We study the efficient allocation of a divisible asset when reallocation is costly. Each of two players is initially allocated a share of the asset. At the time of this initial division the players’ valuations for the asset are uncertain. After the uncertainty resolves, costly reallocation may take place. Reallocation costs may depend on the amount reallocated and on players’ valuations. We fir...

poisoning remains a major cause of hospital admission into the emergency department and intensive care unit. proper diagnosis is the cornerstone for optimal management of poisoned patients. since the definitive analytical confirmation of the nature of the toxicant involved in the poisoning cannot be rapidly obtained in the majority of healthcare facilities, diagnosis relies on the medical histo...

This paper tries to provide a preliminary description of the mental process individuals experience in their attempt to comprehend stated probabilities of simple lotteries. The evaluation of probabilities is based on three main components: lotteries encountered in the past, the realizations of these lotteries, and the similarity between stated probabilities. A probability is evaluated based on t...

A choice function is a rule that chooses a single alternative from every set of alternatives drawn from a finite ground set. A rationalizable choice function satisfies the consistency condition; i.e., if an alternative is chosen from a set A, then the same alternative is also chosen from every subset of A that contains it. In this paper we study computational aspects of choice, through choice f...

We introduce a new type of agent, whom we refer to as a "problem solver" (PS). The PS interacts with conventional players and wishes to respond optimally to their moves. The PS has only partial information about the moves of the other players. Unlike a regular player, the PS does not "put himself in the shoes" of other players and does not form beliefs about their moves. Rather, he treats the d...
