I noticed on a recent question that we have at least three price-related tags price, pricing and price-theory. None have any usage information attached right now. Is more than one price tag necessary and if so when?
As a first step to answering the question, I am creating this community wiki to figure out what the usage descriptions would be if we decided to keep all three tags. Then we can take stock of whether they are independently useful.
Everyone should feel free to refine or change the definitions.
Price (taken from Wikipedia)
A price is the quantity of payment or compensation given by one party to another in return for one unit of goods or services.
The problem of determining the approriate price for one or more goods and services.
Price theory (from Glen Weyl, who identifies himself as probably the only price theorist under the age of 40)
Analysis that reduces rich and often incompletely specified models into ‘prices’ sufficient to characterize approximate solutions to simple (e.g. one-dimensional policy) allocative problems.
