The Polish tax and benefit system is presented in the context of a recently developed microsimulation model, SIMPL. The model allows simulating direct taxes, social contributions and public benefits in Poland for the years 2003 and 2005. It is based on the Household Budgets Survey data (Badania...

The current debt crisis has given rise to a debate about deeper fiscal integration in Europe. The view is widespread that moving towards a 'fiscal union' would have a stabilising effect in the event of macroeconomic shocks. In this paper we study the economic effects of introducing two elements...

Natural experiments provide explicit and robust identifying assumptions for the estimation of treatment effects. Yet their use for policy design is often limited by the difficulty in extrapolating on the basis of reduced-form estimates of policy effects. On the contrary, structural models allow...

In this paper, we analyze the impact of a tax policy change on social welfare by using jointly a collective model of household labor supply and a microsimulation program of the French tax-benefit system. The collective approach allows studying the intrahousehold distribution so that for the...

Strict containment limits the spread of pandemics but is difficult to achieve when people must continue to work to avoid poverty. A new role is emerging for income support: by enabling people to effectively stay home, it can produce substantial health externalities. We examine this issue using...

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...

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...
