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....

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...

Macro-level changes can have substantial effects on the distribution of resources at the household level. While it is possible to speculate about which groups are likely to be hardesthit, detailed distributional studies are still largely backward-looking. This paper suggests a straightforward...

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...

Using a collective model of consumption, we characterize optimal commodity taxes aimed at targeting specific individuals within the household. The main message is that distortionary indirect taxation can circumvent the agency problem of the household. Essentially, taxation should discourage less...

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...

The literature on household behavior contains hardly any empirical research on the within-household distributional effect of tax-benefit policies. We simulate this effect in the framework of a collective model of labor supply when shifting from a joint to an individual taxation system in France....

The non take-up of social assistance bene?ts due to claim costs may seriously limit the anti-poverty eÞect of these programs. Yet, available evidence is fragmented and mostly relies on interview-based data, potentially biased by misreporting and measurement errors on both bene?t entitlement and...
