We study the asymptotic properties of the Shapley value of patent licensing games with the Cournot competition, shedding light on its relations to the nucleolus, core and bargaining set. The Shapley value of the outside patentee of a non-drastic cost-reducing innovation converges to 2(a − c), which coincides with the patentee’s profit through non-cooperative licensing by means of upfront fee (o...

Motivated by the problem of utility allocation in a portfolio under a Markowitz meanvariance choice paradigm, we propose an allocation criterion for the variance of the sum of n possibly dependent random variables. This criterion, the Shapley value, requires to translate the problem into a cooperative game. The Shapley value has nice properties, but, in general, is computationally demanding. Th...

We consider the problem of the axiomatization of the Shapley value on the class of assignment games. We show that Shapley’s original [21], Young’s [24], Chun’s [7], van den Brink’s [2], (5-6) Hart and Mas-Colell’s [12] potential function and consistency approaches and Roth’s [19] characterization do not work on the class of assignment games. We also consider Myerson’s [15] axiomatization of the...

The paper starts by proposing an explicit and intuitive bargaining process to analyze coalitional externalities, which we then use to generate a value allocation extending the Shapley value to partition function from games, the Rational Belief Shapley value (RBS). We investigate the strategic foundation of the value by constructing a mechanism implementing it. It extends existing models of mult...

We will discuss some relations among values, i.e., global/overall importance of each single element of the object to be considered, interaction indices, i.e., simultaneous interaction among the elements in a coalition, and inclusion-exclusion coverings, i.e., decomposability of non-additive measures and/or of the Choquet integral. So, we show that inclusion-exclusion coverings are characterized...

The principle of differential marginality for cooperative games states that the differential of two players’ payoffs does not change when the differential of these players’ productivities does not change. Together with two standard properties, efficiency and the null player property, differential marginality characterizes the Shapley value. For games that contain more than two players, we show ...

In this paper the Shapley value of digraph (directed graph) games are considered. Digraph games are transferable utility (TU) games with limited cooperation among players, where players are represented by nodes. A restrictive relation between two adjacent players is established by a directed line segment. Directed path, connecting the initial player with the terminal player, form the coalition ...

Every weighted tree corresponds naturally to a cooperative game that we call a tree game; it assigns to each subset of leaves the sum of the weights of the minimal subtree spanned by those leaves. In the context of phylogenetic trees, the leaves are species and this assignment captures the diversity present in the coalition of species considered. We consider the Shapley value of tree games and ...

We prove that the Shapley value of every two-sided exact assignment game lies in the core of the game.

Nota: this compilation of various results has been intended primarily for my personal use, hence its very rough form. It is just a quick reference compilation of results. It is far to be complete, and does not intend to be so especially for references, and I update it from time to time. All comments, discovered mistakes, etc. are welcome. Please be kind enough to cite it in references if you us...
