A history lesson on the man behind the "Fisher effect"
"Fisher developed revolutionary insights into financial theory that are still invoked today. He explained that the market interest rate coincides with the human tendency to discount an uncertain future when compared with the more pressing present. He argued that we distribute our present and expected future wealth over the consumption decisions we make now and in the future. In doing so, he anticipated the life-cycle hypothesis that would demonstrate, half a century later, why we save and how we consume."
