E-Tailing in the Age of Platforms

Consumer Data Allows Retailers to Understand the Value of Multi-Sided Platforms (MSPs)

For centuries, retailers have joined one another in markets, malls, or other common locations to sell products to consumers. And for as long as this practice has been in place, there are questions that the retailers simply could not answer as they did not have access to consumer’s purchase behavior at other competing retailers.

Multi-side platforms (MSPs) allow us to answer questions related to consumer behavior across retailers. MSPs are digital platforms that connect multiple groups of stakeholders, such as consumers and retailers, and facilitate direct interactions among them.

Spiegel Research Center conducted a study on MSPs using the data provided by ShopRunner, a U.S.-based MSP. The study analyzes consumer behavior to ultimately provide retailers answers to the questions they’ve never been able to answer before.


Questions we address:

As we performed our analysis on the data, we honed in on these three questions:

  1. Are MSPs beneficial to both consumers and retailers, and, if so, how and why?
  2. Are all retailers impacted the same way by being in an MSP?
  3. Do retailers benefit, or are they harmed from being in an MSP with a direct competitor?

About the Research


The data for this study is provided by ShopRunner, a U.S.-based MSP, launched in 2010. Since then it has hosted more than 10 million consumers and worked with more than 250 retailers including Neiman Marcus, Ann Taylor, and Chico’s.

In total, the retailers on the MSP represent 11 different categories, from sports and electronics to jewelry and toys.


The Network Effect in the MSPs

MSPs are beneficial for both retailers and consumers because of the network that exists on the platform.

Benefit for Retailers

The fundamental principle behind network theory states that there is an exponential value added whenever there is an addition to a network. When a consumer buys a product from a stand-alone retailer, that adds value to the retailer, but it’s not an exponential increase. When a retailer joins ShopRunner, though, not only do their customers benefit from the network benefits, but the retailers also gain access to all the other network’s customers who have joined and/or purchased from other participating retailers. That is an exponential increase in value.

Benefit for Consumers

ShopRunner offers great benefits to consumers like free shipping and two-day delivery, but the reality is those deals can also be offered by individual retailers. The way ShopRunner delivers value to consumers is that they provide an easy-to-access subset of retailers where consumers know shipping will be fast and free with a standard checkout process.
