Le rôle de la certification dans les changements de régime de coordination : l'agriculture biologique, du réseau à l'industrie

The "convention theory" agrees with the idea that the market mechanisms are not sufficient for explaining economic coordination and states the assumption that actors use conventional indicators for defining goods quality.
