Description The purpose of this research is to establish the market structure of the mattress manufacturing industry of Ecuador and the relationships between the concentration, local market prices, exchange rate, and profitability variables. A simultaneous equations regression model of partial three-stage least squares (3SLS) with information of the companies with the largest market share in the sector has been used. Market concentration has been calculated using the Herfindahl-Hirschman Index. The main results show that there is an imperfect market structure and that market share affects the profitability of the oligopoly. In turn, the oligopoly fails to exercise market power due to the competitiveness in the prices of imported mattresses.
La presente investigación tiene como objetivo establecer la estructura de mercado de la industria de fabricación de colchones en el Ecuador y las relaciones que presentan las variables concentración, precios del mercado local, tipo de cambio y rentabilidad. Se utiliza un modelo de regresión de ecuaciones simultáneas de mínimos cuadrados en tres etapas (MC3E) con información de las empresas con mayor cuota de mercado del sector. La concentración de mercado se calcula utilizando el índice Herfindahl – Hirschman. Los principales resultados exhiben que existe una estructura de mercado imperfecta y que la cuota de mercado incide en la rentabilidad del oligopolio. El oligopolio a su vez no ejerce poder de mercado, por la competitividad en precios de los colchones importados.
