Several European countries spend less time working and more time on leisure activities than the United States. How is this greater leisure time accounted for in gross domestic product measurements?

The value of Leisure time is not included in GDP.

Explanation:

Gross domestic product or GDP includes the value of final goods and services produced in an economy in a year. It does not include the value of intermediate goods to prevent double counting. It also does not include the value of second-hand goods.

The value of pollution, crime, leisure, etc. are also not included as they are difficult to express in monetary terms.
