Carrara Carrara Carrara () is a city and "comune" in Tuscany, in central Italy, of the province of Massa and Carrara, and notable for the white or blue-grey marble quarried there. It is on the Carrione River, some west-northwest of Florence. Its motto is "Fortitudo mea in rota" (Latin: "My strength is in the wheel"). There were known settlements in the area as early as the 9th century BC, when the Apuan Ligures lived in the region. The current town originated from the borough built to house workers in the marble quarries created by the Romans after their conquest of Liguria
Economic region of production Economic region of production In economics, the economic region of production is an offshoot of the theory of production function with two variables. It is a cost-oriented theory which defines the region in which the optimal factor combination will lie. It serves as a map of the region of optimal production. Production lines Q1 and Q2 are the isoquants, depicting the technically efficient factor combinations at different levels of production. The ridge lines A and B demarcate the technically efficient region of production. Above the line OA and below the line OB slope of the isoquants is positive which means
