Despite numerous studies on labor supply, the size of elasticities is rarely comparable acrosscountries. In this paper, we suggest the first large-scale international comparison ofelasticities, while netting out possible differences due to methods, data selection and theperiod of investigation....

Whether observed differences in redistributive policies across countries are the result ofdifferences in social preferences or efficiency constraints is an important question that pavesthe debate about the optimality of welfare regimes. To shed new light on this question, weestimate labor supply...

By inverting Saez (2002)’s model of optimal income taxation, we characterize theredistributive preferences of the Irish government between 1987 and 2005. The (marginal)social welfare function revealed by this approach is consistently comparable over time andshow great stability despite...

Using counterfactual microsimulations, Shapley decompositions of time change in inequalityand poverty indices make it possible to disentangle and quantify the relative effect of taxbenefitpolicy changes, compared to all other effects including shifts in the distribution ofmarket income. Using...

Discrete-choice models of labor supply have become very popular for ex ante evaluations ofpolicy reforms as they easily account for non-convex budget sets. We test the constraintsimposed in practice on these models and suggest a fully flexible model that significantlyimproves fit....
