Proceedings of 8th Annual London Business Research Conference Imperial College, London, UK, 8 - 9 July, 2013, ISBN: 978-1-922069-28-3 On Competitive and Comparative Advantage Bernard C. Beaudreau The field of international business/economics is largely dualistic in nature. On the one hand is the economics literature which has, for the most part, focused on the notion of comparative advantage (technology, factor proportions) while on the other hand is the business literature which has focused on competitive advantage. Over the years, there have been a few attempts at integrating the two (Neary 2004). This paper presents an alternative approach based on global value chain/supply chain analysis and the concept of vertical comparative advantage (Beaudreau 2011). Accordingly, competitive and comparative advantage are compared and contrasted at the individual \link level.
