What is inflation?
Modern economists, with the exception of the Austrian school, use the word inflation to describe a general increase of prices in the economy. This is true, but logically backwards. Suppose there is a boat marina with lots of pylons at the edge of a lake. Suppose, now, that the level of the lake falls. Today’s economists would say there was a general increase in the length of the pylons sticking out of the water.
Inflation is an increase in the money supply – that is, the total amount of money “Chasing” the total amount of goods and services in an economy. The increase in money means each dollar is worth less and consequently, prices rise. To illustrate this, suppose there are 10 people in a room, each with $1. The total money supply is $10. A farmer comes in with 10 grapefruit. In this very simplistic example, a grapefruit might cost $1. Suppose now that everyone is handed an additional dollar such that everyone has $2. A single grapefruit would now cost $2.
Money typically enters the economy through direct loans to large banks and investors (the very rich) and social security and public assistance checks (the very poor). In the case of our grapefruit, if one person was given an additional dollar in advance of the rest, he could still buy grapefruit for $1 each, and buy two of them. The very last to receive the additional dollar would at least have to pay $2, but on the other hand, there may not be a grapefruit left for him.
The grapefruit farmer may see that grapefruit are selling much faster, and double his production. He will take out loans to plant an extra orchard and hire more workers with the expectation of this trend continuing. Eventually though, he will see that he is still only able to sell 10 grapefruit on each trip to the room. He is unable to pay off his loan because he was led to make a bad calculation by inflation – the increase in the money supply.
