Homework 4. Q4
(a)Suppose that the velocity of circulation of money is
constant, but GDP is not and assume that GDP grows by
5% per year, the quantity of money grows by
14% a year and the nominal interest rate is
11%, can you calculate the real interest
rate?(Hint: you should use the equation ∆M +∆V = ∆P +∆Y and
the Fisher equation.)
(b)Do you believe that people can have expectations that are
consistently wrong in the long-run? In other words, do you believe
that expectations are right on average? Why or why not?
(c)As mentioned above, V is fairly constant in the long run in the
States and other “stable” countries. But there are times/places in
which V is not constant, can you explain in which case the velocity
of circulation of money will not be constant? Explain
carefully your answer!
Ans
1 real interest rate=nominal rate-real Gdp growth rate=14-5=9%
2 Yes they can be wrong. This is because economic phenomenon is not always same. It changes frequently and it is quite difficult for ordinary people to understand full implications
3 Due to technological improvements in monetary system Velocity can change. Similarly war etc can change it

Suppose that the velocity of circulation of money is constant and real GDP is growing at 2 percent a year. a) To achieve an inflation target of 2 percent a year, at what rate would the central bank (Bank of Canada) grow the quantity of money? b) At what growth rate of the quantity of money would deflation be created?
The velocity of circulation is constant, real GDP is growing at 5 percent a year, the real interest rate is 2 percent a year, and the nominal interest rate is 3 percent a Calculate the inflation rate, the growth rate of money, and the growth rate of nominal GDP The inflation rate is percent a year The growth rate of money is percent a year. The growth rate of nominal GDP percent a year Google Sei
5. Suppose in the United States economy, the rate of money growth for the current year is 8 percent, the velocity of money in circulation is constant, and inflation is expected to be about 2 percent over the current year. What is the short run economic growth rate? A) 16 percent B) 10 percent C) 8 percent D) 6 percent E) 4 percent 8. The fisher effect matters in terms of inflation given that A) borrowers agree to loan terms...
Question 5 of 5 3 Points Assume the velocity of money is constant. Real GDP grows by 3 percent per year, the money stock grows by 5 percent per year, and the nominal interest rate is 5 percent. What is the real interest rate? Show all formulas used and steps taken.
• if the velocity of money is 2, the money supply in this economy is ($4.5 trillion/ $18 trillion/ $27 trillion/ $36 trillion/ $45trillion /$54 trillion) •because ( the federal reserve controls M/ velocity is assumed to be constant/ the AD curve is downward sloping ), the percentage increase in the price level Is ( less then/ the same as/ greater then ) the percentage increase im the money supply. the illustrates the ( importance of the federal reserve /...
Question 6: Inflation and the quantity theory Suppose velocity is constant, the growth rate of real GDP is 3% per year, and the growth rate of money is 5% per year. Calculate the long-run rate of inflation according to the quantity theory in each of the following cases: (a) What is the rate of inflation in this baseline case? (b) Suppose the growth rate of money rises to 10% per year. (C) Suppose the growth rate of money rises to...
4) Suppose in the economy in the next couple years, bitcoin and other alternatives to money become even more popular. As a result, money demand (demand for $) goes down. a) Draw IS/LM and AD/AS diagrams, label the initial long-run equilibrium. Now show the effect of the decrease in money demand on both diagrams and label the short-run equilibrium. b) If policymakers do nothing, what will happen in the long-run after this decrease in money demand? c) Suppose instead that...
Which statement best defines the velocity of money? (1 mark) a. It is the rate at which the central bank puts money into the economy. b. It is the long-term growth rate of the money supply. c. It is the money supply divided by nominal GDP. d. It is the average number of times per year a dollar is spent. In the 1970s, in response to recessions caused by an increase in the price of oil, the central banks in...
