Fisher Effect

Fisher Effect -- this effect is an economic theory (which is created by economist Irving Fisher) that describes the relationship between inflation and both real and nominal interest rates. The Fisher Effect states that "the real interest rate = the nominal interest rate - the expected inflation rate". (Therefore, real interest rates fall as inflation increases, of course, unless nominal rates increase at the same rate as inflation.)
