Characterization of the anticipated performance of energy technologies to inform policy decisions increasingly relies on expert elicitation. Knowledge about how elicitation design factors impact the probabilistic estimates emerging from these studies is, however, scarce. We focus on nuclear power, a large-scale low-carbon power option, for which future cost estimates are important for the design of […]
The future costs of nuclear power using multiple expert elicitations: effects of RD&D and elicitation design
Going Electric: Expert Survey on the Future of Battery Technologies for Electric Vehicles
The paper describes the results of a survey, carried out with leading EU experts, on the capacity of both fully electric and plug-in hybrid vehicles to reach commercial success in the next twenty years. The success of electric transport is hampered by a combination of low range, scarce efficiency and high costs of batteries. Costs […]
Clean and Dirty International Technology Diffusion
This paper investigates the role of Intellectual Property Rights (IPR) protection and Environmental Policies (EPs) on clean (renewable) and dirty (fossil-based) technology diffusion from top-innovators. IPR protection and EPs are extensively debated policy tools, as IPR protection addresses knowledge market failure, while EPs respond to pressing local and global environmental externalities. A model of monopolistic […]

In this paper we make an explicit effort to collect, harmonize and describe data on power-related R&D from both the public and the private sector for a sample of 16 countries over the years 1995-2007. We focus on the upstream energy sector (power) due to both its’ relevance for energy security concerns and future climate […]
Heterogeneous Firms Trading In Ideas: An Application to Energy Technologies
Notwithstanding the central role attributed to technology transfer (TT) and the effort to promote it through the creation of permanent international bodies such as the Subsidiary Body for Scientific and Technological Advice of the UNFCCC, very little is known about the determinants of this process with respect to energy technologies. This paper marries the literature on international trade […]
Deviations in Kilometres Travelled: The Impact of Different Mobility Futures on Energy Use and Climate Policy
The importance of a focus on mobility and the kilometres travelled using light duty vehicles is reflected in the persistence of strong demand for personal mobility and emissions that tend to be linked with population and economic growth. Simulation results using the WITCH model show that changes in the kilometres driven per year using light […]

Energy intensity developments in 40 major economies: Structural change or technology improvement?
This study analyzes energy intensity trends and drivers in 40 major economies using the WIOD database, a novel harmonized and consistent dataset of input–output table time series accompanied by environmental satellite data.

Ambiguous Aggregation of Expert Opinions: The Case of Optimal R&D Investment
How should a decision-maker allocate R&D funds when a group of experts provides divergent estimates on a technology’s potential effectiveness? To address this question, we propose a simple decision-theoretic framework that takes into account ambiguity over the aggregation of expert opinion and a decision-maker’s attitude towards it. In line with the paper’s focus on R&D […]
Beyond GDP: Modelling Labour Supply as a ‘Free Time’ Trade-off in a Multiregional Optimal Growth Model
In this paper we develop the standard utility function of a Ramsey-type optimal growth model to account for a ‘market-time’ vs. ‘free-time’ trade-off. To do so, we introduce a free-time preference coefficient that measures the utility gained by deviating from a maximum labour supply defined as the combination of a 95% labour force participation rate […]
Advanced Biofuels: Future Perspectives from an Expert Elicitation Survey
This paper illustrates the main results of an expert elicitation survey on advanced (second and third generation) biofuel technologies. The survey focuses on eliciting probabilistic information on the future costs of advanced biofuels and on the potential role of RD&D (Research, Development and Demonstration) efforts in reducing these costs and in supporting the deployment of […]
Migration, Cultural Diversity and Innovation: A European Perspective
This paper analyses the effect of skilled migration on two measures of innovation, patenting and citations of scientific publications, in a panel of 20 European countries. Skilled migrants positively contribute to the knowledge formation in host countries as they add to the pool of skills in destination markets. Moreover, they positively affect natives’ productivity, as […]
Sustainable Cooperation in Global Climate Policy: Specific Formulas and Emission Targets to Build on Copenhagen and Cancun
We offer a framework to assign quantitative allocations of emissions of greenhouse gases (GHGs), across countries, one budget period at a time. Under the two-part plan: (i) China, India, and other developing countries accept targets at Business as Usual (BAU) in the coming budget period, the same period in which the US first agrees to […]
Emissions Pricing to Stabilize Global Climate
In the absence of significant greenhouse gas (GHG) mitigation, many analysts project that atmospheric concentrations of species identified for control in the Kyoto protocol could exceed 1000 ppm (carbon-dioxide-equivalent) by 2100 from the current levels of about 435 ppm. This could lead to global average temperature increases of between 2.5 and 6°C by the end […]
A Good Opening: The Key to Make the Most of Unilateral Climate Action
In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the benefits of cooperation, the incentive to expand the demand of fossil fuels, and the incentive to adopt cleaner technologies introduced […]
The Future Prospect of PV and CSP Solar Technologies: An Expert Elicitation Survey
In this paper we present and discuss the results of an expert elicitation survey on solar technologies. Sixteen leading European experts from the academic world, the private sector and international institutions took part in this expert elicitation survey on Photovoltaic (PV) and Concentrated Solar Power (CSP) technologies. The survey collected probabilistic information on (1) how […]
Incentives and Stability of International Climate Coalitions: an Integrated Assessment
This paper analyses the incentives to participate in and the stability of international climate coalitions. Using the integrated assessment model WITCH, the analysis of coalitions’ profitability and stability is performed under alternative assumptions concerning the pure rate of time preference, the social welfare aggregator and the extent of climate damages. We focus on the profitability, […]

With a focus on alternative methods for accelerating clean energy policy adoption, this study introduces an innovative financing scheme for renewable and energy efficiency deployment. Financing barriers represent a notable obstacle for energy improvements and this is particularly the case for low-income households. Limited access to credit, due to socio-economic status and the lack of […]
What should we expect from innovation? A model-based assessment of the environmental and mitigation cost implications of climate-related R&D
This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and improve the economic efficiency of a mitigation policy package? To answer these questions, we use […]
