In this paper we show that free entry decisions may be socially inefficient, even in a perfectly competitive homogeneous goods market with non-lumpy investments. In our model, inefficient entry decisions are the result of risk-aversion of incumbent producers and consumers, combined with...

According to the European Commission, Svenska Kraftnät, the Swedish network operator, might have violated competition rules by limiting cross-border transmission capacity to relieve congestion within Sweden. Eventually, the case was settled and Svenska Kraftnät offered commitments to address...

This paper looks at the potential effect of partial ownership on the generation and the transmission sector of electricity markets. Ideally, in liberalized electricity markets, transmission is separated from generation. The transmission sector is a natural monopoly operated by a regulated...

This paper derives the optimal mix of generation technologies in the electricity sector and discusses how this mix will be achieved in a perfectly competitive electricity market. It then studies the detrimental effect of a price cap on short-term profitability and long-run investment incentives...

This paper examines a decade of retail competition in the Dutch electricity market and discusses market structure, regulation, and market performance. We find a proliferation of product variety, in particular by the introduction of quality-differentiated green-energy products. Product innovation...

We model the optimal regulation of continuous, irreversible, capacity expansion, in a model in which the regulated network firm has private information about its capacity costs, investments need to be financed out of the firm's cash flows from selling network access and demand is stochastic. If...

This paper studies the welfare implications of using market mechanisms to allocate transmission capacity in recently liberalized electricity markets. It questions whether access to this essential facility should be traded on a market, or whether the incumbent should retain exclusive usage...

The liberalization of the electricity sector increases the need for realistic and robust models of the oligopolistic interaction of electricity firms. This paper compares the two most popular models: Cournot and the Supply Function Equilibrium (SFE), and tests which model describes the observed...
