    Konzentration im Lebensmitteleinzelhandel: Hersteller sitzen am kürzeren Hebel

    Die Konzentration im deutschen Lebensmitteleinzelhandel schreitet weiter voran und rückt das Thema Nachfragemacht mehr und mehr in den Fokus wettbewerbspolitischer Diskussionen. Im Gegensatz zur Angebotsmacht liegen gesicherte empirische Erkenntnisse über das Vorhandensein, das Ausmaß und die Folgen von Nachfragemacht auf den Beschaffungsmärkten des Lebensmitteleinzelhandels in Deutschland bislang ...

    Evidence of Market Power in the Atlantic Steam Coal Market Using Oligopoly Models with a Competitive Fringe

    Before 2004 South Africa was the dominant steam coal exporter to the European market. However a new market situation with rising global demand and prices makes room for a new entrant: Russia. The hypothesis investigated in this paper is that the three incumbent dominant firms located in South Africa and Colombia reacted to that new situation by exerting market power and withheld quantities from the ...

    Perspectives of the European Natural Gas Markets until 2025

    We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic severallayer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall supply situation ...

    Corporate Espionage

    We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some situations ...

    Monetary Policy Transmission and House Prices: European Cross Country Evidence

    This paper explores the importance of housing and mortgage market heterogeneity in 13 European countries for the transmission of monetary policy. We use a pooled VAR model which is estimated over the period 1995-2006 to generate impulse responses of key macroeconomic variables to a monetary policy shock. We split our sample of countries into two disjoint groups according to the impact of the monetary ...

    Liquidity and Asset Prices: How Strong Are the Linkages?

    The appropriate design of monetary policy in integrated financial markets is one of the most challenging areas for central banks. One hot topic is whether the rise in liquidity in recent years has contributed to the formation of price bubbles in asset markets. If strong linkages exist, the inclusion of asset prices in the monetary policy rule can eventually limit speculative runs and negative effects ...
