This paper analyzes the pro-competitive effects of financial long-term contracts in oligopolistic electricity markets. This is done in a model that incorporates the main features of the industry: non-storable production, time-varying price-elastic demand, and sequential investment and production...

This paper explains why developed countries impose more trade barriers on middle-income countries than on either poor or other developed countries. The authors use a median voter model of the choice between trade and autarky embedded within an intraindustry trade model similar to Paul Krugman...

The author considers a two-factor (capital and labor), two-good (consumption and investment goods), one-country, overlapping-generations model. For the case in which the closed economy follows an efficient path, the author proves, that if trade lowers (raises) the relative price of the...

A number of countries with oligopolistic power industries have used marginal cost pricing to set the price of energy for small customers. This course of action, however, does not necessarily ensure an efficient outcome when competition is imperfect. The purpose of this paper is to study how the...

This note shows how the transmission system can enhance competition in price-regulated power industries, thus extending earlier findings reported in the literature for deregulated industries. In the context of a two-technology, price-regulated power industry, we show that the interconnection of...
