A product set of pure strategies is a prep set ("prep" is short for "preparation") if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exists in a class of strategic games satisfying...

Abstract. In the 1980s and at beginning of the 1990s the debate on expectation formation mechanism was dominated by the rational expectation hypothesis. Later on, more interest was directed towards alternative approaches to expectations analysis, mainly based on the bounded rationality paradigm...

If choices depend on the decision maker's mood, is the attempt to derive any consistency in choice doomed? In this paper we argue that, even with full unpredictability of mood, the way choices from a menu relate to choices from another menu exhibits some structure. We present two alternative...

This paper proposes a framework to examine business ethical dilemmas and business attitudes towards such dilemmas. Business ethical dilemmas can be understood as reflecting a contradiction between a socially detrimental process and a self-interested profitable consequence. This representation...

Many decision models in marketing science and psychology assume that a consumer chooses by proceeding sequentially through a checklist of desirable properties. These models are contrasted to the utility maximization model of rationality in economics. We show on the contrary that the two...

A sophisticated player is an individual who takes the action of the opponents, in a strategic situation, as determined by decision of rational opponents, and acts accordingly. A sophisticated agent is rational in the choice of his action, but ignores the fact that he is part of a strategic...

We study boundedly rational players in an interactive situation. Each player follows a simple choice procedure in which he reacts optimally against a combination of actions of his opponents drawn at random from the distribution generated by a player's beliefs. By imposing a consistency...

This article focuses on management indicators, their emergence, theirs functions and their impact for a public action. It does so through an analysis of the implementation of indicators in three forest management units in Belgium, France and Luxembourg. M. Crozier theory and M. Callon theory are...
