Reasons for the Demise of Interest: Savings Glut and Secular Stagnation or Central Bank Policy?
Abstract: This article compares the Keynesian, neoclassical and Austrian explanations for low interest rates and sluggish growth. From a Keynesian and neoclassical perspective, low interest rates are attributed to aging societies, which save more for the future (global savings glut). Low growth is linked to slowing population growth and a declining marginal efficiency of investment as well as to declining fixed capital investment due to digitalization (secular stagnation).
