In this paper, we extend the Romer (1990) model in two ways. First, we include energy consumption of intermediates. Secondly, intermediates become heterogeneous due to endogenous energy saving technical change. However, aggregate effective capital is still subject to endogenous technical change...

We employ a general purpose technology model with endogenous stochastic growth to simulate the effects of different energy policy schemes. An R&D sector produces endogenous growth by developing radical and incremental technologies. These innovations result in blueprints for capital...

In this paper, the effects of uncertainty and of various policy instruments on the lengthand attractiveness of private research projects are studied. Research expenditure can beregained from quasi-rents that are earned by exploiting patents on the fruits of research.The accumulation of knowledge...

The methods by which fuels can be converted into electricity all belong to different “technology families”: the “gas-fired-turbine-family”, the “coal-fired-turbine-family”, etc. Each family consists of different generations of similar technologies, as in a vintage model. Within a...

This paper deals with the problem of tackling the adverse effect of output growth on environmental quality. For this purpose we use an intermediate sector that builds ‘putty-practically-clay’ capital consisting of an energy-raw capital amalgam used for final goods production. The...

In this paper we present an endogenous growth model based on Lucas (1988). We have extended the Lucas model by incorporating ICT-capital next to human capital. We take account of spillovers from ICT use in human capital formation to final output production. The effects on growth of these...

By formulating an endogenous growth model that combines elements from Romer (1990), Aghion and Howitt (1992), and van Zon and Yetkiner (2003), the present paper studies the contribution of education and training on economic growth through their impact on the rate of innovation. The article...

In this paper, we present a simple endogenous growth model that allows for the occurrence of innovations that can develop into General Purpose Technologies (GPTs), which are the result of basic R&D. The model incorporates the main features of the Romer (1990) model and the Aghion and Howitt...

For a long time economists have tended to ignore health as a relevant factor of production and important determinant of economic growth. The widely observed positive relationship between health expenditures and economic growth was considered the result of a strong positive income effect....
