Market Structure Explained: Types of Market Structure in Economics

Market structure, in economics, is the organisational and competitive nature of a market. It defines how firms will act, how prices will be set, and how resources will be allocated efficiently. The essential components of market structure are:

• The number of buyers and sellers in the market.
• The type of products, whether homogeneous or differentiated.
• The degree of barriers to entry and exit.
• The extent of pricing power that firms enjoy.
• The level of competition in the market.

These factors help in understanding why firms follow different strategies in different industries and why the skills required by firms differ from one firm to another.
