Q: Suppose the nominal exchange rate between the US dollar and the euro is $$1.20/\text{euro}$$, the US price level is $$120$$, and the European price level is $$100. $$What is the real exchange rate?

$$1.20 \times \frac{120}{100} = 1.44$$

Question 1

Suppose the real GDP of a country grows at a constant annual rate of 5%. According to the Rule of 70, approximately how many years will it take for the country's real GDP to double?

Question 2

Which of the following best describes the difference between human capital and technology as determinants of productivity?

Accepted Answer

Human capital refers to the knowledge and skills of workers, while technology refers to the processes used to turn inputs into outputs.

Question 3

If the reserve ratio in a fractional reserve banking system is 20%, what is the value of the money multiplier?

Question 4

Accepted Answer

$$(Y - T - C) + (T - G) = (10,000 - 2,000 - 6,000) + (2,000 - 1,500) = 2,000 + 500 = 2,500$$
