This paper contributes to the theory of rational choice under multiple criteria. We perform a preliminary study of the properties of decision made by the sequential application of rational choices. This is then used to obtain a characterization of set-valued choice functions that are rational by...

This paper is concerned with the axiomatic foundation of the revealed preference theory. Many well-known results in literature rest upon the ability to choose over budget sets that contains only 2 or 3 elements, the situations which are not observable in real life. In order to give a more...

Presented is an evolutionary model of consumer non-durable markets, which is an extension of a previously published paper on consumer durables. The model suggests that the repurchase process is governed by preferential growth. Applying statistical methods it can be shown that in a competitive...

We define a bargaining set for finite economies using Aubin’s veto mechanism and show its coincidence with the set of Walrasian allocations. Then, we rewrite our notion in terms of replicated economies showing that, in contrast with Anderson, Trockel and Zhou’s (1997) non-convergence result,...

We analyze bargaining mechanisms for allocating resources in atomless econo- mies. We provide results proving that it is not necessary to consider the forma- tion of all coalitions in order to obtain the bargaining sets. This is shown under restrictions of different nature, triggering different...

In most of the Intermediate Microeconomics or Microeconomic Theory texts, when the demand of individuals subject is analyzed, especially the Price-Consumption paths and Income-Expansion paths , Examples are presented in which the utility functions correspond to regular preferences, that is, the...

This document analyzes the changes that suffer the amounts demanded of a good, due to changes in its price. For this we use the decomposition in Income and Substitution effects posed by Slutsky and Hicks in their work concerning the analysis of the demand. In general, when the price of a good...

This paper characterizes different belief revision rules in a unified framework: Bayesian revision upon learning some event, Jeffrey revision upon learning new probabilities of some events, Adams revision upon learning some new conditional probabilities, and `dual-Jeffrey' revision upon learning...

We conduct a proper test of the claim that people are overconfident, in the sense that they believe that they are better than others. The results of the experiment we present do not allow us to reject the hypotheses that the data has been generated by perfectly rational, unbiased, and...

Many studies have shown that people display an apparent overconfidence. In particular, it is common for a majority of people to describe themselves as better than average. The literature takes for granted that this better-than-average effect is problematic. We argue, however, that, even...
