Stagflation: it occurs when recession and inflation takes place simultaneously in the economy.
Five Macroeconomic Objectives Stable Prices Full employment Sustained Economic Growth External Balances Protection of the Environment
Stable Prices: Price stability has become the primary objective of most governments that wish to secure long-term growth and full employment. Inflation is a process of rising prices. –The inflation rate is measured as a percentage change in the average level of prices or the price level. –Consumer Price Index (CPI) Deflation is negative inflation, the price level is falling.
Inflation In December 1995, the CPI was 153.5 In December 1996, it was 158.6. How would the inflation rate for 1996 be calculated?
Inflation The inflation rate for 1996 was: Inflation = 158.6 – 153.5 153.5 = 3.3% 100
Is Inflation a Problem? Predictability of inflation rates creates problems: High, unpredictable inflation causes resources to be diverted to predicting inflation rates. This is a wasteful use of resources.
Is Inflation a Problem? Hyperinflation –Inflation in excess of 50% per month –Workers are paid daily Money loses value rapidly Workers spend their incomes quickly 1994 Zaire — 76% per month Brazil — 40% per month
Is Inflation a Problem? Policies that reduce the inflation rate increase the unemployment rate.
Sustained Economic Growth Economic growth is the expansion of the economy’s production possibilities. Measured by real gross domestic product (Real GDP) The value of the total production of all the nation’s farms, factories, shops, and offices linked back to the prices of a single year (1992)
The Growth of Potential GDP When an economy’s labor, capital, land, and entrepreneurial ability are fully employed. Real GDP fluctuates around potential GDP Growth slowed during the 1970s Productivity growth slowdown.
External Balance Deficits A government budget deficit exists if the federal government spends more than it collects in taxes.
Deficits An international deficit exists if our imports exceed our exports. Current Account Our exports minus our imports; but it also takes interest payment paid to and received from the rest of the world into account.
Do Deficits Matter? Governments must borrow if it spends more than it earns in tax revenue. If the borrowed funds are used to purchase assets that earn a profit, the investment may be sound.
Government Policy Instruments Fiscal Policy Monetary Policy Direct Policy
Macroeconomic Policy Challenges and Tools Policy Tools (cont.) 1) Fiscal policy Making changes in taxes and government spending. Long-term growth Smooth the business cycle
Macroeconomic Policy Challenges and Tools Policy Tools (cont.) 2) Monetary policy Changing interest rates and the amount of money in the economy Control inflation Smooth business cycle
Coordination of fiscal and monetary policy 3) Direct Policy Many other government economic policies tend to be more ‘objective specific’ compared with the broad macro fiscal and monetary policy options we have considered so far. We refer to these instruments as direct policy, but it is also known as direct control or direct intervention.
Macroeconomic Management Figure 12.2 Business Fluctuations BUSINESS CYCLE –The business cycle occurs because aggregate demand and the short-run aggregate supply fluctuate, but the money wage does not change rapidly enough to keep real GDP at potential GDP. –A below full-employment equilibrium is an equilibrium in which potential GDP exceeds real GDP. –An above full-employment equilibrium is an equilibrium in which real GDP exceeds potential GDP. –A full-employment equilibrium is an equilibrium in which real GDP equals potential GDP.
Fluctuations Around Potential GDP The business cycle is the periodic, but irregular up-and-down movement in production.
Phases of the Business Cycle Recession –Period during which real GDP decreases for two successive quarters. Expansion –Period during which real GDP increases.
Economic Growth in the United States Turning Points Peak –Expansion ends, recession begins. Trough –Recession ends, expansion begins.
Economic Forecasting Exogenous variables are external to the economy in so far as they are determined by world events and policy (i.e oil prices and exchange rates) Endogenous variables are dependent on what goes on within an economy (i.e employment and inflation)
