This paper analyses the sources of buyer power and its effect on sellers' investment in quality improvements. In our model retailers make take-it-or-leave-it offers to a producer and each of them in equilibrium obtains its marginal contribution to total profits (gross of sunk costs). In turn, the individual marginal contribution depends on the rivalry between retailers in the bargaining process. Rivalry increases when retailers are less differentiated and when decreasing returns to scale in production are larger. The allocation of total surplus affects the incentives of the producer to invest in product quality, an instance of the hold-up problem. An increase in buyer power not only makes the supplier and consumers worse off, but it may even harm retailers, that obtain a larger share of a smaller surplus.

Abstract

This paper analyses the sources of buyer power and its effect on sellers' investment in quality improvements. In our model retailers make take-it-or-leave-it offers to a producer and each of them in equilibrium obtains its marginal contribution to total profits (gross of sunk costs). In turn, the individual marginal contribution depends on the rivalry between retailers in the bargaining process. Rivalry increases when retailers are less differentiated and when decreasing returns to scale in production are larger. The allocation of total surplus affects the incentives of the producer to invest in product quality, an instance of the hold-up problem. An increase in buyer power not only makes the supplier and consumers worse off, but it may even harm retailers, that obtain a larger share of a smaller surplus.
