Firms and resources must be fully mobile, alliowing free 1. Characteristics of competitive markets The competitive market model depends on the following three core assumptions: 1. There must be many buyers and sellers-a few players can't dominate the market. 2. Firms must produce an identical product-buyers must regard all seliers' products as equivalent. 3. Firms and resources must be fully mobile, alliowing 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 lang run without free entry. tdentify whether or not each of the folliowing scenarios describes a competitive market, along with the correct explanatian of why or why not.
