Consider an economy with initial output lower than the natural level of output (Y") and negative inflation rate (deflation). a) Now by using the IS-LM-PC model show graphically and describe the deflation spiral and the dynamics of output, inflation and the real interest rate.  b) Discuss the constraint of the central bank and monetary policy to help the economy when the nominal interest rate is close to zero. What type of policies a central bank can implement in this environment to combat deflation?

Dynamic aggregate demand (AD) can be derived using the quantity theory of money. Label the equation so that it accurately expresses the quantity theory of money in dynamic form growth in the money supply -+ Answer Bank unemployment growth in velocity inflation real economic growth marginal propensity to save Suppose that the velocity of money is stable, 4% real economic growth is occurring, the rate of inflation is 4%, unemployment is 5.3%, and the marginal propensity to save is 3%. By how much is the money supply growing? Enter your answer as a percentage.

A country's central bank is engaging in monetary contraction, with M going from M0=40 to M1=20. Its economy is as follows. Goods: slc = 3 MPC = 0.7 G = 10 T = 9 Before the policy, the goods market equilibrium is at Y0 = 54. Financial: I = 18-200r Before the policy, the loans market equilibrium is at r = 4.25% and I = 9.5 Money: M0 = 40 P0 = 2 M/P = 0.02 / (r - Y/5000)^2 and finally, Labor: w = MPL = 0.5 * 4.5 * 16^0.5 / L^0.5 w = EP / P0 * L^0.5 Where workers currently expect the price level of EP=2. How does the monetary contraction directly and immediately affect the goods market?   There are four endogenous variables that adjust in response to shock/policy: Y, I, r, P. The policy variable of interest is M. Therefore, let's approach our solution by first recognizing that all other letters are just constants and plug them in. For example: Y = 2 + 0.5(Y-6)+7+I becomes Y = 12 + 2*I First, express the goods market as expenditure being a linear function of investment I of the form: Y = a…

Consider the classical AS-AD model with misperceptions. Assume that the economy is initially at its general equilibrium. Now, suppose the central bank considers an increase in the nominal money supply that is not anticipated by households or firms. b. How does the misperception theory work? c. Which of the three markets discussed in class is first affected (labor, goods, or asset market)? Explain and show graphically how this market is affected by an unanticipated increase in the nominal money supply.
