- What is the key difference between the IS-MP-PC model and the AD/AS model? O In AD/AS model, the government can not borrow In AD/AS model, the central bank can not change the interest rate O In AD/AS model, the central bank sticks to a rule O In AD/AS model, the government can not change its expenditureSuppose 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…Using AS and AD curves to illustrate, describe the effectsof the following events on the price level and on equilibriumGDP in the long run assuming that input prices fullyadjust to output prices after some lag:a. An increase occurs in the money supply above potentialGDPb. GDP is above potential GDP, and a decrease in governmentspending and in the money supply occursc. Starting with the economy at potential GDP, a war inthe Middle East pushes up energy prices temporarily.The Fed expands the money supply to accommodate theinflation.
- The slope of the ADTT curve is determined by: O a. The monetary policy of targets and instruments of the central bank O b. All of the above O c. The expenditure multiplier O d. The changes in and aggregate expenditure when interest rates changeIn 2006, the Federal Reserve System decides to lower the money supply and raise interest rates in order to combat inflation, which caused investment spending for housing to fall. As a result, a change in investment spending for housing shifts the AS curve to the right, causing equilibrium price level to fall and equilibrium Real GDP to increase. O AS curve to the left, causing equilibrium price level to rise and equilibrium Real GDP to decrease. AD curve to the left, causing equilibrium price level to fall and equilibrium Real GDP to fall. AD curve to the right, causing equilibrium price level to rise and equilibrium Real GDP to increase.. Suppose that there is an increase in the price of housing, which the central bank judges is atemporary asset price bubble. In the New Keynesian model, determine the central bank’s optimalresponse to this asset price increase, using diagrams. Discuss your results.
- On June 5, 2003, the European Central Bank acted to decreasethe short-term interest rate in Europe by half a percentagepoint, to 2 percent. The bank’s president at the time, WillemDuisenberg, suggested that, in the future, the bank could reducerates further.

- Explain if, and why, you agree, or do not agree, with the following statement [when answering, assume that, in each time period, the economy is described by a static IS-LM model, with consumption and investment depending on contemporaneous variables only]:"In a closed economy wherke the central bank chooses the money supply, the prices of stocks at time t, €Qt, will unambiguously rise if, from time t onwards, government purchases of goods and services, G, go up".In the basic New Keynesian model, suppose that there is an increase in government spending. • First, suppose that the central bank does nothing (accommodates the shock). Illustrate onthe graphs and explain what will be the effects on inflation and output? • Second, suppose that economy initially has inflation equal to the central bank’s inflationtarget and an output gap of zero.
