Herbert A. Simon's chapter explores the interplay between economics and psychology, questioning whether recent developments in psychology can be fruitfully applied to economics and vice versa. Simon argues that economics, traditionally focused on normative macroeconomics and deductive theory, has been less interested in descriptive microeconomics, which aims to understand individual economic behavior. He suggests that while classical economic theory, assuming rationality and perfect competition, is useful in certain areas, it fails to address central issues of conflict and dynamics. Simon uses a metaphor of molasses in an irregular bowl to illustrate the limitations of classical economic models, emphasizing the need for more empirical and descriptive approaches in economics.Herbert A.
