Traditionally, the major sources of income have always been farming and animal husbandry. But in the 1950s, these lost importance. Starting in the 16th Century, the income from seasonal migration (especially chimney sweep in Lombardy and Piedmont) were added to the local economy. Between 1631-1847 the people of Rasa (along with Ronco, Losone and Terre di Pedemonte) possessed the monopoly for loading operations at the Custom House of Livorno. In the second half of the 19th Century there was a strong emigration overseas (America, Australia). The local industrial production; watch factory, the quarry, the carpentry factory and the Peduli factory (cloth shoes with hemp soles from the early 20th century to 1962) came to a halt in the 1960s.
