In economics, money growth and inflation are closely related. When the money supply in an economy grows rapidly, it can lead to inflation. This is because more money chases the same amount of goods and services, driving up prices. 

Central banks often try to manage money growth to maintain stable inflation rates. According to the classical theory of inflation, money growth causes inflation. The quantity theory of money treats money as neutral. This means that changes in the money supply have no impact on real output. In the long run, real output will depend on resources and technology, not the money supply. 
The main causes of inflation can be grouped into three broad categories: demand-pull, cost-push, and inflation expectations.
