- 15. Suppose that the relationship between inflation rate (π) and unemployment rate (u) is described by the following equation: πt – πte = (m + z) – αut where m = 0.05, z = 0.04, and α = 2. In this economy, the authorities keep unemployment rate at 4% forever. a. If the modified Philips curve describes the relationship between π and u correctly, how should “πte” be specified? Rewrite the equation using this specification. Assume that πt–1 = 1%. Compute πt, πt+1, and πt+2. b. Do you believe the answer in part (a)? Why or why not? c. Derive the natural rate of unemployment.Please no written by hand solutions Suppose that the markup of goods prices over marginal cost is 5%, and that the wage-setting equation is W= P(1-u), where u is the unemployment rate. a. What is the real wage, as determined by the price-setting equation? b. What is the natural rate of unemployment? c. Suppose that the markup of prices over costs increases to 10%. What happens to the natural rate of unemployment? Explain the intuition behind your answer.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.
- Based on Okun's rule of thumb, if you forecast that the output gap will decline from -1% to -3%, the unemployment rate will: O rise by 0.5%. rise by 2%. O rise by 1%. fall by 1%.Suppose the working-age population is 50 million, the labour force is 20... Suppose the working-age population is 50 million, the labour force is 20 million, and the unemployment rate is 15 per cent. The number of unemployed people is a. 4.5 million. O b. 7.5 million. O C. 10.5 million. O d. 1.5 million. O e. 3 million.Consider the expectations adjusted Phillips’s curve and assume that expected inflation is given by πet = πt-1. Suppose that unemployment is initially equal to the natural rate and that π=10%. The central bank decides that inflation is too high and that, starting in year t, it will maintain the unemployment rate 1% point above the natural rate until the inflation rate has decreased to 2%. (a) What is the sacrifice ratio in this economy [Hint: the sacrifice ratio is the percentage of a year’s excess unemployment needed to reduce inflation by 1%. For a Philips curve given as πet − πt −1 = −α (ut − un ), the sacrifice ratio is 1/α]? (b) Compute the rate of inflation for year t, t+1, t+2, t+3, …, t+8. (c) For how many years must the central bank keep the unemployment rate above the natural rate of unemployment? Is the implied sacrifice ratio consistent with your answer to (a)?
- Unemployment rates have been higher in many European countries in recent decades than in the United States. Is the main reason for this long-term difference in unemployment rates more likely to be cyclical unemployment or the natural rate of unemployment? Explain briefly.3. a. Provide a definition for the natural rate of unemployment. How is your definition related to the potential output? b. What are different unemployment categories that are included in the natural level of unemployment? Provide at least one example for each categoryFigure: Aggregate Demand) Point B on this aggregate demand curve represents an inflation rate of: O A. 3% O B. 4% O C. 5%. O D. 7%
- Suppose that in an economy with production equal to the natural level, Y=A*N, Yn-5000, L=6250 and A=1. We know that the natural rate of unemployment of this economy is: 1. 0.15 2. 0.25 3. 0.2 4. 0.1.The Philips curve in an economy is given by a = Επ- 0.5 (u - 6). Assume that the economy starts out at its natural unemployment rate and expected inflation Ex = 5.25%. If output decreases by 2%, using Okun's Law and the Phillips curve relation, what is actual inflation π ?Why does this mean? "the natural rate of unemployment" and also can elaborate more on why the longrun philips curve is vertical at the rate? why inflation is also constant in longrun equillibrium?
