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....

Earning an income is probably the best way of avoiding poverty and social exclusion, hence the recent trend of promoting employment through in-work transfers in OECD countries. Yet, the relative consensus on the need for 'making work pay' policies is muddied by a number of concerns relative to...

To assess the impact of tax-bene?t policy changes on income distribution over time, we suggest a methodology based on counterfactual simulations. We start by decomposing changes in inequal- ity/poverty indices into three contributions: reforms of the tax-bene?t structure (rules, rates, etc.),...
