What is the difference between the Keynesian zone, neoclassical zone, and intermediate zone in the AD/AS model? For each, predict the impact that an increase in aggregate demand would have on the price level relative to real GDP in each of those zones. How does the AD/AS model explain economic growth, recessions, as well as changes in unemployment and inflationary pressures?
The total expenditure in Macroland begins with these initial levels (in trillions of dollars): autonomous consumption=1, Investment = 2; Net Exports = 0, T=2, and MPC = 0.75. Assume that equilibrium has been achieved. Suddenly there is an external shock and as a result investment goes down to 1. What is the change in GDP? Use the base model to answer this question.

QUESTION 1 Consider the aggregate supply-aggregate demand (AD-AS) model that we saw in class. Assume that prices are fixed in the short run and are fully flexible in the long run. The initial full-employment level of output is Y=900 and the initial price level is P=100: The aggregate demand curve is given by Y= 1500 - 6P: Scenario 1, short run: A reduction in personal income taxes shifts the demand curve to Y=1530 - 6P. In the short run, the output is and the price level is Note: Type in your answer rounded to two decimal places, i.e., your answer must be of the form "999.99". I will not be able to fix correct answers that were entered incorrectly, such as "999.999" or "999,99" or "999".

The context is a large negative shock to autonomous consumption in an open economy. You may assume the economy is initially at a medium run equilibrium. Aggregate demand can decline for many reasons. Give a specific example of when you would choose to model the onset of a recession by a fall in autonomous consumption and explain why. Use graphs if possible.
Consider the following AD/AS diagram of the macroeconomy, with LRAS shown as the vertical curve, AD as the downward sloping curve, and SRAS as the upward sloping curve. First, place a point at the current equilibrium. Then, suppose the government wants to stimulate the economy to restore it to long-run equilibrium by cutting taxes. Draw a new curve that shows the impact of this policy change. (You'll have to determine which, but draw it so that it reflects a parallel, vertical shift in one of the existing curves. Make sure that it's the same size as the ones shown here using the segment tool.) Finally, place a point at the new equilibrium using the point tool.
Which of the following is implied by a rightward shift in the economy's AS curve? There is a demand shock. The same output will be produced, but only at a higher price level. At any given price level, a higher level of output will be supplied. At any given price level, a lower level of output will be supplied.
Consider a fictional economy that is operating at its long-run equilibrium. The following graph shows the aggregate demand (AD) curve and short-run aggregate supply (AS) curve for the economy. The long-run aggregate supply curve is represented by a vertical line at the potential GDP level of $6 trillion. The economy is initially producing at potential GDP. Suppose that fiscal authorities decide to decrease marginal tax rates. Assume that this change in marginal tax rates is perceived as a long-term change. Shift the appropriate curves to illustrate the supply-side view of the fiscal policy effect on output and the price level. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. 120 Potential GDP AS 100 PRICE LEVEL 60 80 60 40 40 20 20 0 0 2 4 6 8 AD 10 12 QUANTITY OF OUTPUT (Trillions of dollars) AD 1 AS Potential GDP True or…
The figure below is a part of the AD-AS model as a description of the current situation of an economy. PA=$10 P YA=4000 Y a) Find the short-run equilibrium (i.e. the real output and the price level thereof) of this economy. b) If the natural level of output is 3500, which one will be higher, the unemployment rate at point A, or the natural unemployment rate? Explain. c) Give two reasons as to why the short-run aggregate supply is upward sloping. d) Suppose the government takes no action about the situation indicated above. Explain, with the help of a figure properly labeled, what will happen in this economy in the long run. e) Describe the two kinds of macroeconomic policies that can be used in the situation described before part c). Indicate clearly in your description whether each policy is to the aggregate demand or aggregate supply or Further, give reason(s) as to why the government may want to use these policies rather than doing nothing.

The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion. Suppose a stock market boom increases household wealth and causes consumers to spend more. Shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the stock market boom. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) In the short run, the increase in consumption spending associated with the stock market expansion causes the price level to the price level people expected and the quantity of output to the natural level of output. The stock market boom will cause the unemployment rate to the natural rate of unemployment in the short run. Again, the following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion, before the increase in consumption spending associated with…
Consider a closed economy, where wages are sticky in the short run. The consumption function is C = co+c₁(Y-T), where the marginal propensity to consume c₁ is equal to 0.8. Initially the economy is in equilibrium at Y = Y* and P = Pº, where Pe is the price level that was expected when agents agreed their fixed nominal wage contracts. The short-run aggregate supply curve (SRAS) is horizontal. Suddenly the government increases government spending G by $200. For the following questions, if you think a variable goes up by (say) $50, just enter 50 as your answer. If you think a variable goes down by $50, enter -50 as your answer. If you think a variable doesn't change at all, enter 0 as your answer. 10. By how much will output Y change in the short run? 11. By how much will consumption C change in the short run? 12.
