The macroeconomy is depicted by the graph to the right. a. Suppose that AD has changed due to higher real interest rates. Using the line drawing tool, draw this new line and label it 'D₁". Carefully follow the instructions above, and only draw the required objects. b. The new short-run equilibrium price level has and real GDP has c. Thus, in the short run it is d. The cost of producing below the full employment level of real GDP is to produce below the full employment level of real GDP.

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.
The figure to the right shows an economy in a short-run equilibrium at point A Using the three-point curved line drawing tool, illustrate cost-push inflation. Properly label this curve Note: Carefully follow the instructions above and only draw the required object. Which of the following is most likely to cause the cost shock that shifts the AS curve consistent with cost-push inflation? A. A surge in the price of crude oil. OB. A tax increase on households. OC. An increase in the size of government. OD. A flood of new immigrants. Price level, Pa AD₂ Yo Aggregate output (income), Y AS du
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.

Consider an AS AD diagram. What would happen in the model if Energy prices increased? Group of answer choices a. AD shifts right and prices increase while real GDP increases b. AS shifts left and prices increase while real GDP decreases c. AS shifts right and prices decrease while real GDP increases d. AD shifts left and prices decreases while real GDP decreases
Question 1. In the AD-AS model with an upward-sloping AS curve, a decrease in oil prices will: A. increase prices and output. B. increase prices and decrease output. C. decrease prices and increase output. D. decrease prices and output. E. decrease prices but have no effect on output. Question 2 Improvements in the matching efficiency in the labour market always lead to: A. lower unemployment rate. B. lower vacancy rate. C. higher vacancy rate. D. no effect on the vacancy rate. E. Both A and D.
3. Using aggregate demand and aggregate supply analysis, show the effects of the following (Assume neo-Keynesian AD and AS curves.): a. deflation b. an increase in investment spending c. an increase in the average wage rate d. an income tax cut
Suppose the economy is initially at K. Which of the following statements best explains how the economy responds to restore long-run macroeconomic equilibrium? Select one: a. Over time, the aggregate demand curve will shift to the right until long-run equilibrium is restored at J and the gap is closed. b. Rising unemployment puts pressure on nominal wages to fall. The SRAS curve shifts right to SRAS1 closing the gap at H. c. In response to rising prices, firms will increase production moving along SRAS2 until long- run equilibrium is restored at J and the gap is closed. d. Rising unemployment puts pressure on nominal wages to fall. Firms employ more workers moving along SRAS2 until long-run equilibrium is restored at J and the gap is closed.

nd 2. Assume that the economy starts at medium run equilibrium. Now let the government increase taxes. Using AS and AD curves, show the impact on output and prices in the short run and the medium run.
Suppose the economu is operating at less than full employment. an increase in aggregate demand will result in: A. An increase in the general price level and perhaps an increase in the general price level B. A decrease in the general price level and perhaps a decrease in aggregate demand C. An increase in aggregate output and perhaps a decrease in the general price level D. An increase in the general price level and perhaps a decrease in aggregate output
