Explanation:

Inflation can be defined as the general rise in the price of goods and services in an economy over a period of time.

There are basically three theories of inflation:

- cost push inflation theory

- sectorial inflation theory

- structural inflation theory

Cost push inflation is caused by the increase in the cost of production which is as a result of a fall in aggregate supply. Cost push inflation may be as a result of increase in the price of raw materials.

Sectorial inflation can be defined as a rise in the prices of goods and services due to different commercial parts of a country.

Structural inflation is as a result of unstable and declining growth rate of export in the economy.
