Since the early 1750's economists have elaborate two approaches in order to deal with economic history: a stage theory and a theory of continuing, quantitative growth. J. Schumpeter argued forcibly in favour of the development approach while N. Georgescu-Roegen endorsed the Schumpeterian...

L'objet de cet article est de faire apparaître la singularité des liens qui unissent l'histoire de la pensée économique et la théorie économique. Une première partie met en évidence ce qui est susceptible d'expliquer la pérennité de la recherche historique. L'accent se trouve ainsi...

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...

This paper reviews evidence that energy technologies and systems adapt over time to accomodate external pressures: that technical innovation and systemic change in the energy sector is largely induced by need, and restrained by potentially large transitional costs. A simple integrated model of...

This paper aims to investigate the transition to a new energy system based on hydrogen in the European liberalized framework. After analyzing the literature on the hydrogen infrastructure needs in Europe, we estimate the size and scope of the transition challenge.We take the theoretical...

This paper proposes a model of entrepreneurial turnover highlighting a non-monotone relationship between technological change and ability-biased sorting into entrepreneurial types. Entrepreneurial decisions are examined in a two-stage model under uncertainty in which entrepreneurs decide to...

The present paper examines the meaning and usefulness of the concept of a New Economy. This construct, which first began to appear in the media in the mid-1990s, is utilised today with a variety of definitions and intentions. Having identified three possible denotations or orientations relating...

This paper considers the relationship between the adoption of electronic traceability systems (ETSs) and the organization of firms. More precisely, it analyzes the respective roles of a firm's organizational structure, and organizational changes, in the process of ETS adoption in agribusiness....

There is now ample evidence that jobs and wages have been polarizing at the extremes of the skill distribution since the early 90s. Autor, Levy and Murnane (2003) have suggested that this might be due to technology substituting more easily for labor in performing routine rather than non-routine...

This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield...
