Market Power and Efficiency in a Computational Electricity Market with Discriminatory Double-Auction Pricing

Nicolaisen, James; Petrov, Valentin; Tesfatsion, Leigh - EconWPA - 2000

This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market … microstructure is strongly predictive for the relative market power of buyers and sellers, and that high market efficiency is … social mimicry learning via a genetic algorithm. However, market efficiency is substantially reduced. …

Modeling Electricity Auctions

Harbord, David; Fabra, Natalia; Fehr, Nils-Henrik von der - EconWPA - 2002

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...

Modeling highly volatile and seasonal markets: evidence from the Nord Pool electricity market

Weron, Rafal; Simonsen, Ingve; Wilman, Piotr - EconWPA - 2003

In this paper we address the issue of modeling spot electricity prices. After analyzing factors leading to the unobservable in other financial or commodity markets price dynamics we propose a mean reverting jump diffusion model. We fit the model to data from the Nord Pool power exchange and find...

On detecting and modeling periodic correlation in financial data

Broszkiewicz-Suwaj, Ewa; Makagon, Andrzej; Weron, Rafal; … - EconWPA - 2005

For many economic problems standard statistical analysis, based on the notion of stationarity, is not adequate. These include modeling seasonal decisions of consumers, forecasting business cycles and - as we show in the present article - modeling wholesale power market prices. We apply standard...

The Fall in British Electricity Prices: Market Rules, Market Structure, or Both?

Fabra, Natalia; Toro, Juan - EconWPA - 2003

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...

Mediating Market Power in Electricity Networks

Gilbert, Richard; Neuhoff, Karsten; Newbery, David - EconWPA - 2003

We ask under what conditions transmission contracts increase or mitigate market power. We show that the allocation process of transmission rights is crucial. In an efficiently arbitraged uniform price auction generators will only obtain contracts that mitigate their market power. However, if...

Price Wars and Collusion in the Spanish Electricity Market

Fabra, Natalia; Toro, Juan - EconWPA - 2002

\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...
