QUESTION 2 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, long run: A reduction in personal income taxes shifts the demand curve to y=1530 – 6P. In the long run, the output is and the price level is

Suppose the aggregate demand (AD) and short-run aggregate supply (AS) schedules for an economy whose potential GDP (LRAS) equals to $2,700 are given by the table. Now suppose aggregate demand increases by $700 at each price level; for example, the new aggregate demanded at a price level of 50 now equals to $4,200. How will the shift in AD change the original output, price level, and employment? Name one factor that can cause the increase in aggregate demand and the shifting of the curve.
Suppose the aggregate demand (AD) and short-run aggregate supply (AS) schedules for an economy whose potential GDP (LRAS) equals to $2,700 are given by the table. 1.According to the macroeconomic perspectives, which zone is the short-run equilibrium falling into? 2.Would you expect unemployment rate of this economy to be relatively high or low, and explain why? What about the price level, a large or small concern, and why? 3. Now suppose aggregate demand increases by $700 at each price level; for example, the new aggregate demanded at a price level of 50 now equals to $4,200. Add a column of the new aggregate demanded at each price level in the above table. Plot a new AD curve (on the same graph you got in a.) and label the new equilibrium on the same graph.
Assume that (a) the price level is flexible upward but not downward and (b) the economy is currently operating at its full-employment output. Other things equal, how will each of the following affect the equilibrium price level and equilibrium level of real output in the short run?a. An increase in aggregate demand.b. A decrease in aggregate supply, with no change in aggregate demand.c. Equal increases in aggregate demand and aggregate supply.d. A decrease in aggregate demand.e. An increase in aggregate demand that exceeds an increase in aggregate supply.
Assume that the long-run aggregate supply curve is vertical at Y = 3.000 while the short-run aggregate supply curve is horizontal at P=1.0, . The aggregate demand curve is Y = 2(M / P) and M = 1,500. a. If the is initially in long-run equilibrium, what are the values of P and Y? Draw the equilibrium using AD and short and long run AS curves.
In Figure 1 above,how does the AD-AS model reflect the idea that governments cannot increase real GDP beyond an economy’s equilibrium level that the free-market economy is able to produce? Explain your answer. 2.1. In Figure 2 above, what are the factors that may cause the aggregate demand to shift from AD to AD1? What is the difference between demand pull inflation, cost push inflation, and recession? 2.2. Define and describe: the aggregate supply (AS) curve in the immediate short run. the aggregate supply (AS) curve in the short run. the aggregate supply (AS) in the long run. 3. Listen: Podcast: The Economics of Fiscal Stimulus - Econ EveryDay The Covid-19 pandemic shifted the aggregate supply and aggregate demand curves to the left. Did that increase or decrease real GDP, employment, and inflation rate? Explain your answer.
Explain, using the AD-AS model, the effect of an increase in investment in themacroeconomy on the equilibrium price level and the equilibrium level of output.(10)Q.1.2 Can demand management policies be used to combat stagflation? Explain youranswer.(2)Q.1.3 Identify three ways in which aggregate supply could decrease in an economy.
Please explain why the long-run aggregate supply curve is vertical. What variable causes the short-run aggregate supply curve to shift? Please identify whether an increase in that variable will cause the short-run aggregate supply curve to shift to the right or to the left. What is the relationship among the AD, SRAS, and LRAS curves when the economy is in macroeconomic equilibrium?
We can analyze the macroeconomic effects of Hurricane Katrina using the aggregate supply (AS) and aggregate demand (AD) diagram. The horizontal axis measures real GDP, a measure of the nation’s output that removes the effects of inflation. The vertical axis measures the price level (the average level of output prices). Consider Katrina’s effect of “cost shocks” – unexpected changes in the prices of important inputs (assume LRAS is unchanged). For example, Katrina unexpectedly choked off oil, natural gas, and refined gasoline supplies from the Gulf region, placing upward pressure on energy costs. The hurricane also shut down factories and businesses, reducing the nation’s productive capacity. Therefore, the effect of the higher energy prices and reduced productive capacity is to shift the __________ curve(s). Consider how the government’s fiscal policy response affects the economy. Recall that both individual consumers’ purchases and government purchases are included in aggregate…
The figure given below represents the equilibrium real GDP and price level in the aggregate demand and aggregate supply model. Suppose that AD and ASp represent the initial aggregate demand and aggregate supply in the economy. Figure 18 Refer to Figure 18. Movement of equilibrium from point D to point B could be initiated by: A) a stock market crash that undermines consumer confidence. B) a tax code changes that negatively affect investor expectations. C) a sharp decrease in government spending. D) a higher net exports because of economic expansion in European countries. E) a technological advancement.
The aggregate demand and the aggregate supply model allows us to examine how a variety of events can affect the economy. Explain the shape of aggregate demand curve. How do Classical and Keynesian economists differ in their view of the aggregate supply curve? In your own words, discuss which of the four sources identified with aggregate demand has caused a change in the aggregate demand for a product or service you or your employer use. Share the effect that source has had on how you or your employer contribute to the measurement of aggregate demand.
The imaginary country of Harris Island has the aggregate supply and aggregate demand curves as Table 24.3 shows. a. Identify the (i) equilibrium basing from the AD/AS diagram attached. b. Would you expect unemployment in this economy to be relatively high or low? c. Would you expect concern about inflation in this economy to be relatively high or low? d. Imagine that consumers begin to lose confidence about the state of the economy, and so AD becomes lower by 275 at every price level. Identify the new aggregate equilibrium. e. How will the shift in AD affect the original output, price level, and employment?
Please see below. These are true or false questions. 1). The aggregate supply curve will shift left as the price of key inputs rises, and will shift out to the right if the price of key inputs falls. 2). Long-term economic growth is illustrated in the AD/AS framework by a gradual shift of the aggregate supply curve to the left.
