Droits à produire transférables : Le marché des concessions conchylicoles et ses effets non désirés

This paper sets out an historical analysis of the rights-based system applied to the French shellfish-farming sector and a study of the current operating way of this system. It addresses the issue of the distribution of production means within an industry whose two main characteristics are the familial exploitation model and the specific social objectives like jobs creation in some coastal areas. The shellfish farming rights-based system has evolved toward a transferable production-rights system. However, the spontaneous emergence of a market for production-rights in the context of a weak administrative intervention is likely to generate unintended effects, whose occurrence is tested using quantitative and qualitative data. The final discussion searches for the economic indicators and the regulation tools which could improve the efficiency of the shellfish farming concessions market.
