Suppose an economy begins at AD and AS in long-run equilibrium with real GDP equal to Y*; the price level is stable at Po. a. Suppose the central bank announces that it will implement an expansionary monetary policy that will shift the AD curve up by 5 percent. Does the shift of the AS curve following this announcement depends on whether workers and firms believe the central bank's announcement? Explain. OA. Yes. Workers' and firms' expectations of inflation put pressure on nominal wages, which is what causes the AS curve to shift. Workers' and firms' expectations of inflation will not change if they do not believe the announcement. OB. No. The bank's announcement will affect the shift of the AS curve, regardless of whether workers and firms believe it. Yes Workers' and firms' expectations of real interest rates put pressure

Consider the Keynesian sticky wage model. Assume that the economy is operating close to, but not at, its zero lower bound (ZLB). Discuss the following: 1. Could a negative shock to the IS curve make the ZLB bind? Explain and illustrate graph- ically. 2. Could a shock to current productivity z make the ZLB bind? What would need to be the sign of this shock to make the ZLB bind? 3. In the data, in most episodes where the ZLB binds (the US in the wake of the Great Recession, Japan during the 1990s, and the US during the Great Depression), output is low. Given this, would a supply shock as the reason for a binding ZLB make empirical sense? 4. Intuitively, explain why changes in government spending have a bigger effect on output at the ZLB than away from it.

Owing to the global rise of fertilizer prices in 2022 (in turn caused by the Russian invasion of Ukraine), the country experienced a shortage in some agricultural commodities. Using the AS-AD model, which of the following is an anticipated effect of this phenomenon? O a. Aggregate demand will rise in the short run. b. Aggregate demand will be higher than initial level in the long run. O C. Prices will quickly rise in the short run. O d. Prices will fall even below the pre-supply shock level in the long run.

2. The graph below shows the AD-AS model in short-run equilibrium at price level Po and level of real GDP at Yo. Label the following: AD, SRAS, LRAS, Po and Yo. P Y A. Is this SR equilibrium a recessionary gap or an inflationary gap? Why is the undesirable? B. Assume Congress and the President decide to act. How would you suggest they alter each of the following (1,↓↓, or no change)? - Taxes - Transfer Payments -Government Spending C. Show the effects of these changes in the space above. Assume this intervention brings the economy back to potential GDP. D. As the economy moves from Yo to Yp, what happens to the following (1,↓, or no change)? - Real GDP - the unemployment rate - The price level - the rate of inflation
According to the Keynesian model, which of the following would NOT increase aggregate demand? Government expands its social projects and increases taxes to balance the budget а. O b. A decrease in the number of employees in the government agencies c. Government drops the taxes for private businesses O d. Government establishes a new agency that helps the unemployed to find a job е. Government changes the laws whereby the tax of the interest earned becomes changes from a positive number to zero.
When a supply-side shock is assumed to be permanent: O only the LRAS curve shifts. O only the SRAS curve shifts. O both the LRAS curve and the SRAS curve shift. O nither the LRAS curve nor the SRAS curve shifts.
Draw and properly label an AD-AS model to show Keynesian, intermediate, and neoclassical zones. Then, briefly explain the levels of unemployment, inflation and real GDP in each zone, and also confirm whether all three goals of a macro economy are being achieved in each zone. 2. Draw and properly label the AD-AS graphs or one AD-AS graph to show recessionary and inflationary gaps. Then, discuss in detail how Keynesians suggest that recessionary and inflationary gaps be closed. 3. Draw and properly label AD-AS graphs or one AD-AS graph to show recessionary and inflationary gaps. Then, discuss in detail how neoclassicals suggest that recessionary and inflationary gaps be closed.

Suppose Chino is a closed economy. A large portion of the work force has joint astrong labor union. As such, the nominal wages of most workers are downwardrigid.Suppose most households lose their wealth in a recent clash of the stock market.How would the price and output level of Chino be affected in the short run?Explain by using the AD-AS model. Particularly, use the sticky-wage model ofaggregate supply to explain the magnitude of the effects on price and output.

n the AD-AS model, assume that an economy’s aggregate demand, denoted by QD=400−P, and SR aggregate supply, denoted by QS=P, currently intersect at price level = $200 and the full employment output level = 200. What curve would have shifted if a new short-run equilibrium were to occur at an output level of 300 and a price level of $300? Group of answer choices SRAS shifts leftward. AD shifts leftward. SRAS shifts rightward. AD shifts rightward.
