This paper proposes a dominance approach to study well-being inequality across countries at the world level. We consider a class of well-being indices based on the three attributes considered in the HDI (Human Development Index). Indices are required to satisfy preference for egalitarian...

Under perfect observation of incomes, designing such scheme boils down to solving an optimisation program under constraints, which can be achieved with well-defined methods. In contrast, when incomes cannot be perfectly observed, the schemes are usually based on predictions of living standards...

We draw some lessons from the Tunisian experience of social reforms and associated unrest. Our main interest is the riots that occurred after subsidy cuts and the attempts at substitution of price subsidies by direct cash transfers. We propose new welfare indicators to assess reforms in such...

This paper analytically investigates the incentive scheme of perpetrators of violent conflicts. It provides a rational equilibrium framework to elicit how monetary incentives and survival considerations shape a combatant’s decision to participate in a conflict. In the model, a leader decides...

This paper addresses the impact of violent conflict on social capital, as measured by citizen anticipation in community groups defined for four activity types: governance, social service, infrastructure development and risk-sharing. Combining household panel data from Indonesia with conflict...

This paper introduces a new methodology to target direct transfers against poverty. Our method is based on observable correlates and on estimation methods that focus on the poor. Using data from Tunisia, we estimate ÔfocusedÕ transfer schemes that improve anti-poverty targeting performances....

Nous montrons à l’aide de l’enquête Logement que les personnes d’origine africaine sont surreprésentées dans les grandes agglomérations et tendent à s’y fixer dans des proportions beaucoup plus importantes que les personnes d’origine française. Deux raisons expliquent ce...

This paper examines how allowing individuals to emigrate to pay lower taxes changes the optimal non-linear income tax scheme in a Mirrleesian economy. Type-dependent participation constraints are borrowed from contract theory. An individual emigrates if his domestic utility is less than his...

We offer a model of equality of opportunity that encompasses different conceptions expressed in the public and philosophical debates. In addition to circumstances whose effect on outcome should be compensated and effort which represents a legitimate source of inequality, we introduce a third...

Consider an income distribution among households of the same size in which individuals, equally needy from the point of view of an ethical observer, are treated unfairly. Individuals are split into two types, the dominant and the dominated. We look for conditions under which welfare and...
