Static or dynamic equilibrium notions used in game theory may be justified along two perspectives. From an epistemic point of view, equilibria are grounded on the reasoning of hyper-intelligent players who share a common knowledge of the game structure and of their rationality. If a...

One main topic of the epistemic program of game theory deals with the value of information. To study this question in a broad context, one needs to adapt some of the tools used in multiplayer epistemic logic. A hierarchical belief structure is introduced both in a syntactical and semantical...

The genesis of institutions can be treated by game theory, which is expressed at a sufficiently general level, considers direct relations among agents not mediated by former institutions and respects a sophisticated methodological individualism. In that framework, if interested not in the...

This paper aims at providing a possible explanation for the seemingly peripheral role played by spatial economics in modern economic theory. It considers sucessively five points of view according to which space is introduced in economic models and assesses their contributions and limits.

The paper studies a specific reinforcement learning rule in two-player games when each player faces a unidimensional strategy set. The essential feature of the rule is that a player keeps on incrementing her strategy in the same direction if and only if her utility increases. The paper...
