Consider the Mundell-Fleming model. C =a+ b(Y - T) - cr I =io - ur Ma =co+ qY - cor G =GT =T M s = M P P =1 X =xo+myf -x2-P Z =zo+ ZY - zzepf F =fot fi(r -rf ) (a) Derive the value of income that simultaneously balances the goods & services and money markets. Denote this value as Y*. (b) Discuss how Y* varies with an appreciation of the US dollar. (Note: ignore the changes that are associated with the BoP.)
