This article presents a new decomposition of unit labour costs into compensation per worker and labour productivity, which, in turn, is decomposed into e ffciency gains, technical progress and capital deepening. Data for Western European countries and the US show that the evolution of labour...

This study aims at evaluating the actual profile of marginal productivity across the age groups within the workforce. As age-productivity profile might differ between occupations, we differentiate the workforce simultaneously by skills (low-skilled, high-skilled) and by age (young, middle-aged,...

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...

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 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...
