Gross domestic product: Are other measures needed?

GDP is the single most important indicator of the overall state of an economy and should be retained.It is a standardized measure across countries, and is relied upon by policymakers to determine whether action is needed to reduce inflation, or to stabilize or grow the economy.However, GDP should be one of a suite of measures.It is unlikely that accounts and measures supplementary to core GDP accounts will give a good sense of a country's future, in part because national income accountants try to avoid making risky, assumption-laden, normative choices, or speculation about what the future might bring.
