Following Keynesian economics, the federal government can move the economy to full employment at point E₂ by: increasing government tax revenue by approximately $33 billion. B decreasing government tax revenue by $100 billion. increasing government tax revenue by $100 billion. decreasing government tax revenue by $750 billion. decreasing government tax revenue by approximately $33 billion.

You are studying an economy with an income tax rate, t1, of 32%and an MPS of 0.3. It is currently suffering from a “recessionary gap” of $500 m. (i.e., Eqm Y<Y full employment, FE, aka Yn). Make the necessary calculations for the topolicythat it should institute; who does what? Provide the full name of this policy. Compare this economy to one without income taxes to explain the term “automatic stabilizer.”[Hint: Let I change and compare the I multipliers in each of these economies.]  \

uèstion 21 pounts The economy is in a recession. The government enacts a policy to increase the real GDP by $10 billion. The MPS is 0.2. Assuming that the agggregate supply curve is horizontal across the range of GDP being considered, by how much should the government change spending or taxes in order to achieve its objective?

Question 3 of 16 Income and consumption changes for five people are shown in the table. Given this information, rank the marginal propensities to consume (MPC) for the five people from largest to smallest.

2. For simplicity, we normally treat aggregate tax payments (T) as determined by politics or other factors unrelated to output. However, suppose that aggregate tax payments are proportional to income. That is, T=t·Y, where tis the marginal tax rate and is between o and 1. a. How, if at all, would this change in our assumptions affect the Keynesian cross diagram? b. Would this change increase, decrease, or have no impact on the multiplier effect, or is it not possible to tell? (That is, how would the effect of a given vertical shift of the planned expenditure line compare with what it was before?)

Consider an economy that is operating atthe full-employment level of real GDP.Assuming the MPC is 0.90, predict the effect onthe economy of a $50 billion increase in governmentspending balanced by a $50 billionincrease in taxes.

An inflationary gap is how much GDP needs to decrease from the current GDP to maintain employment while avoiding inflation. Let us say that we are experiencing an inflationary gap of $200 million.  The government decides to increase taxes.  Assume that the MPC equals .80. What will be the tax increase?

During the 1930s the U.S. entered the Great Depression. During the Great depression investment fell from a yearly rate of $16.7 billion to $1.7 billion. In 1932, President Hoover increased income taxes.  Assume the MPC is .92 C). If  the AD shortfall in 1934 was $300 billion, what change in government expenditures on goods and services (G) would you have recommended to restore full-employment?  D). If the AD shortfall in 1934 was $300 billion, what change in  income/transfer payments would you have recommended ? E). If the AD shortfall in 1934 was $300 billion, what change in income taxes would you have recommended ?

The graph below depicts an economy where a decline in aggregate demand has caused a recession. Assume the government decides to conduct fiscal policy by increasing government purchases to reduce the burden of this recession.

How much does aggregate demand need to change to restore the economy to its long-run equilibrium? billion B b. If the MPC is 0.6, how much does government purchases need to change to shift aggregate demand by the amount you found in part a? Suppose instead that the MPC is 0.75. c. How much does aggregate demand and government purchases need to change to restore the economy to its long-run equilibrium? Aggregate demand needs to change by $ billion and government purchases need to change by $ billion.

Assume that government purchases decrease by $10 billion, with other factors held constant, including the price level. Calculate the change in the level of the real GDP demanded for each of the following values of the MPC. Then, calculate the change if the government, instead if reducing its purchases, increased autonomous net taxes by $10 billion.  a. 0.9  b. 0.8  c. 0.75  d. 0.6
