Quizplus · Accepted Answer

An increase in the real interest rate will reduce investment spending, as it becomes more expensive for firms to borrow funds for investment purposes. This decrease in investment will shift the aggregate demand curve to the left, lowering the equilibrium level of GDP. From the table, we can see that a $100 billion decrease in investment spending reduces GDP by $400 billion, so a $300 billion decrease in investment (due to the interest rate increase) will reduce GDP by $1,200 billion (3 x $400 billion). Therefore, the correct answer is C, which represents a $400 billion decrease in GDP due to the interest rate increase.
