DSGE Modeling at the Fund : Applications and Further Developments

Researchers in policymaking institutions have expended significant effort to develop a new generation of macro models with more rigorous microfoundations. This paper provides a summary of the applications of two of these models. The Global Economy Model is a quarterly model that features a large assortment of nominal and real rigidities, which are necessary to create plausible short-run dynamics. However, because this model is based on a representative-agent paradigm, its Ricardian features make it unsuitable to study many fiscal policy issues. The Global Fiscal Model, which is an annual model that uses an overlapping-generations structure, has been designed to analyze the longer-term consequences of alternative fiscal policies
