Research shows that consuming ratings influences purchase decisions in e-commerce and also has modest effects on belief in news articles on social media. We find that the act of producing ratings reduces belief in news articles on social media and induces social media users to think more critically. We propose this intervention as a method to encou...

In contrast to industries of other types of information goods, the video game industry still has a sizable secondhand market for games. This is particularly notable because some of the major gaming-console companies (e.g., Sony and Microsoft) actually possess the ability to annihilate the secondhand market altogether; it appears that those companie...

Background: Public health campaigns to curb the spread of COVID-19 are important in reducing its spread, but backlash to traditional information-based campaigns has been unexpectedly extreme. Objective: To understand if customizing public service announcements (PSAs) providing health guidelines to match individuals' identities increases complian...

BACKGROUND Public health campaigns aimed at curbing the spread of COVID-19 are important in reducing disease transmission, but traditional information-based campaigns have received unexpectedly extreme backlash.

Disinformation on social media—commonly called “fake news”—has become a major concern around the world, and many fact-checking initiatives have been launched in response. However, if the presentation format of fact-checked results is not persuasive, fact-checking may not be effective. For instance, Facebook tested the idea of flagging dubious artic...

Objective: The objective was to understand how people respond to COVID-19 screening chatbots. Materials and Methods: We conducted an online experiment with 371 participants who viewed a COVID-19 screening session between a hotline agent (chatbot or human) and a user with mild or severe symptoms. Results: The primary factor driving user response...

As a remedy against fake news on social media, we examine the effectiveness of three different mechanisms for source ratings that can be applied to articles when they are initially published: expert rating (where expert reviewers fact-check articles, which are aggregated to provide a source rating), user article rating (where users rate articles, w...

In this paper, we study the economic impact of piracy on the supply chain of information goods. When information goods are sold to consumers via a retailer, in certain situations, a moderate level of piracy seems to have a surprising positive impact on the profits of the manufacturer and the retailer while, at the same time, enhancing consumer welf...

Since the time the industry for e-books transitioned from the wholesale to the agency model, several interesting observations have been made. For instance, despite its revenue-sharing approach that is supposed to be effective in addressing channel coordination issues present in wholesaling, the agency model has curiously led to higher prices and le...

Controlling digital piracy has remained a top priority for manufacturers of information goods, as well as for many governments around the world. Among the many forms taken by digital piracy, we focus on an increasingly common one-namely, online piracy-that is facilitated by torrent sites and cyberlockers who bring together consumers of pirated cont...

We study the economic impact of piracy on the supply chain of information goods. When information goods are sold to consumers via a retailer, in certain situations, a moderate dose of piracy seems to have a surprising positive impact on the profits of the manufacturer and the retailer, while, at the same time, enhancing consumer welfare. Such a "wi...

Combating online piracy, a global menace facing the manufacturers of information goods, has remained a top priority for those manufacturers, as well as for governments around the world. Despite much stricter anti-piracy measures in recent times, this menace continues unabated. Apparently, the policy debate is now shifting from the efficacy of the e...

For accurate end-to-end (e2e) analysis of a real-time embedded system (RTES), we need a method to precisely reflect the effects of the underlying real-time operating system (RTOS). In timing analysis, RTOS can be viewed as a matrix of parameters that could affect the timing of the RTES. In this paper, we consider various RTOS parameters that may af...
