Abstract We discuss competition policy issues of vertical integration in internetbased two-sided markets against the background of the Google antitrust allegations. Network effects and economics of scale often lead to dominating companies, which are integrated over several markets. This implies...

Abstract This paper is concerned with the question of how to deal with Google Shopping’s position on online markets in order to prevent harm to public welfare. From the perspective of sellers and buyers of goods and services in Germany, Google can be seen as a gatekeeper to the Internet and...

Summary In a framework of a monetary asset pricing model with production the effects of monetary and fiscal policy shocks are investigated. The model is kept simple enough to generate explicit formulae for the equilibrium price functions. With money yielding liquidity services in the exchange...

Purpose – This paper aims to examine two hypotheses that have not been well investigated in the existing literature. One hypothesis is that the real interest rates of industrial countries tend to be mean‐reverting during the current floating exchange rate period. Another hypothesis is that...

We examine the behavior of the real exchange rates of nine transition economies during the 1990s. We propose an empirical model rationalized on the basis of standard economic models in the tradition of Mundell-Fleming-Dornbusch and Harrod-Balassa-Samuelson, allowing explicitly for real interest...

Summary This paper expands the empirical analysis of hysteresis in trade in two directions. First, it uses disaggregate data for exports from Germany to the U.S. to minimise aggregation problems. Second, it introduces a new non-linear model to test for the non-linear parameter. The model is...

Abstract This paper discusses market power effects in ambient permit markets. We consider a dominant firm in a position to exert market power in several markets. A first conclusion is that the distortion observed on manipulated markets spreads to other markets. We find that the manipulated...

It may be optimal from a welfare perspective to use R&D subsidies when the source of R&D distortions originates from the surplus appropriability problem and technological spillovers in the form of knowledge spillovers, creative destruction, and duplication externalities are absent. Hence, R&D...

It is a common practice for governments to offer scrappage subsidies in order to stimulate the early removal of used cars and modify the distribution of vehicle holdings. In this paper, we analyze the market implications of such subsidies when producers have market power and face competition...
