Résumé en anglais

This paper analyzes the provision of multiple ecosystem services (ES) by several providers (e.g. farmers) and the negotiation process over their payments by many beneficiaries, who are each interested in one specific type of ES. We determine the main factors that influence the beneficiaries and providers’ preferences to negotiate individually or collectively. These factors are the number of providers, the marginal product of ecosystem acreage, and the cost/benefit ratio of ecosystem conservation through the payment for ecosystem services (PES). Using Nash-in-Nash bargaining, we show that four Nash equilibria can emerge. In equilibrium, beneficiaries and providers can both negotiate individually or collectively while facing opponents acting individually or collectively. We provide a welfare characterization of all the four equilibria that arise from the bargaining game. We show that the two equilibria in which beneficiaries negotiate collectively can implement the first-best.< Réduire
