We use a game-theoretic model to analyze the impacts of a hypothetical fleet of plug-in electric vehicles on the imperfectly competitive German electricity market. Electric vehicles bring both additional demand and additional storage capacity to the market. We determine the effects on prices,...

We show that a common regulatory mandate in electricity markets that use location-based pricing that requires all customers to purchase their wholesale electricity at the same quantity-weighted average of the locational prices can increase the performance of imperfectly competitive wholesale...

We construct a model of strategic behavior in sequential markets which exhibits a persistent forward price premium. On the spot market, producers wield market power while purchasers are price takers. Producers with forward commitments have less incentive to raise prices on the spot market....

Competition between oligopolist electricity generators is inhibited by transmission constraints. I present a supply function equilibrium (SFE) model of an electricity market with a single lossless, but constrained, transmission line. The market admits equilibria in which generator withhold...

Market power in electricity wholesale markets arises when generators have incentives to mark up their offers above the cost of production.I model a transmission network with a single line. I derive optimality conditions for supply functions for generators who supply energy at both ends of the...

We apply a multi-equation dynamic econometric model on monthly data to test if the behaviour of OPEC as a whole or different sub-groups of the cartel is consistent with the characteristics of dominant producers on the world crude oil market in the period 1973-2001. Our results indicate that the...

We study consumer surplus in a single market when (a) there is a lower bound in the consumption of the outside good and (b) the weights in the social welfare function given to consumers and firms are different. We assume quasilinear utility. When the lower bound constraint on the consumption of...

We analyze the impacts of a hypothetical fleet of plug-in electric vehicles on the imperfectly competitive German electricity market with a game-theoretic model. Electric vehicles bring both additional demand and additional storage capacity to the market. We determine their effects on prices,...

It is well known that uncertainty concerning firms’ costs as well as market power of the latter have to be taken into account in order to design and choose environmental policy instruments in an optimal way. As a matter of fact, in most actual regulation settings the policy maker has to face...

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...
