Title：Impact of Unreliable Supplier On the Supply Chain

Abstract: A firm often has multiple sourcing options for its product. Some suppliers may have longer lead time but offer cheaper prices whereas reliable suppliers with quick response may have higher prices. Purchasing from a cheaper, less reliable supplier can help a firm lower its inventory cost, but will also expose itself to potential risks. This paper analyzes a supply chain in which the retailer can source from a cheaper, less reliable supplier with long lead time and/or a reliable supplier with quick response. The retailer also has to make demand-generating marketing investment before the selling season. Our analysis shows that if the unreliable supplier's reliability is low, the reliable supplier will charge a low wholesale price, otherwise it will choose a high wholesale price. As the unreliable supplier's reliability improves, the retailer is inclined to increase its marketing investment, but there is a drop at some critical threshold. Interestingly, the existence of the unreliable supplier can lead to a win-win outcome for the reliable supplier and the retailer. The unreliable supplier's reliability has non-monotonic effects on the equilibrium profits of the reliable supplier and the retailer. We show that the main insights hold when the consumer's product valuations are heterogeneous and when the retailer can set its retail price after learning whether the unreliable supplier experiences disruption. Moreover, the reliable supplier makes a higher profit when the retailer has to decide its retail price ex ante (before supply risks are resolved) than ex post, whereas the retailer is better off it can set its price after supply risks are resolved.
