A completely competitive market exists when each member is a price taker. In a competitive market, there are many buyers and sellers, none of whom can influence the market price on their own. In other words, each member of the market is a price taker, meaning they must accept the market price for the goods or services they are buying or selling. Because no single buyer or seller has enough market power to set the price, the market price is determined solely by the interaction of supply and demand. In a completely competitive market, the goods or services being bought and sold are identical, so there is perfect substitutability between suppliers, and buyers will choose the lowest price available. Overall, a completely competitive market is considered to be efficient, because it results in a fair and optimal allocation of resources, as each member is incentivized to produce and consume at the market-determined price.
