David Ricardo is best known today for his pioneering articulation of the theory of comparative advantage-the idea that trade is most mutually beneficial when parties specialize according to there relative opportunity costs and then trade. But comparative advantage is only one part of Ricardo's extensive analyses of the determinants of rents and the distribution of income. He developed his ideas in the context of government restrictions on trade, first from blockades during the Napoleonic Wars and the the Corn Laws that Parliament passed to restrict imports of grains into the UK.In this book,David Ricardo illustrates all economical problems covering value,rent, natural and market price,wages, profits, foreign trade,taxes, rates and so on and so forth.

David Ricardo (18 April 1772 – 11 September 1823) was a British political economist. He was one of the most influential of the classical economists, along with Thomas Malthus, Adam Smith, and James Mill. Perhaps his most important legacy is his theory of comparative advantage, which suggests that a nation should concentrate its resources solely in industries where it is most internationally competitive and trade with other countries to obtain products no longer produced nationally. In essence, Ricardo promoted the idea of extreme industry specialization by nations, to the point of dismantling internationally competitive and otherwise profitable industries. Ricardo took as a given the existence of a national industry policy aimed at promoting some industries to the detriment of others. F
