In this paper we characterize equilibria in a quantity game where symmetric firms face a local demand together with an export-constrained demand. Firms have unlimited access to a local demand but a restricted access to a second market, like in the electricity network where generators compete to...

This paper shows that, unlike what has been found in other papers, a hydro reservoir is an effective tool to exercise market power. Its appealing as a tool is enhanced by the fact that there is no need to constrain total hydro production - a practice too easy to detect -; it suffices to distort...

We derive a measure of firm speed of price adjustment that is directly inversely related to market power and compare this to the measure derived by Martin (1993). However, both measures are incorrect when firms have price conjectural variations. This is because Taylor expansions of the demand...

This article lays down economic principles that should govern electricity transmission pricing when peak-load pricing is used to set tariffs. Transmission systems perform three different functions: to transport energy, to substitute for generation capacity, and to increase competition in the...

The paper analyzes calling party pays access pricing policies in a General Equilibrium two ways access charge model with consumers that choose between different telecommunication providers, and benefit from making calls to other consumers and from the calls that they receive. We obtain that...

The static production efficiency model and the dynamic duality model of intertemporal decision making using a parametric approach have been continuously developed but in separate direction. The parametric approach takes statistical noise into account, which consequently provides accurate...

Cournot oligopoly has been studied almost exclusively under the implicit assumption of perfectly competitive factor markets. However,oligopolistic firms procure often factors of production from imperfectly competitive markets. Okuguchi(1998,2000) has analyzed Cournot oligopoly under the...

This paper uses household-level data of cellular usage to provide estimates of the implied switching costs that preclude consumers from switching providers in the face of competing offers. Our estimation differs from previous switching costs studies in that we are able to observe individual...
