The Fisher effect and the Fisher equation were made famous by economist Irving Fisher. He created his equation by rearranging the equation for real interest rate, which is (r = i - π). Real interest rate equals the nominal interest rate plus inflation. This is a very basic equation. Fisher manipulated it to solve for i, in order to understand the effect that inflation has on nominal interest rate. The famous equation is i = r + π, nominal interest rate equals real interest rate plus inflation. This is basically saying that the nominal interest rate can be changed by a change in either the real interest rate or inflation. The Fisher effect is the …show more content…

However, the two variables seem to level out and return to their “natural” state in the long run. When the economy is doing poorly, businesses are less likely to borrow money. In order to counteract this, the Fed will keep the interest rate low to encourage businesses to invest and hopefully jumpstart the economy. (WorldBank) The graph above focuses on the relationship between the inflation rate and the nominal interest rate from 1990 to 2010. There seems to be supporting evidence of the fisher effect in this graph excluding 1993 to 1999. Many economic experts have tried to offer possible explanations for the relatively low inflation rates during this time period. Robert Rich and Donald Rissmiller have attributed it to two main factors. The first is conventional economic forces. There were multiple positive supply shocks in the U.S. economy throughout this decade. Commodity and energy prices saw a significant decrease and the U.S. dollar appreciated internationally at many times. The second explanation they offer is the advances in productivity and increased competition among producers. With the new technological advances, new producers were able to into new markets and productivity rapidly increased. The Federal Reserve increased the nominal interest rate in order to help control the economic boom; however the inflation rate was low due to the combination of certain factors. The Fisher effect does not
