Formation et calcul des prix : le travail de tarification dans la grande distribution

Sociologists have recently been rasing questions about how prices are set in various markets. Although their seminal studies have explained the many processes and variables that come into play, they do not enable us to describe the concrete procedures whereby prices are actually calculated. This empirical case study explores the sophisticated methods of calculating the prices of products distributed in a French retail hypermarket chain. Three major conclusions are drawn. First of all, the law enters into the delimitation of the “space” for calculating the prices that distributors set for selling to consumers. Secondly, the choice of a procedure for performing the calculation affects the balance of power between marketing professionals in the struggle to control their shares in the value. Thirdly, the “consumer sale price” does not result directly either from the relation between supply and demand or from micronegotiations between suppliers and distributors. Instead, it tends to ensue from the linkage between several, heterogenous “spaces” of calculation. This study describes the actors, tools and know-how involved in defining these spaces.
