Model information
Institution Fondazione Eni Enrico Mattei (FEEM), Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC)
Concept Hybrid: Economic optimal growth model, including a bottom-up energy sector and a simple climate model, embedded in a `game theory` framework.
Solution method Regional growth models solved by non-linear optimization and game theoretic setup solved by tatonnement algorithm (cooperative solution: Negishi welfare aggregation, non-cooperative solution: Nash equilibrium)
Anticipation Perfect foresight

The WITCH model represents the black carbon (BC), carbon monoxide (CO), ammoniac (NH3), nitrogen oxides (NOx), organic carbon (OC), sulfur dioxide (SO2), volatile organic compounds (VOCs).

The energy-related emissions are computed from the sectoral activities with the appropriate coefficients. The others emissions are exogenous and are issued from the RCP emissions profiles.
