The Value of Fit Information in Online Retail: Evidence from a Randomized Field Experiment

by Santiago Gallino and Antonio Moreno

Abstract

Online channels generate frictions when selling products with nondigital attributes, such as apparel. Customers may be reluctant to purchase products they have not been able to try on, and those customers who do purchase may return products when they do not fit as expected. Virtual fitting-room technologies provide information about how a product fits a particular customer and promise to mitigate some of the frictions the information gap generates in the retailers’ supply chains. By implementing a series of randomized field experiments, we study the value of virtual fit information in online retail. In our experiments, customers are randomly assigned to a treatment condition where virtual fit information is available or to a control condition where virtual fit information is not available. Our results show that offering virtual fit information increases conversion rates and order value and reduces fulfillment costs arising from returns and home try-on behavior, that is, customers ordering multiple sizes of the same product. We explore mechanisms through which providing virtual fit information helps customers and retailers. We argue that the virtual fitting tool creates spillovers even to products that are not available for virtual try-on, increases loyalty, helps customers better parse their choice sets, and reduces uncertainty by providing size recommendation.

Spoilage, expiration, damage due to employee/customer handling, employee theft, and customer shoplifting usually are not reflected in inventory records. As a result, records often report phantom inventory, i.e., units of good not available for sale. We derive an optimal polynomial-time algorithm for the auditing and replenishment problem with phantom inventory, under the assumption that inventory is known immediately after replenishment. Moreover, we numerically show that a projected service-level threshold policy performs comparably to the optimal.

In 2010, amidst the growth of ecommerce and the emergence of new, purely online, fashion players, Zara launched its first online store, Zara.com. Since then, Zara’s online business had grown at a fast pace. By 2018, 12% of Inditex Group’s total sales came from the online channel. Since the inception of the first online store, Inditex leadership wanted its online and offline businesses to be integrated. However, the increase of online orders challenged some of its operations. Inditex was committed to the vision of becoming fully integrated, fully digital, and fully sustainable by 2020. How could stores continue to be relevant in a world with increasing presence of online touchpoints? What should the store portfolio look like in the medium term? How should Zara use and advance the integrated model going forward? What other challenges and opportunities would arise with the increase of online sales?
