8 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Chapter Objectives u State why national income accounting is important. u Define GDP, GNP, and NI. u Calculate GDP in a simple example, avoiding double counting.

9 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Chapter Objectives u Explain why GDP = C + 1 + G + (X - M).

10 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Chapter Objectives u Explain why GDP = C + 1 + G + (X - M). u Distinguish between real and nominal values.

11 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Chapter Objectives u Explain why GDP = C + 1 + G + (X - M). u Distinguish between real and nominal values. u State some limitations of national income accounting.

12 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u In the 1930s it was impossible to talk intelligently about macroeconomics since the discussion lacked rigorous terminology.

13 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u In the mid-1930s, Keynesians Simon Kuznets and Richard Stone began to develop this terminology.

14 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u They developed national income accounting—a set of rules and definitions for measuring economic activity in the aggregate economy—that is, in the economy as a whole.

15 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services

16 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services l Gross Domestic Product (GDP) is the total value of all final goods and services produced in an economy in a one-year period.

17 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services l Gross Domestic Product (GDP) is the total value of all final goods and services produced in an economy in a one-year period. u It is the single most-used economic measure.

18 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services l Gross National Product (GNP) is the aggregate final output of citizens and businesses of an economy in one year.

19 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services l GDP measures the economic activity that occurs within a country.

20 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Measuring Total Economic Output of Goods and Services l GDP measures the economic activity that occurs within a country. l GNP measures the economic activity of the citizens and businesses of a country.

21 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Moving from GDP to GNP

22 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Moving from GDP to GNP l To move from GDP to GNP, net foreign factor income is added to GDP.

23 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Moving from GDP to GNP l Net foreign factor income is the income from foreign domestic factor sources minus foreign factor incomes earned domestically.

24 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill National Income Accounting u Moving from GDP to GNP l One must add the foreign income of one's citizens and subtract the income of residents who are not citizens.

25 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u All goods and services produced by an economy must be weighted, that is, each good and service must be multiplied by its price.

26 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u Once quantities of a particular good or service are multiplied by its price, we arrive at a value measure of the good or service.

27 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u Finally, all the value measures are added to arrive at GDP.

28 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u GDP is a flow concept.

29 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u The store of wealth is a stock concept.

30 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP u The stock equivalent to National Income Accounts is the Wealth Accounts—a balance sheet of an economy’s stocks of assets and liabilities.

31 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill GDP Measures Final Output u When one firm sells products to another firm for use in production of yet another good, the first firm’s products are not considered final output but intermediate products.

32 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill GDP Measures Final Output u When one firm sells products to another firm for use in production of yet another good, the first firm’s products are not considered final output but intermediate products. l Intermediate products are used as input in the production of some other product.

33 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill GDP Measures Final Output u Not accounting for intermediate products would result in double and triple counting.

34 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill GDP Measures Final Output u Not accounting for intermediate products would result in double and triple counting. l If we did not eliminate intermediate goods, a change in organization—say, a merger— would look like a change in output

35 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Two Ways of Eliminating Intermediate Goods u The first is to calculate only final output.

36 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Two Ways of Eliminating Intermediate Goods u A second way is to follow the value added approach. l Value added is the increase in value that a firm contributes to a product or service.

37 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Two Ways of Eliminating Intermediate Goods u A second way is to follow the value added approach. l Value added is the increase in value that a firm contributes to a product or service. l It is calculated by subtracting intermediate goods from the value of its sales.

43 © The McGraw-Hill Companies, Inc., 1998 Irwin/McGraw-Hill Calculating GDP: Some Examples u Selling your car to a used car dealer who sells your car to someone else for a higher price, does add to GDP. l The value added is the dealer's services.
