Q: Suppose a bank receives a deposit of $1,000 and the required reserve ratio is 10%. What is the maximum potential increase in the money supply as a result of this deposit, using the simple deposit multiplier formula?

$$\n$$\frac{1}{0.10} = 10$$, so 1$$,000 \times 10 = $$10,000$$

Q: If the government increases spending by $100 million and the marginal propensity to consume (MPC) is 0.8, what is the total change in GDP using the government spending multiplier?

$$\n$$Multiplier = \frac{1}{1-0.8} = 5$$, so 100$$ \text{ million} \times 5 = 500 \text{ million}$

Question 1

Which of the following best describes the primary function of money in an economy?

Accepted Answer

Money serves as a store of value, a unit of account, and a medium of exchange.

Question 2

Suppose a bank receives a deposit of $1,000 and the required reserve ratio is 10%. What is the maximum potential increase in the money supply as a result of this deposit, using the simple deposit multiplier formula?

Accepted Answer

$$
$$\frac{1}{0.10} = 10$$, so 1$$,000 	imes 10 = $$10,000$$

Question 3

According to the quantity theory of money, if the money supply increases by 5% and velocity and real output remain constant, what is the expected change in the price level?

Accepted Answer

The price level will increase by 5%.

Question 4

What is the short-run implication of the Phillips curve for monetary policy?

Accepted Answer

There is a trade-off between inflation and unemployment in the short run.

Question 5

Which of the following is NOT a tool of monetary policy?

Accepted Answer

Government spending on infrastructure.

Question 6

In the AD-AS model, what is the effect of an expansionary monetary policy?

Accepted Answer

The aggregate demand curve shifts to the right.

Question 7

Which of the following best describes a contractionary monetary policy?

Accepted Answer

A policy that reduces the money supply to increase interest rates and decrease inflation.

Question 8

Which of the following is an example of discretionary fiscal policy?

Accepted Answer

A government passes a new stimulus package in response to a recession.

Question 9

What is the main difference between automatic stabilizers and discretionary fiscal policy?

Accepted Answer

Automatic stabilizers work without new government action, while discretionary policy requires deliberate legislative changes.

Question 10

If the government increases spending by $100 million and the marginal propensity to consume (MPC) is 0.8, what is the total change in GDP using the government spending multiplier?

Accepted Answer

$$
$$Multiplier = \frac{1}{1-0.8} = 5$$, so 100$$ 	ext{ million} 	imes 5 = 500 	ext{ million}$

Question 11

Which of the following best describes the concept of 'crowding out' in fiscal policy?

Accepted Answer

Government borrowing increases interest rates, reducing private investment.

Question 12

If the government increases taxes by $50 million and the MPC is 0.75, what is the total change in GDP using the tax multiplier?

Accepted Answer

$$
$$Tax\ multiplier = -\frac{MPC}{1-MPC} = -\frac{0.75}{0.25} = -3$$, so -3$$ 	imes 50 = -150 	ext{ million}$

Question 13

Which of the following is an example of an automatic stabilizer?

Accepted Answer

Unemployment insurance payments that increase during a recession.

Question 14

What is the balanced-budget multiplier, and what is its value?

Accepted Answer

It is the effect on GDP when government spending and taxes increase by the same amount; its value is 1.

Question 15

Which of the following best describes unconventional fiscal policy?

Accepted Answer

Policies that focus on the supply side, such as tax simplification or deregulation.

Question 16

If the marginal propensity to consume (MPC) is 0.6, what is the value of the government spending multiplier?

Accepted Answer

$$
$$Multiplier = \frac{1}{1-0.6} = 2.5$

Question 17

Which of the following statements about the AD-AS model is correct?

Accepted Answer

An increase in aggregate demand can lead to higher output and higher prices in the short run.

Question 18

What is the main goal of fiscal policy?

Accepted Answer

To influence aggregate demand and stabilize the economy.

Question 19

Which of the following best describes the concept of 'crowding out' in the context of government budget deficits?

Accepted Answer

Government borrowing raises interest rates, which can reduce private investment.

Question 20

If the supply side effects of a tax simplification policy are significant, what is the likely impact on the long-run aggregate supply (LRAS) curve?

Accepted Answer

The LRAS curve will shift to the right, indicating increased productive capacity.
