3. Discuss the relationship between the natural rate of unemployment, Un, and the Phillips curve, 1lt...
3. Suppose that the Phillips curve is given by: It = TE + a - but, where is the inflation rate, Ti is the expected inflation, ut is the rate of unemployment and, a and b are two positive parameters. Suppose that a fraction 1 € (0,1) of wage contracts are indexed to inflation and Ti = litt + (1 - 1) Tt-1. (a) Derive the new equation for the Phillips curve. [2 marks] (b) Derive an algebraic expression for...
4)- Suppose for a given economy, the Phillips Curve is given by itthen 0.25 ut + 1.25%, and the Okun's law: ut - Ut-1=-0.5gyt + 4%. Also assume that Teen Tt-1, and the growth rate of money supply has been 18% for a long time. (Total 19 points) a)- What are the inflation rate, unemployment rate, and growth rate of output at the medium run equilibrium. (4.5) b)- Calculate the natural rate of unemployment and NAIRU. (2) c)- Starting from...
Suppose the Phillips Curve is an accurate depiction of the inflation/unemployment trade off. Assume there are no exogenous supply shocks and agents set price expectations adaptively. Let NAIRU be positive. What happens to the Phillips curve if the inflation responsiveness to unemployment decreases? A. The Phillips curve becomes flatter and does not shift. B. The Phillips curve becomes steeper and shifts up. C. The Phillips becomes flatter and shifts down. D. The Phillips curve becomes steeper and does not shift.
So let's say that this European Central Bank, the European Central Bank expects the natural unemployment rate to be 6 percent, and the actual unemployment rate is 5.5 percent.A.) Use the Phillips curve illustration to determine what happens to inflation and unemployment over a long period of time.B.) Assuming the expectation is the actual natural unemployment rate (5.5%), then if the government decides to increase government spending, please briefly explain and use the Phillips curve to illustrate.
Problem 3.(36 points) Suppose the natural rate of unemployment equals 5%, and the Phillips curve is given by πt = πte − 0.25(ut − u∗t ). Suppose originally the economy is in the long run equilibrium, in which πte = 4%. 1. Determine unemployment and inflation rates corresponding to the original equilibrium. 2. Draw the Philips curve diagram with SRPC and LRPC. Mark the original long run equilibrium. 3. Suppose now the central bank performs a monetary expansion and raises...
In the long run, the Phillips Curve shows that a. the natural rate of unemployment is independent of fiscal and monetary policy changes. b. unemployment and inflation have a direct relationship. c. an increase in unemployment leads to an increase in inflation. d. there is an inverse relationship between inflation and unemployment. e. unemployment increases when inflation decreases.
8. The Phillips curve is based on the observed negative relation between the rate of inflation and the unemployment rate. That is, decreases in the unemployment rate tend to be associated with increases in the rate of inflation a) Given what you know about the relation between the unemployment rate and the GDP gap, restate the Phillips curve in terms of inflation and the GDP gap. b) Based on the AD-IE model, and given your answer in (a), explain why...
Suppose that the Phillips curve is given by 𝛑 = 𝛑⁴ - 2(u-5) What is the natural rate of unemployment?
The Phillips curve exhibits Short-run Phillips curve Inflation rate (%per year) A. the direct relationship between the unemployment and the inflation rates 0 B. the situation where cyclical unemployment becomes zero. O C. the inverse relationship between the actual and the natural rate of unemployment. D. the relationship between the unemployment and the inflation rates Use the line drawing tool to draw a short-run Phillips curve. Properly label this line Note: if you are not prompted for a label, you...
a. Given the original Phillips curve, why is there a negative relation between inflation and the unemployment rate? State the two reasons why the original Phillips curve vanished. b. Define the natural rate of unemployment and list down its determinants. What happens to inflation when unemployment is greater than the natural rate of unemployment? When unemployment is lower than the natural rate of unemployment?
