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...

We investigate in a horizontal product differentiation model with North-South trade the implications of a home bias in consumers' demand for labelled goods. We compare mutual recognition and international harmonisation of ecological labels with respect to firms' profits and welfare. Northern...

We analyze the role of public support in the financing pattern of R&D in German SMEs and their assessment of financing conditions in the context of other framework conditions for innovation. In Germany, there is a diversity of overall well-funded technology-neutral and technology-specific...

The literature argues that research spin-offs (RSOs)-enterprises originating from a university or research institute-appear to have higher innovative potential and capabilities than other start-ups, at least in the early stages of their development. Yet, little is known about the innovative...

We analyze the dynamic effect of prices and price volatility on current oil production, both on the level of country groups and the major individual producer countries. A comprehensive dataset at monthly frequency allows us to include a rich lag structure while controlling for key global and...

We analyze the impacts of a hypothetical fleet of plug-in electric vehicles on the imperfectly competitive German electricity market with a game-theoretic model. Electric vehicles bring both additional demand and additional storage capacity to the market. We determine their effects on prices,...

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...

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...

The German decision to finally phase-out nuclear electricity has led to a debate on its effects on electricity prices, emission prices in the European emission trading system, as well as on international electricity trade. We investigate these effects with a Electricity market model for Europe...
