Is it Public or Is it Private?

Marginal Revolution University is an incredible source of economic knowledge. In addition to the course work there are videos and games. Here’s one designed to help distinguish between public goods, private good, common goods and club goods. At the end of the game there is a cheat sheet of how to classify these goods and services.

Pure Private Goods/Services (excludable, rival)
● Haircut
● Pizza
● Website design
● Table service at a restaurant
● Snuggie
● House


Club Goods/Services (excludable, non­rival)
● Netflix
● Amusement park
● Uncongested toll roads (highway)
● The movies
● YMCA membership


Common Goods (non­excludable, rival)
● Busy city street
● Hospital E.R.
● Tuna in the ocean
● The meadow where your sheep graze
● Wildlife
● Forests


Pure Public Goods/Services (non­excludable, non­rival)
● Wikipedia
● National defense
● Uncongested city street
● City fireworks
● Air to breathe
● Google
● Asteroid defense

To understand the economic arrangement I talk about in this blog, these categories have to be rearranged. I ask people to consider that there are two natures to every product: public and private. The nature is dependent upon who, or which group, has access to the goods.

Let me give you an example. A haircut seems like a pretty straightforward private good. The exchange is between two individuals where the customer clearly owns the hair. But what if the haircut was given to disadvantaged kids in an elementary school by a barber who was providing the service as a gesture of community involvement?

The purpose of the activity is to enhance a child’s self esteem and in doing so increase their productivity at school. The barbers work for free so no money is exchanged to make this a private transaction. There are no production reports, nor does this get measured as a part of GDP. This service is done as a public service not a private transaction. Mind you not just anyone can get the free haircut. Only the kids at the elementary school in question. Everyone else must pay. So the public nature has to be attached to that grouping: it is a public good for the elementary school kids.

This is the reason a haircut cannot be classified exclusively as a private service. In due time, I will sort through this whole list of goods and services to convert you to the new classifications of public and private! In due time.
