International Economics By Robert J. Carbaugh 8th Edition Chapter 17: Macroeconomic Policy in an Open Economy Copyright ©2002, South-Western College Publishing Open economy macro policy Policy in an open economy Countries which are open to the world economy cannot make domestic economic policy choices without considering the impact on trade and payments and their international relationships Nor can open economies entirely insulate themselves from other countries’ policy choices As a result, nations make efforts to coordinate their international economic policies Economic policies are also subject to domestic and foreign institutional constraints Carbaugh, Chap. 17 2 Open economy macro policy Economic objectives Internal balance Fully employed economy Little or no inflation External balance Current account is close enough to balance that foreign debts can be repaid (deficit) or that other nations can repay their debts (surplus) Carbaugh, Chap. 17 3 Open economy macro policy Policy instruments Expenditure-changing policies: alter aggregate demand for goods fiscal policy Monetary policy Expenditure-switching policies: shift demand to/from imports or domestic goods Devaluation or revaluation (fixed rates) Exchange market intervention (managed float) Direct controls Tariffs, quotas, subsidies, capital controls Carbaugh, Chap. 17 4 Open economy macro policy Economic objectives and macro policy Carbaugh, Chap. 17 5 Open economy macro policy Exchange rate policies & overall balance If a nation was experiencing recession and a BOP deficit, a currency devaluation would encourage exports and help boost domestic production If it were experiencing inflation and a BOP surplus, a revaluation would cut back on exports and cool domestic spending Carbaugh, Chap. 17 6 Open economy macro policy Exchange rate & overall balance (cont’d) Such policy moves are not made in a vacuum; one country’s devaluation effectively means a revaluation for its main trading partners If done without international consultation, these policy shifts might invite retaliation (as occurred during the Great Depression) Carbaugh, Chap. 17 7 Open economy macro policy Fiscal & monetary policy: internal effects Fiscal and monetary policy are generally used to achieve internal balance, but their effectiveness depends on the external sector Under a fixed exchange rate system, fiscal policy is more successful in promoting internal balance than is monetary policy Under a floating rate system, monetary policy is more effective than fiscal policy at achieving internal balance Carbaugh, Chap. 17 8 Open economy macro policy Fiscal policy: short run internal effects Under fixed exchange rates Aggregate demand rises Increase in government spending Monetary demand and interest rates increase Output and employment rise Net capital inflows Central bank sells currency and money supply rises Output and employment rise further Assumes high degree of capital mobility For contractionary fiscal policy, reverse all changes Carbaugh, Chap. 17 9 Open economy macro policy Fiscal policy: short run internal effects Under floating exchange rates Aggregate demand rises Increase in government spending Monetary demand and interest rates increase Imports rise and trade account worsens Output and employment rise Net capital inflows Decrease in aggregate demand, output, employment Currency appreciation Assumes high degree of capital mobility For contractionary fiscal policy, reverse all changes Carbaugh, Chap. 17 10 Open economy macro policy Monetary policy: short run internal effects Under floating exchange rates Money supply increases Aggregate demand rises Output and employment rise Interest rate falls Net capital outflows Currency depreciates Exports rise and trade account improves Output and employment rise further Assumes high degree of capital mobility For contractionary monetary policy, reverse all changes Carbaugh, Chap. 17 11 Open economy macro policy Monetary policy: short run internal effects Under fixed exchange rates Money supply increases Aggregate demand rises Interest rate falls Net capital outflows Output and employment rise Central bank purchases currency Money supply decreases Output and employment fall Assumes high degree of capital mobility For contractionary monetary policy, reverse all changes Carbaugh, Chap. 17 12 Open economy macro policy Fiscal & monetary policy: external effects Since floating rates foster BOP equilibrium, focus is on fixed rates In short run, monetary policy has a clear effect on BOP Expansion worsens BOP balance Contraction improves BOP balance Short run effects of fiscal policy are not certain they depend on capital mobility Carbaugh, Chap. 17 13 Open economy macro policy Monetary policy: short run external effects Aggregate demand rises Money supply increases Trade account worsens Interest rates fall Overall BOP worsens Net capital outflows Capital account worsens Assumes high degree of capital mobility For contractionary fiscal policy, reverse all changes Carbaugh, Chap. 17 14 Open economy macro policy Fiscal policy: short run external effects Aggregate demand rises Trade account worsens Increase in government spending Overall BOP may improve Money demand rises Interest rates rise Net capital inflows For contractionary fiscal policy, reverse all changes Carbaugh, Chap. 17 15 Open economy macro policy Policy agreement and policy conflict Monetary policy If a nation has unemployment with a BOP surplus, or inflation with a BOP deficit, an increase/decrease in the money supply will restore both internal and external balances But if a nation has unemployment with a BOP deficit, or inflation with a BOP surplus, a policy aimed at solving one problem will worsen the other Fiscal policy - effects are unclear under those circumstances Carbaugh, Chap. 17 16 Open economy macro policy Policy agreement and conflict (cont’d) In such cases where policy aims do conflict, some combination of fiscal and monetary policy measures will be necessary Some imbalances are even more intractable, such as the case where a nation experiences both inflation and unemployment along with a BOP imbalance, and require a wider range of policy instruments Carbaugh, Chap. 17 17 Open economy macro policy International policy coordination Domestic economic policy moves can spill over to affect other countries Major industrial nations have worked to coordinate economic policy so that external balances are maintained without sacrificing domestic objectives Carbaugh, Chap. 17 18 Open economy macro policy International policy coordination Annual Group of Seven (G-7) economic summits Regular meetings of central bank heads at the Bank for International Settlements Major international policy agreements, such as the Smithsonian Agreement (1971); Bonn Summit (1978); Plaza Accord (1985); Louvre Accord (1987) Carbaugh, Chap. 17 19
