Which of the following describes the use of Keynesian macroeconomic policy to resolve an inflationary gap problem in the economy? a) Unemployment, resulting from the short-run product markets equilibrium being below Long-run Aggregate Supply (LRAS), causes wages to decline, which increases short-run Aggregate Supply (AS), until long-run equilibrium is attained at full employment level of income and a lower price level. b) Government spending is increased, increasing Aggregate Demand (AD) to a level sufficient to attain long-run equilibrium at full employment level of income and a higher price level. c) In attempting to produce beyond the economy's natural level of GDP, producers bid up wages and prices of other resources, causing the short-run Aggregate Supply (AS) to decrease to the point where long-run equilibrium is restored. d) Taxes are increased reducing Aggregate Demand (AD) to a level consistent with full employment.

Suppose the economy is initially at K. Which of the following statements best explains how the economy responds to restore long-run macroeconomic equilibrium? Select one: a. Over time, the aggregate demand curve will shift to the right until long-run equilibrium is restored at J and the gap is closed. b. Rising unemployment puts pressure on nominal wages to fall. The SRAS curve shifts right to SRAS1 closing the gap at H. c. In response to rising prices, firms will increase production moving along SRAS2 until long- run equilibrium is restored at J and the gap is closed. d. Rising unemployment puts pressure on nominal wages to fall. Firms employ more workers moving along SRAS2 until long-run equilibrium is restored at J and the gap is closed.

Assume a Keynesian AS curve. In the short run, when there is a large negative output gap (AD-AS intersection far to the left of the full employment level of output), then 1.expansionary demand management policy is likely to be highly inflationary 2.expansionary demand management policy does not cause much inflation 3.the government should use contractionary demand management policy 4.contractionary demand management policy is likely to be highly inflationary
