    Abstract

    Esta investigación aporta una visión panorámica del escenario competitivo de la industria de los PCs en los mercados del continente americano con mayor volumen de ventas. En él se describen los cambios producidos por el proceso de migración hacia la portabilidad que caracterizó el período 2005 - 2007. A partir de la estimación de un modelo de elección discreta Logit con coeficientes aleatorios, se recuperan los costes marginales a nivel de producto. A su vez, se desarrolla un análisis regional del ejercicio de poder de mercado por grupos de marcas basado en el Índice de Lerner, que revela que los cambios observados fueron gobernados principalmente por variaciones en la elasticidad-precio de la demanda. En particular, la incorporación de consumidores con una mayor elasticidad en el fragmento de portátiles en Latinoamérica podría explicar bajos niveles de poder de mercado (márgenes) en un contexto de precios a la baja y aumento de la demanda. Palabras clave: productos diferenciados, demanda, oligopolio, poder de mercado, Índice de Lerner, Logit con coeficientes aleatorios, PC. JEL: D12, F23, L13, L63.
