摘要：This study focuses on algorithmic interactions in open source work. Algorithms are essential in open source because they remedy concerns incompletely addressed by parallel development or modularity. Following algorithmic interactions in open source allows us to map the performance of algorithms to understand the nature of work conducted by multiple algorithms functioning together. We zoom to the level of algorithmic interactions to show how residual interdependencies of modularity are worked a...

摘要：This study presents a systematic comparison of methods for individual treatment assignment, a general problem that arises in many applications and that has received significant attention fromeconomists, computer scientists, and social scientists. We group the various methods proposed in the literature into three general classes of algorithms (or metalearners): learning models to predict outcomes (the O-learner), learning models to predict causal effects (the E-learner), and learning models to ...

摘要：We examine how social sharing of consumers' brand purchases affects brand competition in a market where different types of consumers, characterized by their distinct personal characteristics (i.e., personalities, hobbies, and lifestyles) and brand preferences (i.e., being loyal to one of two horizontally differentiated brands or neither), all desire accurate public perception of their true type. Social sharing of a consumer's brand purchase allows the public to infer the consumer's type, but s...

摘要：Many of today's software systems are created by leveraging ecosystems consisting of heterogeneous complementors and hub firms. In fact, the reliance on ecosystems is prevalent in the enterprise resource planning (ERP) domain, where larger ERP vendors form collaborative relationships with smaller industry-specific vendors to co-create value for themselves and their customers. However, value creation and destruction processes are often intertwined. A key motivation for this study is to shed ligh...

摘要：Online healthcare portals have become prevalent worldwide in recent years. One common formof a healthcare portal is the online consultation website, which provides a bridge between patients and doctors and reduces patients' time and cost when seeking healthcare services. Another form is the healthcare service appointment website, which facilitates offline visits for patients. Although nominally separate, the behaviors of the users (including patients and doctors) on these two types of websites...

摘要：Although digital platforms have become mainstream, there still remain some unanswered questions pertaining to managing platform ecosystems. One such unexplored question pertains to the effect of marquee sellers on the platform-marquee sellers arguably attract other sellers and buyers to the platform, thereby enhancing the platform's value. In this paper, we study how adding a marquee seller to a business-to-business (B2B) secondary-market platform for IT products affects other sellers, in term...

摘要：AWalrasian competitive equilibrium defines a set of linear and anonymous prices where no coalition of market participants wants to deviate. Walrasian prices do not exist in nonconvexmarkets in general, with electricitymarkets as an important real-world example. However, the availability of linear and anonymous prices is important for derivatives markets and as a signal for scarcity. Prior literature on electricity markets assumed price-inelastic demand and introduced numerous heuristics to com...

摘要：Online platforms often ask their users to refer friends in exchange for a reward. This paper addresses how referral generation and referral value evolve throughout the customer's life cycle as a function of service usage, experience level, and past referral behavior. Our analysis is based on a longitudinal data set that comprises the transactions and referral actions of 400,000 users in a ride-sharing platform over a year. The richness of our data set allows us to address two shortcomings from...

摘要：Recruitment is a critical activity for companies, and the research community has also shown significant interest in examining technology recruitment. Companies often communicate how they value their employees along with job requirements to potential candidates in a bid to attract them. However, there is an overall lack of understanding of how candidates react to such information and how their motivation toward the job changes with such online communication. Although there is substantial work t...

摘要：Social media platforms are facing increasing numbers of cyber-adversaries seeking to manipulate online discourse by using social bots (i.e., social media software robots) to help automate and scale their attacks. Likewise, some social media users can identify social bot activity at varying degrees of confidence. In this research, human reactions to social bot messages are used to augment existing social bot detection capabilities. Speech act theory is used to inspire a framework for assessing ...
