This volume gathers the Complete Works of David Ricardo , one of the towering figures of classical economics. It includes his seminal treatise On the Principles of Political Economy and Taxation , where Ricardo lays out his theories on value, rent, and distribution, and introduces the concept of comparative advantage , a fundamental principle of modern trade theory. Also featured is The High Price of Bullion , where Ricardo demonstrates the depreciation of paper currency, and Essay on the Influence of a Low Price of Corn , which examines the intricate relationships between agricultural prices and capital returns. Together, these essays present a powerful critique of early 19th-century monetary and fiscal policies. The volume concludes with Ricardo’s letters to Thomas Malthus , a vivid intellectual exchange that highlights both the harmony and the tension between two of the most brilliant minds of their time. These letters reveal a personal dimension to economic theory—one of deep curiosity, mutual respect, and rigorous debate. This definitive edition is an essential resource for students, historians, and anyone interested in the roots of economic science. With clear, systematic exposition and powerful reasoning, Ricardo’s works continue to illuminate the economic challenges of our world.
