Using AD/AS analysis [graph this], explain what effect this policy will have on each of the following. (i) AD, & thus output & employment (ii) The price level (iii) The interest rate

Answers:Answers: (i) The increase in personal taxes will decrease DI, which will decrease C, which will decrease AD, which will decrease output and employmentdecrease output and employment.(ii) The decrease in AD will result in a lower equilibrium [AD1 to AD2 & E1 to E2] and a lower price levellower price level.(iii) The increase in personal taxes results in more tax revenue v. government spending, which decreases the demand for money in the LFM & a decrease in interest ratesdecrease in interest rates.

(c) The level of exports

Answers:Answers: (a) As shown (graph), nominal wage rates rising faster than labor productivity would decrease the AS curve from AS1 to AS2. The decrease in AS would change equilibrium from E1 to E2, which would result in a higher general price level.higher general price level.

Clark Consulting has a DDof $5,000. Adding these two together gives a TMS of $50,000TMS of $50,000. (c) If banks keep some of the deposit as ERbanks keep some of the deposit as ER, how will this influence the change in the MSchange in the MS that was determined in part (b)(II)? Explain.Answer:Answer: If the bank doesn’t loan out all of the $4,500 ER, then the1st loan would not be as much as $4,500not be as much as $4,500, therefore reducing PMC. (d) If the public decidespublic decides to to hold some money in the form of currencyhold some money in the form of currencyrather than in demand deposits, how will this influence the change inchange inthe money supplythe money supply that was determined in part (b)(ii)? Explain.

Answer:Answer: If the public gets the loan and holds part of it as currency, thenthis is a leakage in the PMC of the banking system. If the person who takesthe $4,500 loan from First Generation Bank takes $500 in cash, then only$4,000 gets deposited in the next bank, thus reducing the PMCreducing the PMC of the system.

1. Assume the U.S. economy is operating at full-employment output and the government has a balanced budget. A drop in consumer confidence reduces consumption spending, causing the economy to enter into a recessionrecession.

(a) Using a correctly labeled graph of the short-run Phillips curve, show the effect of the decrease in consumption spending. Label the initial position “A”“A” and the new position “B”“B”.

(b) What is the impact of the recessionrecession on the federal budget? Explain.

Answer to 1. (b): Answer to 1. (b): The decrease in consumption would result in a decrease in AD and a decrease in GDP.The decrease in consumption would result in a decrease in AD and a decrease in GDP. This would result in an increase in unemployment and an increase in transfer payments.This would result in an increase in unemployment and an increase in transfer payments. Due to the job losses, there would be a decrease in tax revenues, resulting in an increaseDue to the job losses, there would be a decrease in tax revenues, resulting in an increase in government red ink for the federal budget. So in government red ink for the federal budget. So a a federal budget deficit would increase federal budget deficit would increase or a federal budget surplus would decrease. or a federal budget surplus would decrease.

(c) Assume current real GDP falls short of full-employment output by $500 billion and the MPC is 0.8. (i) Calculate the minimum increase in government spending that could bring about full employment. Answer to 1. (c) (i):Answer to 1. (c) (i):

The expenditure multiplier [The expenditure multiplier [MMEE] would be 5 [1/.2 = ] would be 5 [1/.2 = MMEE of 5]. Because current output of 5]. Because current output falls short by $500 billion, it would take a minimum increase in government spendingfalls short by $500 billion, it would take a minimum increase in government spending of $100 billion to get to full employment. [5 X $100 = $500]of $100 billion to get to full employment. [5 X $100 = $500]

(ii) Assume that instead of increasing government spending, the government decides to reduce personal income taxes. Will the reduction in personal income taxes required to achieve full employment be larger than or smaller than the government spending change you calculated in part (c) (i)? Explain why. Answer to 1. (c) (ii): Answer to 1. (c) (ii):

Because the tax multiplier [Because the tax multiplier [MMTT] is smaller, or [MPC/MPS = .8/.2 = 4], it will take a larger] is smaller, or [MPC/MPS = .8/.2 = 4], it will take a larger tax cut then the increase in government spending. Because current output is $500 bil.tax cut then the increase in government spending. Because current output is $500 bil.

short of FE Y, and the short of FE Y, and the MMTT is 4, it would take a tax cut of $125 billion. [4 X $125 = $500] is 4, it would take a tax cut of $125 billion. [4 X $125 = $500]

3. The PPCs for Artland & Rayland are shown. Using equal amounts of resources, Artland can produce 600 hats or 300 bicycles, & Rayland can produce1,200 hats or 300 bicycles.(a)Calculate the opportunity cost of a bicycle in Artland.

(b) If the two countries specialize and trade, which country will import bicycles? Explain.

(c) If the terms of trade are 5 hats for 1 bicycle, would trade be advantageous for each of the following? (i) Artland (ii) Rayland

(d) If productivity in Artland triples, which country has the comparative advantage in the production of hats?

Answer to 3. (a):Answer to 3. (a): The Domestic Comparative (opportunity cost) of The Domestic Comparative (opportunity cost) of a bicycle a bicycle in Artland is 2 units of hats. [1 bicycle = 2 hats or 600/300=2] in Artland is 2 units of hats. [1 bicycle = 2 hats or 600/300=2]

Answer to 3. (b):Answer to 3. (b): Rayland will import bicycles. Domestically, they have to giveRayland will import bicycles. Domestically, they have to give up 4 hats to get a bicycle but with trade they have to give upup 4 hats to get a bicycle but with trade they have to give up only 3 hats. only 3 hats.

DCC: Rayland DCC: ArtlandDCC: Rayland DCC: Artland1 B = 4 H1 B = 4 H 1 B = 2 H 1 B = 2 H¼ B= 1 H¼ B= 1 H ½ B= 1 H ½ B= 1 H

Answer to 3. (c) (i): Answer to 3. (c) (i): Yes, 5 hats Yes, 5 hats is is better better than than 2 hats they are getting domestically. 2 hats they are getting domestically.

Answer to 3. (d): 300 bicycles would become 900 and 600 hats would become 1,800, so theAnswer to 3. (d): 300 bicycles would become 900 and 600 hats would become 1,800, so the DCC would still be 1 bicycle = 2 hats, same as before. Rayland still has a C.A. in hats. DCC would still be 1 bicycle = 2 hats, same as before. Rayland still has a C.A. in hats.

Answer to 3. (c) (ii): Answer to 3. (c) (ii): No, Rayland is going to export hats so opportunity costNo, Rayland is going to export hats so opportunity costis ¼ bicycle. So 1/5 of a bicycle would not benefit them. is ¼ bicycle. So 1/5 of a bicycle would not benefit them.
