We study the development of bargaining behavior in children age seven through 18, using ultimatum and dictator games. We find that bargaining behavior changes substantially with age and that most of this change appears to be related to changes in preferences for fairness, rather than bargaining...

In this study we derive measures of the redistributive effect of taxes and welfare expenditures for the U.S. using CPS data for the years 1994, 1999 and 2004. We find that whilst income inequality increased, the redistributive effect of taxes and public transfers together reduced market income...

Poverty evaluations differ from welfare evaluations in one significant aspect, the existence of a threshold or reference point, the poverty line. It is therefore possible to build up normative evaluation models in which comparisons are made taking distances from this reference point and not only...

We present a new class of social cost-of-living indices and a nonparametric framework for estimating these and other social cost-of- living indices. Common social cost-of-living indices can be understood as aggregator functions of approximations of individual cost-of-living indices. The Consumer...

The purpose of our paper is to derive instructive analytics on how to account for differentials in demographic variables, in particular mortality, when performing welfare comparisons over time. The idea is to apply various ways of ‘correcting’ estimated income distribution measures for...

The paper describes the issue of the impact of poverty and income inequality on the health of the population using Armenia as a case study. In the framework of this paper author provides an overview of research relating to inequalities in health to the disadvantage of the poor, and to changes in...

Du fait du manque de données de panel, il existe peu d’études sur la dynamique de la pauvreté dans les pays en développement. De plus, il est difficile d’en tirer des conclusions générales en raison des différences méthodologiques entre elles. Notre étude sur la dynamique de la...

We use several well-being measures that combine average income with a measure of inequality to undertake intertemporal and global comparisons of well-being. The conclusions emerging from the intertemporal analysis are that the impact of these measures on temporal trends in well-being is...

This is a background note to a joint IPEA/World Bank Report, provisionally entitled "Selected Topics on Income Inequality in Brazil", with publication planned for 2001. The purpose of the note is twofold. First we propose four central questions which the Report should seek to address, and around...

This is an experimental study of a three-player power-to-take game where a proposer is matched with two responders. We compare a treatment in which subjects are anonymous to each other (strangers) with one in which responders know each other from outside the lab (friends). We focus on the...
