REPRINT 2007. Hardbound. Octavo. xxiv, 251. Oxford, Clarendon 1887. The letters in this collection were written between 1810 and 1823, the last ones dating only a few days before Ricardo's death. The letters are mostly devoted to discussing the many questions in political economy on which the two authors disagreed. Malthus' letters to Ricardo are lost, so we have only Ricardo's response to Malthus. The two men were personal friends, and were often in each other's company, but on economic themes they differed widely. The book is well edited and it contains much information, both in the text and in the notes, about Ricardo and Malthus themselves, and also about other political economists of the period.
