A dynamic theory of fidelity networks with an application to the spread of HIV/AIDS

Pongou, Roland; Serrano, Roberto - 2009

We study the dynamic stability of fidelity networks, which are networks that form in a mating economy of agents of two types (say men and women), where each agent desires direct links with opposite type agents, while engaging in multiple partnerships is considered an act of infidelity....

Age matching patterns and search

Sautmann, Anja - 2010

Consider a marriage market with continuous-time two-sided search and transferable utility in which the match payoff depends on age. This paper characterizes a set of payoff functions consistent with two salient marriage age patterns: (1) assortative matching by age, and (2) \differential age...

The demographic transition: Causes and consequences

Galor, Oded - 2010

This paper develops the theoretical foundations and the testable implications of the various mechanisms that have been proposed as possible triggers for the demographic transition. Moreover, it examines the empirical validity of each of the theories and their significance for the understanding...

Adjusting prices in the many-to-many assignment game

Sotomayor, Marilda - 2008

Starting with an initial price vector, prices are adjusted in order to eliminate the demand excess and at the same time to keep the transfers to the sellers as low as possible. In each step of the auction, to which sellers should those transfers be made (minimal overdemanded sets) is the key...

Arrow's impossibility theorem: Two simple single-profile versions

Feldman, Allan M.; Serrano, Roberto - 2008

In this paper we provide two simple new versions of Arrow's impossibility theorem, in a model with only one preference profile. Both versions are transparent, requiring minimal mathematical sophistication. The first version assumes there are only two people in society, whose preferences are...

Cognitive constraints, contraction consistency, and the satisficing criterion

Tyson, Christopher J. - 2007

A theory of decision making is proposed that offers an axiomatic basis for the notion of satisficing postulated by … Herbert Simon. The theory relaxes the standard assumption that the decision maker always fully perceives his preferences among … be equivalent to abandoning the contraction consistency axiom of classical choice theory. …

Reason-based choice correspondences

Lombardi, Michele - 2007

A reason-based choice correspondence rationalizes choice behaviour in terms of a two-stage choice procedure. Given a feasible set S, the individual eliminates from it all of the dominated alternatives according to her fixed (not necessarily complete) strict preference relation, in the first...

On the role of non-equilibrium focal points as coordination devices

Bosch-Domènech, Antoni; Vriend, Nicolaas J. - 2008

Considering a pure coordination game with a large number of equivalent equilibria, we argue, first, that a focal point that is itself not a Nash equilibrium and is Pareto dominated by all Nash equilibria, may attract the players' choices. Second, we argue that such a non-equilibrium focal point...

Determining the stationarity properties of individual series in panel datasets

Kapetanios, George - 2003

An attractive feature of panel unit root tests is the ability to exploit coefficient homogeneity under the null hypothesis of a unit root for all series in order to obtain a more powerful test of the unit root hypothesis. However, under the alternative hypothesis of heterogeneous panel unit root...
