The problem of demand discontinuity in the original Hotelling (1929) model with linear transport costs and a uniform distribution of consumers on an interval can be solved either by introducing quadratic transport costs (d'Aspremont et al, 1979) or by going to a two-dimensional space...

En este trabajo se muestran condiciones para la unicidad del equilibrio de Nash-Cournot para un juego de n-firmas. Estas condiciones garantizan que las funciones de mejor respuesta para n-firmas que compiten en forma oligopolica a la Cournot sean contracciones y generalizan las condiciones de...

We consider a two-periods-model of differentiated duopoly. Firms produce an en-ergy consuming household durable differentiated by its energy efficiency. Consumers differ by the weight they apply to their future energy costs when deciding which product to buy. In line with the Japanese Top Runner...

A coarse certification provides simple, but incomplete information about quality. Its main rationale is to help consumers trade off dimensions of quality that are complex and lack salience. In imperfectly competitive markets, it may induce excess bunching at the certification requirement, crowd...

This paper shows that firms respond strategically to ENERGY STAR, a voluntary certification program for energy-efficient products. Firms offer products that bunch at the certification requirement, differentiate certified products in energy and non-energy dimensions, and charge a price premium on...

Electricity systems are increasingly characterized by distributed generation technologies, e.g. rooftop photovoltaic systems, which are used by end consumers to directly produce electricity. Additionally, empirical evidence suggests that electricity retailers exercise market power in many...
