Perfect competition What is perfect competition? How does it work? And why does it matter? Perfect competition is that theoretical structure of the market in economics where a high number of buyers and sellers engage in the market and no single agent has the power to change the market price. It\'s often considered the ideal or standard model for understanding how markets efficiently work. Perfect competition doesn\'t exist in the real world very often, but it still gives an important framework for thinking about market dynamics, efficiency, and the allocation of resources. In this article, we will discuss the essential characteristics of perfect competition, conditions, theoretical concept versus its applicability in real life, advantages and disadvantages, comparison with monopoly, and practical illustrations on how it can be manifested or approximated in practice. What is Perfect Competition? Perfect competition is an economic term in describing a market structure. Perfect competition entails the existence of several buyers and sellers, homogenous products, perfect information, and easiness in entry and exit. In a perfectly competitive economy, no single firm and no single consumer can be able to influence the price, and the market allocates resources efficiently. This ideal market is based on a number of assumptions that simplify economic analysis, so economists can study the forces of supply and demand without complicating factors found in more complex market structures. Perfect competition results in the most efficient outcome both in terms of production and consumption in maximizing total welfare of an economy. How Does Perfect Competition Work? In a perfectly competitive market, forces of demand and supply determine the equilibrium price and quantity. Let\'s take a look at the mechanics: Supply and Demand Dynamics Demand: Consumers would want a good at different prices; as the price continues to decline, their purchasing power increases. Supply: The suppliers would supply a good based on the price they can get. If the prices are increasing, the incentive would be for them to provide more. Under perfect competition, firms are price takers. Market supply and demand intersect to determine the price. Because all firms sell homogeneous goods, no firm can charge above the market equilibrium to lose no customers to competitors. Firms\' Behavior Profit Maximization: At the level where MC = MR, firms maximize profits. Since, under perfect competition, P = MR the firms determine output with an objective of maximum profit operating in this equilibrium condition wherein P and MR are the same Short-run and Long-run Equilibrium : In the short-run supernormal profits(super normal profits- returns more than normal return from investment )or loss could be generated. However, in the long-run, due to the ease with which entry and exit occur, it is impossible for firms to retain long-run profits. Some short-run profit attracts new firms and increases supply, push
