In this paper, we analyze the social planner solution of an endogenous growth model with physical capital, human capital and R&D. The model incorporates three sources of inefficiency: monopolistic competition in the intermediate-goods sector, duplication externalities and spillovers in R&D. A...

This paper analyzes the equilibrium dynamics in a class of one-sector endogenous growth models with external habits. Using an explicit solution expressed in terms of the Gauss hypergeometric function, we show that the levels of consumption, habits and capital may exhibit non-monotonic transition...

The government temporal horizon is shown to be a key determinant of the optimal tax structure in an endogenous growth model of the US economy. As the temporal horizon lengthens, wage taxation is gradually substituted by consumption taxation. The optimal tax mix depends notably on the leisure...

This paper devises a fiscal policy by means of which the first-best optimum equilibrium is attained as a market equilibrium in the Uzawa-Lucas model when average human capital has an external effect on productivity. The optimal policy requires the use of a subsidy to investment in human capital...

This paper quantifies the welfare cost of consumption externalities in an endogenous growth model with habit formation. Agent’s utility depends on both current consumption and a reference consumption level determined by economy-wide average past consumption. Although utility may be lower in...
