In this paper, we will review the literature on technological innovation persistence and provide a general theoretical framework to analyze the main determinants of this innovative behavior. Moreover, no previous empirical study has taken into account organizational innovation practices as...

We consider an optimal growth model of an economy facing an exogenous pollution quota. In the absence of an international market of pollution permits, the economy has three instruments to reach sustainable growth: R&D to develop cleaner technologies, investment in new clean capital goods, and...

Geoengineering, i.e. the use of artificial techniques aiming at cooling the planet, is increasingly considered as a realistic alternative to emission mitigation. Several methods are promising for their capacity to quickly halt global warming at a moderate cost. Such cheap technologies might be...

This paper proposes a model in the spirit of Aghion and al. (2005) that relates the magnitude of the impact of competition on R&D to the cost of innovation. The effect of competition on R&D is an inverted U-shape. However, the shape is flatter and competition policy is therefore less relevant...

The aim of this paper is to understand whether international trade may enhance innovation and growth through an increase in competition.We develop a two-country endogenous growth model, both countries producing the same set of goods, with firm specific R&D and a continuum of oligopolistic...

The creative intelligence lies in the framework of the "intelligent" way which must be used to assure creativity and, thus, innovation. As its name suggests, the creative intelligence excludes imitation. Therefore, firstly, it requires an important R&D investment that manifests itself in the...

R&D and innovation have become much more strategic than ever before for the growth of China as well as for its global societal upgrade. The Chinese authorities have designed an innovation strategy to face new economic and social challenges. The first part of the paper is focused on the emergence...

In this note we reconsider the paper of Brod and Shivakumar (1999), published in the Journal of Industrial Economics, who analyze a twostage model in which the firms compete in two dimensions and examine the effect of semi-collusion when the non-production activity is R&D. They shed light on...

European Biotechnology companies and public policy-makers face to a number of crucial problems related to the development of Biotechnology in Europe : European industrial competitiveness, the relative under-exploitation of the European science base in Biotechnology, poor technology transfer...

This paper analyses the potentially defensive behaviour of successful innovators and its effect on aggregate R&D effort. It proposes a quality-ladders model that endogenously determines leader's technology advantages and who innovate (the leader firm or its competitors). Regulation can have...
