The purpose of this paper is twofold. First, we generalize Kajii et al. (2007), and provide a condition under which for a game v, its Mobius inversion is equal to zero within the framework of the k-modularity of v for k = 2. This condition is more general than that in Kajii et al. (2007)....

This paper proposes a class of weak additivity concepts for an operator on the set of real valued functions on a finite state space \omega, which include additivity and comonotonic additivity as extreme cases. Let \epsilon be a collection of subsets of \omega. Two functions x and y on \omega are...

This paper proposes a class of weak additivity concepts for an operator on the set of real valued functions on a finite state space Ω, which include additivity and comonotonic additivity as extreme cases. Let E ⊆ 2Ω be a collection of subsets of Ω. Two functions x and y on Ω are...

Two of the most important ideas in economics and law are the “Coase Theorem” and the “Prisoner’s Dilemma.” In this paper, the authors explore the relation between these two influential models through a creative thought-experiment. Specifically, the paper presents a pure Coasean version...

Classify simple games into sixteen "types" in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and computability. For each such class, we either show...

Classify simple games into sixteen “types” in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and algorithmic computability. For each such class,...

This work shows that defective behaviors from the cooperative equilibrium in the management of common resources can be fueled and triggered by the presence of agents with myopic behaviors. The behavior implemented by naïve agents, even if performed with cooperative intent, can activate a...

Hierarchy plays an integral role in organizational structure and practices, as well as in society more generally. In Confucian-influenced cultures, and especially in South Korea, social hierarchies are often based on age, and age dynamics can therefore influence social decision-making and...
