The paper has as a starting point the work of the philosopher Professor D. Lewis.We provide a detailed presentation and complete analysis of the sender/receiver Lewis signaling game using a game theory extensive form, decision tree formulation. It is shown that there are a number of Bayesian...

We show, by employing a density result for probability measures, that in games with a finite number of players and infinite-dimensional pure strategy spaces Nash equilibria can be approximated by finite mixed strategies. Given < epsilon >0, each player receives an expected utility payoff < epsilon >/2 close to his...</epsilon></epsilon>

The purpose of this note is to discuss the envelope relationship between long run and short run cost functions. It compares the usually presented relationship with one of different form and implications, resulting from a simple production function and constant prices. It points out in particular...

In the context of finite extensive form games, we consider games of imperfect and perfect recall. We look briefly at the famous Kuhn theorem. However we are mainly concerned with imperfect recall games in which paths can intersect information sets in more than one node. Explicit examples are...

We consider zero-sum and a non zero-sum games of two players with generalized, not necessarily linear, utility functions and infinite, compact pure strategy spaces. Emphasis is given to comparisons with results obtained in mathematical theorems. The games chosen make specific points in relation...

One of the main problems in current economic theory is to write contracts which are Pareto optimal, incentive compatible, and also implementable as a perfect Bayesian equilibrium of a dynamic, noncooperative game. The question arises whether it is possible to provide Walrasian type or...

The paper explains by means of two detailed examples that Nash Equilibria in zero-sum games can be obtained through the application of linear programming and maximin calculations. It also discusses, for the same purpose, the application of Kuhn-Tucker theory. In particular, with respect to the...
