GDP - Gross Domestic Product GDP and Economic Growth Questions and Answers

Question 1

If a country's real GDP per capita is growing at a constant rate of 2.5% per year, approximately how many years will it take for its real GDP per capita to double?

Accepted Answer

28 years

Answer

The 'Rule of 70' is a useful approximation to estimate the doubling time for a variable growing at a constant rate. The formula is: Doubling Time ≈ 70 / (Annual Growth Rate). In this case, 70 / 2.5 = 28 years.

Question 2

A domestic manufacturer produces $1 million worth of goods in a year. They sell $800,000 worth to domestic consumers and add the remaining $200,000 worth to their warehouse. How is this accounted for in GDP using the expenditure approach (Y = C + I + G + NX)?

Accepted Answer

$800,000 is added to Consumption (C), and $200,000 is added to Investment (I).

Answer

In the expenditure approach to calculating GDP, the $800,000 sold to households is counted as Personal Consumption Expenditures (C). The $200,000 of unsold goods is considered an increase in private inventories, which is a component of Gross Private Domestic Investment (I). Thus, the full $1 million value of production is captured in GDP.

Question 3

Which of the following is considered the most critical driver of sustained, long-run increases in a country's standard of living?

Accepted Answer

Technological progress.

Answer

While capital accumulation and government spending contribute to growth, technological progress is the main driver of long-run growth and increased standards of living. It allows an economy to produce more output from the same or fewer inputs, overcoming the limitations of diminishing returns that affect capital and labor accumulation alone.

Question 4

An economy is operating where its actual real GDP is significantly lower than its potential GDP. This situation is best described as a(n):

Accepted Answer

Recessionary gap

Answer

A recessionary gap occurs when the actual output (real GDP) of an economy is less than its potential output, indicating that resources like labor and capital are underutilized. This is characteristic of an economic downturn or recession.

Question 5

Which of the following institutional factors is most fundamental for encouraging the private investment and innovation necessary for long-term economic growth?

Accepted Answer

Well-defined and legally enforced property rights.

Answer

Well-defined and enforced property rights are a crucial institutional foundation for economic growth. They give individuals and firms the confidence that they can own and benefit from their investments, which provides a powerful incentive for capital accumulation, innovation, and efficient resource allocation.
