Genuine Progress Indicator GPI v GDP

The Genuine Progress Indicator (GPI) is an attempt to  measure the real increase in economic welfare.

The GPI measures the improvement in economic welfare – costs associated with growth.

The GPI takes a wider measure of economic indicators into consideration. For example, GPI includes

  • value of voluntary work and unpaid work.
  • value of leisure time
  • Distribution of income
  • Impact on environment
  • Environmental standards
  • Cost of crime

See list at bottom for more details.

Advantages of Using GPI

  1. GDP doesn’t take into account negative externalities of growth. Higher GDP may lead to a large rise in pollution, crime and congestion leaving people with lower economic welfare and lower levels of happiness. Therefore, GDP can be misleading as an account of economic welfare.
  2. By focusing on a wider measure of economic indicators, it encourages policy makers to think in broader terms of economic welfare and not just crude GDP statistics.
  3. GDP only measures output – not how it actually effects people’s living standards and how it is used in society.
  4. Encourages long term planning. i.e. sustainable growth rather than short term measures which increase GDP at expense of damaging environment.

Disadvantages of Using GPI

  • Many non-economic variables such as value of leisure time / environment are very subjective and it can be difficult to assign an economic value. GDP is simpler and gives less normative results.
  • Not useful for judging state of business cycle.

Conclusion

Rather than GDP v GPI,  it is useful to use both and see them as complementary indexes. GDP will always have a use for economic accounting. However, it clearly has limitations. Using an additional measure such as GPI helps to give a better understanding of real economic development.
