National income accounting

  1. 1. 1. Economic Growth2. GNP3. GDP4. National Income Accounting
  2. 2. Prepared by Prof Michael T. Noel
  3. 3.  The income approach is shown on the top half of the circular flow of income and expenditure. Firms make factor payments to households for supplying their services as factors of production.
  4. 4.  National income is the total income earned by citizens and businesses in a country in one year. It consists of employee compensation, rent, interest, and profits.
  5. 5.  Employee compensation consists of payments for labor such as salaries and wages. Rents are payments for use of land and buildings.
  6. 6.  Interest includes payments for loans by households to firms. Profits are payments to the owners of firms.
  7. 7.  Income and expenditures must be equal because of the rules of double-entry bookkeeping. Profit is the balancing item.
  8. 8.  GDP is calculated either by adding up all values of final output or by adding up the values of all earnings or income.
  9. 9.  To go from GDP to national income: ◦ Add net foreign factor income.  National income is all income earned by citizens of a nation and is equal to GNP.  To move from "domestic" to "national" we add net foreign factor income. ◦ Subtract depreciation from GDP. ◦ Subtract indirect business taxes from GDP.
  10. 10. Net foreign Depreciation factor income Net exports Indirect business taxesGovernment Rentsexpenditures Interest Investment Profits GDP GNP NationalConsumption Income Employee compensation (1) (2) (3)Expenditures = Output = Income
  11. 11.  Personal income (PI ) is national income plus net transfer payments from government minus amounts attributed but not received. PI = NI + Transfer payments from government + Net non-business interest income – Corporate retained earnings – Social security taxes
  12. 12.  Disposable personal income is personal income minus personal income taxes and payroll taxes. Disposable personal income is what people have readily available to spend. DPI = PI - Personal taxes
  13. 13.  GDP figures are used to make comparisons among countries and to measure economic welfare over time.
  14. 14.  GDP gives a measure of economic size and power. Per capita GDP is another measure often used to compare nations GDP. Because of differences in non-market activities, per capita GDP can be a poor measure of the living standards in various nations.
  15. 15.  Purchasing power parity is used to get around the problems of per capita GDP. Purchase power parity adjusts for different relative prices among nations before making comparisons.
  16. 16.  Just because GDP rose does not mean welfare rose – it could be only prices rose. Comparing output over time is best done with real output which is nominal output adjusted for inflation.
  17. 17.  Nominal GDP is GDP calculated at existing prices. Real GDP is nominal GDP adjusted for inflation.
  18. 18.  Real GDP is important to society because it measures what is really produced. Real GDP is arrived at by dividing nominal GDP by the GDP deflator.
  19. 19.  Limitations of national income accounting include the following: ◦ Measurement problems exist. ◦ GDP measures economic activity, not welfare. ◦ Subcategories are often interdependent.
  20. 20.  GDP does not measure happiness, nor does it measure economic welfare. Welfare is a complicated idea, very difficult to measure.
  21. 21.  GDP figures leave out the following: ◦ Illegal drug sales. ◦ Under-the-counter sales of goods to avoid income and sales taxes. ◦ Work performed and paid for in cash. ◦ Unreported sales. ◦ Prostitution, loan sharking, extortion, and other illegal activities.
  22. 22.  A second type of measurement error occurs in adjusting GDP for inflation. If the price and the quality of a product go up together, has the price really gone up? Is it possible to measure the value of quality increases?
  23. 23.  The subcategories of GDP can be misinterpreted. ◦ For example, the line between investment and consumption is often fuzzy.
  24. 24.  The genuine progress indicator (GPI) is an alternative measure to GDP. The GPI tries to measure pollution, education, health concerns, as well as GDP.
