- For each of the three theories for the upward slopeof the short-run aggregate-supply curve, carefullyexplain the following:a. how the economy recovers from a recession andreturns to its long-run equilibrium without anypolicy interventionb. what determines the speed of that recoveryExplain whether each of the following events shiftsthe short-run aggregate-supply curve, the aggregatedemand curve, both, or neither. For each event thatdoes shift a curve, draw a diagram to illustrate theeffect on the economy.a. Households decide to save a larger share of theirincome.b. Florida orange groves suffer a prolonged period ofbelow-freezing temperatures.c. Increased job opportunities overseas cause manypeople to leave the country.a. What are the short-run equilibrium real GDP and price level in 2019?b. What is the long-run equilibrium real GDP?c. Is the short-run macroeconomic equilibrium a full-employment equilibrium, belowfull-employment equilibrium, or above full-employment equilibrium?d. In transition to the long run, how would the wages in this economy change?e. Following from d, explain how would the short run supply curve move to its long runposition, as the changes in the nominal wages take effect.f. What will the long run price level be?
- When the economy is experiencing a recession, why would aneoclassical e conomist be unlikely toargue for aggressive policy to stimulate aggregate demandand return the economy to full employment? Explain your answer.Assume an economy operates in the intermediaterange of its aggregate supply curve. State thedirection of shift for the aggregate demandor aggregate supply curve for each of thefollowing changes in conditions. What is theeffect on the price level? On real GDP? Onemployment?a. The price of crude oil rises significantly.b. Spending on national defense doubles.c. The costs of imported goods increase.d. An improvement in technology raises laborproductivity.For each situation below, analyse whether it shifts the aggregate demand (AD) curve, the aggregate-supply (AS) curve, both, or neither. Then, if it does shift a curve, construct the AD-AS diagram to show the effect on the economy in the long-run. a) One extraordinary impact of COVID-19 pandemic to the U.S. economy is a massive increase in saving. U.S. recorded nearly tripled saving over the first two quarters of 2020, from $1.59 trillion annualized in the first quarter to $4.69 trillion in the second, which is by far the biggest increase in modern history. b) The prolonged monsoon rain has caused the production of vegetables in Cameron Highlands fell by about 30%. It has severely impacted a lot of crops, including fruits and flowers. Besides, labor shortages due to the pandemic makes the matters worse.
- Suppose an economy is in long-run equilibrium.a. Use the model of aggregate demand andaggregate supply to illustrate the initialequilibrium (call it point A). Be sure to includeboth short-run aggregate supply and long-runaggregate supply.b. The central bank raises the money supply by5 percent. Use your diagram to show whathappens to output and the price level as theeconomy moves from the initial equilibrium to thenew short-run equilibrium (call it point B).c. Now show the new long-run equilibrium (call itpoint C). What causes the economy to move frompoint B to point C?d. According to the sticky-wage theory of aggregatesupply, how do nominal wages at point Acompare with nominal wages at point B? How donominal wages at point A compare with nominalwages at point C?e. According to the sticky-wage theory of aggregatesupply, how do real wages at point A comparewith real wages at point B? How do real wages atpoint A compare with real wages at point C?f. Judging by the impact of the money…Assume the supply of loans decreases by 25%, even though the economy isinitially in both short-run and long-run macroeconomic equilibrium. Describe the effects, in the short-run and in the long-run, onthe following: a) Aggregate outputb) Aggregate price levelc) Interest rate Answer all question step by step.Answer Must be correct.Illustrate and interpretthe short-run andlong-run aggregatesupply curves
- Review the problem in the Work It Out titled"Interpreting the AD/AS Model." Like the informationprovided in that feature, Table 24.2 shows informationon aggregate supply, aggregate demand, and the pricelevel for the imaginary country of Xurbia. a. Plot the AD/AS diagram from the data. Identifythe equilibrium.b. Imagine that, as a result of a government taxcut, aggregate demand becomes higher by 50 atevery price level. Identify the new equilibrium.c. How will the new equilibrium alter output? Howwill it alter the price level? What do you thinkwill happen to employment?What does the intersection of the AD and AS curves signify? Contrast the shor-turn aggregate supply (SRAS) curve from the long-run aggregate supply (LRAS) curve. (11.2)Assume an ecomy operates in the intermediate range of its aggregate supply curve. State the direction of shif for the aggregate demand curve or aggregate supply curve for each of the following changes in conditions. What is the effect on the price level? On real GDP? On employment?
