Abstract: We study a buyer's sourcing strategy along two dimensions: the supply base design and the pricing mechanism, considering supplier competition and cost-reduction effort. The supply base design concerns the number of suppliers (one or two) included in the supply base and the capacity to be invested in each supplier. The pricing mechanism determines the timing of the price decisions, with the buyer making price commitments before suppliers exert cost-reduction efforts that may be renegotiated afterward. We find that symmetric capacity investment in suppliers and low price commitments (more likely to be renegotiated) are effective at fostering supplier competition, whereas asymmetric investment and high price commitments (less likely to be renegotiated) are better at motivating supplier effort. A complementary relationship exists between the supply base design and pricing mechanism: A more symmetric supply base should be combined with lower price commitments, leading to more renegotiation opportunities. This results in three possible sourcing structures: sole sourcing (investing capacity in a single supplier and forming price with ex ante commitments), symmetric dual sourcing (investing equal capacity in both suppliers and forming price with ex post negotiations), and asymmetric dual sourcing (investing positive but unequal capacities in two (ex ante identical) suppliers and forming price using both ex ante commitments and ex post (re)negotiations). We characterize the conditions for each structure and identify a strategic role of capacity investment. This paper was accepted by Martin Lariviere, operations management.
