Nobel winner Joseph Stiglitz explains why GDP is NOT a good measure of society’s well-being and offers ideas on better measures. It’s a good critique of GDP.
National income statistics such as GDP and gross national product were originally intended as a measure of market economic activity, including the public sector. But they have increasingly been thought of as measures of societal well-being, which they are not. Of course, good statisticians have warned against this error. Much economic activity occurs within the home – and this can contribute to individual well-being as much as, or more than, market production.
What we measure affects what we do. If we have the wrong metrics, we will strive for the wrong things. In the quest to increase GDP, we may end up with a society in which most citizens have become worse off. We care, moreover, not just for how well off we are today but how well off we will be in the future. If we are borrowing unsustainably from this future, we should want to know.
