摘要：Many e-commerce platforms have launched reviewer incentive programs, in which the platforms send free samples to experienced reviewers in exchange for feedback on the samples. This study focuses on an unexplored aspect of this practice: the impact of free samples on reviewers' ratings of subsequently purchased products (i.e., regular ratings). We theorize that free samples can increase regular ratings through two mechanisms: uncertainty reduction and reciprocity. We collect observational data ...

摘要：Although some scholars raise alarm about societal harm emerging from Big Data practices, critical social theory (CST) Information Systems research on the structures and dynamics driving Big Data practices is rare. In this research commentary, we interrogate how tech firms use social practices and platform design to strategically manipulate individuals into accepting datafication and data assetization that accrue positive data network effects for themselves and mostly negative data network effe...

摘要：We consider a marketplace where a recommender system provider (the firm) offers incentives to acquire prospective consumers by leveraging information that a market intermediary collects about these consumers. We investigate a model of consumer acquisition that incorporates several factors affecting acquisition decisions, including the value that a consumer contributes to the recommender system, the cost of participation to the consumer (e.g., privacy loss), and the value that a consumer can de...

摘要：Match formation is challenging in online matching platforms where suppliers are subject to dynamic capacity constraints. We provide a theoretical foundation for understanding how online matching platforms support the transmission and triangulation of multisource information for consumers to infer provider service quality and dynamic capacity states, and achieve desirable matching outcomes. Situating this study in the context of an online health consultation community (OHCC) and drawing upon si...

摘要：We consider districts that invest in critical IT infrastructure, which spill over to other districts. IT infrastructure is considered critical if its disruption can cause significant damage to security, the economy, public health, or safety. Districts choose whether to participate in a coalition noncooperatively, and the coalition subsequently makes resource investment decisions cooperatively. Districts inside the coalition have superior interoperability in the spillovers relative to outside d...

摘要：We develop a framework to measure the value of free goods and services available on the internet. The conventional method of measuring consumer surplus based on monetary expenditures is ineffective because these goods' prices are predominantly zero. Our proposed method addresses this challenge by quantifying the economic value of the time that consumers devote to consuming these free goods. Using data on consumers' time and monetary expenditures, we calibrate an economic model of the allocatio...

摘要：Product shipping is an indispensable but costly operation in online retailing. Although several initiatives are underway to reduce the shipping cost, an important innovation is the membership-based free shipping (MFS) program, in which a retail platform that allows third-party sellers to sell their products for a commission bears the shipping costs for purchases made by members who have paid an up-front fee. We identify several strategic impacts of MFS programs that are the key drivers to thei...

摘要：Information systems (IS) scholars have pursued phenomenon-specific research to meaningfully engage with and contribute to addressing societal grand challenges (GCs). Although such efforts are invaluable, a broader framework that identifies generalized organizing problems in tackling GCs and reveals promising pathways for digital technologies to add value in addressing them could help establish an agenda for impactful IS research. In this article, we offer such a framework by drawing on Ostrom'...

摘要：Review spammers can harm the trustworthy environment of online platforms by purposefully posting unauthentic ratings and comments for products or online merchants, with the aim of gaining improper benefits. Although many methods have been proposed to resolve the spammer detection problem, several challenges, such as collusion recognition, label scarcity, and biased distributions, are still persistent and call for further investigation. Building on prevalent collusive spamming behaviors and the...
