Investors, for example, are not all alike—each has a unique and subjective combination of time horizon and risk tolerance. In contrast, mainstream and Keynesian economics ignore differences among individual agents by assuming, for simplicity and analytical convenience, that everyone is identical, or that differences among market participants do not matter and can be ignored.
