    Marktstrukturen in der Trinkwasserversorgung

    Mit mehr als 6.000 Unternehmen kann die Trinkwasserversorgung Deutschlands im internationalen Vergleich als höchst fragmentiert angesehen werden. Während die Trinkwasserversorgung in zahlreichen Ländern durch eine ähnliche Fragmentierung gekennzeichnet ist, gibt es aber auch Beispiele höchst konsolidierter Versorgungsstrukturen: so gibt es in England und Wales lediglich 22 Trinkwasserversorgungsunternehmen ...

    The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

    We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand and, based on an oligopolistic model of multiproduct firms, we then recover the marginal costs and ...

    Collusion through Joint R&D: An Empirical Assessment

    This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of RJV-participating firms. Using information from the U.S. National Cooperation Research Act, we estimate a market share equation correcting for the endogeneity of RJV participation and R&D expenditures. We find robust ...

    Does State Antitrust Enforcement Drive Establishment Exit?

    Previous work has shown that state-level antitrust enforcement activity may have impacts on entry and relocation behavior by U.S. firms. Significant state-level antitrust activity may be an indicator of a perceived adverse business environment and it is found to deter establishment entry, particularly for larger firms in the retail and wholesale sectors. An obvious question is whether establishment ...

    Merger Externalities in Oligopolistic Markets

    We quantify externalities on profitability and market shares of competing firms in oligopolistic markets through the transition from an n to an n - 1 player oligopoly after a merger. Competitors are identified via the European Commission's market investigations and our methodology allows us to distinguish the externality due to the change in market structure from the merger effect. We obtain results ...

    Renewable Electric Energy Integration: Quantifying the Value of Design of Markets for International Transmission Capacity

    Integrating large quantities of variable renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns. We model the current methodology for controlling congestion ...

    Location, Location, Location: Extracting Location Value from House Prices

    The price for a single-family house depends both on the characteristics of the building and on its location. We propose a novel semiparametric method to extract location values from house prices. After splitting house prices into building and land components, location values are estimated with adaptive weight smoothing. The adaptive estimator requires neither strong smoothness assumptions nor local ...
