Three types of interactions – discursive, translating and based on experience – allowed actors to improvise consistently and manage the critical aspects of the 2003 French heat wave. Our study suggests that managers should help to generate these interactions during crisis response. It also...

In this paper we analyse the risk attitude of a group of heterogenous agents and we develop a theory of comparative collective risk tolerance. In particular, we characterize how shifts in the distribution of individual levels of risk tolerance affect the representative agent's degree of risk...

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk averse variational preferences. No-arbitrage conditions are given in terms of risk adjusted priors. A sufficient condition for existence of efficient allocations is the overlapping...

This research explores the effect of the introduction of online reverse auctions (ORAs) on interorganizational trust between buyers and suppliers in the retail industry. Building upon the notion of the spirit of the technology and the organizing vision, we shed light on the "equivoque" nature of...

To charitable organizations, catalogue mail order firms offer an opportunity to expand both database and revenue. But an offer must be made very carefully since motivation for a donation (altruistic) seems incompatible with that of a purchase (economic). This research is designed to study the...

Prevention policies against flood, such as dams or levees, are commonly designed by local jurisdictions and for most they exert externalities on neighboring jurisdictions. Each jurisdiction chooses its collective prevention effort depending on the insurance system that covers its inhabitants. As...

Under the going concern principle, an entity is considered as a going concern in the absence of information proving the contrary. Over the last thirty years, researchers have extensively examined the information relevant to default risk assessment. These empirical works have turned to be highly...

We consider the general model of zero-sum repeated games (or stochastic games with signals), and assume that one of the players is fully informed and controls the transitions of the state variable. We prove the existence of the uniform value, generalizing several results of the literature. A...
