We develop a growth model that features the endogenous two-tier innovations of information carrier technology and production technology. Information carrier technology promotes production technology innovation and thus economic growth through improving the preservation and dissemination of...

Over the coming century, computer technology is likely to become capable of reproducing a large portion of the tasks performed by human labor. This paper develops a model of the aggregate economic growth that results when work tasks are transferred from humans to physical capital. The model...

This paper investigates the growth impact of Information and Communication Technologies (ICT) in an economy consisting of three sectors: ICT-producing, ICT-using, and non-ICT-using. The ICT progress causes falling prices of the consumption and intermediates produced by the ICT-using sector,...

How does population aging affect economic growth and factor shares in times of increasingly automatable production processes? The present paper addresses this question in a new macroeconomic model of automation where competitive firms perform tasks to produce output. Tasks require labor and...

At least since 1870 hours worked per worker declined and real wages increased in many of today's industrialized countries. The dual nature of technological progress in conjunction with a consumption-leisure complementarity explains these stylized facts. Technological progress drives real wages...

We analyze the economic growth effects of rising longevity in a framework of endogenous growth driven by quality-improving innovations. We show that a rise in longevity raises savings and thereby reduces the market interest rate. Since the monopoly profits generated by a successful innovation...

We propose an overlapping generations framework in which life expectancyis determined endogenously by governmental health investments. As a novelty, we are able to examine the feedback effects between life expectancy and R&D-driven economic growth for the transitional dynamics. We find that i)...

We analyze the steady state and transitional dynamics of two-sector model with structural change and horizontal innovation. There are three main economic forces could drive structural change: technological progress in one sector, technological progress in the other sector, and capital deepening....

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...
