The Fisher effect is defined as the relationship between real rates and _____ 

The Fisher equation is a concept in economics that determines the relationship between nominal and real interest rates under the effect of the inflation. The equation states that the nominal interest rate is equal to the sum of the real interest rate and inflation. According to Fisher equation : R Nominal = R Real + R Inflation Real Interest Rates: A real interest rate is the interest rate that takes inflation into account. This means it adjusts for inflation and gives the real rate of a bond or loan. Nominal Interest Rates: A nominal interest rate refers to the interest rate before taking inflation into account.  It is the interest rate quoted on bonds and loans.
