Question

Suppose an economy has a money growth rate of 5%, a velocity growth rate of 2%, and a Solow growth rate of 4%. What is the inflation rate in this economy in a long run equilibrium?

3%

5%

10%

2%

Answer #1

Option A.

- In order to calculate the inflation rate in this economy in a long run equilibrium, we can use the equation of quantity theory of money.
- This equation shows the relationship between the price's and the money supply that prevail in the Economy at the current inflation rate.
- The equation is given by : QTM = M + V = P + Y

Where, M = Money growth(5%) , V = velocity of money(2%), P = interest rate/ price level(?), Y = real GDP( 4%)

By substituting these in the equation we get,

QTM = M+V = P+Y

5 + 2 = P + 4

P + 4 = 7

P = 7 - 4 = 3%

Therefore, the inflation rate in this economy is 3%.

Consider an economy has had growth in real GDP of 3.1% and
growth in the money supply of 4.9%.
a) If velocity has been constant for this economy, what will be
the rate of inflation?
b) If instead the velocity had increased by 5.6%, what will be
the rate of inflation?
c) The quantity theory of money theorizes that the rate of
inflation is determined by the growth of the money supply. What is
the key assumption for the quantity...

Suppose the growth rate of the money supply is 3 percent, the
growth rate of velocity is 4 percent, and the growth rate of real
aggregate output is 2 percent. According to the equation of
exchange, the inflation rate would be _____ percent
Select one:
a. 7
b. 6
c. 5
d. 4
e. 3

Suppose the annual growth rate of real GDP for some fictional
economy is 6%, the growth rate of velocity is 0%, and the growth
rate of the money supply is 11%.
Using the quantity theory of money, what is the current rate of
inflation?
Using the quantity theory of money, what will happen to the
inflation rate if the growth of the money supply increases to
15%?
Using the quantity theory of money, what will happen to the
inflation rate...

If the growth rate of the money supply is 8%, velocity is
constant, and real GDP grows at 4% per year on average, then the
inflation rate will be _____%.
If the growth rate of the money supply increases to 13%,
velocity is constant, and real GDP grows at 2% per year on average,
then the inflation rate will be _____%.
If the growth rate of the money supply increases to 13%,
velocity grows at 11%, and real GDP grows...

5. Assume that the economy has been growing at 2 % per
year. You are an economist working at a Central Bank and need to
establish what are the long-run effects of increasing the growth of
the money supply to 10 % per year. State and then explain the
long-run effects of this change on each of the following (give
numerical estimates when possible):
a) The annual rate of inflation
b) The real interest rate
c) The nominal interest rate

Suppose that an economy has the Phillips Curve
If the economy has the Non-Accelerating Inflation Rate of
Unemployment as 5%, demonstrate in the Phillips Curve figure the
short-run and long-run values on inflation and unemployment. Make
sure to include specific numerical values.

2. Suppose that in the U.S., the income velocity of money (V) is
constant. Suppose, too, that every year, real GDP grows by 2.5
percent (%∆Y/year = 0.025) and the supply of money grows by 10
percent (%∆M/year = 0.10).
a. According to the Quantity Theory of Money, what would be the
growth rate of nominal GDP = P×Y? Hint: %∆(X×Y) = %∆X + %∆Y.
b. In that case, what would be the inflation rate (i.e.
%∆P/year)?
c. If the...

Compared with a closed economy, an increase in the growth rate
of the money supply in an open economy increases aggregate demand
by a:
A.
larger amount only in the short run.
B.
smaller amount in both the short run and the long run.
C.
smaller amount only in the short run.
D.
larger amount in both the short run and the long run.

explain clearly the rationale behind your numerical answers.
a. suppose the multiplier is 1.5, the income multiplier with
respect to the money supply is 2, the money multiplier is 4.5, and
a central bank purchase of $6b of bonds during a recession drops
the interest rate by one percentage point. suppose that to fight a
recession, monetary policy is undertaken to lower the interest rate
by two-thirds of a percentage point. what should happen to the
income level?
b.suppose the...

Suppose that the money demand function takes the following
form:
[ ? ? ] ? = ?(?, ?) = ? /5?
a. What is the velocity of money in this economy? Show your
work.
b. If expected inflation and nominal interest rates are
constant, at what rate, if any, will velocity grow? Explain your
answer.
c. How will a permanent (once-and-for-all) increase in the level
of the nominal interest rate affect the level of velocity? How will
it affect the...
