What’s the Fisher effect?

The Fisher effect is a theory that states that when inflation rises, interest rates will also rise by the same amount. Irving Fisher, an economist, developed this theory and became well-known for it. The International Fisher effect allows economists to compare the currencies of two countries based on interest rates. However, some economists do not believe in the relevance of this theory.

Interest rates and inflation are objects of financial fascination around the world. The Fisher effect is a theory about the relationship between the two, basically stating that when one rises, so does the other. The theory refers exclusively to domestic rates, but there is a related theory about the relationship of interest and inflation on an international scale. This hypothesis has been used by specialists in economics for many years, but there are still some who do not believe in its relevance.

Irving Fisher was an economist in the United States who graduated from Yale University in 1888 and died in 1947 at age 80. He became one of the best known economic minds of his time due to his theory of the Fisher effect and his theory of debt deflation. His neoclassical economic ideas were taught in economics classes around the world.

Fisher’s famous hypothesis, the Fisher effect, deals directly with the relationship between interest rates and inflation. In Fisher’s eyes, the two are bound by a variety of economic demands. The relationship is so strong that if inflation rises, the interest rate will rise by the same amount.

The Fisher effect is often used by companies to understand the real or nominal interest rate. An example of this would be to consider a country’s rising inflation rate. If a country’s inflation rate increases by 1%, the Fisher effect states that the interest rate will also increase by 1%.

A slightly improved version of the Fisher effect allows economists to compare the currencies of two countries based on interest rates. The International Fisher effect states that the difference between the interest rates of two countries will directly affect the exchange rate between those two currencies. In this hypothesis, the value of the currency with the lower nominal interest rate will increase due to the higher rate in the other country.

The Fisher effect remains a theory and not a proven fact. Many economists completely denounce Fisher’s thoughts on the relationship between interest rates and inflation. Many economists claim that interest rates and inflation are independent of each other and totally unpredictable due to the incredible amount of factors involved, such as the labor market, currency exchange, imports and exports. This too is a theory and, like Fisher’s theory, is an attempt to make predictions about financial fluctuation.
