This paper investigates the relationship between product market competition and innovation. We find strong evidence of an inverted-U relationship using panel data. We develop a model where competition discourages laggard firms from innovating but encourages neck-and-neck firms to innovate....

A model of endogenous growth is developed in which vertical innovations, generated by a competitive research sector, constitute the underlying source of growth. Equilibrium is determined by a forward-looking difference equation, according to which the amount of research in any period depends...

The recent changes in the US wage structure are often linked to the new wave of capital-embodied information technologies. The existing literature has emphasized either the accelerated pace or the skill-bias of embodied technical progress as the driving force behind the rise in wage inequality....

Is more intense product market competition and imitation good or bad for growth? This question is addressed in the context of an endogenous growth model with “step-by-step†innovations, in which technological laggards must first catch up with the leading-edge technology before battling...

How does entry affect productivity growth of incumbents? In this paper we exploit policy reforms in the United Kingdom that changed entry conditions by opening up the U.K. economy during the 1980s and panel data on British establishments to shed light on this question. We show that more entry,...

We introduce imperfect creditor protection in a multicountry Schumpeterian growth model. The theory predicts that any country with more than some critical level of financial development will converge to the growth rate of the world technology frontier, and that all other countries will have a...

In this chapter we argue that the endogenous growth model with quality-improving innovations provides a framework for analyzing the determinants of long-run growth and convergence that is versatile, simple and empirically useful. Versatile, as the same framework can be used to analyze how growth...

Advanced economies have experienced a tremendous increase in material well-being since the industrial revolution. Modern innovations such as personal computers, laser surgery, jet airplanes, and satellite communication have made us rich and transformed the way we live and work. But technological...

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...

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 which could not be properly addressed by alternative theories. In this survey, we focus on...
