This note shows that Lemma 3 in the paper by Tiago N. Sequeira [R&D spillovers in an endogenous growth model with physical capital, human capital and varieties, <italic>Macroeconomic Dynamics</italic> (2011)] is insufficient to guarantee stability and provides an alternative sufficient condition for stability.

In this article we devise an endogenous growth model with R&D, physical capital, and human capital with several externalities. The model is calibrated to the US economy and used to quantitatively evaluate the effect on growth and welfare of implementing different budget-neutral policies. The...

We evaluate the growth and welfare effects of budget-neutral reforms in the US tax system. Large gains in welfare and growth could result from adopting a consumption-based tax system. In contrast, significant welfare and growth losses would follow after implementing an income tax-based reform....

This paper devises an endogenous growth model with physical capital, human capital and product variety. Differently to previous works, innovation is subject to externalities associated to the duplication of research effort, as well as to R&D spillovers. We provide conditions for the existence of...

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 note shows that the competitive equilibrium is efficient in the Uzawa-Lucas endogenous growth model with sector-specific externalities associated to human capital in the goods sector for a large class of goods production technologies.

This paper presents a fertility choice model in which the mortality rate is also endogenously determined and health expenditure provides utility to individuals as well as affects the mortality rate. The analysis shows that the model predictions agree with the empirical evidence on the...

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...
