Energy-economy analysis: Linking the macroeconomic and systems engineering approaches

Informal linking or softlinking of macroeconomic and systems engineering models can provide high variety tools for joint energy-economy analysis. A necessary condition for internal control of such linking is a common, formalized language describing areas of overlap between the models. The principle of a common language is discussed and demonstrated for the softlinking of a macroeconomic model (ETA-MACRO) and a systems engineering model (MESSAGE III).
