His Ragionamento sopra i bilanci economici delle nazioni (1759), in which he maintained that what is termed the balance of trade between two nations is no criterion of the prosperity of either, since both may be gainers by their reciprocal transactions. And his Sul libero commercio dei grani (1771), in which he argues that free trade in grain is not always advisable.
