Abstract

The persistent uncertainty about mid-century CO2 emissions targets is likely to affect not only the technological choices that energy-producing firms will make in the future but also their current investment decisions. We illustrate this effect on CO2 price and global energy transition within a MERGE-type general-equilibrium model framework, by considering simple stochastic CO2 policy scenarios. In these scenarios, economic agents know that credible long-run CO2 emissions targets will be set in 2020, with two possible outcomes: either a “hard cap” or a “soft cap”. Each scenario is characterized by the relative probabilities of both possible caps. We derive consistent stochastic trajectories—with two branches after 2020—for prices and quantities of energy commodities and CO2 emissions permits. The impact of uncertain long-run CO2 emissions targets on prices and technological trajectories is discussed. In addition, a simple marginal approach allows us to analyze the Hotelling rule with risk premia observed for certain scenarios.

Previously, he was an economist at the Organisation for Economic Co-operation and Development (OECD) and at the International Energy Agency (IEA) in Paris where his activities covered macroeconomic policy analysis and applied general equilibrium modeling. He contributed to various modeling studies on the assessment of the macroeconomic, environmental and distributional consequences of energy and environmental policies. He also worked on the land-water-energy nexus and on the economic consequences of air pollution. Before he joined the OECD, Olivier worked at ENGIE, in Paris, where he developed an in-house modeling framework for quantifying global long-term energy-economy scenarios. While completing his Ph.D., he was a research assistant at the Center for Operations Research and Econometrics (CORE) in Louvain-la-Neuve, Belgium.

From October 2018 to March 2019, he was KAPSARC's interim vice president of research. Axel joined KAPSARC in 2011, after spending 15 years at IFP Energies Nouvelles in France, where he led research, consulting and training projects. Axel received his Ph.D. in economics from the Pantheon-Sorbonne University in Paris. He undertakes applied research that combines methodological innovation with practical relevance for policymaking. His research is focused on energy economics, policy, finance, oil pricing, and energy-exporting economies. Axel has been published extensively, with over 40 peer-reviewed journal papers to his name.
