Marketplace, reseller, or web-store channel: The impact of return policy and cross-channel spillover from marketplace to web-store

With the advent of e-commerce, new platform sales have been created in the online retailing industry, and choosing the best platform has become a challenge for manufacturers. For instance, marketplace and web-store are two e-channels for selling goods directly to end customers. In the marketplace, manufacturers sell their products directly to online customers through e-tailers' platforms and share revenue with e-tailers. In the web-store channel, manufacturers sell their products directly to end customers through their platforms and do not need to e-tailers' platforms. However, some manufacturers and e-tailers continue with reseller channel yet. Reseller channel is another conventional channel in which manufacturers distribute their products to e-tailers, then e-tailers choose retail prices and sell them to consumers. Therefore, with these three different channels, the key question is when and under what conditions manufacturers can choose marketplace or reseller channel in addition to their web-store channels to grow their market share. In this paper, we analyze these three different e-channels and the conditions that manufacturers adopt the marketplace or reseller channel. For this purpose, we consider a model with two manufacturers and one e-tailer in which the manufacturers have their web-store channels, and they are willing to adopt another channelـ reseller or marketplace. The manufacturers offer a return policy in their web-store channels as a competitive strategy for attracting more customers. We find that offering return policy in web-store channels has no effect on the choice between the marketplace and reseller channel, but it has an impact on the amount of manufacturers' profits in each channel. Also, we demonstrate that regardless of offering return policy, as the coefficient of cross-channel effect increases, the manufacturers' profits, whether they choose reseller channel or marketplace channel, increase. But, as the coefficient of cross-channel effect increases, the e-tailer's profit increases when both manufacturers choose reseller channel, otherwise decreases. If manufacturers offer a return policy, the e-tailer's profit is highest when both manufacturers choose reseller channel, and if they do not offer a return policy, the e-tailer's profit is highest when both manufacturers choose marketplace channel.
