We generalize von der Fehr and Harbord's (1993) multi-unit auction model for the case of a deterministic demand allowing for any technology mix and elastic demand in order to account for demand side bidding. We obtain a general characterization of the equilibrium and show that the Cournot model...

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...

Several regulatory authorities worldwide have recently imposed forward contract obligations on electricity producers as a way to mitigate their market power. In this paper we investigate how such contractual obligations affect equilibrium bidding in electricity markets, or in any other...

We develop a theoretical model of long-run investment decisions on capacity in the context of a liberalized electricity market. The sector's idiosyncrasies such as the uncertainty surrounding future supply and demand, as well as technological constraints, are explicitly modelled. The model is...

The purpose of this Paper is to study the determinants of the concentration of ownership in a privatized, regulated firm. The discussion illustrates some aspects of the costs and benefits of different corporate systems. Privatized utilities are large firms with professional management: there is...

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an...

Labour market regulations have often being blamed for high and persistent unemployment in Europe, but evidence on their impact remains mixed. More recently, attention has turned to the impact of product market regulations on employment growth. This Paper analyses how labour and product market...

The EU faces challenges in reforming the Gas and Electricity Directives to implement the single market in electricity and gas. The Paper argues that there is unfinished business in the areas of regulation, restructuring, encouraging proper risk management through contracting, and designing...

Estimating markups has a long tradition in industrial organization and international trade. Economists and policy makers are interested in measuring the effect of various competition and trade policies on market power, typically measured by markups. The empirical methods that were developed in...

I revisit the relation between aftermarket power and basic market competition. I consider an infinite period model with overlapping consumers: in each period, one consumer is born and joins one of the existing installed bases, then aftermarket payoffs are received by sellers and consumers, then...
