Question 1

According to the Quantity Theory of Money, which equation best represents the relationship between money supply, velocity, price level, and output?

Accepted Answer

$$ M 	imes V = P 	imes Y $$

Question 2

In the IS-LM model, what does a rightward shift of the IS curve indicate?

Accepted Answer

An increase in aggregate demand due to higher government spending or investment

Question 3

Which of the following would cause the LM curve to shift to the right?

Accepted Answer

An increase in the money supply

Question 4

Refer to the diagram provided. In the left panel, what does the movement from $$ M^d_1$(Y_1$)  to$$ $$ M^d_2$(Y_2$) $$ represent?

Accepted Answer

An increase in income leading to higher demand for money at each interest rate

Question 5

Which of the following best describes the equilibrium in the IS-LM model?

Accepted Answer

The point where the goods market and money market are both in equilibrium

Question 6

If the central bank increases the money supply while the government increases taxes, what is the likely effect on the IS-LM equilibrium?

Accepted Answer

The LM curve shifts right and the IS curve shifts left

Question 7

Which of the following is NOT a factor that shifts the IS curve?

Accepted Answer

Change in the money supply

Question 8

According to the Laffer Curve, what happens to tax revenue if the tax rate is increased beyond the optimal rate $$ T^* $$?

Accepted Answer

Tax revenue decreases

Question 9

Which policy is most closely associated with supply-side economics?

Accepted Answer

Reducing marginal tax rates to encourage investment

Question 10

If the marginal propensity to consume (MPC) increases, what is the effect on the IS curve?

Accepted Answer

The IS curve becomes steeper

Question 11

Which of the following best explains why the LM curve slopes upward?

Accepted Answer

As income increases, the demand for money increases, requiring a higher interest rate to maintain equilibrium

Question 12

A country experiences a technological innovation that boosts productivity. What is the likely effect on the IS curve?

Accepted Answer

The IS curve shifts to the right

Question 13

Which of the following would make the LM curve steeper?

Accepted Answer

A higher income sensitivity of money demand

Question 14

If the price level increases while the nominal money supply remains constant, what happens to the LM curve?

Accepted Answer

The LM curve shifts to the left

Question 15

Which of the following is a criticism of the Laffer Curve?

Accepted Answer

It oversimplifies tax systems by using a single tax rate

Question 16

Suppose the government implements a policy that increases both government spending and the money supply. What is the likely effect on the IS-LM equilibrium?

Accepted Answer

Both IS and LM curves shift to the right, increasing income and possibly interest rates

Question 17

Which of the following is a key difference between supply-side and demand-side economics?

Accepted Answer

Supply-side focuses on increasing productive capacity, while demand-side focuses on boosting aggregate demand

Question 18

If the central bank expects higher future interest rates, how might this affect the LM curve today?

Accepted Answer

People may hold less money now, shifting the LM curve to the right

Question 19

Which of the following best describes the arithmetic effect of a tax cut according to the Laffer Curve?

Accepted Answer

A tax cut immediately reduces government tax revenue

Question 20

Which of the following is an example of a supply-side policy?

Accepted Answer

Investment in education and infrastructure
