Bargaining with intertemporal maximin payoff: Formal problem and general solution under monotonicity

Vincent Martinet Institut national de la recherche agronomique (INRA)

This paper describes a new class of dynamic problems which are called "bargaining problems with intertemporal maximin payoffs". Such problems may reect sustainability issues. Each player (or stakeholder) has a representative indicator, namely a function of the state and decisions, and aims at maximizing its minimal value over time. Bargaining on sustainability objectives consists in de ning the set of stake-holder's payoffs. We are interesting in de ning the feasibility set of alternatives of such problem. This set is interpreted as a support for a social choice sustainability rule. We provide its characterization in a general framework under some monotonicity properties of the dynamics and in so-called "bioeconomic-like" models.
