3. a, Use the mathematical expression for eqm Y for an open economy (Y= C+ I+ G + X - IM) to explain what it means when a country is running a trade-balance deficit; that is, its IM> its X. b. Use the expression for Y from the two ways (definitions or formulas) of thinking about Yp. Set this expression for Y equal to that from part a. Then derive the twin-deficit identity and explain what it means for the US, which typically runs trade-balance deficits
