Overcontribution in experiments on voluntary contribution to a public good has not yet received a fully satisfactory explanation. In those experiments, subjects cooperate, in contradiction with the game-theoretic prediction. In contrast, in oligopoly-experiments and common pool resource...

The gap between the interest rates of different members of the European Monetary Union (EMU) points out to an imperfect degree of financial integration despite the common currency. This paper develops a two-country New Open Economy Macroeconomics (NOEM) model with imperfect financial integration...

In Bikhchandani, Hirshleifer, and Welch\'s (1992) specific model, it is showed that conformist behaviors can emerge due to information externalities. In this note we establish that this result, based on `informational cascades\', heavily depends on the choice of a particular tie-breaking...

On the basis of the recent concepts of epistemic communities and communities of practice, we show that the firm can be defined according to a form of double duality: cognitive and organisational. The interest of this approach is to put ahead the differentiated behavior from the manager and the...

This paper examines a game-theoretical model of parimutuel betting markets with asymmetric information. Generically, all Bayesian-Nash equilibria of the simultaneous game are characterized depending on the number of bettors and the quality of their private information. An equilibrium where all...
