We look at a model where countries of di fferent size provide local public goods with positive spillovers. Matching grants can induce socially-e fficient expenditure levels, but countries can induce bailouts. We consider the characteristics of these bailouts in a subgame-perfect Nash equilibrium...

This article investigates a tax competition model where countries compete for capital and profits of multinational enterprises (MNEs) through statutory tax rates and cross-border loss-offset provisions, which allow a transfer of foreign subsidiaries’ losses to the parent company. A joint...

We analyze individuals with heterogeneous time-inconsistent preferences that consume sin goods and make a savings decision. A government may tax the sin good and provide mandatory health insurance. Due to time-inconsistency, the individual sin good and savings choices in ict internalities. Due...

This paper shows that if an individual’s health costs are U-shaped in weight with a minimum at some healthy weight level and if the individual has both self control problems and rational motives for over- or underweight, the optimal paternalistic tax on unhealthy food mitigates the...

We analyze how a sales tax levied on all food products impacts the consumption of healthy food, unhealthy food, and obesity. The sales tax can stimulate the consumption of healthy meals by lowering the time costs of food preparation. Moreover, the sales tax lowers obesity under more general...

This study examines whether taxes on unhealthy food are suitable for internalizing intergenerational externalities inflicted by parents when they decide on their children's diet. In an overlapping generations (OLG) model with an imperfectly altruistic parent, the optimal steady-state tax rate on...

This paper develops a new sufficient statistic approach for estimating the marginal internality from sin good consumption. It models a biased consumer who faces uncertain health harms and receives mandatory health insurance. I show that the marginal internality can be identified by observing how...

This paper addresses the question whether taxes on unhealthy food are suitable for internalizing intergenerational externalities inflicted by parents when they decide on their children’s diet. Within an OLG model with an imperfectly altruistic parent, the optimal steady state tax rate on...
