Markets are places or systems where buyers and sellers come together to exchange goods and services. They can be physical locations, like a farmers' market, or virtual platforms, such as online marketplaces. Prices in markets are determined by supply and demand, meaning that when more people want a product, its price tends to rise, and when there is less interest, the price usually falls. There are different types of markets, including stock markets, where shares of companies are bought and sold, and labor markets, where employers seek workers. Each market operates under its own rules and dynamics, influencing how transactions occur and how prices are set.
