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....

To assess the impact of tax-benefit policy changes on income distribution over time, wesuggest a methodology based on counterfactual simulations. We start by decomposingchanges in inequality/poverty indices into three contributions: reforms of the tax-benefitstructure (rules, rates, etc.),...

The Polish tax and benefit system is presented in the context of a recently developedmicrosimulation model, SIMPL. The model allows simulating direct taxes, social contributionsand public benefits in Poland for the years 2003 and 2005...>br>

This paper is one of the first comprehensive attempts to compare earnings in urban China and India over the recent period. While both economies have grown considerably, we illustrate significant cross-country differences in wage growth since the late 1980s. For this purpose, we make use of...
