2019 AP Macro FRQ #1

2019 AP Macro FRQ #1






Understand that "no policy action" implies a classical view.

(b)(i) If no policy actions are taken then workers will accept lower wages, lower wages will shift the SRAS curve rightward, as wages fall business owners will lower the prices of goods and services, lower prices means people buy more stuff and output increases back to the full employment level.

The classical view implies that the economy has flexible prices and wages
and therefore will always return back to LR equilibrium just at a lower price level.
(b)(ii)



If the MPC is .8 then the MPS is .2 as they together always equal 1.
To find the government spending multiplier we can use the formula 
1/MPS or 1/1-MPC

I'm like a child and always use the simplest of 1/MPS or 1/.2 = 5
Our spending Multiplier is 5

This implies that anything spent by the Government will be multiplied by 5

If we are in a recession at $500b and full employment is $540b
then we need $40b of GDP increase to close the recessionary gap.

40b/5 = 8b

If the government spends 8b and we multiply that by the GS Multiplier (5)
we get an increase in GDP of 40b.

(c)(i) Minimum change in spending increase of 8b.


Understand that the short understanding is to recognize that the 
Government Taxing Multiplier is always 1 less 
than the Government Spending Multiplier
(Explanation here)

So, our taxing multiplier is going to be 4
The government would have to reduce taxes by 
40b/4 = 10b
to get the aggregate demand curve to full employment.
Reducing taxes is expansionary and we are in a recession so reduce taxes.



(c)(ii) Minimum change by decreasing taxes of 10b.




As the Canadian Central Bank (FED) buys bonds the MS will increase, driving down the
Nominal Interest Rates, lower interest rates stimulate investment, increasing aggregate demand
getting us back to full employment.

Recognize that lower interest rates inside the country 
attracts investors that want to take out loans from banks.
Charge an interest rate




Understand that capital flows of currency from one country to another
are about putting money into banks to get a higher return.

As the rate of interest in Canada falls, Canadian citizens look to put
their money into Mexican banks that pay a relatively higher interest rate.
Pay an interest rate.

Canadians will dump their monies into the FOREX increasing the supply of
Canadian dollars in the FOREX, therefore the value of the Canadian dollar decreases
 relatively to the Mexican Peso
