The Sindicato Vinícola del Baix Priorat was founded in1913, and the Sindicato Agrícola was founded in 1919. Both of them prepared carefully the wine of the members of these unions. In1936 the two unions joined into the Cooperativa Agrícola de Falset, which is now occupied in preparing and comercializing the wines (denominación de origen de Tarragona, subregion of Falset) and the almonds and hazels.

Some people are occupied in the industry: constructions, textiles, cratsmanship, etc, and finally in services such as trade and tourism.

The good greographical position and the net of comunications cause that one part of the avtive population works in other villages of the county, or in the next counties (Baix Camp and Ribera d'Ebre).
