Question
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.

- 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". In case the last digit in the correct answer is zero, e.g., "999.90" or "999.00", Blackboard may automatically delete it and you should not do anything about it. In case of percentages, do not type in the percentage symbol "%".arrow_forwardAssuming that there is no government spending or trade, an economy’s GDP is the sum of domestic consumption C and investment I, i.e. Y = C+ I Assume that I is unaffected by GDP Assume the consumption function is C = c0 + c1Y In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which FIVE of the following statements are correct? Select one or more: A. If the economy above is a demand-driven economy, then the equilibrium solution for Y is given by Y = m(c0 + I), where m = 1/(1 - c1) is the multiplier. B. if c1 = 0.8 the multiplier is equal to 1/0.8= 1.25 C. if c1 = 0.75 the multiplier is equal to 4 D. assume c0 =100, I=50, c1=0.6. The equilibrium value of Y in a demand-driven economy is 300. E. Assume that Y is initially 400, I is initially 100, and the multiplier is 2.5. I increases by 10%. The multiplier implies that in equilibrium Y will increase by 25%. F. The higher is c1 the larger is the multiplier G. If consumers…arrow_forwardPrice Level AD1 AD₂ AD2 Real Domestic Output, GDP Refer to the accompanying graph.

- Hello Can you help me out. Use the AD/AS model to illustrate the following. Draw 6 graphs by hand. Show how the AD or the AS curve shift and in what direction (left or right). Also state what happens to equilibrium real GDP (Y), employment, and the equilibrium price level. [Note: Use the SRAS curve, not the LRAS.] A. an increase in government spending and/or transfer payments B. restrictive fiscal policy C. expansive monetary policy D. increase in investment according to Keynesians E. increase in investment according to supply-side economists F. a stock market crasharrow_forwardNotice the major differences between our Keynesian Cross (in your chapter 9 appendix) and the Macro Equilibrium (AS and AD) diagram?

- Draw and carefully describe a graph that utilizes the Aggregate Demand/Aggregate Supply model that would illustrate the state of the aggregate economy in the United States at the very beginning of 2020 before the start of the pandemic and the 2020 recession. Make sure that you explain your graph in your own words. You should draw your own AD/AS graph which you can then embed into your post. Your graph needs to be clearly labeled and explained in some detail. Make sure that your graph includes an aggregate demand (AD) curve, a short run aggregate supply (SRAS) curve, and a long run aggregate supply curve (LRAS, Potential GDP) curve. You should clearly label both axes of the graph.arrow_forwardWhich of the following is a major difference between the AD-AS model and the dynamic AD-AS model? The dynamic AD-AS model assumes OA. AD only includes consumption, investment, and government purchases, while the AD-AS model assumes AD includes consumption, investment, government purchases and net exports. B. the SRAS is stable and will not shift, while the AD-AS model assumes the SRAS can only change with an exogenous event such as oil price changes. OC. the economy does not experience long-run growth, while the AD-AS model assumes there is constant inflation in the economy. OD. potential GDP increases continually, while the AD-AS model assumes the LRAS does not change.arrow_forwardlet's consider the AS/AD model. furthermore, assume two events happen at the same time: government conducts contractionary fiscal policy and the global price of energy (oil) falls. show the effects of these two events in a graph and explain what will happen to the GDP and price level?arrow_forward
- What would the LM curve look like in a classical world? If this really were the LM curve that we thought best characterized the economy, would we lean toward the use of fiscal policy or monetary policy?

This graph depicts the AD-AS model, which involves the Aggregate Demand curve (AD), Aggregate Supply curve (AS) and Long Run Aggregate Supply curve (LRAS). Our assumptions with this model match those from class. LRAS AS AD Assume in the multiple choice questions below that our starting point is pt A. Assume that in the months leading up to a major election, the Federal government enacts legislation that significantly increases government spending. Assume further that government pays for this spending by increasing the money supply. Based on our discussion of the self-correcting mechanism, how would this policy affect the graph in the short run and long run? Itranscript Oa. in the short run, AD will increase, but over the long run, AS will eventually shift upward as workers begin to ask for cost of living increases from their employers Ob. in the short run, AD will increase, but over the long run. AS will eventually shift leftward as workers…arrow_forward
