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...

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...

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 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....

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...
