A market refers to a system or an environment where parties engage in the exchange of goods, services, or information. It can encompass various forms of interactions, including selling and buying, both in physical locations, such as a marketplace or store, and through virtual settings, such as online platforms. Markets are characterized by the dynamics of supply and demand, where the prices of goods and services are determined by the willingness of buyers to purchase and sellers to provide them. They can be classified into different types, including perfect competition, monopolistic competition, oligopoly, and monopoly, based on the number of participants and the nature of competition. Additionally, markets can be segmented based on various criteria such as geography, demographics, or product type, leading to subcategories like labor markets, financial markets, or commodity markets. Overall, a market plays a crucial role in the economy by facilitating trade and influencing resource allocation.
