Study of the entire economy in terms of the total amount of goods and services produced, total income earned, level of employment of productive resources, and general behaviour of prices.
Until the 1930s, most economic analysis focused on specific firms and industries. The aftermath of the Great Depression and the development of national income and production statistics brought new interest to the field of macroeconomics. The goals of macroeconomic policy include economic growth , price stability, and full employment. See also microeconomics ; national income accounting .
