We examine the contribution of human capital to economy-wide technological improvements through the two channels of innovation and imitation. We develop a theoretical model showing that skilled labor has a higher growth-enhancing effect closer to the technological frontier under the reasonable...

Evolutionary and environmental economics have a potentially close relationship. This paper reviews past and identifies potential applications of evolutionary concepts and methods to environmental economics. This covers a number of themes: resource use and ecosystem management; growth and...

This paper reviews the emergence and evolution of major topics in economics of innovation. Throughout the paper, particular attention is devoted to the analysis of the cumulative aspects and complementarities between di_erent paths of research over time. Moreover, this survey highlights the...

The benefits from the New Economy should accrue as improvements in productivity and economic growth. But while the use of information and communication technology seems to have had a substantial impact on the performance of the United States economy, the evidence for other countries is much...

This paper presents a theoretical model and empirical evidence to explain the observation that a country in which the level of technology approaches the technology frontier tends to rely more on technology creation than adoption, and to invest more in basic research than in development. The...

We develop a perpetual youth model to investigate how longevity affects economic growth and welfare. Life expectancy is determined by individuals’ investments in healthcare. We find that improvements in the healthcare technology always increase the steady state growth rate. Although the effect...

We apply a stochastic frontier production model to data from 53 countries during 1991-2003 to estimate total factor productivity growth, and decompose it into technical efficiency change and technical progress. Our empirical results indicate that world productivity growth was led by fast-growing...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...
