Topics of study include economic growth, inflation, unemployment and the business cycle. Macroeconomics also includes the study of government monetary and fiscal policy.
Both microeconomics and macroeconomics are founded upon the economic laws of supply and demand. The branches rely on many of the same fundamental economic ideas, from scarcity to opportunity cost.
In addition to these two major branches, numerous other subfields exist in the economics discipline.
