- A visual/graphic representation of how a decrease in consumer spending shifts the aggregate demand curve.The government announces a cut in the income tax rate. (a) Explain the multiplier effect by analysing how a typical consumer would react to this tax cut and which other decisions this reaction would trigger in the economy. (b) Use the AD/AS model to analyse the short-run effects of this policy on GDP and the price level in the economy. (c) What are the long-run effects of the tax cut?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?
- Use an aggregate demand (AD) and aggregate supply (AS) model to respond to the following questions. Explain your answers. (a) Under what conditions does a reduction in Aggregate Demand benefit the economy? (b) Show how stagflation impacts the economy in the short-run.A rightward shift in the aggregate supply curve with no change in the aggregate demand curve signals an economic expansion. True or False?Determinants of aggregate demand
- Suppose that consumers become pessimistic about the future health of the economy. What will happen to aggregate demand and to output? Show this using AD/AS graphs. What might the president and Congress have to do to keep output stable?Based on the picture, explain what happens to the aggregate demand. Describe your answer.Figure 1: Hayek’s (Classical) AD-AS Model Economics Online. (n.d.). Aggregate Demand. Retrieved from http://economicsonline.co.uk/Managing_the_economy/Aggregate_demand.html Hayek says that markets will heal themselves and that government should not intervene. How does the AD-AS model reflect Hayek’s idea that governments cannot increase real GDP beyond the level that the free market economy is able to produce? 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? Figure 2: Keynes’s AD-AS Model Economics Online. (n.d.). Aggregate supply. Retrieved from http://www.economicsonline.co.uk/Managing_the_economy/Aggregate+supply.html 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. In macroeconomics, the immediate short run is known as a length…
- Draw and fully label an AD-AS model. Describe the short-run aggregate supply (SRAS) curve and the long-run aggregate supply (LRAS) curve in words. Why is one of these curves horizontal and the other vertical?The consequences of climate change on the economy is a popular topic in the media. Suppose that a series of wildfires destroys crops in the western states at the same time a hurricane destroys refineries on the Gulf Coast. a) Using aggregate demand and supply analysis, explain how output and the inflation rate would be affected in the short and long runs. b) Show your answer graphically. Note: don't use chat gptPlease 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?
