How is the economy built in strategies?

Question

Game development

The question is actually in the title.
Are there any basic rules by which prices, costs, construction time, etc. are determined?
For example, there are two resources, stone and food. Food goes to the construction and support of units, stone - to the construction of buildings. How to calculate prices and production? More precisely, where to start the calculation?
From the abstract "one mill provides food for 10 units, it takes 100 stones to build it, a quarry extracts 25 stones per minute" or something else?
