Stiglitz questions GDP as a measure of progress

by frog

At the request of French President, Nicholas Sarkozy, Nobel Prize winning economist Joseph Stiglitz has produced a report questioning the adequacy of GDP as a measure of progress. From the report: 

Had there been more awareness of the limitations of standard metrics, like GDP, there would have been less euphoria over economic performance in the years prior to the [financial] crisis; metrics which incorporated assessments of sustainability (e.g. increasing indebtedness) would have provided a more cautious view of economic performance. But many countries lack a timely and complete set of wealth accounts— the ‘balance sheets’ of the economy— that could give a comprehensive picture of assets, debts and liabilities of the main actors in the economy.

The report includes key recommendations for fixing the problems with GDP like: ‘look at income and consumption rather than production,’ ‘emphasize the household perspective’ and ‘broaden income measures to non-market activities.’

Another issue the report addresses is GDP’s inability to adequately deal with market failure, especially in relation to environmental and social goods that economists find difficult to measure, so called ‘externalities.’ From the report:

We are also facing a looming environmental crisis, especially associated with global warming. Market prices are distorted by the fact that there is no charge imposed on carbon emissions; and no account is made of the cost of these emissions in standard national income accounts. Clearly, measures of economic performance that reflected these environmental costs might look markedly different from standard measures.

And the report doesn’t overlook the issue of social equity. Income distribution has been identified as a major factor in measuring a society’s overall levels of well-being:

Average income, consumption and wealth are meaningful statistics, but they do not tell the whole story about living standards. For example, a rise in average income could be unequally shared across groups, leaving some households relatively worse-off than others. Thus, average measures of income, consumption and wealth should be accompanied by indicators that reflect their distribution.

President Sarkozy has pledged to incorporate the report’s findings into France’s public accounting systems so that ‘well-being’ will begin to be measured, therefore valued, as at least as important as production.
