Real versus nominal value (economics)
Gross domestic product (GDP) is a measure of aggregate output. Nominal GDP in a particular period reflects prices which were current at the time, whereas real GDP compensates for inflation. Price indices and the U.S. National Income and Product Accounts are constructed from bundles of commodities and their respective prices. In the case of GDP, a suitable price index is the GDP price index. In the U.S. National Income and Product Accounts, nominal GDP is called "GDP in current dollars" (that is, in prices current for each designated year), and real GDP is called "GDP in [base-year] dollars" (that is, in dollars that can purchase the same quantity of commodities as in the base year).
Urban theory
Arguably, the culprit of this economic entrapment is the high consumption lifestyle synonymous with affluence. The resolve may well be that ‘less is more’ and that true welfare lies not in rise in production and income. As such, Gross Domestic Product (GDP) is increasingly being questioned as inaccurate and inadequate. GDP includes things that do not contribute to sustainable growth and excludes non-monetary benefits that improve the welfare of the people. In response, alternative measures have been proposed such as the Genuine Progress Indicator (GPI) and the Index of Sustainable Welfare - ISEW.
