Books And Author

Alfred Marshall authored Principles of Economics (first published in 1890), a landmark text that formalized many microeconomic ideas.
By contrast, Adam Smith wrote The Wealth of Nations (1776), and Lionel Robbins wrote An Essay on the Nature and Significance of Economic Science (1932).
Marshall's book introduced and popularized core concepts such as elasticity of demand, consumer surplus, and partial equilibrium analysis, shaping modern microeconomics.
