This research was conducted in collaboration with the University of Tsukuba, with support from "mercari R4D," the research and development organization of Mercari.

KDD is one of the most prestigious international conferences in the field of data mining, held annually by researchers from around the world. This year, it was held in Barcelona, Spain, from August 25 to 29, 2024.

Key points of presentation

Strategic Coupon Allocation for Increasing Providers' Sales Experiences in Two-sided Marketplaces

• In this presentation, we proposed a coupon distribution strategy aimed at providing as many sellers as possible the experience of selling their products.
• Through the satisfaction brought about by the selling experience, users are more likely to continue listing their items actively, which is expected to enhance the attractiveness of the platform as well as the quantity and diversity of the products listed.

Background

In a C2C marketplace like Mercari, where the platform provider does not have a direct supply chain, it is necessary to encourage individual sellers' voluntary listing activities to increase the quantity and variety of listed items. Since listing items involves certain efforts such as selecting products, taking photos, and packaging after sale, strong motivation is essential for sellers to act actively. Although the factors that influence listing motivation vary by individual, we believe that the most fundamental and important experience is the "selling experience" (the experience of having products sold). Therefore, it is crucial to provide as many users as possible with the selling experience.

However, in two-sided markets like Mercari, there is a risk that transactions might be skewed towards a certain group of users without appropriate intervention by the platform provider. To address this, our Data Science team aimed to use coupons, one of the most commonly used marketing tools, to alleviate the concentration of transactions and provide more sellers with the selling experience.

Summary of paper

In this paper, we propose a method for optimizing coupon distribution strategies with the number of users having selling experiences as the KPI. Generally, to optimize coupon distribution for a specific KPI, targeted interventions for the users are necessary. In this paper, we propose an efficient coupon distribution strategy using Uplift modeling and mathematical optimization.

By utilizing the proposed method, we confirmed with Mercari's actual data that more sellers could have selling experiences compared to conventional methods. The implementation of this method is expected to enhance the satisfaction of many sellers and promote their voluntary listing activities.
