# IS / LM Analysis

A macroeconomic model of Econoland can be summarized as follows:

C = 100 + 0.5(Y - T)

I = 0.25 Y - 500(r)

G0 = 300

T0 = 100

X0 = 200

M0 = 200

M D = 10Y - 20,000(r)

M S0 = 200

Part a - Derive the equation for the IS Schedule

Part b - Derive the equation for the LM Schedule

Part c - Calculate the equilibrium interest rate (r)

Part d - Calculate the equilibrium level of income (Y)

#### Solution Preview

Part a - Derive the equation for the IS Schedule

The IS Equation

Y = C + I + G + (X - M)

Y = 100 + 0.5(Y - 100) + 0.25 Y - 500(r) + 300 + (200 - 200)

Y = 350 + 0.75Y - 500(r)

0.25 Y = ...

#### Solution Summary

IS / LM Analysis is achieved.
