Two bits on inflation.

Recently a friend explained the meaning of the phrase “two bits” to me.
It means “25 cents”. He recalls hearing a song on the radio when he was young that went “two bits, four bits, six bits, a dollar”. While I was unable to find this song (the closest I came was a Florida state sports cheer), I did stumble on some more of the history behind the expression.

Back when the Age of Discovery was still underway, many countries were basing their currency on the Spanish silver dollar. Spanish silver dollars were often cut into eight pieces (like the slices of a pie). These smaller pieces were used as coins worth fractions of a dollar. Thus the Spanish silver dollar coin was also sometimes called “a piece of eight”, as it could be cut into eight “reales” or “bits”.

Many fledgling governments based their currency on the Spanish silver dollar. In 1792 the US government created a standardized currency for itself. The newly-founded U.S. Mint fixed the value of the American dollar to that of the Spanish silver dollar. When the first American quarter-dollars were minted, each was worth two 1/8 bits of a Spanish silver dollar.

Of course, inflation happened, as it usually does, and the Spanish pieces of eight (or “pesos”) were made with less silver than older ones, and their size kept dropping. The same could be said of Mexican Pesos, which started out based on the Spanish silver dollar as well. Eventually America went off the gold standard as well.

This brought the tune of “shave and a haircut (two bits)” to mind… Those words accompanying the tune date back to the 1930s… and provide us with an inkling of prices then.

It’s hard for the younger of us to imagine that a quarter used to be worth that much.
Nowadays I understand that a haircut tends to cost about $25.00 – one hundred times as much, in less than a hundred years.

It’ll be interesting to see how much one costs five years from now.

A Science for Everyone

Inflation

Inflation is one of the very basic, very important economic concepts. It is deceptively simple. Increase the supply of money, and it’s like inflating a balloon. The amount of air in the balloon increases, the amount of money in the system increases. This is essentially what happens whenever the government prints more money.

When the amount increases, the value of each individual unit goes down. This becomes more difficult to understand, because a dollar is still a dollar. However, a dollar doesn’t purchase as much.

Think back. Remember. How much was gasoline ten years ago? Twenty? Thirty? But it’s not always the price that increases. Sometimes, the amount goes down. Candy-bars, anyone? They’ve shrunk considerably since I was a child admiring them in the checkout isle. Of course, some things increase in efficiency and decrease in price, even while others do the opposite. Why? Developing technology can really reduce the costs of making something, sometimes enough that the price declines, even as the value of money goes down.

The federal reserve aims for an inflation rate of 2%. But that’s a number with very little meaning to most people. We care more about how much the grocery bill will increase by. For that, we look at the consumer price index. Calculating how much the value of money has changed is as simple as having two reference points. Pick an item. What does it cost today? What did it cost back then? Do a little subtraction, and then a little division.

Of course, you could also use the CPI inflation calculator provided by the government. In that case, it told me that a 100$ in 1920 had the same purchasing power as $1,342.65 in 2020.

Why do we care about inflation? Sure, groceries cost more, gas costs more, electricity costs more, but we’re earning more too, right? Eventually, probably. What’s really concerning is when inflation is high, when you see the kind of chance the US dollar had from 1920 to 2020 over the course of a year. Wages just can’t keep up.

Literally printing more money, while the obvious (and easiest) means of causing inflation, isn’t the only way to go about it, but the alternatives are a bit complex for this summary.
