In January, the interest rate is 5 percent and firms borrow $50 billion per month for investment projects. In February, the Federal government doubles its monthly borrowing from $25 billion to $50 billion. That drives the interest rate up to 7 percent. As a result, firms cut back their borrowing to only $30 billion per month. Which of the following is true?
A. There is a crowding-out effect of $20 billion.
B. There is a crowding-out effect of $25 billion.
C. There is no crowding-out effect because both the government and firms are still borrowing a lot.
D. There is no crowding-out effect because the government’s increase in borrowing exceeds firms' decrease in borrowing.
