Principles of Economics, Book 2: Some Fundamental Notions

The book that invented modern economics. Alfred Marshall's masterwork, first published in 1890, gave the world the analytical tools we now take for granted: supply and demand, marginal utility, elasticity, consumer and producer surplus. Before Marshall, economics was a diffuse field; after him, it was a science. He spent nearly a decade crafting this text, and his careful synthesis of earlier thinkers with his own original insights created the neoclassical framework that still underlies economic thought today. This second volume explores fundamental notions: how marginal analysis shapes individual choice, how costs determine supply, and how markets find equilibrium. Marshall's genius lay in making invisible forces visible, showing readers the hidden architecture behind prices, trade, and wealth.
