Abstract: The diversion of manufacturers’ branded products outside the authorized channel leads to the emergence of gray markets (GMs), which is legal under the doctrine of first sale. Product diversion to GMs can negatively affect manufacturers’ brand reputation. In this study, we analyze a manufacturer’s strategic channel choice decision and its implications for social welfare in the presence of GMs and strategic consumers. We present scenarios in which the presence of GMs can either have a positive or negative impact on the manufacturer and the supply chain. Our findings indicate that the manufacturer and the supply chain become worse off due to product diversion to GMs under lower channel differentiation and high penalty cost for the loss of brand reputation due to product diversion. This effect is more severe for a decentralized supply chain, where product diversion does not directly affect the retailer’s profitability due to the erosion of brand reputation. In such scenarios, we suggest that manufacturers should follow a brand-protection strategy to curb product diversion to GMs. However, manufacturers selling product categories with low brand equity can follow a market-expansion strategy. In such cases, the presence of GMs provides an alternative channel to expand sales by capturing untapped consumer segments without incurring additional market search or advertising costs. This strategy also facilitates indirect price discrimination among consumers. We find that social welfare is higher when channel differentiation is low under a decentralized supply chain. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
