Despite the positive effect electricity grids separated from generation and supply by ownership are expected to have on the level of competition in the non-network activities, several EU member states still adhere to a solely legally unbundled transmission grid. This choice might be induced by...

When deciding whether to introduce market competition into a regulated industry, a regulator faces an important tradeoff. Market-based prices can provide incentives to allocate resources more efficiently and reduce costs, but the presence of market power may lead to increased markups. We use a...

Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. This work proposes a three-stage...

Lack of transmission capacity hampers the efficient integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate to what extent the expansion of the transmission grid promotes competition, efficiency, and welfare. This work...

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...

This paper is a technical report commissioned by Energy Consumers Australia, a statutory advocacy institution, as to the state of the electricity market in Australia. Using standard tools of economics, it finds that the combination of market power, vertical integration and a poor regulatory...
