The MIT EPPA6 Model: Economic Growth, Energy Use, and Food Consumption

Abstract

The MIT Economic Projection and Policy Analysis (EPPA) model has been broadly applied on energy and climate policy analyses. In this paper, we present our newest model: EPPA6-L. Besides adopting the GTAP8 database as the core economic data, EPPA6-L incorporates the latest energy, emissions, and cost estimates from existing studies, and enhances the model structure and implementation to facilitate future extension. With these improvements, the projected business-asusual CO2 emissions in 2100 are lowered by 6.3% compared to the EPPA5 number. We also present how projections for the consumption of crops, livestock, and food products are improved with nonhomothetic preference, and how various assumptions for business-as-usual GDP growth, elasticity of substitution between energy and non-energy input, and autonomous energy efficiency improvement may change CO2 emissions and prices.
