The economics of partnership sourcing versus adversarial competition: a critique

Abstract

In the strategic procurement management literature two general forms of purchasing arrangement feature—‘partnership sourcing’ and ‘competition’. Usually partnership sourcing is said to be superior because it leads to long-term collaboration based on trust between buyer and supplier. One product is a reduction of the supplier base with firms perhaps relying on a single source of supply or a small number of preferred suppliers. The paper reconsiders procurement methods in terms of a continuum using the economics of transaction costs. The paper then illustrates the economic issues discussed by considering procurement in the defence sector. Defence is taken as an example of public procurement with experience and opportunities for competition, partnership sourcing and long-term buyer-supplier relationships. The paper concludes that the case for partnership sourcing over competition is not clear cut.
