This paper, a companion to NI WP 14-11, describes the structure of, and data sources for, the macroeconomic component of the Dynamic Integrated Economy/Energy/Emissions Model (DIEM), which was developed at the Nicholas Institute for Environmental Policy Solutions at Duke University. The DIEM model includes a macroeconomic, or computable general equilibrium (CGE), component and an electricity component that gives a detailed representation of U.S. regional electricity markets, DIEM-Electricity. The DIEM-CGE component can be run as a stand-alone model to look at both global and U.S. domestic policies related to the economy, energy, or greenhouse gas emissions. Alternatively, DIEM-CGE can be linked to DIEM-Electricity to investigate the macroeconomic impacts of policies affecting electricity generation. This paper describes DIEM-CGE’s model structure, data sources, representations of production technologies, and possible linkages to DIEM-Electricity. It provides an overview of the model and details of the equilibrium structure underlying the model. It presents the production equations and discusses the model’s data and forecast sources. It also presents information on the model’s greenhouse gas emissions and abatement options as well as details of the linkage between DIEM-CGE and DIEM-Electricity.
