Supply Side Economics?

 Break on Through

You know the day destroys the night
Night divides the day
Tried to run
Tried to hide
Break on through to the other side

So what is supply side economics?

Supply side economics assumes that increasing the supply of goods can stimulate the economy.  This is the opposite from a demand side economics, also known as Keynesian, stimulus which seeks to  increase  the demand for goods, by increasing the purchasing ability of buyers. 

To properly execute this supply side policy, it is necessary to properly define the production equation of suppliers.  The production  equation is traditionally thought to be a function of only capital and labor. However capital is not only investment but also supplying the raw materials, goods, needed to produce a product.  Economists classify goods not simply as free and priced.  Economists use an additional attribute besides price, exclusivity.  A good is exclusive if it can not be used by more than one person at a time. For example my eating a piece of bread means that you can not also eat that piece of bread, i.e. it is exclusive. By contrast, my watching a movie does not prevent you from also watching that same movie, i.e. it is Non-exclusive.

This leads to not just two classes of goods, Private and Public, but four classes of goods. These include Priced and Exclusive, which are Private goods, and  Non-priced and Non‑exclusive, which are Public goods. But it also includes Natural Monopolies: Priced and Non-exclusive; and Common Resources: Non-priced and Exclusive. Suppliers acknowledge natural monopolies, e.g. a cable TV company.  My watching cable TV does not prevent my neighbor from also watching cable TV, but both of us separately pay the cable TV provider.  ( if you have cut the cord like I have, substitute Disney+ or any streaming provider in this example.) The initial cost of Natural Monopolies  is often high, thus society offers protections, e.g. an exclusive franchise to offer cable, to industries to encourage then to make that initial investment.  Industry seems less inclined to acknowledge  Common Resources.  Fishing stocks are a common resource.  It is exclusive. If I eat a fish, then you can not eat that same fish. That fish might be free and the stock may seem vast but it is really has a limit.  Just as it is in society’s interest to encourage industries to invest in natural monopolies, society may spend to increase, or regulate in order to protect, those common resources.  Fishing stocks are regulated to prevent overfishing.  An educated workforce may be necessary for suppliers, but education is a common resource and society invests in education to provide this work force.  Just because a good does not have a price does not mean that society can’t regulate, or spend, to ensure that this common resource will continue to exist, and might even increase.

“Supply side” economics, as it is currently practiced, stimulates the economy by encouraging INVESTMENT.  If the production equation did not require any common resources, including public education and public highways, as raw materials, then neglecting measures to stimulate labor, encouraging investment should increase supply in the long run.  However if the production equation relies on common resources, eliminating regulations on, and decreasing expenditures for, common resources will in the long run DECREASE supply.  Thus the so-called “Supply side” policies have seemed to serve only to reward investment. It provides no reward for labor and reduced common resources.  Truly supply-side economics would also ensure that common goods, as regulated and/or provided by society, increase. Supply side stimulus might be an alternative to demand side stimulus, but what had been practiced has NOT been supply side economics, even if it is called supply side economics.  It is more properly “Investment”  economics at the  expense of Labor and Common Resources.
