Measuring Total Output and Income

6.3 GDP and Economic Well-Being

KEY TAKEAWAYS

  • Real GDP or real GNP is often used as an indicator of the economic well-being of a country.
  • Problems in the measurement of real GDP, in addition to problems encountered in converting from nominal to real GDP, stem from revisions in the data and the difficulty of measuring output in some sectors, particularly the service sector.
  • Conceptual problems in the use of real GDP as a measure of economic well-being include the facts that it does not include nonmarket production and that it does not properly adjust for "bads" produced in the economy.
  • Per capita real GDP or GNP can be used to compare economic performance in different countries.
