Generic determinacy and money non-neutrality of international monetary equilibria

Lucas did not find these non-neutral effects in his model of international finance because he postulated a 'sell-all model' in which every agent sells everything he owns in every period. Thus, the number of transactions remain unaffected by definition regardless of any policy changes. Instead, when transactions emerge endogenously in equilibrium monetary policy has non-neutral effects provided that there exist potential gains to trade at the initial allocation of goods.
