    Access Pricing and Network Expansion in Natural Gas Markets

    Wir diskutieren alternative Ansätze zur Bekämpfung lokaler Marktmacht in Erdgasmärkten mit einem besonderen Fokus auf den Ausbau bestehender Pipelinekapazitäten. Cremer und Laffont (Eur. Econ. Rev. 46:928-935, 2002) haben gezeigt, dass Preisdiskriminierungbeim Netzzugang korrigierend bei Marktversagen wirken und auch zur Erhöhung der Produktionsmenge (also Transportvolumina) führen kann. Im Gegensatz ...

    The Impact of Governance Structure on Firm Performance: An Application to the German Water Distribution Sector

    This paper investigates the impact of governance structure on firm performance (i.e., retail prices) using a database of 765 German water suppliers. Controlling for scale economies as well as technical and structural characteristics, we find that private sector participation is accompanied with higher retail prices. Furthermore, Eastern states on average feature higher prices mirroring significant ...

    What's Banking Sector Concentration Got to Do with Private Equity Market?

    The paper investigates the link between bank concentration and a country's buyout market. We perform a macro level analysis for 15 European countries during 1997-2007. We estimate the elasticity of the country i's buyout market to country i's concentration in the banking sector. Our major finding suggests that the more concentrated the banking sector is, the better it is for the size of the buyout ...

    Agenda for Building a New Financial Market Architecture

    Since the summer of 2007, participants in financial markets have been confronted by a crisis of their own making. In order to prevent the recurrence of a similar crisis in the future, the G-20 nations, at their finance summit in Washington on 15 November 2008, resolved to "ensure that all financial markets, products and participants are regulated or subject to oversight, as appropriate to their circumstances." ...

    Overcoming Data Limitations in Nonparametric Benchmarking: Applying PCA-DEA to Natural Gas Transmission

    This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited observations are available. We apply PCA-DEA for radial efficiency measurement to US natural gas transmission ...

    Benchmarking and Firm Heterogeneity in Electricity Distribution: A Latent Class Analysis of Germany

    In January 2009 Germany introduced incentive regulation for the electricity distribution sector based on results obtained from econometric and nonparametric benchmarking analysis. One main problem for the regulator in assigning the relative efficiency scores are unobserved firm-specific factors such as network and technological differences. Comparing the efficiency of different firms usually assumes ...

    Financial Constraints and Continental Business Groups: Evidence from German Konzerns

    Using a unique large panel of German firms, we examine whether participation in business groups (Konzerns) reduces the sensitivity of investment to cash flow. The main finding is that the investment sensitivity is significantly reduced for small firms. On the other hand, we do not find clear evidence that medium-sized and large firms participating in Konzerns have different sensitivity compared to ...
