French firms laying off workers aged 50 and above have to pay a tax to the unemployment insurance system, known as the Delalande tax. This is a rare case of experience rating in the European context. We evaluate its impact on layoffs as well as on hiring, taking advantage of several changes in...

This paper reports the results from an experiment on two-unit sequential auctions with and without a buyer’s option (which gives the winner of the first auction the right to buy the second unit at the winning price). The demand for the two items is either decreasing, flat, or increasing. The 4...

Let, y, a binary outcome, v a continuous explanatory variable and x some other explanatory variables. We study inference on the parameter b of the semiparametric binary regression model y=1(xb+v+e0). We show that the set-up introduced by Lewbel (2000) that is, an uncorrelated-error restriction...

In this paper we extend the "collective" model of labour supply developed by Chiappori (1988) to allow for discrete choices, censoring and nonparticipation in employment. We derive the collective restrictions on labour supply functions that we contrast with restrictions implied by the usual...

This paper surveys the recent theoretical and empirical literature that explores the relations between aid and trade and ask about the complementarity or substitution effects at work. We distinguish between the effects of aid on trade flows and its effect on trade policies, of the donor as well...

We show how differences in aggregate human development outcomes over time and space can be additively decomposed into a pure economic-growth component, a component attributed to differences in the distribution of income, and components attributed to “non-income” factors and differences in...
