Comparative advantage in de-globalisation: Brexit, America First and Africa's continental free trade area.

This paper aims to examine the relevance of the theory of comparative advantage in the present realities of a world undergoing de-globalisation, that is, a retreat from closer integration.,This paper presents eight arguments that analyse the theory as posited by Adam Smith and David Ricardo and that theory remains the underpinnings for trade liberalisation as regulated by the World Trade Organisation (WTO).,The arguments do not contend with the role and achievements of the WTO in the era of globalisation. Rather, these call for an acknowledgement of the changing realities of countries in the face of changes in the political, economic and legal landscapes, across the globe.,This is an original submission by the author.
