In this paper we describe the Spanish electricity industry and its current regulatory regime. Special emphasis is given to the description and discussion of market design issues (including stranded cost recovery), the evolution of market structure, investment in generation capacity and network...

This paper analyzes a model of capacity choice followed by price competition under demand uncertainty. Under various assumptions regarding the nature and timing of demand realizations, we obtain general predictions concerning the role of demand uncertainty on equilibrium outcomes. We show that...

The recent debates over discriminatory versus uniform-price auctions in the UK and elsewhere have revealed an incomplete understanding of the limitations of some popular auction models when applied to real-world electricity markets. This has led certain regulatory authorities to prefer...

In this paper we investigate the factors contributing to the fall in the Lerner Index (price-cost margin) in the British electricity market during the 90s. A first stage of our analysis models the number of breaks in the Lerner Index and their dating as unknowns. Our results suggest the...

\We analyze the time-series of prices in the Spanish electricity market by means of a time varying-transition-probability Markov switching model. Accounting for changes in demand and cost conditions (which reflect changes in input costs, capacity availability and hydro power), we show that the...

We analyze the time-series of prices in the Spanish electricity market by means of a time varying-transition-probabilities Markov Switching model. Accounting for demand and supply conditions, we show that the time-series of prices is characterized by two significantly different price levels....

We develop a continuous-time dynamic model with switching costs. In a relatively simple Markov Perfect equilibrium, the dominant firm concedes market share by charging higher prices than the smaller firm. In the short-run, switching costs might have two types of anti-competitive effects: first,...
