Changes in aggregate supply or demand, which can occur for numerous reasons, lead to new levels of GDP and prices An increase in consumption expendature (C), business investment (I), or government spending (G), for example, would increase aggregate demand When GDP or price levels are not at their desired levels, macroeconomic monetary or fiscal policy may be prescribed

All rights reserved. 11-9 Two Categories of Macroeconomic Policies Fiscal policy: government taxation and expenditures; usually formulated by the legislative and executive branches Monetary policy: money supply and interest rates; usually formulated by the central bank and the finance ministry Let’s analyze fiscal and monetary policies in detail…

Copyright © 2005 Pearson Addison-Wesley. All rights reserved. 11-10 Fiscal Policy Expansionary fiscal policy: increase in government spending and/or cuts in taxes; result in an increase in output – Multiplier effect: increase in demand ultimately results in an even larger increase in production and income as effects of the demand hike run through the economy Contractionary fiscal policy: cuts in government spending and/or increases in taxes – Have a negative multiplier effect

All rights reserved. 11-11 Monetary Policy Works through a combination of change to the supply of money and change to interest rates Open market operations: central bank´s buying and selling of bonds in the open market – Selling bonds leads the nation’s financial institutions to give up some of their cash, with cash reserves shrinking throughout the economy
12
Copyright © 2005 Pearson Addison-Wesley. All rights reserved. 11-12 Monetary Policy (cont.) Central bank’s increasing the supply of money in he economy reduces the interest rate – Expansionary monetary policy: an increase in the money supply and decrease in interest rates – Contractionary monetary policy: a decrease in the money supply and a rise in interest rates

Copyright © 2005 Pearson Addison-Wesley. All rights reserved. 11-19 Marco Policies for Current Account Imbalances Expenditure switching polices and expenditure reducing policies: a combination of fiscal, monetary, and exchange rate policies for addressing current account imbalances – Expenditure switching policies include exchange rate depreciation and trade barriers – Expenditure reducing policies are contractionary monetary or fiscal polices
20
Copyright © 2005 Pearson Addison-Wesley. All rights reserved. 11-20 Marco Policies for Current Account Imbalances (cont.) The two policies must be applied simultaneously: expenditure shifts without expenditure reductions are inflationary, while expenditure reductions without shifts toward domestic producers is recessionary
21
Copyright © 2005 Pearson Addison-Wesley. All rights reserved. 11-21 The Adjustment Process Adjustment process: describes changes in the trade deficit that are caused by a change in the exchange rate – For example, depreciation raises the real price of foreign goods, making domestic substitutes more attractive – Depreciation has, however, a time lag – Moreover, the first impact of depreciation may be a J-curve: a deterioration of the current account
