For policy makers and analysts, it is important to isolate the redistributive impact of tax-benefit policy changes from changes in the environment in which policies operate. When actual reforms are motivated by work incentives, it is also crucial to evaluate behavioural responses and the...

We assess the effects of U.S. tax policy reforms on inequality by applying a new decomposition method that allows us to disentangle mechanical effects due to changes in pre-tax incomes from direct effects of policy reforms. While tax reforms implemented under Democrat administrations, in...

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

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...

We assess the effects of U.S. tax policy reforms on inequality by applying a new decomposition method allowing us to disentangle the policy effect from changing market incomes. Over the period 1979-2007, the cumulative policy effect aggravated inequality by increasing the income share of the top...

Using counterfactual microsimulations, Shapley decompositions of time change in inequality and poverty indices make it possible to disentangle and quantify the relative effect of tax-benefit policy changes, compared to all other effects including shifts in the distribution of market income....

This paper examines the impact on inequality and poverty of the economic crisis in four European countries, namely France, Germany, the UK and Ireland, and the contribution of tax and benefit policy changes. The period examined, 2008 to 2010, was one of great economic turmoil, yet it is unclear...
