In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We present a Schumpterian model of endogenous growth with General Purpose Technologies (GPTs) that captures two important historical stylized facts: First, from the beginning of mankind until today GPTs are arriving at an increasing frequency and, second, all GPTs heavily depended on previous...

This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. A temporary Northern...

This paper accounts for China's economic growth since 1980 in a unified endogenous growth model in which a sequencing of physical capital accumulation, human capital accumulation and innovation drives the rise in China's aggregate income. The first stage is characterized by physical capital...

We construct a two-sector growth model to show that sector biased technical change is the only fundamental driving force of perpetual structural change and non-balanced sectoral growth. The direction of sector biased technical change depends exclusively on the sectoral difference in the purely...

We construct a two-sector semi-endogenous growth model to investigate the mechanism of sector biased technical change and identify the fundamental driving force of structural change. We find that the balanced sectoral growth will be inevitable, in which structural change could not take place in...

This paper investigates the effect of human capital accumulation on the direction of technical Change in a framework with natural resources and environmental externalities. The model simulates that an increasing knowledge stock of worker tends to direct technical change in favour of intangible...

The determinants of the direction of technical change and their implications for economic growth and economic policy are studied in the one-sector neoclassical growth model of Ramsey, Cass, and Koopmans extended to allow for endogenous capital-and labor-augmenting technical change. We develop a...

The present paper takes a geometric approach to characterize the competitive forces behind innovation and dynamic general equilibria determination in the model of growth through creative destruction constructed by Aghion and Howitt (1992). All the essentials can be comprehended intuitively from...

In this paper we argue that government spending played a significant role in stimulating the wave of innovation that hit the U.S. economy in the late 1970s and in the 1980s, as well as the simultaneous increase in inequality and in education attainments. Since the late 1970s U.S. policy makers...
