1.There must be many buyers and sellersa few players can't dominate the market.2.Firms must produce an identical productbuyers 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.
