The document discusses the role of businesses in the economy. It states that businesses allow for specialization of production and economies of scale, which lower costs. They also coordinate trade and commerce through markets. Markets allow buyers and sellers to discover information and exchange goods and services voluntarily. This benefits consumers by providing access to desired goods and services and transmitting price information. It increases standards of living by enabling specialization and trade beyond self-sufficiency. Businesses thus play a key role in production, trade, and economic growth.
