Drawing from the formal setting of the optimal tax theory (Mirrlees 1971), the paper identifies the level of Rawlsianism of some European social planner starting from the observation of the real data and redistribution systems and uses it to build a metric that allows measuring the degree of...

The debate over the use of tariffs or value added taxes in developing countries has focused on the difficulty of collecting VAT from the informal sector of the economy. This paper contributes by considering this issue with heterogeneous firms and endogenous entry. This yields two new results....

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 studies how investment tax incentives stimulate output in an estimated medium-scale dynamic stochastic general equilibrium model. We find that the horizon following a positive shock to investment tax incentives is crucial. The shock is highly expansionary in the long run, with the...

This paper studies how investment tax incentives stimulate output in a medium-scale DSGE model, which allows for a variety of fiscal financing mechanisms. We find that the horizon following a positive shock in investment tax incentives is crucial. The shock is highly expansionary in the long...

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...
