- 2. What is the eqution and shape of the modem aggregate supply curve according to imperfect infomation model? Using the equation of Aggregate Supply (AS) derive the equation of Expectation augmented Phillips curve and explain causes of inflation in tems of it. How does expectation augmented Phillips curve explain Stagflation?While hyperinflations are always caused by rapid growth in the money supply, they can be intensified by the actions of households and firms trying to protect themselves from inflation by spending money as soon as they receive it. During a hyperinflation, the velocity of money is likely to Use the quantity equation to show how the change in vel Holding the growth rate of real GDP constant, this chang increase remain unchanged decrease ▼inflation image 1Two main macroeconomic concerns are the problems of inflation andunemployment.a.

With reference specifically to ONEof these causes, suggest ONE practical government policy that reducesthe natural rate of unemployment.
