Résumé en anglais

We present the first steps of a network study of market organization based on the observation and analysis of scheduled meetings between sellers, buyers, distributors, advertisers and producers at an international trade show for television programs. We use a “linked-design” approach in which each level (inter-individual and inter-organizational ) constitutes a specific exchange system of different resources among actors present at this commercial event. We examine levels separately, but also jointly. We raise the issue of the dynamics of such multilevel structures and provide a first approach to such dynamics by looking at individual actors’ trajectories over time in the labor market created by the inter-organizational network of companies represented at this fair.
