"Supply and Demand" by Hubert D. Henderson serves as a foundational guide that conveys general principles of economic thought to both the ordinary reader and the uninitiated student. Rather than aiming for original contributions to knowledge, the work focuses on expounding the most significant elements of economic method to intelligent readers unfamiliar with the subject, while anxiously avoiding obscurity. The book comprehensively covers essential topics ranging from the general laws of supply and demand, utility, and the margin of consumption, to the complexities of land, labour, capital, and risk-bearing enterprise.
