Suppose that an economy has the Phillips curve: n = n(-1)-0.5 (u - 0.05) a. What is the natural rate of unemployment? How much cyclical unemployment is necessary to reduce inflation by 3 percentage points? Using Okun's law, compute the sacrifice ratio. b. Inflation is running at 6 percent. The central bank wants to reduce it to 2 percent. Give two scenarios that will achieve that goal.

(f) Discuss the differences, and similarities if any, between the Phillips Curve and Okun's Law.
Suppose that the public expects that inflation will be high and that episodes of high unemployment are politically difficult for policymakers. Is it possible for the economy to be at a bad equilibrium as a result of people’s expectations of inflation (i.e. expectations trap)? Explain in terms of a Phillips Curve diagram.
True or false? According to the Phillips curve, in the long run there is a trade-off between inflation and unemployment
If the current inflation rate is 10% and you are asked to predict the cost of decreasing it to 3% next year. 1)Will it result deflation policy or a disinflation policy? Why? 2) Give an estimate of the cost in terms of output assuming the sacrifice ratio is 4 and explain the economic cost of reducing inflation by drawing the Phillips curve. 3) If an economist says computing the cost of this policy using the sacrifice ratio is not totally correct because people are rational and they will take the new policy into account when forming expectations about the future. Explain this statement and the reason behind it by showing what happens the Phillips curve 4)if people update their expectations about the future instantaneously. How costly would it be to reduce inflation if the adjustment in expectations occurs instantaneously?
The Phillips curve in Lowland takes the form of π = 0.04 – 0.5 (u – 0.05), where π is the actual inflation rate and u is the unemployment rate. The Phillips curve in Highland takes the form of π = 0.08 – 0.5 (u – 0.05). The current unemployment rate in both countries is 9 percent (0.09). Explain the similarities in the Phillips curves in Highland and in Lowland.
The Phillips curve is the relationship between (a) Change in GDP from potential and inflation. (b) GDP and unemployment. (c) The percent change in GDP and inflation. (d) The percent change in GDP and unemployment.
a) Explain the concept of the natural rate of unemployment using the expectations-augmented (modified or modern) Phillips curve model. b) Why is this model useful for policy-makers?
Can you answer this for me?

As with demand and supply analysis, changes in the economy can cause both shifts of and movements along the short-run Phillips curve. Which of the following would cause a shift of the short-run Phillips curve? Check all that apply. An increase in government spending A decrease in short-run aggregate supply An increase in the expected inflation rate
Suppose that the Phillips curve is given by +0.1-2 U₂ and expected inflation is given by -(1-0) * +04-1 where 0 is equal to zero and x 0.02 and does not change. The economy is initially at the natural rate of unemployment, which is 5%, when the authorities decide to bring the unemployment rate down to 3% and hold it there forever. With 0 equal to zero, this will yield a 6% rate of inflation every year. Now suppose that in year (t+6), 0 changes to 1. 0 might increase in this way because OA government policy would mandate inflationary expectations. B. inflation expectations adapt to persistently positive inflation OC. inflation expectations change constantly. OD. inflation expectations always adapt immediately to the last period's inflation. In year (+6), the inflation rate will be % (Enter your response as an integer.) In year (+7), the inflation rate will be % (Enter your response as an integer.) In year (+8), the inflation rate will be%. (Enter your response as an integer)
