Forward sales is a credible commitment to aggressive spot market bidding, and it mitigates producers' market power in electricity markets. Still it can be profitable for a producer to make such a commitment if it results in a soft response from competitors in the spot market (strategies are...

This paper characterizes the Nash equilibrium in a pay-as-bid (discriminatory), divisible-good, procurement auction. Demand by the auctioneer is uncertain as in the supply function equilibrium model. A closed form expression is derived. Existence of an equilibrium is ensured if the hazard rate...

In most wholesale electricity markets generators must submit step-function offers of supply to a uniform price auction, and the market is cleared at the price of the most expensive offer needed to meet realised demand. Such markets can most elegantly be modelled as the pure-strategy, Nash...

A Bayesian supply function equilibrium is characterized in a market where firms have private information about their uncertain costs. It is found that with supply function competition, and in contrast to Bayesian Cournot competition, competitiveness is affected by the parameters of the...

Ramsey-Boiteux prices and monopoly prices are frequently regarded as being similar. This might suggest that, in particular in network in- dustries with large fixed costs, sometimes monopoly pricing is close to the Ramsey-Boiteux second best and welfare superior to imperfectly regulated prices....

Scarce interconnector capacities are a severe obstacle to transregional competition and a unified market for electricity in the European Union. However, physically the interconnectors are rarely used up to capacity. This is due to the fact that the current allocation schemes make only limited...

The EU electricity directive (96/92/EC) established the right of the member states to choose between Regulated and Negotiated Third Party Access (RTPA and NTPA). The interest group theory is able to explain whether the introduction of NTPA in Germany had been an interest group equilibrium under...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

Emission trading has become recently more and more import in environmental regulation. In the context of controlling greenhouse gas emissions, the directive on a Europewide trading scheme for large immobile sources may be perceived as one of the most important milestones in recent years. Prior...

The question of third-party access to the networks has become central to the debate around the liberalisation of the European electricity markets due to the natural monopoly characteristic of the transmission network. The European Union?s electricity directive provides three institutional...
