Macroeconomics is the study of the entire economy in terms of the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the general behavior of prices. Macroeconomics can be used to analyse how best to influence policy goals such as economic growth, price stability, full employment and the attainment of a sustainable balance of payments.

Until the 1930s most economic analysis concentrated on individual firms and industries. With the Great Depression of the 1930s, however, and the development of the concept of national income and product statistics, the field of macroeconomics began to expand. Particularly influential were the ideas of John Maynard Keynes, who used the concept of aggregate demand to explain fluctuations in output and unemployment. Keynesian economics is based on his ideas.

One of the great challenges of recent economics has been a struggle to reconcile macroeconomic and microeconomic models. Theorists such as Robert Lucas Jr suggested (in the 1970s) that at least some traditional Keynesian macroeconomic models were questionable as they were not derived from assumptions about individual behavior.

Today the main schools of macroeconomic thought are as follows:
