Considered one of the founders of the English classical school of political economy, along with Adam Smith and Thomas Malthus, David Ricardo exerted a significant influence on both neoclassical economists and Marxist economists, highlighting his importance to the development of economic science. In his work "Principles of Political Economy and Taxation," Ricardo discusses his reflections on various points of political economy in light of the ideas and contributions of figures he openly admired, such as Adam Smith, Jean-Baptiste Say, Thomas Malthus, and others. Ricardo elaborates on the concept of value according to Smith's reflections, explicitly presenting some of his objections to the topic. He also presents his most notable contribution to economic thought, the theory of comparative advantage, in addition to taxation and other important reflections that make this work one of the cornerstones of contemporary economic thought.
