We characterize choice correspondences that can be rationalized by a procedure that is a refinement of the prudent choices exposed in (Houy, 2010). Our characterization is made by means of the usual expansion axiom [gamma] and a weakening of the usual contraction axiom [alpha]. We also make a...

In this paper, we study the link between choices derived from monotonous set-dependent preferences and sequential rationalizability. This link is quite natural since choices derived from monotonous set-dependent preferences (introduced in [Houy, 2008b]) are characterized by a strong axiom of...

We charaterize the choice correspondences that can be rationalized by a procedure that is a refinement of the prudent choices exposed in [Houy, 2008]. Our characterization is made by means of the usual expansion axiom and by a weakening of the usual contraction axiom α.

This paper analyzes the assignment of durable objects to successive generations of agents who live for two periods. The optimal assignment rule is stationary, favors old agents and is determined by a selectivity function which satisfies an iterative functional differential equation. More patient...

In this paper, we study the relationships between binary lexicographic composition of rationales (see [Tadenuma, 2002]), prudent choices (see [Houy, 2008a]) and refined prudent choices (see [Houy, 2008b]) in the case of multi-criteria decision making. We show that these relationships are linked...

Parikh and Krasucki [1990] showed that if rational agents communicate the value of a function f according to a protocol upon which they have agreed beforehand, they will eventually reach a consensus about the value of f, provided a fairness condition on the protocol and a convexity condition on...

[eng] Payment Efficiency in Euro and Monetary Denomination Systems. . This study aims at measuring the efficiency of the European monetary denomination system. On the contrary to the previous studies based on a uniform distribution of prices in the economy, we introduce a real distribution of...

Intuitively, we might think that a multiproducts company which has the possibility to forecast the structure of demand does not need to protect itself against risks of stock shortages due to the variability of the characteristics of demand since this becomes foreseeable. Symmetrically, it seems...

Parikh and Krasucki [R. Parikh, P. Krasucki, Communication, consensus and knowledge, J. Econ. Theory 52 (1990) 178-189] show that, in a group of rational agents, communication of the value of a function f leads to a consensus on the value of f, provided some conditions on the communication...

It is a widely spread belief that crypto-currencies implementing a proof of stake transaction validation system are less vulnerable to a 51% attack than crypto-currencies implementing a proof of work transaction validation system. In this article, we show that it is not the case and that, in...
