摘要：We investigate the impact of using smartphones in the classrooms on students' academic performance. We collaborated with a vocational school in China to randomly allocate students taking Chinese verbal lectures into one of four experimental conditions: (i) smartphones banned, (ii) smartphones allowed and used at will by students without guidance, (iii) smartphones allowed and used at will by students with teachers prompting students to use the smartphones to assist instruction, and (iv) smartp...

摘要：The emotionality expressed in social media posts is a crucial driver of social media engagement. Limited work, however, has considered how features of the target audience moderate the effectiveness of content characteristics such as emotionality. In the political domain, understanding the impacts-and potential limitations-of emotionality in political communications has taken on new urgency because multiple stakeholders stand to benefit from decreased political emotionality. In this research, w...

摘要：Despite growing interest in how artificial intelligence (AI) affects the labor market, there is limited understanding of the labor-related factors driving firms to invest in AI. Drawing on the institutional perspective of media coverage, we propose that media exposure of labor issues exerts reputational pressure on firms, heightening their awareness of the necessity and urgency to address these problems. Consequently, firms are driven to invest in AI as a potential solution, given its capabili...

摘要：As organizations increasingly use large language models (LLMs) in delegated decision tasks, understanding and auditing their outputs is important for responsible deployment. However, despite LLMs' widespread adoption, systematic tools for interpreting and auditing their decision outputs are limited. We introduce a probabilistic auditing framework, state-understanding-value-action (SUVA), to evaluate LLM behavior based on textual responses. SUVA assesses LLMs through both their final decisions ...

摘要：Intensive care units (ICUs) are critical for treating severe health conditions but represent significant hospital expenditures. Accurate prediction of ICU length of stay (LoS) can enhance hospital resource management, reduce readmissions, and improve patient care. In recent years, widespread adoption of electronic health records and advancements in artificial intelligence (AI) have facilitated accurate predictions of ICU LoS. However, there is a notable gap in the literature on explainable art...

摘要：Mobile apps are among the most important and widely used financial technology (fintech) innovations in the brokerage industry. Surprisingly, despite their increasing economic importance and theoretical significance, few studies examine the effects of mobile app use on individual investors' financial decisions and performance. This study seeks to understand how mobile apps influence investors' trading behaviors and portfolio performance by using a proprietary longitudinal data set from December...

摘要：Platform owners are releasing their own apps on their platforms. These first-party apps (FPAs) typically leverage platform resources more effectively, competitively threatening rivals. Although the impact of FPAs on rivals' innovation has been the subject of extensive study, the dominant view in previous research assumes that these FPAs are closed to third-party apps (TPAs). However, there is an increasing trend of FPAs opening their resources to TPAs, as they provide application programming i...

摘要：How does information on a rival's expertise influence the focal user's engagement in online competitive settings? Online competitive settings differ fundamentally from other online contexts, such as e-commerce and social media platforms, explored in the prior work. This contextual distinction, we argue, is important as it determines the relationship between information about others and the focal user's engagement. The relevance of this question relates to broader theoretical ambiguities concer...

摘要：Extracting psychological constructs from text is increasingly essential for social science researchers who study attitudes, perceptions, and traits across digital communication. This paper offers the first holistic comparison of four major approaches used for this purpose-lexicons, custom-built machine learning models, fine-tuned masked language models, and large language models (LLMs). We evaluate these paradigms across multiple performance dimensions and integrate insights from dual-process ...

摘要：Third-party skill certification is widely employed to address the ubiquitous information asymmetry between workers and employers. Offering certification tests at zero cost could be a natural strategy to encourage workers to certify their skills; however, neither theoretical nor empirical studies have examined how employers react to such a policy. This research fills that gap. First, we develop a stylized model to theorize the effects of free certification tests on employers' recruitment decisi...
