3. Many economists believe that the financial panic associated with Lehman Brothers' bankruptcy I September 2008 turned what was until then a relatively mild recession into the Great Recession, since it added severe financial frictions (an increase in f) to adverse demand shocks (falling c, ;). a. Use the AD-AS model to compare two scenarios: one with just the negative demand shocks, the other with the added financial frictions (i.e., all three shocks). You should have one graph for each scenario (2 graphs). b. Suppose that f = 6%, c = -1%, and ; = -1%. The other parameter values in the model are: i = 2,6 = m = = 0.5. Using the equilibrium AD-AS equations, compare the initial changes in inflation and the output gap for the two scenarios in part (a). That is, compute it and i in each scenario. 3.
