Hundreds of individuals have impacted economics throughout its vast history. Only a handful of these individuals are household names recognized with economics today. However, many lessor known economists have made lasting impressions, often making attributions to the theories we know today. One of these individuals who influenced economics in this way was Irving Fisher.

Irving Fisher was a very unique and brilliant man. He attended Yale University where he studied mathematics. He later used this background and applied it to economics, earning a PhD in economics, the first from Yale University. His study of mathematics played a crucial role in how his theories evolved. Almost all of his work involves mathematical computations to express the theories he devised. Fisher’s theories were revolutionary in the time period as a result, but his theories and legacy was tarnished due to one public statement in his career. He publicly announced right before the stock market crash of 1929 that the stock market had reached a “permanent plateau” and improvements were imminent. However, we know this never happened and he paid for it in both his career and his financial situation. It wasn’t until years later that people began to look back and realize Irving Fisher still had innovative theories and ideas.

One of these theories that Fisher gave to the world of economics was his theory of interest. His contributions first appeared in The Nature of Capital and Income (1906), next The Rate of Interest (1907) and later the revised version The Theory of Interest (1930). These works drew upon two prior individuals, John Rae and Eugen von Bohm-Bawerk, in developing them. Fisher believed the works of Rae and Bawerk didn’t provide a complete explanation of how the rate of interest is determined. Therefore, Fisher expanded and clarified what both of these economists tried to do. Fisher did this by introducing his two period diagram which showed how interest rates were determined....

...Irving Fisher's Analysis of the Great Depression
My proposition is to take an in depth examination of Irving Fisher's views on the origin of the Great Depression, his debt deflation theory and the policy measures he advocated. Only days prior to the stock market crash, Fisher predicted that the shares were in fact not overvalued and their increases were due to new profit opportunities created by new technological advances and increases in...

...IrvingFisher - His Life
Fisher was born in New York state in 1867. He studied science and philosophy at Yale. Here he had a wide variety of interests. For example, he published poetry and works on astronomy, mechanics, and geometry. Despite all of these interests, Fisher was most interested in mathematics and economics. Yale did not have an Economics Department at the time. Regardless, Fisher continued with his interests...

...BIOGRAPHY 20.1 IrvingFisher (1867 -1947)
IrvingFisher was born at Saugerties, New York, the son of a Congregational minister. As did his father, Fisher studied at Yale. Mathematics was his favorite subject. He won first prize in a math contest even as a freshman; his doctoral dissertation,Mathematical Investigations in the Theory of Value and Prices (1892), was a landmark in the development of mathematical economics....

...The Fisher effect and negative real interest rates by the example of Taiwan
This paper examines the effects of negative real interest rates and talks about developments in Taiwan. For the calculation of the real interest rates the Fisher equation and Fisher effect is examined first. In the end suggestions for the further management of interest rates in Taiwan by the central bank is given.
1. Fisher effect and equation...

...The Fisher Effect and the Quantity Theory of Money

EC-301-1
The Fisher effect and the Fisher equation were made famous by economist IrvingFisher. 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...

Reading notes from Irving Fisher’s The Theory of Interest, 1930
Preface -- It was the misunderstanding of my theory of interest put forward in my 1907
book the Rate of Interest that led me to adopt the catchword “investment opportunity” as
a substitute for the inadequate term “productivity” which had come into general use.
This combined with my early “impatience theory” led to the impatience and opportunity
theory which can be said to be distinct from all other theories...
