Duchy of Massa and Carrara 1851, thanks to the English engineer and tycoon William Walton. In 1846 the Count Francesco del Medico proposed to the Duke Francis V the construction of the Marble Railway of Carrara, to link the marble quarries to the sea and thereby facilitating the transport of blocks to the areas for sorting, loading, and shipping. This project was also suspended for lack of funds. The Marble Railway was finally built after the Italian unification (1871–1890).

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
