- It is sometimes suggested that the Fed should try toachieve zero inflation. If we assume that velocity isconstant, does this zero-inflation goal require that therate of money growth equal zero? If yes, explain why.If no, explain what the rate of money growth shouldequalSuppose that an economy has a constant nominal money supply, a constant level of real output Y = 1500, and a constant real interest rate r = 0.05, and it’s expected rate of inflation is 2%, i.e, πe = .02. Suppose that the income elasticity of money demand is ηY = 0.5 and the interest elasticity of demand ηi = –0.2. (a) Suppose that Y decreases to 1425, r remains constant at 0.05 and there is no change in the expected rate of inflation. What is the percentage change in the equilibrium price level? (b) Suppose that r increases to 0.06 and Y remains at 1500. Assuming that expected inflation remains at πe = .02, what is the percentage change in the equilibrium price level? (c) Suppose that r increases to 0.06. Assuming that πe = .02, what would real output have to be for the equilibrium price level to remain at its initial value?Suppose the money demand function is = 1000 + 0.2Y - 1000 (r + πe). Required (a.) Calculate velocity if Y = 2000, r = 0.06, and πe = 0.04. (b.) If the money supply (Ms) is 2600, what is the price level? (c.) Now suppose the real interest rate rises to 0.11, but Y and Ms are unchanged. What happens to velocity and the price level? (d.) For part (c.), if the nominal interest rate were to rise from 0.10 to 0.15 over the course of a year, with Y remaining at 2000, what would the inflation rate be?
- Suppose that this year’s money supply is $500 billion,nominal GDP is $10 trillion, and real GDP is $5 trillion.a. What is the price level? What is the velocity ofmoney?b. Suppose that velocity is constant and theeconomy’s output of goods and services rises by5 percent each year. What will happen to nominalGDP and the price level next year if the Fed keepsthe money supply constant?c. What money supply should the Fed set next yearif it wants to keep the price level stable?d. What money supply should the Fed set next yearif it wants inflation of 10 percent?Assume that next year’s wage rate will be 3 percent higher than this year’s because of inflationary expectations. The actual inflation rate is 4 percent. At the beginning of next year, will the real wage be higher, lower, or the same as today? Explain. Assume that Mark gets a fixed-rate loan from a bank when the expected inflation rate is 3 percent. If the actual inflation rate turns out to be 4 percent, who benefits from the unexpected inflation: Mark, the bank, neither, or both? Explain.

- Social loss is L=(u-5)^2+(pi-2)^2Philips curve is u=7-(pi-pi_e), where pi is actual inflation rate, pi_e is expected inflation by the public. (1)If gov't is honest, then gov't should choose pi =____ (2)If gov't is sophisticated and public is naive, then gov't should announce pi_a =____ (3)If gov't is sophisticated and public is naive, then gov't should choose pi =____2.1 Money demand in an economy in which no interest is paid on money is Md/P =1000 + 0.4Y- 100i (a) Given that P = 100, Y = 1000, and i = 0.10. Find real money demand, nominal money demand, and velocity.(6)(b)The price level doubles from P =100 to P = 200. Find real money demand, nominal money demand, and velocity.( c) Starting from the variables given in part (a) and assuming that the money demand function as written holds, determine how velocity is affected by an increase in real income, (ii) an increase in the nominal interest rate, (iii) an increase in the price level.24. Which of the following groups benefit from an unanticipated rise in the inflation rate ? O. homeowners with foxed - rate mortgages O. elderly people living on fixed incomes O. creditors or lenders O. workers on contracts without escalator claines 25. Suppose oil prices continue to rise , causing a supply shock . If the Fed increases interest rates , what would be the long run outcome ? O. The economy returns to long run equilibrium at a lower output but higher price level O. The economy returns to long run equilibrium at the original price level and output O. The economy returns to full employment but at a higher price level O. The economy returns to the original price level but at a lower output
- QUESTION 5Which of the following best describes inflation?O a. Economic growth.O b. An increase only in the price of energy.O c. An increase in the overall price level in an economy.O d. Ballooning debt.4. Justin's demand for good 1 is given by the formula: x1d(p1,p2,I)=2⋅I/4⋅p1+6⋅p2, Suppose... p1=$7/unit p2=$7/unit and I=$266 By how much will Justin's consumption of good 1 change if all prices AND his income were to double? (When all prices and income increase by the same percent, as is the case here, this is called "pure inflation").
