Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. In this work, we investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. To this end, we...

Central features of today’s electronic communications markets are complementarities between the different layers of the value chain, substitutability between some applications, network effects in the provision of content and services, two-sided business models that partly involve indirect...

In this conceptual paper, I propose a framework for measuring the market power of digital platforms. The rise of big technology companies that act both as intermediary platforms and providers of services and goods in several markets has heightened concerns about potential economic harms brought...

This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

In this paper we check whether generators' bid behavior at the Spanish wholesale electricity market is consistent with the hypothesis of pro?fit maximization on their residual demands. Using OMEL data, we ?find the arc-elasticity of the residual demand around the system marginal price. The...
