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...

The empirical evidence of a non-monotone relation between income and obesity is not well explained. We build a theoretical model combining income inequality and social comparisons to explain the link between income and obesity and study tax policy implications for fighting obesity. We assume...

Junk-food taxes have had mixed effects on obesity and junk-food consumption. We build a theoretical model to explain those empirical results and better understand how to address the obesity crisis. In our framework, hand-to-mouth consumer's make an intertemporal choice between food consumption...

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...

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...

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...
