IS-LM-FX Model with Floating Exchange Rate... For each of the following situations use the IS-LM-FX model to illustrate, first, the effects of the temporary shock, and then the policy response. (Note: Assume the central bank responds by using monetary policy to stabilize output (i.e. to keep it at the initial equilibrium).) Label A the initial equilibrium, B the short-run equilibrium without policy response, and C the equilibrium after the response of the central bank. For each case, state the effect of the shock on the following domestic variables (increase, decrease, no change, or ambiguous): Y , i, E, C, I, T B. Assume a flexible exchange rate. a All else equal, the real demand of money falls. b All else equal, there is an increase in the expected nominal exchange rate.
