Question 13

If the Bank of Canada wants to decrease the money supply, which of the following actions would it most likely take?

Accepted Answer

Question 14

Which of the following best explains why the aggregate demand curve is downward sloping?

Accepted Answer

As the price level falls, the purchasing power of money increases, leading to higher real spending.

Question 15

A bond has a face value of $\$1,000$ and pays $\$50$ per year in interest. If the market interest rate rises to $6\%$, what happens to the price of the bond?

Accepted Answer

The price of the bond falls below $\$1,000$.

Question 16

If the marginal propensity to import (MPM) is $0.2$ and the marginal propensity to consume (MPC) is $0.7$, what is the value of the simple multiplier in an open economy with no taxes?

Accepted Answer

$\frac{1}{1 - MPC + MPM} = \frac{1}{1 - 0.7 + 0.2} = \frac{1}{0.5} = 2$
