Suppose an economy is represented by the following equations.

Consumption function                                     C = 300 + 0.8Yd

Planned investment                                                        I = 400

Government spending                                                   G = 500

Exports                                                                       EX = 200

Imports                                                                   IM = 0.1Yd

Autonomous Taxes                                                        T = 500

Marginal Tax Rate                                                               t=0.25

Planned aggregate expenditure         AE = C + I + G + (EX - IM)

 

By using the above information calculate the equilibrium level of income for this economy and explain how multiplier changes when we have an  open economy
