Question

the level of competition least benifical to business owners is

Answer 1

I would propose several operators at an equal level of supply and demand as the ideal market condition for business owners,with the caveat that this is IF you want all business owners to thrive somewhat equitably and all be given a fair chance in the market..

In real life however I would say the ideal environment for my own business to operate would be with an advantage in supply so I ould control prices and thus the market,in turn becoming the largest buisness and cornering the market forcing the competitors out of business..so there's definitely several ways to view this.

Answer 2

Answer 3

a even number of competition is best
