Designed to rival structural macroeconometric models—by satisfying the Lu-cas critique (Lucas 1976)—DSGE models have proliferated in the profession, even serving When the Federal Reserve Board developed and considered replacing its existing open economy model, FRB Global (see Brayton et al., 1997), with an open economy New Keynesian DSGE model, a key step was to relate and explain any deviations of the effects of a broad set of shocks in the DSGE from the existing model (see Erceg et al., 2006). † References in the notes refer to articles given on the reading list. 29 0 obj 34 0 obj outcomes makes the models dynamic and assigns a central role to agents’ expectations in the determination of current macroeconomic outcomes.
