3. 20.1National Output and Value Added Production occurs in stages—most firms produce outputs that are other firms' inputs intermediate products final products Each firm’s contribution to total output is its value added value added = revenues — non-labour costs Copyright © 2014 Pearson Canada Inc. 3 Chapter 20, Slide

4. Summing value added avoids the problem of double counting when measuring total output. Total value added in the economy is called Gross Domestic Product (GDP). 4 Copyright © 2014 Pearson Canada Inc. APPLYING ECONOMIC CONCEPTS 20-1 Value Added Through Stages of Production Chapter 20, Slide

5. 20.2National Income Accounting: The Basics Three methods for measuring national income (output): total value added from domestic production total expenditures on domestic output total income generated by domestic production Because of the circular flow of income, these three measures yield the same total—GDP.

7. GDP from the Expenditure Side Consider adding up the expenditures needed to purchase the final output produced in any given year. There are four broad expenditure categories: consumption investment government purchases net exports Actual consumption expenditure (C a ) includes expenditure on all final goods during the year. 7 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

8. Actual investment expenditure (I a ) is expenditure on the production of goods not for present consumption, including: inventories plant and equipment residential housing Actual government purchases (G a ) is the purchase of currently produced goods and services by government excluding transfer payments. 8 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

9. Actual net exports (NX a ) is the difference between exports and imports: NX a = (X a – Im a ) Exports are purchases of Canadian-produced goods and services by foreigners. We subtract imports because they are not produced in Canada. Since total domestic output must equal total expenditure on domestic output, we have: GDP = C a + I a + G a + NX a 9 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

11. Self-Test Identify the items for the Canadian economy according to the following code: CIGSTXIM or N – not applicable a) A student gets her haircut from self-employed hairdresser b) The hairdresser buys a pair of scissors from the Ace Beauty Supply Company c) Out of each day’s revenue, the hairdresser puts $5 in her piggy bank Chapter 3-11

12. Self-Test continued d) Each time she has enough set aside, the hairdresser buys a share of GM stock e) GM expands its computer facilities in its head office f) American tourists go skiing in the Canadian Rockies g)Two Canadians go to Tokyo and stay at the Hilton Hotel h)Russia buys beef from Alberta ranchers i)The Province of Saskatchewan pays for the building of a new highway Chapter 3-12

13. GDP from the Income Side GDP is also the sum of factor incomes and other claims on the value of output. Factor incomes include: wages rent, interest, and profits Non-factor payments include: indirect taxes (net of subsidies) depreciation of existing physical capital 13 Copyright © 2014 Pearson Canada Inc. net domestic income Chapter 20, Slide

14. GDP from the income side is therefore equal to: GDP = Net domestic income + Indirect taxes (less subsidies) + Depreciation 14 Copyright © 2014 Pearson Canada Inc. EXTENSIONS IN THEORY 20-1 Arbitrary Decisions in National Income Accounting Chapter 20, Slide

18. 20.3National Income Accounting: Some Further Issues GDP and GNP A measure of national output closely related to GDP is Gross National Product (GNP). The difference between GDP and GNP is the difference between income produced and income received. Copyright © 2014 Pearson Canada Inc. 18 Chapter 20, Slide

19. GDP and GNP GDP is superior as a measure of domestic economic activity. GNP is superior as a measure of living standards of residents. A more "refined" measure is disposable personal income: It equals GNP minus: any part not actually paid to households personal income taxes plus transfer payments received by households 19 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

20. Real and Nominal GDP GDP that is valued at constant base-period prices is real national income. The GDP deflator is a comprehensive index of prices because it includes the prices of all goods and services produced in the country. 20 Copyright © 2014 Pearson Canada Inc. GDP Deflator = Nominal GDP Real GDP x 100 Chapter 20, Slide

21. 21 Copyright © 2014 Pearson Canada Inc. Do the CPI and the GDP Deflator Move Together? Broadly, the two price indexes move together, due to underlying inflationary forces. But because one tracks consumer prices and the other tracks the prices of goods produced in Canada, there will be some differences.

23. Omissions from the GDP National income accountants cannot measure economic activity that takes place outside of regular, legal markets: illegal activities leisure the underground economy home production economic "bads" 23 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

24. The current approach is useful because: 1.It would be difficult to correct the major omissions. 2.The level of GDP may be inaccurate but the change in GDP is a good indication of the changes in economic activity. 3.To design policies to control inflation it is necessary to know the flow of money payments made to produce and purchase Canadian output. 24 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide

25. GDP and Living Standards "Well-being" is a broader concept than material living standards: GDP is not a complete measure of economic well-being but income is a very important part of well-being and GDP is a good measure of income. 25 Copyright © 2014 Pearson Canada Inc. Chapter 20, Slide
