>Economics is not a science. We cannot execute the scientific method on Economics because we have no way to repeat and or establish controls needed to understand results.
You could say the same thing about mathematics, but it remains the case that it is useful to know some math.
Of course math is not a science either. Ultimately, math is a reasoning tool and in the economic context, it is not a complete tool.
There is policy, and that has a major league effect on what will make good economic sense.
The current policy could change, and that would impact what is worth what and why and the math can tell us what it always has.
Here is one:
For a long time we have ignored anti monopoly laws.
When competition is present, margins are less, people tend to get higher value for the dollar. When it is not present, margins are higher and people get much less value for the dollar.
Right now, big grocery is wanting to do one more merger to basically put Krogers in charge of grocery stores, with its competition being Walmart and maybe Amazon.
So far, each merger has reduced the number of products available to people and higher prices. But someone somewhere is banking more and paying less.
I like competition. I like higher value for the dollar and choice in business. I bring this up because I personally dislike Kroger and it is all about the much lower value per dollar.
How this all goes is political. Policy may be to preserve competition to prevent price gouging and all that comes with a monopoly.
The math may say more dollars are made by having one company, but that same math says it comes at the expense of the people too.
Does not, and I would argue, should not go that way.
