This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...

The paper considers a climate change growth model with three R&D sectors dedicated to energy, backstop and CCS (Carbon Capture and Storage) efficiency. First, we characterize the set of decentralized equilibria: A particular equilibrium is associated to each vector of public tools which includes...

Conventional wisdom argues that environmental policy is less costly if environmental policy induces the development of cleaner technologies. In contrast to this argument, we show that the cost of environmental policy (a reduction in emissions) may be larger with induced technical change than...

Using data from 11 main manufacturing industries in 17 OECD countries, this paper empirically investigates the determinants of cross-country differences in the persistence of productivity differentials Specifically, we focus on the effects of product market structure and technology diffusion. It...

The catchword 'green skills' has been common parlance in policy circles for a while, yet there is little systematic empirical research to guide public intervention for meeting the demand for skills that will be needed to operate and develop green technology. The present paper proposes a...

Theoretical analysis and empirical evidence show that leadership behavior in climate policy through increased abatement efforts or international transfers cannot be expected to be very successful. In this paper we instead show that pioneering activities, which are based on green technological...

We borrow standard assumptions from the non-renewable-resource-taxation and from the directed-technical-change literatures, to take a full account of the incentives to perform R&D activities in a dirty-resource sector and in a clean-resource-substitute sector. We show that a gradual rise in the...
