John Medaille asked: "Do I take it then that we have reached agreement at least on the third point, that Ricardo assumed that capital is confined to national boundaries?" No, Ricardo did not assume that capitals are always confined to national boundaries. On the possibility of capital mobility between countries and its determinants in Ricardo's analyses, see e.g., Works 1: 136-7, 247-8, 2:452, and 3: 274. James Ahiakpor
