The town is home to many companies of renowned such as the Georges Leroy factory, Graindorge cheese manufacturing which produces Livarot, among others. The commune gave its name to its cheese; Livarot cheese. The La Fermière (CCLF) calvados cider is also produced in the commune.
The etymological explanation of this place name has no unanimity among toponymists:
Albert Dauzat and Charles Rostaing, based on a false attestation of Livaron from 1137 (form and date wrong), described it as "obscure", while evoking a derivision of ivos, an assumed Gallic word designating if, and declaring it unlikely. They perhaps resume in these previous assumptions. In reality, the term *ivos or *īvos is not attested and should include an asterisk.
Ernest Nègre(fr), reasoning from this same erroneous form, considered that it might be from the Germanic name Liubwar, which is followed by the suffix -o /-onem and that the final would be modified by attraction of names in -ot. However, François de Beaurepaire notes that a Germanic name is never used with this suffix.
Dominique Fournier refuted Livaron (cacography attributed to Albert Dauzat, and badly dated) and based it on the actual form Livar(r)ou, stemming from the Chronicle of Robert of Torigni, to advance the hypothesis of a Gallo-Roman person named Libarius followed by the suffix of Gallic origin -avo which explains most of the words ending in -ou of Normandy.
