How is inflation caused?

we get two types of inflation

demand-pull inflation, this inflation is happened from demand increase, the demand increase, the price gonna increase too. the cpi ( inflation ) index also increase.

another type is cost-push inflation, this type is from cost increase. the wage rate and the price of raw materials increase, the cost of goods and service going up, and the price of goods and services also going up. that's the reason why inflation happened.

hope this can help you
