QUESTION 4 GDP is a measure of O the total of wealth held by all residents in a nation at a given point in time. O a nation's production of final goods and services in a given period of time. O the amount of resources available in a nation at a given point in time. QUESTION 5 In 2015, the United States imported more than it exported. As a result, the sum of consumption plus investment plus government purchases O is greater than U.S. GDP in 2015. O is less than U.S. GDP in 2015. O equals U.S. GDP in 2015. QUESTION 6 Consider a hypothetical one-good economy that only produces staplers. In 2018 (the base year), 100 staplers were produced and sold at a market price of $2 each. In 2019, 200 staplers were produced and sold at a market price of $1 each. Select the correct answer among the choices below. (Hint: For a one-good economy, the CPI in 2019 doesn't depend on the market basket; i.e., whatever market basket you work with, you'll arrive at the same value of the 2019 CPI. Thus, this question doesn't specify a market basket.) The CPI in 2019 is less than the GDP Deflator in 2019. The CPI in 2019 equals the GDP Deflator in 2019. The CPI in 2019 is greater than the GDP Deflator in 2019
