Una propuesta metodológica para la definición de mercados geográficos relevantes

Sánchez Navarro, Dennis (2012): Una propuesta metodológica para la definición de mercados geográficos relevantes.

Abstract

El punto de partida de cualquier análisis de competencia, consiste en la definición adecuada del mercado tanto en términos de producto como en términos geográficos. Sin embargo, la definición de los límites no siempre resulta sencilla, en particular cuando se refiere a términos espaciales. No obstante, la definición de esos límites del mercado es definitiva para prever la incidencia de cualquier actividad u operación sobre el grado de competencia de un mercado. Por esta razón, el presente documento busca proponer una metodología alterna de definición de mercados geográficos relevantes, retomando el índice Moran y el modelo de rezago espacial (SAR en inglés).

The starting point of every competition analysis consists of the appropriate market definition in terms of product as well as in geographic form. However, the definition of boundaries is not always easy, particularly when it refers to spatial limits. Nonetheless, the definition of those market boundaries is definitive to foresee the effects of some activity or operation (as enterprises merger) on the degree of competition in the market. Hence, the present document proposes an alternative methodology to define relevant geographic markets, using Moran’s Test and Spatial Lag Model (SAR).
