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...

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...

Ensuring generation adequacy has been an issue for regulators all over the world. Guaranteeing the necessary quantities at an efficient price is not an easy feat in the electricity field. In Colombia, the situation is further aggravated by a generating sector mostly made out of hydraulic plants,...

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...
