Strong convexity of NTU games

نویسنده

چکیده

In this paper, we provide an alternative definition of NTU convexity, strongly ordinal convexity. We show that if a game is strongly ordinal convex, then any marginal worth vector is in the core, and any marginal contribution is increasing. Some economic examples satisfy this convexity.

Convex and exact games with non-transferable utility

We generalize exactness to games with non-transferable utility (NTU). In an exact game for each coalition there is a core allocation on the boundary of its payoff set. Convex games with transferable utility are well-known to be exact. We study five generalizations of convexity in the NTU setting. We show that each of ordinal, coalition merge, individual merge and marginal convexity can be unifi...

The strong sequential core for stationary cooperative games

Infinite time horizon stationary cooperative games are considered where at each date the instantaneous NTU-game is determined by the state of nature. The strong sequential core selects those utility streams that no coalition can improve upon by deviating at any moment in time. The main result of the paper states that the strong sequential core is non-empty provided that (i) the instantaneous NT...

Fractional Solutions for NTU-Games

In this paper we survey some applications of Scarf’s Lemma. First, we introduce the notion of fractional core for NTU-games, which is always nonempty by the Lemma. Stable allocation is a general solution concept for games where both the players and their possible cooperations can have capacities. We show that the problem of finding a stable allocation, given a finitely generated NTU-game with c...

Random marginal and random removal values

We propose two variations of the non-cooperative bargaining model for games in coalitional form, introduced by Hart and Mas-Colell (1996a). These strategic games implement, in the limit, two new NTU-values: The random marginal and the random removal values. The main characteristic of these proposals is that they always select a unique payo¤ allocation in NTU-games. The random marginal value coi...

Single NTU-value solutions¤

We propose a variation of the non-cooperative bargaining model for n-person games in coalitional form, introduced in Hart and Mas-Colell (1996). This strategic game implements, in the limit, a new NTU-value for the class of monotonic games. This value coincides with the Consistent NTU-value (Maschler and Owen,1989) for hyperplane games, and with the Shapley value for TU games (Shapley, 1953). T...
