THIS IS THE GENERAL EQUILIBRIUM PROBLEM THAT I PROMISED. YOU FIRST SOLVE FOR THE INITIAL EQUILIBRIUM AS POINT A. WE CONSIDER TWO DIFFERENT AND SEPARATE SHOCKS (I CALL THEM SCENARIOS). THE FIRST SHOCK IS TO THE IS CURVE, THE SECOND SHOCK IS A ‘LM’ SHOCK. AGAIN, WE CONSIDER THESE SHOCKS SEPARATELY SO THAT AFTER YOU COMPLETE SCENARIO 1 (THE IS SHOCK), WE GO BACK TO THE ORIGINAL CONDITIONS AND CONSIDER THE SECOND SCENARIO WHICH IS THE ‘LM’ SHOCK. Consider the...
