Question

Assume there are no prospective investment projects (I) that will yield an expected rate of return (r) of 25 percent or more, but there are $5 billion of investment opportunities with an expected rate of return between 20 and 25 percent, an additional $5 billion between 15 and 20 percent, and so on. If the real interest rate is 15 percent in this economy, the aggregate amount of investment will be

Answer 1

Answer:

$10 billion

Explanation:

The aggregate amount of investment = the $5 billion that yield a 20-25% rate of return + the $5 billion that yield a 15-20% rate of return.

Both amounts are included because their rates of return are higher than the current interest rate in the economy (15%).
