Major Theories in Macroeconomics

Keynesian theory posits that aggregate demand will not always meet the supply produced.

Monetarism focuses on the macroeconomic effects of the supply of money and the role of central banking on an economic system.

Austrian economic thought is about methodological individualism, or the idea that people will act in meaningful ways which can be analyzed.

Neoclassical and neo-Keynesian ideas can be coupled and referred to as the neoclassical synthesis, combining alternative views in economics.
