S - I = NX

Net Capital Outflow = Trade Balance

Policies that increase investment, or decrease saving...

cause a trade deficit.

Policies that decrease investment or increase saving...

cause a trade surplus.

If money supply is stable...

the price level will be stable

If money supply rapidly increases...

the price level will rise rapidly.

Balanced Trade

Trade Surplus

when S - I = NX is positive
