The following graph plots the short-run and long-run Phillips curves (SRPC and LRPC, respectively) for an economy currently experiencing long-run macroeconomic equilibrium at point A, where the natural unemployment rate is 6% and the inflation rate is 8% per year. Suppose that the central bank for this economy has decided that inflation is too high and thus wants to decrease the inflation rate by 6 percentage points per year. A reduction in the rate of inflation is known as   (deflation/disinflation) . To reduce inflation from 8% to 2% in the short run, the central bank would have to accept an unemployment rate of____% True or False: If people have rational expectations, the economy may not have to endure an unemployment rate as high as predicted by the short-run Phillips curve. -True   -False

Suppose the current inflation rate is a constant 7% and the central bank implements a disinflation policy to reduce it to its target rate of 3%. To achieve this objective the central bank, by increasing its cash rate, raise the nominal interest rate from its current 9% to 14%. In the long run, at which the central bank achieves its inflation target, what will be the nominal rate of interest, the real rate of interest and the inflation rate?

Use the data in the following table to calculate the refinancing rate (i) using the Taylor rule, and fill in the last cell in table. Variable Value Equilibrium real refinancing rate (r*) 2% Four-quarter average inflation (1) Inflation target („T) 2% 1% Output (Y) 11.5 Potential output (Y*) 12 Weight on the output gap (w1) 0.5 Weight on the inflation gap (w2) 0.5 Refinancing rate (i) Suppose that the equilibrium real refinancing rate (r*) is 1% instead of 2%. Based on the Taylor rule and assuming everything else remains the same, how would this change the refinancing rate (i) you calculated in the previous question? The central bank should set the refinancing rate at 1.42%. The central bank should set the refinancing rate at -0.58%. For every percentage point lower the equilibrium real refinancing rate goes, the nominal refinancing rate should be 1 percentage point higher. Suppose the inflation rate over the last four quarters has been 3% instead of 2%. Assuming everything else is the…

Aggregate demand function is given by Y=7000-20P; the shirt-run aggregate supply function is given by Y=6000+5(P-Pe). The economy was in equilibrium when the government unexpectedly increased its spending which led to a shift of the aggregate demand curve to Y=7500-20P. What's the rate of inflation? Please illustrate the calculations by means of an AS-AD graph.
