Irving Fisher Biography

Irving Fisher was an American economist whose work laid the foundation for many modern economic theories. He contributed significantly to utility theory, general equilibrium, and pioneered the rigorous study of intertemporal choice in markets, leading to his theory of capital and interest rates. His research on the quantity theory of money is regarded as the inception of monetarism. Although his reputation was damaged by his stock market predictions, his later theories on debt deflation and his work on capital and interest remain influential.
