This paper investigates optimal capital taxation in an innovation-driven growth model. We examine how the optimal capital tax rate varies with externalities associated with R&D and innovation. Our results show that the optimal capital tax rate is higher when (i) the "stepping on toes effect" is...

The aim of this paper is to analyse the relationship between competition and growth in an endogenous growth model with expanding product variety without scale effect. In order to do this, we develop an extension of the Bucci (2005) model in which we eliminate the scale effects. We find that the...

In this paper, we extend the Romer90 model by introducing an embodied technological change and by removing the scale effects. We show that this model can still generate steady state growth in which the embodied technical change has an positive and permanent effect on growth in the long-run.

In this note, we explore the implications of cultural preference for education in an innovation-driven growth model that features an interaction between endogenous human capital accumulation and technological progress. Parents invest in children's education partly due to the preference for their...

This paper investigates how the ability to innovate affects firms' decisions to operate informally and the aggregate consequences of their sectoral choice. I embed a sectoral choice model, where firms choose to operate in the formal or informal economy, into a richer general equilibrium...

The aim of this paper is to analyze the relationship between competition and growth in a model of human capital accumulation and research by disentangling the monopolistic mark-up in the intermediate goods sector and the returns to specialization in order to have a better measure of competition....

In this paper, we analyze the long-term impact of an environmental policy on economic growth, pollution and welfare. A standard growth model with horizontal innovation is modified by including pollution which comes from the use of intermediate goods production. Taxation on pollution reduces...

This paper investigates optimal capital taxation in an innovation-driven growth model. We examine how the optimal capital tax rate varies with externalities associated with R&D and innovation. Our results show that the optimal capital tax rate is higher when (i) the "stepping on toes effect" is...

This paper develops an endogenous growth model based on the idea of new combinations of input factors as a growth mechanism. The model integrates the idea of several technologies used simultaneously in producing final output. Innovations are of the horizontal and vertical type and in addition of...

We formulate a model that explicitly separates two functions in the innovation process: The introduction of new goods and the quality improvement of existing goods. While the latter is performed by the corporate R&D sector, the first is performed by entrepreneurs. We show that in a three sector...
