Perfectly Competitive Markets
Perfect competition is a market structure where many firms offer a homogeneous product.
Because there is freedom of entry and exit and perfect information, firms will make normal
profits and prices will be kept low by competitive pressures. In other words it can be said that a
market is said to be perfect when all the potential buyers and sellers are promptly aware of the
prices at which transaction take place. Under such conditions the price of the commodity will
tend to be equal everywhere.
In order for a market to have perfect competition, there must be:
• Identical products sold by companies
• An environment in which prices are determined by supply and demand, meaning
companies cannot control the market prices of their products
• Equal market share between companies
• Complete information about prices and products available to all buyers
• An industry with low or no barriers to entry or exit
Perfect competition describes a market structure whose assumptions are strong and therefore
unlikely to exist in most real-world markets. We can however take some useful insights from
studying a world of perfect competition and then comparing and contrasting with real-world
imperfectly competitive markets and and industries. A perfect market is used as a standard by
which the effectiveness and efficiency of real-world markets can be measured. While no market
has clearly defined perfect competition, all real-world markets are classified as imperfect.
Imperfect competition occurs in a market when one of the conditions in a perfectly competitive
market are left unmet. This type of market is very common. In fact, every industry has some type
of imperfect competition. This includes a marketplace with different products and services,
prices that are not set by supply and demand, competition for market share, buyers who may not
have complete information about products and prices, and high barriers to entry and exit.
A perfect market is a theoretical concept in microeconomics that is used as a standard to measure
the effectiveness and efficiency of real-world markets. In a perfect competition environment, the
following criteria must be met:
• Companies sell identical products
• They cannot influence how much they charge for these products
• Market share has no bearing on prices
• Everyone is privy to the same information
• Firms can enter or exit the market without incurring any costs
Imperfect competition can be found in the following types of market structures:
• Monopoly- This is a structure in which there is only one (dominant) seller.
• Oligopoly- This structure has many buyers but few sellers.
