Inflation occurs: when the overall level of prices rises: It has been shown that increases in the money supply are directly related to the rate of inflation. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy. Government agencies had no money to pay their workers so they started printing money to pay their bills rather than raising taxes. This means that, from one day to the next, prices essentially double. Inflation is when most prices in an entire economy are rising. How can all of these shifts in price be boiled down to a single inflation rate? Before we consider these extreme cases of hyperinflation, let’s first look at inflation itself.
