In this paper, we estimate a collective model of household labour supply à la Chiappori on British two-earner couples, using data from the British Household Panel Survey (BHPS). We find that family members do not pool their resources: the unitary model is rejected. We estimate a sharing rule...

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 characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

This article discusses the properties of Kolm’s ELIE proposal in the Context of optimal income taxation “à la Mirrlees”. It first shows that ELIE gives rise to non-standard type-dependent budget sets, which has important implications in terms of a minimum labour requirement. Second, it...

It is well-known that the unemployment rate differential between people of foreign and French origins has increased over the past decades. This statement must be completed by two key features. First, the unemployment rate differential is considerably higher in large cities than in small ones....

This paper provides a robust normative evaluation of the spectacular growth episode that India has experienced in the last 15 years. Specifically, the paper compares the evolution, between 1998, 1996 and 2001 of the distribution of several important individual attributes on the basis of...

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...

We provide an axiomatic characterization of a family of criteria for ranking completely uncertain decisions. A completely uncertain decision is described by the set of all its consequences (assumed to be finite). Each of the criterions characterized can be thought of as assigning to all...
