The Mundell-Fleming Model

Add a foreign sector to the IS/LM Model.

The Augmented IS/LM Diagram

The IS Curve

Let X denote exports, and let Z denote imports.  Y = C + I + G + X - Z and Y = C + S + T.

For comparison:  The IS Curve without foreign transactions.

The LM Curve

(here)

The BP Curve

A zero in the balance of payments.  X - Z is the trade balance.  F is the net capital inflow.  X - Z + F = BOP, where BOP is balance of payments, which equals net official reserve transactions.  X - Z + F = 0
