WITCH is an energy-economy-climate model developed by the climate change group at FEEM. The model has been extensively … with a representation of the energy sector of medium complexity. Two distinguishing features of the WITCH model are the … representation of endogenous technological change and the game-theoretic set-up. Technological change is driven by innovation and …

neoclassical optimal growth structure (top down) and a detailed energy input component (bottom up). The model endogenously accounts … detailed information on the evolution of energy demand, technology and CO2 emissions. We also explain the procedure used to …

interventions on final-use energy consumption, an important driver of carbon emissions. In the model, energy demand is driven by … directed technical change. Energy supply is subject to increasing extraction costs. The model is consistent with aggregate … evidence on energy use, efficiency, and prices in the United States, as well as the standard balanced growth facts. I use the …

The need for a better understanding of future energy scenarios, of their compatibility with the objective of … optimal growth model (TD) with energy input detail (BU). The model endogenously accounts for technological progress, both …
