Which of the following is included when calculating a country's gross domestic product (GDP)?

Gross domestic product (GDP) is a measure of the total economic activity in a country. It is calculated by adding up the market value of all the final goods and services produced within a country’s borders in a given period of time, usually a year or a quarter. Final goods and services are those that are sold to the end users, such as consumers, businesses, or the government, and are not used as inputs for further production. For example, a loaf of bread sold to a consumer is a final good, but the flour used to make the bread is not. The market value of goods and services is the price that buyers are willing to pay for them in the market. This reflects the value added by the producers at each stage of production and avoids double counting. For example, if a farmer sells wheat for $10 to a miller, who then sells flour for $20 to a baker, who then sells bread for $30 to a consumer, the value added at each stage is $10, $10, and $10, respectively. The total value added is $30, which is equal to the market value of the final good (bread). Therefore, GDP only includes the market value of final goods and services and excludes intermediate goods and services.
