- 1 Inflation in the period t in the economy is described by the following function Tt -0.3 + 0.06u, + T where T; - inflation in the period t, ut - unemployment in the period t. Inflation expectations are formed adaptively: T = 0.7Tt-1 + 0.37_1, where T is the expected inflation in the period t. Let's assume that initially, in the time period t is equal to TO reduction of the inflation rate to the level of 0.05, starting from the year t: unemployment rate in year t = 0 and in year t = 1. 0, the inflation rate coincides with the level of inflationary expectations and T = 0.1. The Central Bank is conducting a policy of permanent (once and for all) 1. Calculate theProblem 5. Suppose people's inflation expectations are subject to ran- dom shocks: at time t-1, expected inflation in time t is Et-1t = Tt-1+t-1 where nt-1 is a random shock with mean zero but deviates from zero when some event beyond past inflation causes expected inflation to change. Also, Ett+1 = πt +Nt. 3 A. Derive the DAD and DAS equations. Hint: For DAS, express T as a function of (Y - Y); for DAD, express Y, as a function of (T- πt). B. Suppose the economy experiences an inflation scare: in period t, people believe that inflation in t+1 will be higher so nt> 0 (but for this period only). What happens to DAD and DAS in t? Explain what happens to output, inflation, nominal interest rate, and real interest rate. Show a graph and provide labels for equilibrium points (A, B, C, etc.) as needed.In a decelerating inflation environment (e.g. with inflation rate at 20%, 18%, 14%, .. year after year), using "adaptive inflation expectations" formation, the forecasted future inflation rate is likely to be O systematically biased upward. O systematically biased downward. O always correct. O about correct on average.

How does expectation augmented Phillips curve explain Stagflation?My question is (c). Basically, AS curve becoming steeper can be reflected by the value of v bar increases, showing that inflation is more sensitive to SR AD shock. However, this is no impact on AS shock theoretically, as AS shock relates to the change of o bar. So I guess maybe the provided solution is wrong, could u please check it for me? Thanks a lot!

Assuming people form expectations adaptively, which of the following statements are correct? Choose one or more: OA Monetary policy can reduce unemployment only if the policy is expected. OB. When inflation is increasing from year to year, people tend to overestimate inflation. OC. When inflation is decreasing from year to year, people tend to overestimate inflation. O D. When inflation is decreasing from year to year, people tend to underestimate inflation. OE When inflation is increasing from year to year, people tend to underestimate inflation.The text proposes the following model of expected inflation x = (1 - 0) x + 0,-1 What do we know about your process of the formation of expected inflation when 0 = 07 OA.

Suppose inflation is described by the accelerations Phillips curve, and that output is determined by a simple IS curveInitially, the central bank is setting the nominal interest rate at a strictly positive level: i(0) > 0. Assume(a) Suppose the central bank keeps i constant at i (0). Sketch the behavior of inflation and output over time.(b) Suppose the central bank keeps i constant at i (0) until some time when bπ(t) < 0, and then permanently reduces i to zero.
