We test the hypothesis that smiles perceived as honest serve as a signal that has evolved to induce cooperation in situations requiring mutual trust. Potential trustees (84 participants from Toulouse, France) made two video clips averaging around 15 seconds for viewing by potential senders...

In this paper we show that unlike in Bayesian frameworks asymmetric information does matter and can explain differences in common knowledge decisions due to ambiguous character of agents' private information. Agents share a common-but-not-necessarily-additive prior beliefs represented by...

In this paper, we extend Aumann’s (Ann Stat 4:1236–1239, 1976) probabilistic agreement theorem to situations in which agents’ prior beliefs are represented by a common neo-additive capacity. In particular, we characterize the family of updating rules for neo-additive capacities, which are...

Two rationality arguments are used to justify the link between conditional and unconditional preferences in decision theory : dynamic consistency and consequentialism. Dynamic consistency requires that ex ante contingent choices are respected by up dated preferences. Consequentialism states that...

Many theories of updating under ambiguity assume either dynamic consistency or consequentialism to underpin behaviorally the link between conditional and unconditional preferences. To test the descriptive validity of these rationality concepts, we conduct a dynamic extension of Ellsbergʼs...

Until recently, the field of strategy has neglected the question of what it means to be a strategist. Based on an analysis of 68 interviews with strategy practitioners, our results highlight four main tensions that emerge from strategists' discourses on strategizing work: the social tension, the...

The process of development is linked to the rise of an integrated and competitive economy and polity that allow a maximal division of labor and innovation. This process relies on two intertwined dynamics. First, in the establishment of the rule of law, legal instruments are appropriated by those...

The resolution of a concrete problem lies at the heart of action research approaches. The purpose of this paper is to illustrate the practical difficulties implied by the adoption of a participative approach where the problem to be solved is constructed collaboratively with organizational...

We show that essentially every communication equilibrium of any finite Bayesian game with two players can be implemented as a strategic form correlated equilibrium of an extended game, in which before choosing actions as in the Bayesian game, the players engage in a possibly fin nitely long (but...

This article aims at supplying an interpretative frame of the long-term Malagasy trajectory by redrawing the structuring knots of its political economy. The concomitance of periods of economic expansion and political crises leash indeed to suppose that one of the essential sources of the...
