5-Frictional unemployment is the unemployment due to the constant turnover of individuals in given jobs and in a constant change in job opportunities.

6-Structural unemployment occurs because of a mismatch between the characteristics of the supply of labor and the demand for labor.

7-Consumer Price Index measures the average cost of goods and services that are bought by the typical American household.

8-Gross domestic product measured from the income side is equal to the sum of the four components: consumption, investment, government purchases, and net exports.

9-Double counting is the error that would arise in estimating the nation's output by adding all sales of all firms.
