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...

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...
