Suppose that aggregate demand increases such that the amount of real output demanded rises by \$7 billion at each price level.

a. By what percentage will the price level increase? percent.

Will this inflation be demand-pull inflation or will it be cost-push inflation? (Click to select) Cost-push inflation Demand-pull inflation.

b. If potential real GDP (that is, full-employment GDP) is \$510 billion, what will be the size of the positive GDP gap after the change in aggregate demand? \$ billion.

c. If the government wants to use fiscal policy to counter the resulting inflation without changing tax rates, would it increase government spending or decrease it? (Click to select)Decrease Increase.

3 Suppose that a country has no public debt in year 1 but experiences a budget deficit of \$40 billion in year 2, a budget deficit of \$20 billion in year 3, a budget surplus of \$10 billion in year 4, and a budget deficit of \$2 billion in year 5.

a. What is the absolute size of its public debt in year 5?

Instructions: Enter your answer as a whole number. Do not include a plus or minus sign.

Public Debt = \$ billion.

b. If its real GDP in year 5 is \$104 billion, what is this country’s public debt as a percentage of real GDP in year 5?

Public Debt = percent.

4. 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 \$150 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?

\$ billion.
