Are Capital Inflows Expansionary or Contractionary? Theory, Policy Implications, and Some Evidence

Working Papers 15-17


The workhorse open-economy macro model suggests that capital inflows are contractionary because they appreciate the currency and reduce net exports. Emerging-market policymakers, however, believe that inflows lead to credit booms and rising output, and the evidence appears to go their way. To reconcile theory and reality, the authors extend the set of assets included in the Mundell-Fleming model to include both bonds and nonbonds. At a given policy rate, inflows may decrease the rate on nonbonds, reducing the cost of financial intermediation, potentially offsetting the contractionary impact of appreciation. The authors explore the implications theoretically and empirically and find support for the key predictions in the data.
