摘要：We analyze how the decline of a technology affects online labor market dynamics. We evaluate the effects of Steve Jobs' announcement that Apple would no longer support Adobe Flash-a popular set of tools for creating internet applications. Despite a precipitous decline in Flash demand, there is no evidence of a reduction in Flash wages on this platform because the supply response was rapid, particularly among younger developers with readily available fallback skills. The key to this rapid adjus...

摘要：Crowdsourcing contests have become increasingly popular as a means of seeking innovative solutions to business problems. However, the abundance of concurrent contests on platforms can lead to disparities in solvers' contest awareness, resulting in lost time-the time elapsed between the start of a contest and a solver's first visit. This study investigates how lost time influences solvers' submission behavior and its subsequent impact on matching inefficacy as measured by solver disqualificatio...

摘要：Cloud services exist under a shared security environment with a dynamic nature; users trade fixed costs for variable costs over time, and both cloud services providers (CSPs) and users contribute to overall security. We investigate the nature of shared security in a dynamic game where users' security contributions and cloud usage figure into their CSP's vulnerability. Furthermore, CSPs' own security contribution takes into account both their users as well as competition with other CSPs. The Ma...

摘要：Technostress is an emerging topic in the information systems (IS) literature. Prior studies have mostly adopted a static approach to capturing snapshots of technostressors, without considering their dynamic and episodic nature. Daily technostress is often the product of discrete events encountered in the workplace that shape employees' momentary affect and behaviors in situ. To lay the conceptual foundation for understanding deviant behaviors, this study integrates the self-regulation perspect...

摘要：Social media platforms, such as Facebook, often display assertive call-toaction ads that encourage direct conversion actions, such as purchasing a product or installing an app. Additionally, these ads can display popularity signals (i.e., likes) and social endorsement from friends (i.e., friends' likes). We examine the effectiveness of displaying these different signals on such ads in generating clicks through field tests conducted on Facebook. We collaborated with a mobile app company and con...

摘要：Recommender systems are widely used by online merchants to find the products that are likely to interest consumers, but existing dynamic methods still face challenges regarding diverse behaviors, variability in interest shifts, and the identification of psychological dynamics. Premised on the marketing funnel perspective to analyze consumer shopping journeys, this study proposes a novel machine learning approach for product recommendation, namely, multistage dynamic Bayesian network (MS-DBN), ...

摘要：Disaster response is critical to save lives and reduce damages in the aftermath of a disaster. Fundamental to disaster response operations is the management of disaster relief resources. To this end, a local agency (e.g., a local emergency resource distribution center) collects demands from local communities affected by a disaster, dispatches available resources to meet the demands, and requests more resources from a central emergency management agency (e.g., the Federal Emergency Management A...

摘要：Transportability is a structural causal modeling approach aimed at transporting a causal effect from a randomized experimental study in one population to a different population where only observational data are available. It offers a way to overcome the practical constraints in inferring causal relationships, such as endogeneity concerns in observational data and the infeasibility of replicating certain experiments. Although transportability holds significant promise for research and practice,...

摘要：Large firms are leaders in disaster response and communication. We study how firms communicate on social media during various disasters and the relationship between their communication and public engagement using a computationally intensive theory construction framework. The framework incorporates a novel natural language processing (NLP) approach, Semantic Projection with Active Retrieval (SPAR), as a key component of the method lexicon. Drawing on the two dimensions (internal versus external...

摘要：We consider an ad firm that acts on behalf of advertisers to execute mobile, in-app, ad campaigns. The firm commits to provide an advertiser a specified number of ad placements (impressions) on mobile apps, usually in a specified location, and within a specified time horizon. The supply for ad space arrives, in real time, in the form of bid requests from one or more mobile ad exchanges. The ad firm needs to bid on each impression in such a way that the goals of several ongoing campaigns are me...
