Economic theory predicts that it is impossible to have cooperation in finitely repeated games such as a prisoner's dilemma game without communication. In an experiment on a voluntary participation game with a non-excludable public good that is a version of a Hawk-Dove game, we obderved that...

In this paper, we shall provide a theoretical overview of what are the chief implications of fucusing institutions and economic systems, what are the main sources of their evolution, how are their evolutionary paths affected by various economic factors. In the latter half, we shall provide a...

Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1997), we define two types of natural mechanisms quantity and price-quantity types, in convex production economies, and characterize the class of Pareto subsolutions doubly implementable in Nash and strong Nash equilibria...

This paper discusses and develops "non-welfaristic" arguments on distributive justice, mainly basing upon J. Rawls and A.K. Sen, and formalizes, in cooperative production economies, "non-welfaristic" distribution rules as game forms. First, it conceptualizes Needs Principle that the distribution...

This paper examines equilibrioum and stability in symmetric two-player cheap-talk games. In particular, we characterize the set of neutrally stable outcomes in finite cheap-talk 2x2 coordination games.

In the models of Young (1993a,b), boundedly rational indivudals are recurrently matched to play myopic best replies to the recent history of play. It could therefore be an advantage to instead play a myopic best reply tthe myopic best reply, something boundedly rational players might conceivably...

This paper provides deterministic approximation results for stochastic processes that arise when finite populations of boundedly rational agents recurrently play finite games. The deterministic approximation is defined in continuous time in terms of a system of ordinary differential equations of...

We propose an operational concept of Constrained Strategic Equilibrium (CSE) applicable to a broad class of empirical game theoreticmodels with incomplete information. By restricting the players' strategic sets, we can compute solutions from a strategic form of analyis based upon auxiliary Monte...
