In 1765 he founded the first economics periodical to be published in France, Éphémérides du citoyen, and was at first an opponent of the physiocrats. In 1766, however, he became a proponent of physiocracy. He died in Paris in 1792.
One of Baudeau's influential works, Idées d'un citoyen sur l'administration des finances du Roi, was critical of the commission established in 1764 by Clément Charles François de Laverdy for the purpose of drafting new laws on vagabonds, beggars, and the central distribution of alms. Baudeau argued that the governmental provision of alms to the poor was a more important goal than the passing of laws prohibiting poverty.
In 1768, Baudeau was recruited by Ignacy Jakub Massalski, the Bishop of Vilnius, in order to bring physiocratic ideas to Poland. The main focus of his work there had to do with facilitating exports of Polish grain to France.
Baudeau died in 1792 in Paris.
