The article explores how to control inflation when money can move freely between countries. It looks at different ways to stabilize prices, like controlling how much money is created or setting fixed exchange rates. The study finds that reducing inflation takes time and requires cutting demand. Lowering inflation can also lead to higher real demand and interest rates. This can affect the balance of payments and exchange rates. While a temporary increase in the value of money can help lower inflation, it doesn't last forever and can cause problems later on.
