Abstract
In this paper we investigate the long-run economic consequences of phasing out nuclear energy in the presence of stringent climate policies. We integrate endogenous growth theory and technology-based activity analysis into a dynamic numerical general equilibrium model. Both market-based and policy-mandated nuclear phase-out are studied. Using data from the Swiss economy we find that the aggregate welfare loss of carbon policy is as large as 1.21% and that nuclear phase-out raises the loss to 1.58%. Nuclear phase-out has no significant effect on economic growth. Increased investment, induced innovation, and sectoral change are the reasons that the economic impact of nuclear phase-out and the trade-off between energy and climate policy are moderate, once the dynamics of an economy are taken into account. Optimal phase-out time for nuclear depends mainly on future cost escalation in the energy sector.
