In this paper, we present the results of an extended traveler behaviour survey conducted in Geneva (Switzerland) in March 1994. In this survey, commuters were asked about the impact of various factors, related to individual or household characteristics and situational, contextual and...

This paper describes the historical evolution of the analysis of some aspects of the strategic use of information. The use of mixed strategies aims to create uncertainty on the move to be played or on the private information of the players. In a repeated game framework, strategic behavior when...

We present a general framework for understanding the transition from local regular to global irregular (chaotic) behavior of nonlinear dynamical models in discrete time. The fundamental mechanism is the unfolding of quadratic tangencies between the stable and the unstable manifolds of periodic...

We analyse the efficiency of output and input incentives schemes in an agency model in both cases of certain and uncertain production.

This paper considers a long-term relationship between a firm and a privately informed trading partner, say a buyer, when both parties bargain over a price in each period and when a toakeover may take place.

We analyze the choice of financial instruments to issue for a firm in a context where informational asymmetries exist in credit relationships. Investors are heterogenous since they do not possess identical firm-specific information. We generalize Boot and Thakor's (1993) approach but depart from...

The high persistence of the PPP deviations is well documented in empirical work about real exchange rates. Our paper explores the possibility that, in presence of e.g. shipping costs, a nonlinear representation is more relevant for the real exchange rate.

This paper investigates the role of probability conditionals in hypothetical reasoning and rational decision making. Its main result is a proof of a representation theorem for preferences defined on sets of sentences (and, in particular, conditional sentences), where an agent's preference for...
