A suitable strategy for achieving sustainable development is to foster environmental innovations. Environmental innovations, however, suffer from so-called "double externalities", because apart from innovation spillovers they also improve the quality of public environmental goods, which can be...

We develop an economic partial equilibrium model for energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. Our model reproduces the learning curve typical for (bottom-up) energy system...

Environmental policy instruments have an impact on the incentives to invest in environmental R&D and this link should deserve careful consideration when introducing new instruments. Some authors argue that environmental taxes and tradable permits have rather comparable impacts on environmental...

We develop an economic model for fossil-fuel and carbon-free energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. We use the model to study inter-temporally efficient carbon taxes for...

The paper examines the determinants that influence the environmental innovation behaviour of companies in Germany in a multivariate context by using data from the Mannheimer Innovations Panel 1993, which was part of the Community Innovation Survey. The objective is to analyse the general...

Over the past century, all OECD countries have been characterized by a dramatic increase in economic conditions, life expectancy and educational attainment. This paper provides a positive theory that explains how an economy might evolve when the longevity of its citizens both influences and is...

This paper examines the effect of competition on the irreversible investment decisions under uncertainty as a generalization of the “real option” approach. We examine this issue with reference to an industry where each firm has only one investment opportunity which is completely irreversible...

The paper addresses the dynamic-incentive effect of environmental policy instruments when innovation is uncertain and occurs in very complex industrial subsystems. The case of end-of-life vehicles (ELVs) is considered focusing predominantly on the effects of the European Directive adopted in...

This paper investigates the connection between resource abundance and innovation, as a transmission mechanism that can elucidate part of the resource curse hypothesis; i.e. the observed negative impact of resource wealth on income growth. We develop a variation of the Ramsey-Cass-Koopmans model...

The problems about diversity concern various themes. We will show that the economic theory can contribute by itself to the debate in progress. It could seem paradoxical, but what is called the “dismal science” can serve to attenuate some pessimistic attitudes, putting in prominence a...
