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 effect of environmental taxation are not limited to the traditional negative crowding-out and positive productivity effects. We...

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...

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...

This paper contributes to explaining the obesity epidemic and finding a potential remedy. We build a theoretical model of food consumption decisions that accounts for social influence. In our model, individuals' rationality is affected by an endogenous social weight norm, which influences their...

We build a theoretical model to explain the complex patterns of income and obesity, accounting for changes in behavior related to exercise. We combine the theory of time allocation with the theory of conspicuous leisure in a growth model, assuming that consumption expenditures connected to...
