The Federal Reserve System was established in:
1913.
Fiscal Policy — End of Chapter Problem Most macroeconomists believe that it is a good thing that taxes act as automatic stabilizers and lower the size of the multiplier. However, a smaller multiplier means that changes in government purchases of goods and services, government transfers, or taxes necessary to close inflationary or recessionary gaps are larger. How can you explain this apparent inconsistency?
Automatic stabilizers dampen the business cycle. Any change in autonomous spending would result in a smaller inflationary or recessionary gap. Although the effect of discretionary fiscal policy would be reduced, the need for discretionary fiscal policy would also be reduced.
Identify how planned investment will change in each scenario. Airwings, a commercial airline manufacturer, becomes optimistic about economic conditions after seeing reports of strong growth in consumer spending. The Federal Reserve announces an end to accommodative monetary policy, and is now implementing policy tools that will increase the real interest rate. In an effort to reduce constant budget deficits, Congress announces plans to increase the corporate income tax rate. A major recession has reduced consumption spending, which has hurt profit levels for Aston-Benz, a high-end car manufacturer.
Due to Airwings, planned investment increase. Due to the Fed, planned investment decrease. Due to the Congress, planned investment decrease. Due to the recession, planned investment decrease.

Income and Expenditure — End of Chapter Problem The Bureau of Economic Analysis reported that, in real terms, overall consumer spending increased by $335.5 billion in 2019. a. If the marginal propensity to consume is 0.50, by how much will real GDP change in response? Enter your answer in billions of dollars. b. If there are no changes in autonomous spending other than the increase in consumer spending described in part a, and unplanned inventory investment, 𝐼𝑢𝑛𝑝𝑙𝑎𝑛𝑛𝑒𝑑, decreases by $100 billion, what is the change in real GDP? Enter your answer in billions of dollars. c. GDP at the end of 2019 was $18,638.2 billion. If GDP were to increase by the amount calculated in part b, what would be the percentage increase in GDP? Round your answer to the nearest hundredth of a percent.
Change in GDP: $ 671 billion (1/1−0.50×$335.5 billion = $671 billion) Change in GDP: $ 471 billion (1/1−0.50×($335.5 billion−$100 billion)= $471 billion) Percentage change in GDP: 2.53% ($471 billion/$18,638.2 billion×100=2.53%)

What was the main financial problem that the government of Greece faced in 2009?
It had a large budget deficit, but most of its creditors were unwilling to make loans to Greece or charged extremely high interest rates to compensate them for the risk of loss.
Calculate the values for each of the questions. Assume that in each country there are no taxes, international trade, or inflation and that interest rates are fixed. The Italian government decides to stimulate the economy by sending checks worth $70 billion to Italian consumers. If the government spending multiplier is 1.5, calculate the MPC to determine the final change in Italy's real GDP due to the transfer. Please give your answer as a whole number in billions of dollars. The Greek government decides to introduce new austerity measures, which reduce government direct spending by $16 billion. Greece has a marginal propensity to consume of 0.6. What will be the final change in real GDP as a result of this decreased spending? Please give your answer as a whole number in billions of dollars. The Japanese government decides to stimulate the economy by increasing direct spending by $70 billion.

You are Chair of the Federal Reserve Board. In your meeting with the Federal Open Market Committee, the committee unanimously votes to increase the money supply using open market operations (OMOs). During the press conference after the meeting, a reporter asks you to explain what OMOs are and how you will use them to increase the money supply. You reply that
OMOs are the selling and buying of government securities. The money supply increases when purchasing occurs and contracts when selling occurs. OMOs work by changing the amount of excess reserves available in the banking system.

Fiscal Policy — End of Chapter Problem In the following case, either a recessionary or inflationary gap exists. Assume that the aggregate supply curve is horizontal so that the change in real GDP arising from a shift of the aggregate demand curve equals the size of the shift of the curve. Calculate the magnitude of both the change in government purchases of goods and services and the change in government transfers necessary to close the gap. Real GDP equals $100 billion, potential output equals $160 billion, and the marginal propensity to consume is 0.75. The economy faces ________ gap. To close the gap, government spending and/or transfers would need to __________. Spending would need to change by $ ________ billion to close the gap. Transfers would need to change by $ ___________ billion to close the gap.

Fiscal Policy — End of Chapter Problem Unlike households, governments are often able to sustain large debts. For example, in 2019, the U.S. government's total debt reached $21.2 trillion, approximately equal to 105.3% of GDP. At the time, according to the U.S. Treasury, the average interest rate paid by the government on its debt was 1.3%. However, running budget deficits becomes hard when very large debts are outstanding. a. Calculate the dollar cost of the annual interest on the government's total debt, assuming the interest rate and debt figures previously cited. Enter your answer in billions of dollars, and round to the nearest tenth. b. If the government operates on a balanced budget before interest payments are taken into account, at what rate must GDP grow for the debt-GDP ratio to remain unchanged? Enter your answer as a percentage and round to the nearest tenth of a percent. c. Calculate the total increase in national debt if the government incurs a deficit of $600 billion in 2020. Enter your answer in billions of dollars and round to the nearest tenth. d. At what rate would GDP have to grow in order for the debt-GDP ratio to remain unchanged when the deficit in 2020 is $600 billion? Enter your answer as a percentage and round your answer to the nearest hundredth of a percent. e. Why is the debt-GDP ratio the preferred measure of a country's debt rather than the dollar value of the debt? Why is it important for a country to keep its debt-GDP ratio under control?
a. $275.6 b. 1.3 c. $875.6 d. 4.13% e. The size of an economy, measured by its GDP, determines a government's ability to repay debt through taxes. The debt-GDP ratio is a more accurate reflection of how burdened a country is by debt than the dollar value of the debt. A government should keep the debt-GDP ratio under control to keep itself from being overburdened by debt.
Income and Expenditure — End of Chapter Problem The U.S. economy slowed significantly in early 2008, and policymakers were extremely concerned about growth. To boost the economy, Congress passed relief packages (the Economic Stimulus Act of 2008 and the American Recovery and Reinvestment Act of 2009) that, combined, would deliver about $700 billion in government spending to the economy. Assume, for the sake of argument, that this spending took the form of payments made directly to consumers with the objective of boosting the economy by increasing the disposable income of American consumers. a. If the marginal propensity to consume (MPC) in the United States is 0.5, the initial change in aggregate consumer spending as a consequence of this policy measure would be ____________. The resulting change in real GDP due only to the change in consumer spending would be __________. b. Using the accompanying graph, illustrate the effect on real GDP by shifting the planned aggregate expenditure curve. Show the effect of the autonomous policy change on the equilibrium by moving the equilibrium point.

Fiscal Policy — End of Chapter Problem During a 2008 interview, then-German Finance Minister Peer Steinbrueck said, "We have to watch out that in Europe and beyond, nothing like a combination of downward economic [growth] and high inflation rates emerge—something that experts call stagflation."

a. AD shift right, E3 intersect with AD, SRAS2, and LRAS b. AD shift left. E3 intersect with AD and SRAS2 c.
