I propose a new overlapping generations model, in which individuals face different income levels, life expectancies and borrowing constraints to study Ramsey optimal taxation. Contrary to previous contributions, I find that optimal capital income taxation generally differs from zero in the long...

The author studies age-dependent optimal taxation in an environment that takes into consideration changes in consumption behavior over the life cycle due to changes in labor income paths and borrowing limits. Income mobility is defined as an exogenous rate at which individuals change from a...

We build a model that takes into consideration the evolution of health over the life cycle and its consequences on individual optimal choices. In this framework, the effects of environmental taxation are not limited to the traditional negative crowding-out and positive productivity effects. We...

In a new model with incomplete markets, I quantitatively determine tax reforms that are welfare improving, distributionally neutral, and leave the budget balance unchanged in the long run. I consider a new reform. I eliminate capital income taxation and replace it with progressive consumption...

We revisit the influence of environmental policy on economic activity taking into account the impact of pollution on morbidity and its effect on the labor productivity age-profile. We find that the negative effect of environmental policy on the standard of living is modified by two opposite...
