2.3 Market Structures

Market structures refer to the organisational and competitive characteristics of a market, which play a crucial role in determining how prices are set and how firms behave. The three primary market structures, perfect competition, monopoly, and oligopoly, each exhibit distinct features that influence market dynamics, consumer choices, and overall economic efficiency.

Perfect competition represents an ideal market structure where numerous small firms compete against one another, producing homogeneous products, meaning the products are identical and indistinguishable from one another. In this scenario, no single firm has the power to influence market prices, instead, prices are determined by the forces of supply and demand.

Perfect competition is characterised by several key features that ensure a highly competitive market environment. There are many buyers and sellers, meaning no single entity has the power to influence prices. All firms offer homogeneous products, so consumers base their purchasing decisions solely on price rather than product differentiation.

Additionally, free entry and exit allow firms to enter or leave the market without significant barriers, ensuring that long-term profits are minimised and firms operate efficiently. Lastly, perfect information ensures that all market participants have access to relevant data, enabling consumers to make well-informed choices and fostering transparency in the market.
