Question

In the country of Wiknam, the velocity of money is constant. Real GDP grows by 5 percent per year, the money stock grows by 14 percent per year, the nominal interest rate is 11 percent and the real interest rate is 2%

1. In Wiknam if Real GDP growth slows what would you expect to happen to the inflation rate? Explain using the model why.

2. If Wiknam households expect higher inflation in the coming year, how might that effect Money Demand? How would that affect the real interest rate, the nominal interest rate and actual inflation? (hint: use the chart that links money, prices and interests rates)

Answer #1

At the given rates, growth rate of velocity is 0 and growth rate of prices or inflation rate = growth rate of money - growth rate of real GDP = 14% - 5% = 9%. Also nominal interest rate is 11% and real interest rate is 2% which again gives inflation rate of 9%.

a) If real GDP growth rate is reduced, and money supply growth rate is same, then inflation rate should rise. This is because the two are inversely related under the quantity theory:

inflation rate = growth rate of money - growth rate of real GDP

Lower growth rate of real GDP with unchanged growth rate of money implies higher inflation rate

b) Higher expected inflation will result in increasing the money demand because purchases will be preponed. This will increase the nominal interest rate as well as the actual inflation when aggregate demand is increased. Real interest rate would remain unchanged.

(1) In a country A, the velocity of money is constant. Real GDP
grows by 4 percent per year, the money supply grows by 8 percent
per year, and the nominal interest rate is 9 percent. What is:
(a) the growth rate of nominal GDP?
(b) the inflation rate
c. real interest 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...

The velocity of circulation grows at 1 percent and real GDP
grows at 3 percent. If the quantity of money grows at 2 percent,
the inflation rate is
Select one:
a. zero.
b. 8 percent.
c. 10 percent.
d. 4 percent.
e. 2 percent.

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...

Suppose that this year’s money supply is $400 billion, nominal
GDP is $10trillion, and real GDP is $4 trillion.
1.What is the price level? What is the velocity of money?
2. Suppose that velocity is constant and the economy’s output of
goods and services rises by4% each year. What will happen to
nominal GDP and the price level next year if the Fed keeps the
money supply constant?
3.What money supply should he Fed set next year if it wants...

The velocity of money in the small Republic of Sloagia
is always the same. Last year, the money supply was $ 7 billion and
real GDP was $ 20 billion.
This year, the money supply increased by 5 percent, real
GDP by 4.2 percent, and nominal GDP is $ 19 billion.
Calculate the velocity of money
The price level last year,
The Price level this year
The inflation rate.

1 (a) An economy’s money supply growth is 6 per cent, real
output growth is 4 per cent, and nominal interest rate is 3 per
cent.
Find the inflation rate.
Find the real interest rate.
(b) How would falls of GDP growth due to Covid-19 pandemic
affect inflation rate in the
economy?
