Consider the classical AS-AD model with misperceptions. Assume that the economy is initially at its general equilibrium. Now, suppose the central bank considers an increase in the nominal money supply that is not anticipated by households or firms. a. How does the misperception theory work? b. Which of the three markets is first affected (labor, goods, or asset market)? Explain and show graphically how this market is affected by an unanticipated increase in the nominal money supply. c. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the short-run equilibrium. d. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the long-run (general) equilibrium.
The theory of macroeconomic fluctuations is also the short run model of the macroeconomy and assumes that business firms will supply any amount of output demanded by the economy TRUE OR FALSE?
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.
Based on the picture, explain what happens to the price level. Describe your answer.
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.
The economy of Winterspring is currently in an equilibrium depicted by point E, on the graph. Economy of Winterspring Now suppose that there is a demand shock in the economy and the AD curve shifts from AD, to AD,, as shown by the graph. 2400- 2.200- AS Suppose that there is no monetary validation. 2.000- 1.800- Using the point drawing tool, show the short-run equilibrium that the economy will move into in this case.

For Shock C: Suppose the economy starts in the long run equilibrium. Illustrate changes that the shock will cause in the short run (using AD-SRAS). Explain why each curve shifts. Determine how the price level and output will be affected in the short run. Mark the output gap on the diagram. Is the output gap positive or negative? Is the economy is booming, or is it in a recession? On the same diagram illustrate how the economy will adjust to the shock in the long run and explain the mechanism. Determine how the price level and output will be affected in the long run. C. Firms expect an economic boom in the coming years As a result of this shock, in the short run the (SRAS Curve/AD Curve) will shift? In consequence, in the short run prices and output will? In the short run, there will be a ? (negative/postive) output gap,which means there will be a ? (boom/recession) As time passes, because of high unemployment the wages in the economy will? (decrease/increase) As a result,…
Use the AS-AD model to analyze the impact on the U.S. economy as a result of each of the listed events. Mention if AD and/or AS shift and in which direction. Also explain what the country will experience with respect to increase or decrease in short-run equilibrium real GDP and increase or decrease in the equilibrium price level. For each event, assume that the economy is originally in a full- employment equilibrium, mention if in the new equilibrium there is a recessionary gap or an inflationary gap. A) Congress raises income taxes. B) The Federal Reserve decreases the target for the federal funds rate. C) Migration to the US increases the working- age population. DJ Appreciation in the international value of the dollar.
Do you believe that the Hayek’s classical AD-AS model explain the factors that cause changes (shifts) in AS realistically? Why or why not?

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.
