Macroeconomics is a branch of economics that deals with the performance,
structure, and behavior of a national economy as a whole.[1] Macroeconomists
seek to understand the determinants of aggregate trends in an economy with
particular focus on national income, unemployment, inflation, investment,
and international trade. In contrast, microeconomics is primarily focused on
the determination of prices and the role of prices in allocating scarce
resources.[1]
While macroeconomics is a broad field of study, there are two areas of
research that are emblematic of the discipline: The attempt to understand
the causes and consequences of short-run fluctuations in national income
(the business cycle), and the attempt to understand the determinants of
long-run economic growth (increases in national income).
Macroeconomic models and their forecasts are used by both governments and
large corporations to assist in the development and evaluation of economic
policy and business strategy.
