FISHERY MANAGEMENT GAMES: HOW TO ADMIT NEW MEMBERS AND REDUCE HARVESTING LEVELS

This paper applies game theory to address the problem of allocating profits among fishing nations, once the countries concerned have expressed an interest in achieving an agreement through a Regional Fishery Management Organization (RFMO). Proposing the population monotonic allocation scheme as management rule for division of profits, we argue that existing RFMOs can be expanded by means of the Shapley value. We also show that adjustment from the Nash equilibrium to sustainable or more efficient can be achieved by means of the proportional rule without harming any of the countries involved.

A NOTE ON NTU CONVEXITY AND POPULATION MONOTONIC ALLOCATION SCHEMES

For cooperative games with transferable utility, convexity has turned out to be an important and widely applicable concept, mainly because it implies some very nice and handy properties. One of these is that every extended marginal vector constitutes a population monotonic allocation scheme. In this note, this well-known result is generalised to games with nontransferable utility.

INFORMATION SHARING GAMES

In this paper we study information sharing situations. For every information sharing situation we construct an associated cooperative game, which we call an information sharing game. We show that the class of information sharing games coincides with the class of cooperative games with a population monotonic allocation scheme.
