How does an increase in desired national saving in a large open economy affect the world real interest rate?
Large Open Economy:
A large open economy is one that engages in free trade and free capital mobility, but its relative size of the economy is large enough to influence the world interest rate. This contrasts with a small open economy that takes world interest rate as given.
