This paper presents a duopoly model of firm rivalry in a vertically differentiated industry when market dynamics is explicitly accounted for. It shows how the interplay between demand (degree of product differentiation, demand elasticity) and cost (fixed and quality costs) factors determine...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

This paper analyzes the impact of product market competition on unemployment, wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity. It is shown that while more intense competition in the product market increases...

This paper considers the effects of labels in a vertically differentiated duopoly. A label certifies the level of a product's measurable characteristic. It is shown that the certification label chosen by a private (for profit) certifier is lower than both the socially optimal and the firm's...

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 compare the performance of R&D cooperation and R&D competition within the eco-industry using a model of vertical relationship between a polluting industry and the eco-industry. The polluting industry is assumed perfectly competitive and the eco-industry is a duopoly in the market for...

Patenting and licensing are introduced into the lab-equipment horizontal innovation model of endogenous growth. Patent length is not deterministic, in that patent holders' market power will collapse if and only if their patented goods get successfully imitated. The model is solved in an exact...
