The economy of the United States is a mixed economy. A mixed economy exists when the market and the government allocates some resources. The health of the economy of the United States is measured by three major indicators, which include the gross domestic product, the unemployment rate, and price indices. The gross domestic product is the total value of goods and services produced in a country in a year. The unemployment rate measures how many people aged 16 or older are out of work. Finally, price indices, which include the consumer price index (CPI) and the producer price index (PPI), measure the pace of inflation and prices at the wholesale level. All of these indicators help us determine the health of the economy in the United States.
