Malthus has become widely known for his theories about population and its increase or decrease in response to various factors.

The The Fable of The Bees: or, Private Vices, Publick Benefits by Bernard Mandeville, of 1714, is credited by Keynes as the most popular exposition of underconsumptionism of its time, but it caused such an uproar, being seen as an attack against Christian virtues, specifically attacking temperance, that underconsumptionism was not mentioned in " respectable circles " for another century, until it was raised in the later Malthus.

Many other authors were influenced by the book and used it as a starting point in their own work, including Jean-Baptiste Say, David Ricardo, Thomas Malthus and, later, Ludwig von Mises.

Moreover, Smith's allowance for wage increases in the short and intermediate term from capital accumulation and invention added a realism missed later by Malthus, Ricardo, and Marx in their propounding a rigid subsistence-wage theory of labour supply.
