摘要：
Customers often evaluate products at brick-and-mortar stores to identify their “best fit” product but buy it for a lower price at a competing online retailer. We begin with analyzing this free-riding behavior by customers (referred to as “showrooming”) and show that this is detrimental to the profits of the brick-and-mortar stores. Next, we examine price matching as a short-term strategy to counter showrooming. Since customers purchase from the store at lower than store posted price when they ask for price-matching, one would expect the price matching strategy to be less effective as the fraction of customers who seek the matching increases. However, our results show that with an increase in the fraction of customers who seek price matching, the store’s profits initially decrease and then increase. We then study exclusivity of product assortments as a long-term strategy to counter showrooming. This strategy can be implemented in two different ways. One, by arranging for exclusivity of known brands (e.g. Macy’s has such an arrangement with Tommy Hilfiger), or, two, through creation of store brands at the brick-and-mortar store (T.J.Maxx uses a large number of store brands). Our analysis suggests that implementing exclusivity through store brands is better than exclusivity through known brands when the product category has few digital attributes. We estimate the treatment effect of store openings on the online purchase behavior of its existing customers. We find that retailer’s store openings resulted in increase in the online purchases from its existing customers. We propose two mechanisms that could explain these results: (1) store engagement effect-higher customers’ engagement with the retailer due to higher store interactions, and (2) store return effect-reduced risk of online purchase due to the low cost option of store returns. We provide direct empirical evidence of these mechanisms on our field data. We further show that these effects are caused by reduction in customers’ distances from the retailer’s store due to the store openings. Many retailers and manufacturers adopt the practice of accepting product returns from consumers (via money-back guarantee) and retailers (via full-credit returns policy) respectively. While the extant literature focuses on either the manufacturer’s or retailer’s returns policy, this paper investigates both returns policies and finds that the manufacturer’s returns policy can actually induce the retailer’s returns policy by transferring consumer returns from the retailer to the manufacturer. Consequently, the manufacturer’s returns policy hurts the manufacturer when the manufacturer sells through non-competing retailers. Nonetheless, we find that the manufacturer is not destined to be hurt by accepting product returns when selling to competing retailers. More interestingly, this result holds when the retailers face a certain demand before sales, which is in sharp contrast to the extant literature. In a similar vein, product returns can benefit rather than hurt the distribution channel as a whole when the manufacturer sells through competing retailers.
