The Short-Run Aggregate Supply Curve (AS) is given by: y=20pAnd the Short-Run Aggregate Demand Curve (AD) is given by: y=25,000−20p Suppose instead that the Central Bank wanted to take action to keep the price-level completely stable. This would entail keeping it constant at its current rate. Suppose also that the Central Bank targets the interest rate directly. Suppose also that: • The Marginal Propensity to Spend is 0.75. • Every 1% increase in the interest rate leads to a decrease in Autonomous Consumption of 250 and a decrease in Autonomous Investment of 250. How much would the Central Bank need to change the current interest rate in order to keep the price level from changing through the medium-term as this output gap closes in the economy?
Assume that (a)the price level is flexible upward but not downward and (b) the economy iscurrently operating at its full-employment output. Other things equal, how willeach of the following affect the equilibrium price level and equilibrium levelof real output in the short run?· An increase in aggregate demand.· A decrease in aggregate supply, with no change in aggregatedemand.· Equal increases in aggregate demand and aggregate supply.· A decrease in aggregate demand.· An increase in aggregate demand that exceeds an increase inaggregate supply.
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.
10. Which of the following are reasons why the short-run Aggregate Supply curve shown in the right-hand diagrams may be vertical? a) The economy at this level of real GDP would be operating beyond the full-employmetn level. b) Inflationary expectations have set-in so, the owners of resources are acting on these inflationary expectations and insisting on higher resource prices in anticipation of future products price inflation. c) Short-run Aggregate Suply in the Classical model is always constant. d) All the above e) Only (a) and (b) are true. f) None of the above.

1. In the following table, determine how each event likely effects potential output (a.k.a., long-run aggregate supply). Direction of Potential Output Shift Event Left Right No Shift The government allows more immigration of working-age adults. For environmental and safety reasons, the government requires that the country’s nuclear power plants be permanently shut down. An investment tax credit increases the rate at which firms acquire machinery and equipment. 2. In the following table, determine how each event affects the position of the aggregate demand curve. Direction of AD Curve Shift Event Left Right No Shift A decrease in consumer confidence (suggests people believe a contraction/recession coming) A decrease in individual income tax rates An increase in the value/price of housing 3.

Assume that a country’s economy is in a short-run equilibrium and the actual unemployment rate is lower than the natural rate of unemployment. Using a correctly labeled graph of the long-run aggregate supply curve, short-run aggregate supply curve, and aggregate demand curve, show each of the following. Current price level, labeled PL1, and current output level, labeled Y1 The full-employment output level, labeled YF. What open-market operation can the country’s central bank use to move the economy toward its long-run equilibrium? Use a correctly labeled money-market graph to show how the country’s central bank action to move the economy toward its long-run equilibrium affects the equilibrium nominal interest rate in the short run. Based on the interest rate change from part (c), will each of the following increase, decrease, or remain the same in the short run? Real output. Explain.
