We propose a new class of multidimensional poverty indices. Aggregation of the different dimensions relies on individual preferences. The Pareto principle is, therefore, satisfied among the poor. The indices add up individual measures of poverty that are computed as a convex transform of the...

Standard measures of multidimensional inequality (implicitly) assume common preferences for all individuals and, hence, are not sensitive to preference heterogeneity among the members of society. In this paper, we measure the inequality of the distribution of equivalent incomes, which is a...

We study fairness in economies where humans consume one private good and one public good representing the welfare of other species. We show that a social evaluator cannot be egalitarian with respect to humans while always respecting humans' unanimous preferences. One solution is to respect...
