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...

This article extends the traditional electricity peak-load pricing model to include transmission costs. In the context of a two-node, two-technology electric power system, where suppliers face inelastic demand, we show that when the marginal plant is located at the energy-importing center,...

En este trabajo se estudia el grado de sustitución entre la telefonía fija y móvil en Chile. Los resultados muestran que la posesión de al menos un teléfono móvil en el hogar reduce el gasto promedio mensual en teléfono fijo en aproximadamente $5400 (31%). A pesar de lo anterior, el...

This paper explores marginal cost pricing in hydro-thermal power industries. As in standard peak-load pricing for all-thermal electric systems, pricing consists of an energy charge and a capacity charge. However, the marginal cost of hydro generation now includes the value of water, which is...

This paper analyzes market power in price-regulated power industries. We derive market equilibrium under different assumptions (perfect competition, monopoly, Cournot, etc.), with and without free entry. We show that when peak-load pricing is used, producers can exercise market power by...

El propósito de este artículo es establecer los principios económicos que deben regir el cálculo de las tarifas de transmisión de energía cuando se utiliza el modelo tradicional de peak-load pricing para tarificar la energía y la potencia. Los sistemas de transmisión cumplen tres...
