Based on 2.91 million user sessions, this study analyzes the effect of user-generated social-shopping features on micro-conversions. In the authors’ specific case of a social shopping community (SSC), the authors define a micro-conversion as a visit to a product-detail page. These visits are a requisite for visits to participating online-shops (click-out) for which the operator of a SSC receive...

We employ a two-dimensional model of customer heterogeneity — specifically, we assume that customers...

Crowdsourced wireless community network enables individual users to share their private Wi-Fi access points (APs) with each other, hence can achieve a large Wi-Fi coverage with a small deployment cost via crowdsourcing. This paper presents a novel contract-based incentive framework to incentivize such a Wi-Fi network crowdsourcing under incomplete information (where each user has certain privat...
