Abstract

El presente trabajo desarrolla una metodología de estimación de sistemas de demanda, que sirve para calcular la elasticidad crítica a utilizar en la definición de mercados relevantes dentro de un sector en particular, y para simular los efectos unilaterales de fusiones horizontales que puedan producirse entre empresas que operan en dicho sector. Todo el método se basa en la utilización de las distintas elasticidades de largo plazo estimadas, y es esencialmente el mismo para definir los mercados y para simular las fusiones. El trabajo concluye con una ilustración empírica del método, que utiliza datos de los mercados argentinos de cerveza y de galletitas.
