Problem
Suppose that American firms become more optimistic and decide to increase investment expenditure today in new factories and office space.
a. How will this increase in investment affect output, interest rates, and the current account?
b. Now repeat part (a), assuming that domestic investment is very responsive to the interest rate so that U.S. firms will cancel most of their new investment plans if the interest rate rises. How will this affect the answer you gave previously?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
