Incorporating different endogenous learning formulations in MERGE

Abstract

This paper presents the implementation of endogenous technological change, following either a one-factor or a two-factor learning curve, in the MERGE model. We have indeed developed a new version of this model, called MERGE-ETL, to analyse the dynamics of endogenous technological learning (ETL) in the energy system. This paper describes first the basic formulation of MERGE-ETL, then the solving techniques used for this model, and presents finally some numerical results in the context of policies designed to mitigate a global climate change.carbon control policies; endogenous technological change; MERGE; optimisation techniques.
