The indicator of the value of money is the general price level. The general price level refers to the average price of goods and services in the economy. It is an important indicator of the purchasing power of money. A high general price level means that money can buy fewer goods and services, while a low general price level means that money can buy more goods and services. Inflation, which is a sustained increase in the general price level, reduces the purchasing power of money over time. Conversely, deflation, which is a sustained decrease in the general price level, increases the purchasing power of money over time.
