The paper concerns a model of influence in which agents make their decisions on a certain issue. We assume that each agent is inclined to make a particular decision, but due to a possible influence of the others, his final decision may be different from his initial inclination. Since in reality...

This paper proposes two related measures of educational inequality: one for educational achievement and another for educational opportunity. The former is the simple variance (or standard deviation) of test scores. It is selected after careful consideration of two measurement issues that have...

What explains people s preferences for state intervention in social policies? Conducting a cross-section analysis on individual-level survey data, we highlight the link between the economic position of agents and their specific demand toward redistribution. Controlling for a number of factors...

In cooperative games, the core is the most popular solution concept, and its properties are well known. In the classical setting of cooperative games, it is generally assumed that all coalitions can form, i.e., they are all feasible. In many situations, this assumption is too strong and one has...

In this paper, we investigate the effect of a change in childcare subsidies on parental subjective well-being. Starting in 1997, the Canadian province of Québec implemented a generous program providing $5-a-day childcare to children under the age of 5. By 2007, the percentage of children...

L'existence d'une discrimination raciale à l'embauche sur le marché du travail est désormais largement documentée dans la plupart des économies occidentales. Si ce phénomène est confirmé par différentes études pour le marché du travail français, les causes et les sources de cette...

Numerous field experiments have demonstrated the existence of discrimination in labor markets against specific minority groups. This paper uses a correspondence test to determine whether this discrimination is due to prejudice against specific groups, or a general preference for the majority...

Traditional indices of bi-dimensional inequality and polarization were developed for cardinal variables and cannot be used to quantify dispersion in ordinal measures of socioeconomic status and health. This paper develops two approaches to the measurement of inequality and bi-polarization using...

We describe a simple computing technique for the tournament choice problem. It rests upon relational modeling and uses the BDD-based computer system RelView for the evaluation of the relation-algebraic expressions that specify the solutions and for the visualization of the computed results. The...

This paper studies the value of private information in strictly competitive interactions in which there is a trade-off between (i) the short-run gain of using information, and (ii) the long-run gain of concealing it. We implement simple examples from the class of zero-sum repeated games with...
