1. Imagine an economy, where the SRAS in terms of inflation is given by II=5+Y, where Y is output. Imagine that the long run AS curve is given by Y=2. (25 marks) a) Give the equation of the AD curve (you can take liberties), if we assume that initially, the economy is at its long-run equilibrium. Justify. b) Imagine that your chosen AD curve's intercept goes up by one unit due to an expansionary monetary policy. What will be the new final equilibrium after this change? Justify. c) What will be the equilibrium after two periods of adjustment? Justify. d) Assume that before all the changes in the economy, in the initial, long-run equilibrium, the interest rate was 4 percent. Give an IS and an LM curve that are compatible with this initial equilibrium. Justify. e) What are the IS and LM curves going to be at the very end of the adjustment process, i.e., in the new long run equilibrium? Justify.

Consider the figure to the right. If this country's government decides to increase its short-term spending, what happens to the short-run equilibrium price level, and why? Is this an example of demand-pull or cost-push inflation? Explain. 1.) Using the line drawing tool, draw either a new aggregate demand (AD) curve or a new short-run aggregate supply (AS) curve that shows the effects of temporary government spending increases. Properly label your line. 2.) Using the point drawing tool, indicate the economy's new short-run equilibrium price and level of real GDP. Label this point 'E₂.' Carefully follow the instructions above, and only draw the required objects. Price Level LRAS₁ Real GDP per Year (S trillions) AS₁ AD₁

In the dynamic model of AD-AS in the diagram to the right, the economy is at point A in year 1 and is expected to go to point B in year 2, and the Federal Reserve pursues policy. This will result in OA. short term interest rates higher than what would occur if no policy had been pursued. OB. unemployment rates higher than what would occur if no policy had been pursued. OC. real GDP lower than what would occur if no policy had been pursued. OD. inflation higher than what would occur if no policy had been pursued.
