I study an economy where oligopolistic firms establish in-house R&D programs to produce a continuous flow of cost-reducing (incremental) innovations. The scale of firms' R&D operations determines the rate of productivity growth. I first study the role of concentration, firm size, and demand,...

I develop a growth model in which R&D resources can be directed either to the discovery of new technologies (inventions) or to the improvement of the quality of machines without altering their underlying technology (innovations). Learning-by-doing is an important determinant of the relative...

Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on...

This paper argues that growth theory needs a more general notion of “regularity” than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set...

The European Union has implemented demand push and technology pull policies to foster innovation on the energy and resource efficiency of capital goods. The state of the art of general equilibrium modelling applied to environmental policy rarely treats product and process innovation separately...

We analyze the effects of automation and education on economic growth and inequality in an R&D-based growth model with two types of labor: high-skilled labor that is complementary to machines and low-skilled labor that is a substitute for machines. The model predicts that innovation-driven...
