%A C.-O. Wene %J Energy %T Energy-Economy-Analysis. Linking the Macroeconomic and Systems Engineering Approaches %X Informal linking or softlinking of macroeconomic and systems engineering models can provide a large variety of 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 common language is discussed and demonstrated for the softlinking of a macroeconomic model (ETA-MACRO) and a systems engineering model (MESSAGE III). %N 9 %P 809-824 %V 21 %C IIASA, Laxenburg, Austria %D 1996 %I RR-96-017.
