ALL GDP FRQ's

ALL GDP FRQ's


2011B AP Macroeconomics Exam

(A.) 2009 is the base year calculate the following
(i) NGDP in 2010

NGDP = P x Q
so, 8 x 2.5 = $20
10 x 10 = $100
5 x 5 = $25
Total 2010 NGDP = $145
(ii) The Real GDP in 2010
We find the RGDP 
by using the quantity produced in the current year x prices of the base year
2.5 x 8 = $20
6 x 10 = $60
4 x 5 = $20
RGDP 2010 = $100

(B.) If one years price index is 50 and in the next year the index is 55, what is the rate of inflation from one year to the next?

Rate of Change Formula ((New - Old)/Old) x 100
55-50 = 5
5/50 = .1 x 100 = 10
rate of inflation = 10%

I also like the method in this scenario of doubling both numbers
50 x 2 = 100
55 x 2 = 110
rate of inflation from one year to the next = 10%

this works well if you can divide by 2 also
if the price index = 200 one year and 250 the next
200/2 = 100
250/2 = 125
Rate of inflation from 100 to 125 = 25% inflation

(C.) Next years wages will be 3% higher, but the actual inflation rate is 4%. At the beginning of next year will the real wage be higher or lower or the same as today?

If we get a raise and Nominal Wages increase by 30% we are very happy
but ,, if the PL (Inflation) rises by 4%, all things are 4%more expensive
then we are worse off even with our wage increase
Our Real wages fell by 1%


(D.) Sara gets a fixed rate loan from a bank when the expected inflation rate is 3%.
If actual inflation is 4%who benefits from the unexpected inflation, Sara, the Bank or neither?

If Sara got a loan at 3% and actual inflation is more than expected then Sara benefits
for now she is paying back money that has a lower purchasing power





2008B AP Macroeconomics Exam

(A.) Calculate the NGDP.
NGDP = P x Q
400 x $6 = $2,400
1,000 x $2 = $2,000
800 x $2 = $1,600
NGDP = $6,000


(B.) GDP Deflator is 100 in the base year,, and 150 this year. Calculate each of the following.

(i) The inflation rate, expressed as a percentage, between the base year and this year.


Rate of Change Question
100 to 150 = 50% increase

(ii) This years RGDP
If given the NGDP and the Index (CPI or Deflator)
NGDP/Index = RGDP
6,000/1.5 = $4,000


(C.) The workers received a 20% increase in nominal wages, but workers face the inflation you calculated in B(ii), what happened to their real wages?

Nominal - Inflation = Real
Nom Wages increase by 20% (Yippe) but inflation (the price of everything) went up by 50%
your real wages fell by 30%
Your real wages = the actual goods you can buy after the inflation increase


(D.) If the GDP deflator increases unexpectantly, would a borrower be better off , worse off, Explain.

If you borrow and inflation increases, you are paying back the loan with money that can buy less stuff
Ha, ha, take that lender.
The borrower benefits.
