Using data on 135 countries, this paper studies the determinants of process innovation introduction, focusing on the impacts of economic and political uncertainties. Greater uncertainty, on the one hand, can lower potential benefits from innovation introductions, while on the other hand, the...

Whereas various drivers of the international innovative activity have been studied in the literature, our understanding of the contributions of different innovation linkages to innovation deserves more attention. Are the different innovation linkages equally complementary to research inputs in...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed...

We analyse an economy where managers engage both in the adoption of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more...

This paper studies the conditions under which the scarcity of a factor (in particular, labor) encourages technological progress and technology adoption. In standard endogenous growth models, which feature a strong scale effect, an increase in the supply of labor encourages technological...
