Characteristics of competitive markets The model of competitive markets relies on these three core assumptions: 1. There must be many buyers and sellersâa few players can't dominate the market.

2. Firms must produce an identical productâbuyers must regard all sellers' products as equivalent

. 3. Firms and resources must be fully mobile, allowing free entry into and exit from the industry. The first two conditions imply that all consumers and firms are price takers.

While the third is not necessary for price-taking behavior, assume for this problem that a market cannot maintain competition in the long run without free entry.
