. Consider the following IS-LM model (all amounts are in millions of dollars):
C = 50 + 0.6 YD
T = 20
G = 300
I = 450 + 0.2 Y - 1500 i
- Derive the IS equation in the form Y = function (i, ….).
- The central bank sets an interest rate of 10%. What is the full SR model eqm Y? Use (M/P)d=3Y– 4000i to calculate what the real Ms is at this full SR eqm. Graph this eqm in 3 separate graphs: i-Y, i-(M/P), and Z-Y spaces. You may link these graphs up or leave them separate.
- Suppose Congress decides to decrease G from 300 to 295, cet. par. Provide a specific $ amount for the new eqm Y. Show this “shock,” with its appropriate name, in the 3 graphs of part b. above. Present and discuss all changes in all components of IS and LM using directional arrows.
