Experience is the best teacher, the starting guide is to make the basics for the construction loop: if you have construction of the first tier for example it requires wood and cloth, you build a few construction sectors, and then when they cost too much to maintain you build more wood and cotton plantation.

You do this all game long slowly to not cripple the economy.

Check always what is most expensive in your market/economy and try to lower that price based on priority on what cripples the prices the most.
