Social assistance and inactivity traps have long been considered as one of the main causes of the poor employment performance of EU countries. The success of New Labour in the UK has triggered a growing interests in instruments capable of combining the promotion of responsibility and...

We assess the effects of U.S. tax policy reforms on inequality by applying a new decomposition method that allows us to disentangle the direct policy effect from the effect of changing market incomes. Over the whole period 1979-2007 the cumulative tax policy effect aggravated income inequality...

Redistributive systems in Africa are still in their infancy but are constantly expanding in order to finance increasing public spending. This paper aims at characterizing the redistributive potential of six African countries: Ghana, Zambia, Mozambique, Tanzania, Ethiopia, and South Africa. These...

Using information on actual ballots rather than survey data, we investigate the impact of immigration on both electoral outcomes and immigrant-related motives underlying political preferences. We take advantage of 94 votes, namely 54 policy propositions and 40 elections for candidates, that took...

Welfare analyses conducted by policy practitioners around the world usually rely on equivalized or per-capita expenditures and ignore the extent of within-household inequality. Recent advances in the estimation of collective models suggest ways to retrieve the complete sharing process within...

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....
