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...

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...

I study the transitional welfare effects of a budget neutral reform in a small open economy with overlapping generations and age-dependent mortality. The reform eliminates the capital income tax and replaces it with a consumption tax. I simulate the model for Chile and calculate lifetime welfare...

Within the Blanchard [Blanchard, O., 1985. Debt, Deficits and Finite Horizons. Journal of Political Economy 93 (2), 223–247] model, we determine optimal capital and labor income taxation. We discuss the conditions for non-zero capital income taxation in the long term. We make explicit the...

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...
