In this paper, we characterize and empirically implement robust normative criteria for comparing societies on the basis of their allocations of risks among their members. Risks are modelled as lotteries on the set of distributions of state-contingent pecuniary consequences. Individuals are...

This article examines the link between restrictions on the number of physicians and general practitioners’ (GPs) earnings. Using a representative panel of 6016 French self-employed GPs over the years 1983–2004, we estimate an earnings function to identify experience, time and cohort effects....

Simula and Trannoy (2007) have shown that ELIE is confronted with implementation issues when the policymaker cannot observe the time worked by every individual. This paper tries to fix this problem. To this aim, it characterizes the second-best allocations which are the closest to ELIE (i) in...

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 within the household: an individual is systematically disadvantaged in the intra-household allocation. If an improvement of...

This paper analyzes social situations in the context of risk. A new argument is proposed in order to defend the ex-post approach against Diamond’s (1967) famous critique of Harsanyi’s (1955) utilitarian theorem. It leads to a characterization of the criterion consisting in computing the...

This paper examines the normative properties of an empirically implementable dominance criterion for comparing alternative distributions of two attributes, one of which being cardinally measurable, between an arbitrary number of individuals. The criterion, which generalizes the one proposed by...

inequality decreases and welfare increases as a result of a progressive transfer. We explore the implications for welfare and inequality measurement of substituting the weaker absolute differentials and deprivation quasi-orderings for the Lorenz quasi-ordering. Restricting attention to...

The universal moral public good of fighting poverty is provided by both public and private transfers. Efficient public transfers do not crowd out giving because of the particular motives for it. Understanding these effects is necessary for both explaining aid and choosing policy. This analysis...

Xu’s theorem comforts ranking the freedom of choice provided by budget sets as their volume in deriving it from three axioms. Yet, one and a half of these axioms can be discussed. In contrast, simple logic – it seems – leads one to order the freedom provided by budgets sets as the distance...

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...
