An economy encompasses all activity related to production, consumption, and trade of goods and services in an area. An economy applies to everyone from individuals to entities such as corporations and governments. The economy of a particular region or country is governed by its culture, laws, history, and geography, among other factors, and it evolves due to necessity. For this reason, no two economies are identical. Market-based economies allow goods to flow freely through the market, according to supply and demand. The United States is considered a market economy where consumers and producers determine what’s sold and produced. Producers own what they make and decide their own prices, while consumers own what they buy and decide how much they’re willing to pay.
