Levy Economics Institute – The State of the US and World Economie

“This program’s central focus is the use of Levy Institute macroeconomic models in generating strategic analyses of the US and world economies. The outcomes of alternative scenarios are projected and analyzed, with the results—published as Strategic Analysis reports—serving to help policymakers understand the implications of various policy options. The Levy Institute macroeconomic models, created by Distinguished Scholar Wynne Godley, are accounting based. The US model employs a complete and consistent system (in that all sectors “sum up,” with no unaccounted leakages) of stocks and flows (such as income, production, and wealth). The world model is a “closed” system, in which 11 trading blocs—of which the United States, China, Japan, and Western Europe are four—are represented. This model is based on a matrix in which each bloc’s imports are described in terms of exports from the other 10 blocs. From this information, and using alternative assumptions (e.g., growth rates, trade shares, and energy demands and supplies), trends are identified and patterns of trade and production analyzed.

The projections derived from the models are not presented as short-term forecasts. The aim is to display, based on analysis of the recent past, what it seems reasonable to expect if current trends, policies, and relationships continue. To inform policy, it is not necessary to establish that a particular projection will come to pass, but only that it is something that must be given serious consideration as a possibility. The usefulness of such analyses is strategic: they can serve to warn policymakers of potential dangers and serve as a guide to policy instruments that are available, or should be made available, to deal with those dangers, should they arise.”
