We review Irving Fisher's seminal work on UIP and on the closely related equation linking interest rates and inflation. Like Fisher, we find that the failures of UIP are connected to individual episodes in which errors surrounding exchange rate expectations are persistent, but eventually...

100 years ago this year, Irving Fisher adhered to 'price movements being imperfectly foreseen' resulting in short term deviations from UIP, which in the longer term are averaged away. In this paper, we first review Irving Fisher's seminal work on UIP and on the closely related equation linking...

In this paper, we first review Irving Fisher's seminal work on UIP and on the closely related equation linking interest rates and inflation relation. We go on to re-examine the performance of UIP since the advent of floating exchange rates in the 1970s. Like Fisher a century ago, we find that...
