  • WPI is released by the Economic Advisor in the Ministry of Commerce and Industry.

  • Inflation is classified into three types: Demand-Pull inflation, Cost-Push inflation, and Built-In inflation.

Types of Inflation:

  • Demand-pull inflation is the upward pressure on prices that follows a shortage in supply. 
  • Cost-push inflation: It is a result of the increase in the prices of production process inputs. 
  • Built-in inflation: It is the third cause that links to adaptive expectations. As the price of goods and services rises, labor expects and demands more costs/wages to maintain their cost of living.
