Technological Distance, Growth and Scale Effects

Growth without Scale Effects

Technological Complexity and Economic Growth

The last fifty years have witnessed large secular increases in educational attainment and R&D intensity. The fact that these trends have not stimulated more rapid income growth has been a persistent puzzle for growth theorists. We construct a model of endogenous economic growth in which income growth, R&D intensity, and educational attainment depend on the complexity of new technologies. An inc...

Growth, Development, and Technological Change

Growth, Development, and Technological Change The theory of endogenous technical change has deeply contributed to our understanding of the fundamental sources of economic growth and development. In this chapter we survey important contributions in the field by focussing on the basic structure of endogenous growth models with horizontal as well as vertical innovation and emphasizing important im...

Technological Breakthroughs and Productivity Growth

This study consists of an examination of productivity growth following three major technological breakthroughs: the steam power revolution, electrification and the ICT revolution. The distinction between sectors producing and sectors using the new technology is emphasized. A major finding for all breakthroughs is that there is a long lag from the time of the original invention until a substanti...

Technological Growth and Asset Pricing

In this paper we study the implications of general-purpose technological growth for asset prices. The model features two types of shocks: “small”, frequent, and disembodied shocks to productivity and “large” technological innovations, which are embodied into new vintages of the capital stock. While the former affect the economy on impact, the latter affect the economy with lags, since firms nee...
