"The Theory of Political Economy" (by William Stanley Jevons)

"The Theory of Political Economy" by William Stanley Jevons is a foundational work that analyzes how economic systems function, particularly focusing on the determination of prices and the distribution of resources. Jevons emphasizes the role of utility—how useful goods are to people—and how individual choices driven by maximizing satisfaction influence market outcomes. He introduces the concept of marginal utility, showing that prices are set based on the additional satisfaction gained from consuming one more unit of a good. Overall, the book explains economic behavior through a logical, mathematical approach, helping to clarify how markets coordinate supply and demand.
