Recherches sur la nature et l'origine de la richesse publique,

First edition in French, published four years after the first edition in English. Lauderdale "has been hailed as a forerunner of Keynes, in as much as he argued that over-saving was a distinct possibility and that public spending was required to offset private thrift if stagnation was to be asserted" (Blaug). In the present work Lauderdale questioned Adam Smith's theory of the relationship between labour and value, maintaining that wealth was a compound of labour, land, and capital, and value was a compound of utility and scarcity. He argued that capital was capable of harnessing productive labour to make profits by meeting market demand, and that such profits resulted only when there were no legislative restraints on commerce and no burdens, such as Pitt's sinking fund to redeem the national debt. "Lauderdale's importance in the history of economics lies, not in his conclusions, but in the fact that he was the first in England to consider systematically the fundamental conceptions on which the science is based. In this respect alone he is in advance of Adam Smith" (Palgrave II, p. 574).
