2002 AP Macro Exam FRQ #1

2002 AP Micro Exam (Question 1)


(a) Identify one fiscal policy action that Congress might initiate to decrease the unemployment rate.

Expansionary fiscal policy would decrease unemployment either Government Spending increase or Tax decrease.

Answer - 

(b) Assume the policy you identified in part (a) reduced unemployment, but the economy is still operating below full employment. Using a CLG of aggregate demand/aggregate supply, show and explain, how the action you identified would affect each of the following

(i) Price
(ii) Output

Expansionary fiscal policy would increase output and the price level as Government spending will increase AD and thus output and will also increase the PL.


Answer - 

(c) Explain how the policy identified in part (a) would affect short-term interest rates.

Government Spending will increase the demand for loanable funds and therefore the Real interest rate will increase. Nominal interest rates are increased as the demand for money increases. Demand for money increases when incomes (Y) increase.



Answer - 


(d) Given the economy is still below full employment, identify the open market operation that the Federal reserve could implement to increase the money supply.

Monetary expansion = Open market operation = Buy Bonds

Answer - 

(e) Using a CLG, show and Explain, how an increase in the money supply will affect each of the following in the short run

(i) Short term interest rates
(ii) Output
(iii) Price levels



Money supply increases will decrease the nominal interest rates that will spur investment and consumption which will shift aggregate demand rightward increasing output and pushing up the price level. (Output & Price levels increase while Interest rates decrease)


Answer -

2015 AP Macroeconomics FRQ #1

2015 AP Macroeconomics FRQ #1
Crying because he waited and crammed for the AP 
and now recognises that it is just to much information.

Watch me answer it on youtube https://youtu.be/lBuO7Jpm_pI


(A) Economy is operating below full employment,,, Draw a CLG of LRAS, SRAS, AD.
You must understand that below full employment means a recession graph.

(B) Assume the FED targets a new Federal Funds Rate to reach full employment. Should the Federal Reserve  target a higher or lower Federal Funds Rate?

1st you need to know what the FED funds rate is, so,, of the cheat sheet.


A lower Fed. Funds rate will entice banks to borrow and loan money at a cheaper rate. This will stimulate more loaning in the economy thus more money creation and therefore will ultimately push AD higher toward full employment.

Answer - One point is earned for stating that the Federal Reserve should target a lower federal funds rate.

(C) Draw a graph of the Money market (nominal interest rates) and the effect that part B had on it,

A lower federal funds rate will increase the level of borrowing between banks and more money creation will occur increasing the MS (money supply) which will lower the nominal interest rates.

Answer - 


(D) The policy makers pursue a fiscal policy rather than a monetary policy in part (B). Assume that the marginal propensity to consume is 0.8 and the value of the recessionary gap is $300billion.

(i) If the government changes its spending without changing taxes to eliminate the recessionary gap, calculate the minimum change in spending that is required.

So if the MPC is 0.8 the multiplier is 5

You have to know these formulas.

If the MPC is 0.8 then the MPS is 0.2 as they both together must = 1

So, 1/0.2 = 5,, the multiplier is 5

This means that the amount that government spends to correct the recession will be multiplied by 5.

If there is a 300b recessionary gap,, the government must spend 60 billion dollars 
because 60b X 5 =  300b.

Answer - One point is earned for calculating the minimum required change in government spending:$60 billion ($300/5=$60) 

(ii) If the government changes taxes with our changing spending to eliminate the recessionary gap, will the minimum required  change in taxes be higher, lower or the same as the change in government spending in part (D)(i)?

If unclear about the difference between the spending and the taxing multipliers then check out this blog post that specifically addresses the issue.

If the government doesn't want to increase spending (expansionary policy) it can reduce taxes (expansionary policy) but it will have to decrease taxes by more than 60b.

Why? To reduce taxes by 60b does mean that 60b of disposable income is now available to be spent by consumers but but but some of that 60b will be saved and thus leaked out of the economy, thus reducing the multiplying of the amount. 

Answer - One point is earned for stating that the minimum required change in taxes will be greater than the minimum required change in government spending.  One point is earned for explaining that the tax multiplier (mpc/mps = 0.8/0.2 = 4) is smaller than the government spending multiplier (1/mps = 1/0.2 = 5) because part of the initial increase in disposable income caused by the decrease in income tax will be saved rather than spent. 

(E) Assume the government lowers income taxes to eliminate the recessionary gap. Will each of the following increase, decrease or stay the same?

(i) AD explain.

AD will increase. Obviously if the government reduces taxes citizen's disposable income will increase and therefor consumption and investment will increase driving AD up.

Answer - One point is earned for stating that aggregate demand will increase and for explaining that lower income tax rates will increase disposable income and/or consumption and investment. 

(ii) Long Run Aggregate Supply, Explain

(Answer 1) Long run aggregate supply will not be affected (stay the same) as in the future government will have to borrow to make up the lack of tax revenue that cutting taxes cost. This scenario never assumes that government would cut taxes spending as governments never do.

Think of the LRAS (Long run aggregate supply) curve as the PPC curve,, what shifts the PPC outward is Technology, population, more resources found or trade. People having money not taken from them (taxes) doesn't change the fact that government would have spent that money also.

Arguments aside,, (we must) if the citizens spend the money or the government does,, won't affect the LRAS curve.

Answer 1 - One point is earned for stating that long-run aggregate supply will stay the same because lowering income taxes will increase consumption and/or investment, or there is no change in inputs.

(Understand that I like answer 1 the best,,, but find the one you understand the best)

(Answer 2) Long run aggregate supply will (increase) as with reduction in taxes, disposable incomes will increase causing more consumption and investment into capital intensive projects, (think technology) and therefore people working smarter and producing more per capita,,, shifting out of the PPC.

Answer 2 - One point is earned for stating that long-run aggregate supply will (increase) in the long run because lowering taxes will increase savings and investment in physical capital, or because of increased incentives to work.

(Answer 3) Long run aggregate supply will (Decrease) as in the future government will have to borrow to make up the lack of tax revenue that cutting taxes cost. This scenario never assumes that government would cut taxes spending as governments never do. If the government borrows to make up the difference in tax cuts then interest rates rise discouraging investment and consumption (crowding out). 

Answer 3 - One point is earned for stating that long-run aggregate supply will (decrease) in the long run because lowering taxes leads to a crowding out of private investment.

2004 Macro FRQ #3 (FED Buys Bonds/ Reserve Requirements)

FED Buys Bonds (Money Supply)
So, lately I was stumped in class.

The 2004 Macro FRQ #3

A) As a result of the FED's action, what is the change in the money supply if the required reserve ratio is 100%??

Answer - If the RRR is 100%, the amount held by the bank in Required Reserves is all $5000 dollars. But  the thing is,, the FED dropped $5,000 into the market initially by buying the bonds. That is where the increase comes from (the initial purchase of bonds from the FED)


B) If the Required reserve ration is reduced to 10%, calculate the following.
(i) The maximum amount this bank could lend from this deposit.

If the required reserve is reduced to 10%, then that means the bank is required to keep in reserve 10% of the $5,000 dollars deposited. So .10 x 5,000 = $500 in Reserve
This means that $4,500 of the amount deposited is put in excess reserves that can be loaned out. 
Answer (i) - So, the maximum amount that can be loaned out from the initial deposit of $5,000 is $4,500.

The part below is where I had a bit of a brain-fart.
(ii) The maximum increase in the total money supply from the FED's purchase of bonds.
The maximum increase in the money supply is happening from two different actions.
1) The bank is able to loan out the $4,500 and that amount is multiplied throughout the economy. We calculate this as 1/RRR = 1/.1 = 10,, so the $4,500 x 10 = $45,000 increase in the money supply. This is the amount of money that the banks can increase the money supply by the deposit. BUT,, there is someone we forgot about.
2) The FED had increased the money supply by buying bonds from our friends at the Clark Consulting Service of $5,000. 

Answer - the maximum amount the money supply can be increased is $50,000,, $45,000 from the actions of the bank and $5,000 from the initial buying of bonds from Clarks.


C) If the bank keeps some of its excess reserves how will this influence the change in the money supply? 

Answer - if the banks don't use all of there excess reserves to loan out,, then the money supply will not be increased by as much as it could. It would be less than the $50,000 of maximum increase.


D) If the public decides to not put the cash into the banks how will this effect the money supply?

Answer - this is the same as question (C),, if people don't put their deposits in the bank,, then the money supply cannot be increased. If Clark had just kept the $5,000 in cash,, then the money supply would only have increased by $5,000,, no more.


College Board, I salute you.

Thanks, Jung-Sub

2014 AP Macro Exam FRQ question 2

2014 AP Macro Exam FRQ question 2


Watch me anser it here


2. The Federal Reserve can influence the supply of money.

(a) Assume the Federal Reserve targets a lower federal funds rate.
(i) What open market operation can the Federal Reserve use to achieve a lower target?

The Federal reserve has three tools at their control,,, OMO Open market operations (buying and/or selling bonds), reserve requirement (increase /decrease), discount rate (increase/decrease).
 1st you must know what the federal funds rate is -  cheat sheet.



The Federal Funds Rate is the interest rate that commercial banks charge one another in loaning out their excess reserves.

The example above shows an increasing Federal funds rate,, we want a decreasing Federal Funds rate.

Answer - if the Fed was to buy bonds,, the MS, increases and the Nom. IR, Nominal interest rate decreases,, thus lowering the rate of interest the commercial banks will charge each other in loaning out their excess reserves.

(ii) Given your answer to part (i) what will happen to the price of bonds.

If the Fed buys bonds,,, the price of bonds will increase.  The easiest way to understand this is to think about supply and demand,, demand for bonds goes up... price of bonds increase.

Better yet understand that interest rates and Bond Prices are inversely related.
FED Cheat Sheet here.
Answer - if the fed is buying bonds then the price of bonds is increasing.

(b) Using a correctly labeled graph of the money market, show the effect of the open market operation fro part (a) (i) on the nominal interest rates.

Cheat sheet - 

You must know how to draw and label a money market graph from memory.

Answer - if the fed is buying bonds,, then it is paying for those bonds in cash,,, citizens are giving up their bonds and receiving cash. The money supply is therefore increasing. As the money supply increases nominal rates are falling.  Look Below.


(c) Assume the Federal reserve buys government bonds from commercial banks. Based only on this transaction, will the level of required reserves in the commercial banks increase, decrease, or remain the same?


You should understand that the required reserves are required for customers demand deposits (checkable accounts),, cash from selling assets does not effect the banks reserve requirements. 


Answer - Fed's purchase of bonds will not initially affect commercial banks required reserves.

(d) another monetary policy action involves changing the discount rate. Define the discount rate.

Answer - the discount rate is the interest rate that the Fed charges banks for borrowing from it's discount window.

How I would have looked at the college board 
after Reading some of these questions.
