Question

Suppose that the investment demand curve in a certain economy is such that investment declines by $130 billion for every 1 percentage point increase in the real interest rate. Also, suppose that the investment demand curve shifts rightward by $190 billion at each real interest rate for every 1 percentage point increase in the expected rate of return from investment. If stimulus spending (an expansionary fiscal policy) by government increases the real interest rate by 2 percentage points, but also raises the expected rate of return on investment by 1 percentage point, how much investment, if any, will be crowded out?

Answer 1

Answer:

50 billion

Explanation:

Investment declines by $130 billion for every 1 percentage point increase in the real interest rate.

Decline in Investment because of higher real interest rate:

= 2 × 100

= $200 billion

Increase in Investment because of higher expected rate of return:

= 1 × 150

= 150 billion

Total decline in investment:

= -200 + 150

= 50 billion

Therefore, 50 billion of investment will be crowding out.
