Answer to Problem 1QQ

Option ‘d’ is the correct answer.

Explanation of Solution

Option (d):

The increases in equilibrium income due to an increase in government purchase can be calculated as follows:

First, calculate the government spending multiplier.

The mulitiplier=1(1MPC)=1(123)=3

Therefore, the value of government spending multiplier is 3.

Now, the increase in equilibrium income due to an increase in government purchase can be calculated as follows:

Changes in income=$120×3=$360

Therefore, the equilibrium income increases by $360 million.

Thus option (d) is correct.

Option (a):

The increases in equilibrium income due to an increase in government purchase can be calculated as follows:

First, calculate the government spending multiplier.

The mulitiplier=1(1MPC)=1(123)=3

Therefore, the value of government spending multiplier is 3.

Now, the increase in equilibrium income due to an increase in government purchase can be calculated as follows:

Changes in income=$120×3=$360

Therefore, the equilibrium income increases by $360 million.

Thus option (a) is incorrect.

Option (b):

The increases in equilibrium income due to an increase in government purchase can be calculated as follows:

First, calculate the government spending multiplier.

The mulitiplier=1(1MPC)=1(123)=3

Therefore, the value of government spending multiplier is 3.

Now, the increase in equilibrium income due to an increase in government purchase can be calculated as follows:

Changes in income=$120×3=$360

Therefore, the equilibrium income increases by $360 million.

Thus, option (b) is incorrect.

Option (c):

The increase in equilibrium income due to an increase in government purchase can be calculated as follows:

First, calculate the government spending multiplier.

The mulitiplier=1(1MPC)=1(123)=3

Therefore, the value of government spending multiplier is 3.

Now, the increase in equilibrium income due to an increase in government purchase can be calculated as follows:

Changes in income=$120×3=$360

Therefore, the equilibrium income increases by $360 million.

Thus option (c) is incorrect.

7. Suppose in the Simple Keynesian model that the marginal propensity to consume is b = 0.75. If both taxes, T, and government spending, G, are increased by $400, then equilibrium Y O decreases by $1,200. increases by $1.600. increases by $400. neither increases nor decreases. none of the other options.
Suppose the marginal propensity to consume is 0.6. Use the Keynesian Cross model to predict the impact on equilibrium income of each of the following policies. State the direction of the change and give a formula for the size of the impact.   a. an increase in government purchases of $100billion b. an increase in taxes of $100 billion c. a $100 billion increase in both government purchases and taxes?
Suppose that the government increases its spending by 50$. If the MPC (marginal propensity to consume) in the economy is 0.5, then according to the Keynesian cross output will a. Increase by 70$ b. Decrease by 100 c. Increase by 100$ d. Not change
