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...

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...

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...

The optimal flat-rate fiscal structure is calculated in a two-sector endogenous growth model of the Mexican economy. Government expenditures would be financed by an income tax rate. If capital and labor income can be taxed at distinct rates, the optimal tax rate on wages would be zero. Holding...
