Which condition is NOT a required characteristic of a Sweezy oligopoly?
Explanation
The Sweezy oligopoly model is specifically designed for markets with a few firms, barriers to entry, and differentiated products. The key behavioral assumption about asymmetric price reactions would not be as plausible with homogeneous products, where a small price difference could cause a firm to lose all its customers.
