摘要：We theorize peer awards' effects on the volume and novelty of creative user -generated content (UGC) produced at online platform communities. We then test our hypotheses via a randomized field experiment on Reddit, wherein we randomly and anonymously assigned Reddit's Gold Award to 905 users' posts over a two-month period. We find that peer awards induced recipients to make longer, more frequent posts and that these effects were particularly pronounced among newer community members. Further, w...

摘要：Background. Influenza imposes heavy societal costs through healthcare expenditures, missed days of work, and numerous hospitalizations each year. Considering these costs, the healthcare and behavioral science literature offers suggestions on increasing demand for flu vaccinations. Yet, the adult flu vaccination rate fluctuated between 37% and 46% between 2010 and 2019. Aim. Although a demand-side approach represents one viable strategy, an operations management approach would also highlight th...

摘要：Online weight-loss communities (OWCs) provide individuals with various tools to support their weight management, such as weight recorders and weight-loss journals. These tools enable individuals to focus on different aspects of their self-regulation, including weight-loss outcomes and behavioral routines. Prior research, however, has not fully incorporated individuals' self-regulation focuses; thus, there is limited understanding of individuals' online weight-management dynamics as well as the...

摘要：We present evidence that unnecessarily complex disclosure can result from strategic incentives to shroud information. In our laboratory experiment, senders are required to report their private information truthfully but can choose how complex to make their reports. We find that senders use complex disclosure more than half the time. This obfuscation is profitable because receivers make systematic mistakes in assessing complex reports. Regression and structural analysis suggest that these mista...

摘要：Decades of research suggest that information exchange in groups and organizations can reliably improve judgment accuracy in tasks such as financial forecasting, market research, and medical decision making. However, we show that improving the accuracy of numeric estimates does not necessarily improve the accuracy of decisions. For binary-choice judgments, also known as classification tasks???for example, yes/no or build/buy decisions???social influence is most likely to grow the majority vote ...

摘要：Although extant literature investigates the role of sell-side equity analysts in capital markets, most studies do not consider that sell-side equity analysts often work in hierarchical teams. Lead analysts manage a team of associate and junior analysts who participate in the team's tasks. Building on the delegation theory in the management literature, we hypothesize and find a division of labor between lead and associate analysts, where lead analysts are more likely to delegate tasks (1) that ...

摘要：Many applied economic settings involve trade-offs between in-group members and strangers. To better understand decision making in these contexts, this paper measures and investigates the economic relevance of heterogeneity in moral universalism: the extent to which people exhibit the same level of altruism and trust toward strangers as toward ingroup members. We first introduce a new experimentally validated, survey-based measure of moral universalism that is simple and easily scalable. We the...

摘要：We examine how online customer reviews for one generation of a product affect sales of another generation in the same product series. The main intriguing result is that previous generation valence has a positive impact on current generation sales; however, current generation valence has a negative impact on previous generation sales. The positive impact of previous generation valence becomes even stronger (1) as the uncertainty (standard deviation) in reviews for the current generation increas...

摘要：A wide body of empirical research has revealed the descriptive shortcomings of expected value and expected utility models of risky decision making. In response, numerous models have been advanced to predict and explain people???s choices between gambles. Although some of these models have had a great impact in the behavioral, social, and management sciences, there is little consensus about which model offers the best account of choice behavior. In this paper, we conduct a large-scale compariso...

摘要：We find firms' work-related injury rates are negatively associated with the level of analyst coverage. This result is also robust at the establishment level at which we find local analysts have a more profound impact than distant analysts. Cross-sectionally, our results are exacerbated in firms with weak internal governance mechanisms and in industries with low union representation. Finally, management is more likely to discuss safety issues during earnings conference calls in the presence of ...
