Retailer Market Power and Competition Policy (RETAIL)
Date du début: 1 juin 2010, Date de fin: 31 mai 2012 PROJET  TERMINÉ 

"The expanse of large retailers in recent decades leads to the high concentration in retail market, and the ever-growing market power of large retailers has caused serious concerns on detrimental impacts against small retailers. However, competition authorities face a dilemma in identifying market conditions under which the increase of retailer market power could impair competition. This research aims to provide normative analysis for this purpose, by developing a new model on retail competition based on consumer choices, and characterizing interactions between retailer buyer power against suppliers and seller power against competitors. The research project is based on the preceding work by the applicant, Dr. Zhijun Chen and Professor Patrick Rey, and would be conducted by a research group based on the host institute, the department of economics in Ecole Polytechnique, which consists of the scientist in charge, Professor Patrick Rey, the applicant and other researchers with closely related research interests."
