PART II CONCEPTSAND PROBLEMS IN MACROECONOMICS Introduction to Macroeconomics 5 C H A P T E R O U T L I N E Macroeconomic Concerns Output Growth Unemployment Inflation and Deflation The Components of the Macroeconomy The Circular Flow Diagram The Three Market Arenas The Role of the Government in the Macroeconomy ABrief History of Macroeconomics The U.S. Economy Since 1970 microeconomics Examines the functioning of individual industries and the behavior of individual decision-making units—firms and households. macroeconomics Deals with the economy as a whole. Macroeconomics focuses on the determinants of total national income, deals with aggregates such as aggregate consumption and investment, and looks at the overall level of prices instead of individual prices. aggregate behavior The behavior of all households and firms together. Macroeconomic Concerns Three of the major concerns of macroeconomics are Output growth Unemployment Inflation and deflation Output Growth business cycle The cycle of short-term ups and downs in the economy. aggregate output The total quantity of goods and services produced in an economy in a given period. recession A period during which aggregate output declines. Conventionally, a period in which aggregate output declines for two consecutive quarters. depression A prolonged and deep recession. expansion or boom The period in the business cycle from a trough up to a peak during which output and employment grow. contraction, recession, or slump The period in the business cycle from a peak down to a trough during which output and employment fall. FIGURE 5.1 A Typical Business Cycle In this business cycle, the economy is expanding as it moves through point A from the trough to the peak. The economy is in recession when it moves through point B from a peak down to a trough. FIGURE 5.2 U.S. Aggregate Output (Real GDP), 1900–2009 The periods of the Great Depression and World War I and II show the largest fluctuations in aggregate output. Unemployment unemployment rate The percentage of the labor force that is unemployed. Inflation, Deflation, Disinflation inflation An increase in the overall price level. hyperinflation A period of very rapid increases in the overall price level. deflation A decrease in the overall price level. disinflation A decrease in the rate of inflation The Components of the Macroeconomy Understanding how the macroeconomy works can be challenging because a great deal is going on at one time. Everything seems to affect everything else. To see the big picture, it is helpful to divide the participants in the economy into four broad groups: (1) Households. (2) Firms. (3) The government. (4) The rest of the world. Households and firms make up the private sector, the government is the public sector, and the rest of the world is the foreign sector. The Circular Flow Diagram circular flow A diagram showing the income received and payments made by each sector of the economy. transfer payments Cash payments made by the government to people who do not supply goods, services, or labor in exchange for these payments. They include Social Security benefits, veterans’ benefits, and welfare payments. FIGURE 5.3 The Circular Flow of Payments Households receive income from firms and the government, purchase goods and services from firms, and pay taxes to the government. They also purchase foreign-made goods and services (imports). Firms receive payments from households and the government for goods and services; they pay wages, dividends, interest, and rents to households and taxes to the government. The government receives taxes from firms and households, pays firms and households for goods and services— including wages to government workers—and pays interest and transfers to households. Finally, people in other countries purchase goods and services produced domestically (exports). Note: Although not shown in this diagram, firms and governments also purchase imports. The Three Market Arenas Another way of looking at the ways households, firms, the government, and the rest of the world relate to one another is to consider the markets in which they interact. We divide the markets into three broad arenas: (1) The goods-and-services market. (2) The labor market. (3) The money (financial) market. Goods-and-Services Market Households and the government purchase goods and services from firms in the goods-and-services market. Firms purchase goods and services from each other and also supply to the goods-and-services market. Households, the government, and firms demand from this market. The rest of the world buys from and sells to the goods-and-services market. Labor Market In the labor market, households supply labor and firms and the government demand labor. Labor is also supplied to and demanded from the rest of the world. Money Market Households supply funds to the money market—sometimes called the financial market—in the expectation of earning income in the form of dividends on stocks and interest on bonds. Households also demand (borrow) funds from this market to finance various purchases. Firms borrow to build new facilities in the hope of earning more in the future. The government borrows by issuing bonds. The rest of the world borrows from and lends to the money market. Much of this borrowing and lending is coordinated by financial institutions, which take deposits from one group and lend them to others. *Treasury bonds, notes, and bills Promissory notes issued by the federal government when it borrows money. corporate bonds Promissory notes issued by firms when they borrow money. shares of stock Financial instruments that give to the holder a share in the firm’s ownership and therefore the right to share in the firm’s profits. dividends The portion of a firm’s profits that the firm pays out each period to its shareholders. The Role of the Government in the Macroeconomy fiscal policy Government policies concerning taxes and spending. monetary policy The tools used by the Federal Reserve to control the short- term interest rate. A Brief History of Macroeconomics Great Depression The period of severe economic contraction and high unemployment that began in 1929 and continued throughout the 1930s. Classical theory predicted that the labor market would clear through adjustments in wages and prices, restoring employment and output. sticky prices Prices that do not always adjust rapidly to maintain equality between quantity supplied and quantity demanded. John Maynard Keynes in The General Theory of Employment, Interest and Money. fine-tuning The phrase used by Walter Heller to refer to the government’s role in regulating inflation and unemployment. (1960s) stagflation A situation of both high inflation and high unemployment. (1970s) E C O N O M I C S I N P R AC T I C E Macroeconomics in Literature The underlying The Great Gatsby, set phenomena that in the 1920s economists study are the stuff of novels as well as graphs and equations. If you look at Figure 5.2 for these two periods, you will see the translation of Fitzgerald and Steinbeck into The Grapes of Wrath, macroeconomics. set in the early 1930s The U.S Economy Since 1970 FIGURE 5.4 Aggregate Output (Real GDP), 1970 I–2012 IV Aggregate output in the United States since 1970 has risen overall, but there have been five recessionary periods: 1974 I–1975 I, 1980 II–1982 IV, 1990 III–1991 I, 2001 I–2001 III, and 2008 I2009 II.
