Definition: Market Power
Market power refers to the ability of a firm to profitably manipulate price of a good or service by influencing its demand, supply, or both demand and supply. It is the ability of an agent to influence the price and to alter the allocation of resources. Market power is often used to define the monopoly and monopsony concepts.
The model of perfect competition rests on three basic assumptions: (1) price taking, (2) product homogeneity, and (3) free entry and exit. In pure competition sellers are “price takers.” No seller [or buyer] has the ability to influence the market price. The market determines the price.
In most markets, at least one or more of the conditions required for pure competition are violated. This gives sellers or buyers the ability to influence the market price and allocation of resources.
Some of the sources of market power include:
• Monopoly, oligopoly, monopolistic competition: Market power is often considered synonymous with the power that comes with being a monopoly.
• Monopsony, oligopsony
• Institutional structure- taxes, customs etc
