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). �"ʌ3B`m�(#�B*WRg$])��4NA�� ^Ḃ�&�1�#���EBr��ŽR*��~��H�Z��G��A8e9
