3. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 3 of 36 MEASURING NATIONAL OUTPUT AND NATIONAL INCOME national income and product accounts Data collected and published by the government describing the various components of national income and output in the economy.

4. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 4 of 36 GROSS DOMESTIC PRODUCT gross domestic product (GDP) The total market value of all final goods and services produced within a given period by factors of production located within a country. GDP is the total market value of a country’s output. It is the market value of all final goods and services produced within a given period of time by factors of production located within a country.

5. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 5 of 36 GROSS DOMESTIC PRODUCT final goods and services Goods and services produced for final use. FINAL GOODS AND SERVICES intermediate goods Goods that are produced by one firm for use in further processing by another firm. value added The difference between the value of goods as they leave a stage of production and the cost of the goods as they entered that stage.

6. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 6 of 36 To arrive at GDP, the Bureau of Economic Analysis (BEA) counts: a.The value of total sales, including sales to suppliers and sales to consumers. b.The value of final sales. c.The value of intermediate goods and final goods. d.Value added plus the value of sales at the retail level. e. Any of the above.

7. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 7 of 36 To arrive at GDP, the Bureau of Economic Analysis (BEA) counts: a.The value of total sales, including sales to suppliers and sales to consumers. b.The value of final sales. c.The value of intermediate goods and final goods. d.Value added plus the value of sales at the retail level. e. Any of the above.

8. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 8 of 36 GROSS DOMESTIC PRODUCT Tires taken from that pile and mounted on the wheels of the new car before it is sold are considered intermediate goods to the auto producer. Tires from that pile to replace tires on your old car are considered final goods. If, in calculating GDP, we included the value of the tires (an intermediate good) on new cars and the value of new cars (including the tires), we would be double counting.

9. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 9 of 36 GROSS DOMESTIC PRODUCT In calculating GDP, we can either sum up the value added at each stage of production or we can take the value of final sales. We do not use the value of total sales in an economy to measure how much output has been produced.

10. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 10 of 36 GROSS DOMESTIC PRODUCT GDP ignores all transactions in which money or goods change hands but in which no new goods and services are produced. EXCLUSION OF USED GOODS AND PAPER TRANSACTIONS GDP is concerned only with new, or current, production.

11. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 11 of 36 GROSS DOMESTIC PRODUCT GDP is the value of output produced by factors of production located within a country. EXCLUSION OF OUTPUT PRODUCED ABROAD BY DOMESTICALLY OWNED FACTORS OF PRODUCTION gross national product (GNP) The total market value of all final goods and services produced within a given period by factors of production owned by a country’s citizens, regardless of where the output is produced.

CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 14 of 36 CALCULATING GDP expenditure approach A method of computing GDP that measures the amount spent on all final goods during a given period. income approach A method of computing GDP that measures the income—wages, rents, interest, and profits—received by all factors of production in producing final goods.

15. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 15 of 36 CALCULATING GDP THE EXPENDITURE APPROACH There are four main categories of expenditure: Expenditure Categories: ■Personal consumption expenditures (C): household spending on consumer goods ■Gross private domestic investment (I): spending by firms and households on new capital, i.e., plant, equipment, inventory, and new residential structures ■Government consumption and gross investment (G) ■Net exports (EX - IM): net spending by the rest of the world, or exports (EX) minus imports (IM) GDP = C + I + G + (EX - IM)

46. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 46 of 36 The difference between nominal GDP and real GDP comes from: a.Changes in the level of income. b.Changes in purchasing power of the dollar caused by changes in the exchanger rate. c.Changes in prices. d.Differences in the value of GDP depending on whether the income approach or the expenditure approach is chosen to compute GDP.

48. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 48 of 36 NOMINAL VERSUS REAL GDP CALCULATING THE GDP DEFLATOR The GDP deflator is one measure of the overall price level. The GDP deflator is computed by the Bureau of Economic Analysis (BEA). Overall price increases can be sensitive to the choice of the base year. For this reason, using fixed-price weights to compute real GDP has some problems.

49. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 49 of 36 NOMINAL VERSUS REAL GDP THE PROBLEMS OF FIXED WEIGHTS The use of fixed-price weights to estimate real GDP leads to problems because it ignores: Structural changes in the economy. Supply shifts, which cause large decreases in price and large increases in quantity supplied. The substitution effect of price increases.

50. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 50 of 36 LIMITATIONS OF THE GDP CONCEPT GDP AND SOCIAL WELFARE Society is better off when crime decreases; however, a decrease in crime is not reflected in GDP. An increase in leisure is an increase in social welfare, but not counted in GDP. Nonmarket and household activities are not counted in GDP even though they amount to real production.

51. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 51 of 36 LIMITATIONS OF THE GDP CONCEPT THE UNDERGROUND ECONOMY underground economy The part of the economy in which transactions take place and in which income is generated that is unreported and therefore not counted in GDP. Whenever sellers looking for a profit come into contact with buyers willing to pay, markets will arise, often “underground.”

52. CHAPTER 6: Measuring National Output and National Income © 2007 Prentice Hall Business Publishing Principles of Economics 8e by Case and Fair 52 of 36 Legalizing all forms of illegal activities would: a.Reduce both the underground economy and GDP. b.Increase both the underground economy and GDP. c.Increase the underground economy but reduce the value of GDP. d.Reduce the underground economy and increase the value of GDP.
