
Private equity is a very specific institutional way of providing private capital to enterprises. The contribution inquires why it increased its economic importance and public visibility over the last years. The role of private capital within the framework of the innovation theory, transaction cost theory and the risk theory is assessed. Private equity is a specific way of organizing the procurement with private capital for enterprises in risky markets in order to efficiently reducing transaction costs. More and above, it is important for credible market-entry strategies. As most markets are incomplete and because of tax regulations which cannot be considered to be efficient under present conditions, the economic role of private equity has increased. The increase economic role, but also importance in the firm, necessitates a steering of enterprises along value-oriented objectives. As the “hype” has decreased in summer 2007, the article ends with an assessment of future prospects.

Beseitigung struktureller Defizite mit der Gemeinschaftsaufgabe „Verbesserung der regionalen Wirtschaftsstruktur“ – Ein Vergleich der Strategien in den neuen Bundesländern
Mirko Titze
Raumforschung und Raumordnung,
2008
Abstract
The Joint Task “For the Improvement of the Regional Economic Structure” is one of the most important instruments for the “Reconstruction East”. Herein the federal states have an extensive flexibility to define their own kind of industrial policy. Due to their structural deficits this paper is focused on the federal states in East-Germany. A decrease in the budget constrains the governments to improve efficiency of subsidies. However, there is one way to solve this problem: change unselective government aid to regional as well as sectoral government aid. This paper shows that there is no federal state, which has applied this kind of policy forcefully.

Agenda 2010: Neues unter Deutschlands Himmel?
Ulrich Blum
Wirtschaftsdienst,
No. 3,
2008
Abstract
The paper analyzes to what extent the reform of the German social security and welfare system, known as the “Hartz-IV-Reforms” under the “Agenda 2010”, has been successful. It is shown that the integration of welfare and social security payments increased efficiency as did prior deregulations of the labor market. However, the implementation was partly inefficient due to a misalignment between crucial instruments and incentive structure of individuals. This led to unforeseen expenditures that partly continue until today. Due to this inefficiency, parts of the reform lost its political acceptance. Furthermore, the article shows that many of these reforms had already been prepared intellectually by selected think tanks in the 90ies. The reforms are consistent with a consensus among scholars regarding the ability of the modern state to protect citizens from individual life risks. Finally, the article discusses the future agenda with respect to other important economic policy instruments beyond the integration of welfare and social security such as incentive structure in the established taxation system.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 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,
No. 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.
