the natural unemployment rate is 7 percent and the expected inflation rate in 2017 is 3 percent a year. If the inflation rate is expected to rise to 5 percent a year in 2018, explain how the short-run and the long-run Phillips curves will change.

1. Aggregate demand, aggregate supply, and the Phillips curve In the year 2027, aggregate demand and aggregate supply in the imaginary country of Aso-Kuju are represented by the curves AD2027 and AS on the following graph. The price level is currently 102. The graph also shows two potential outcomes for 2028. The first possible aggregate demand curve is given by the curve labeled ADA curve, resulting in the outcome given by point A. The second possible aggregate demand curve is given by the curve labeled ADB, resulting in the outcome given by point B. PRICE LEVEL 108 107 106 105 104 103 102 101 100 0 AD 2027 2 4 B AS ADB ADA 8 10 6 OUTPUT (Trillions of dollars) 12 14 16 (?) Suppose the unemployment rate is 7% under one of these two outcomes and 5% under the other. Based on the previous graph, you would expect outcome B▼ to be associated with the lower unemployment rate (5%). If aggregate demand is high in 2028, and the economy is at outcome B, the inflation rate between 2027 and 2028…

The Short-Run Phillips Curve given by T = E (x) – 0.4 (u – 10) + v Suppose that the economy has adaptive expectations and no inflation shocks. If inflation goes down by 3.3 percentage points a year from today, what is the unemployment rate one year from now? Round your answer to the nearest two decimal place. Write your answer in percentage terms so if your answer is 10%, write 10.
