Perfectly competitive markets are characterized by large numbers of buyers and sellers who cannot influence market prices and who buy and sell identical products.
Although in reality, most markets do not perfectly adhere to the assumptions of the perfectly competitive markets, some markets are very close to perfect competition.
For example, the market for rice has millions of consumers who buy rice, as well as thousands of farmers producing and selling rice. These consumers and producers take the market price as given and make their production and consumption decisions based on this prevailing price.
