The paper aims to identify both the major changes that have occurred in the energy sector during the past thirty years and the key driving forces that explain these changes. After a review of the key concepts provided by economic theory in order to analyse technical change in Section 2, Section...

This paper explores various dimensions of the learning process for low-carbon technologies under different mitigation scenarios. It uses the POLES model, which addresses learning as an endogenous phenomenon with learning curves, and a set of scenarios developed as part of the AMPERE project. It...

We do two things in this paper. First, we put forward some elements of a microeconomic theory of technological evolution. This involves adding nascent (essentially undiscovered) technologies to the existing technologies of neoclassical production theory, and, more importantly, expanding the...

The theoretical literature on endogenous growth and international trade suggests that comparative advantage is endogenous. Sector-specific learning by doing and technology transfer respectively provide reasons why initial patterns of international specialization may persist or exhibit mobility...

This paper addresses the impact of endogenous technology through research and development (R&D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with technological change through R&D and the second with LbD. We study the interaction between...

The paper reviews the “stylized facts” on economic growth gathered by Easterly and Levine in their 2001 joint paper and illustrates some of the points made on the basis of data from the IMF’s World Economic Outlook on real growth and per capita GDP since 1970. The data show that the growth...

A growing body of literature suggests that variations across countries, in entrepreneurial activity and the spatial structure of economies could potentially be the source of different efficiencies in knowledge spillovers, and ultimately in economic growth. We develop an empirical model that...

Convergence in per capita income across countries turns on whether technological knowledge spillovers are global or local in a large class of models. This Paper estimates the amount of spillovers from R&D expenditures in major industrialized countries on a geographic basis. A new data set is...
