PPP holds in the long term
IRP holds in the short term
What about
URIP (uncovered interest rate parity)?
International Fisher's relations?作者: RepoToronto 时间: 2011-7-11 15:17

Not a requirement, but empirical data show it does so.

Covered Interest Rate Parity should hold for all maturities by definition.

It the expected sport rate for a maturity comes true, it does. But not a requirement as covered IRP is.

It simply says that interest rate differential between two countries should equate the countries' inflation rate differentials. Not a requirement again, because inflation rates may deviate from what the int. fisher theory suggests and real F/x rate may change accordingly.
