The association between financially expert independent directors and the accounting for employee stock options

This study investigates how the financial expertise of independent directors is associated with voluntary accounting policy decisions. As representatives of a company’s shareholders, financially-expert independent directors are more likely to cause management to pursue higher quality accounting policy decisions. The policy decision investigated involves the expense/non-expense policy choice for employee stock options as previously permitted under SFAS No. 123. Using a sample of 174 option-expensing firms and a matched control sample of 174 non-expensing firms, the results indicate a significant, positive association between the decision to expense employee stock options and the financial expertise of a company’s independent directors. Further, a significant, negative association was found between the option-expensing decision and whether the chief executive officer was the largest internal blockholder.     

信号消费、异质消费与公共产品自愿供给

传统的经典理论分析了政府供给公共产品和消费者无差别消费时的经济问题。然而在市场经济中消费者的类型是不相同的,对公共产品的消费需求也各不相同。对此,需要研究不同消费需求、不同供给模式下具有"消费信号"的公共产品自愿供给问题。研究发现,提高公共产品消费的信号性,优化公共产品的供给模式对于公共产品的自愿供给非常重要。同时,识别出"信号消费"下的异质消费者,并使公共产品具有私人产品的消费特征时,公共产品自愿供给的意愿将会增加。     

Unintended Effects of Preannouncements on Investor Reactions to Earnings News*

This study uses an experiment to examine three alternative theoretical explanations for the unintended effects of preannouncements on investor reactions to earnings news. The theoretical explanations are cue consistency, recency effects, and diminishing marginal reactions. The experiment varies the amount of a management preannouncement at five different levels while holding constant consensus analyst expectations prior to the preannouncement and the subsequent earnings announcement. Participants provide preliminary forecasts of current‐ and next‐period earnings per share (EPS) prior to the preannouncement, after the preannouncement, and after the earnings announcement. The pattern of participants' final next‐year EPS forecasts and the results of follow‐up analyses appear most consistent with the predictions of diminishing marginal reactions and, to a somewhat lesser extent, cue consistency, suggesting that both mechanisms play a role in determining the effects of preannouncements. There is little evidence supporting recency effects. Finally, supplemental evidence indicates that participants are unaware that preannouncements influence their reactions to earnings news, suggesting that the effects are unintended. This study has implications for managers who make preannouncement disclosure decisions and for academics who wish to understand and interpret prior research on earnings preannouncements.     

Análisis del servicio de Urgencias aplicando teoría de líneas de espera

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.     

Artificial intelligence activities and ethical approaches in leading listed companies in the European Union

This study explores the information regarding Artificial Intelligence (AI) included by European listed companies in their annual and/or sustainability reports. The study mainly focuses on (1) the development and use of AI systems/projects reported by companies, (2) the extent to which companies disclose ethical principles or guidelines regarding AI and (3) the factors explaining these practices.The study analyses the reports of 200 companies listed in the major indexes of Germany, Sweden, Finland, France, Spain, and Italy, both from qualitative and quantitative perspectives. All reports are analysed, using content analysis methodology, to identify expressions such as ‘artificial intelligence’, ‘machine learning’, ‘deep learning’, and ‘big data’, and then classified accordingly. The study’s findings suggest a growing interest in the above-mentioned technologies, although 41.5% of companies do not report any activity in the field of AI. The adoption of ethical approaches to AI is at a very preliminary stage, and<5% of companies report on that issue. The quantitative analysis shows that larger companies, companies in the Technology and Telecommunications industries, and companies based in Southern countries are more likely to disclose information on AI activity. The majority of companies that develop ethical principles are listed in the Northern region and belong to the Technology and Telecommunications industries.The study provides evidence of AI disclosure, a type of non-financial disclosure that has not been explored yet in the literature. Unlike existing studies, we propose a first definition of the topic and a taxonomy that can be used in further research on AI disclosure and can contribute to the development of KPIs in the field. Furthermore, this study provides a theoretical framework integrating some traditional theories, such as Voluntary disclosure theory, Signalling theory, and Legitimacy theory, specifically drawn to interpret AI disclosure practices, which can help with a further in-depth exploration of AI disclosure combining concurrent perspectives. The study’s results may serve as a starting point for researchers and companies interested in the topic.     

Analyst reputation and management earnings forecasts

Prior studies show that analysts with high reputation are influential in the market. This paper examines whether managers consider analyst reputation in shaping their voluntary disclosure strategy. Using Institutional Investor magazine’s All-American (AA) rankings as a proxy for analyst reputation, we find that the coverage of AA analysts is positively associated with the likelihood of quarterly management earnings forecasts (MEFs). We also find that AA analysts’ forecast optimism is more positively associated with the likelihood of MEFs than non-AA analysts’ forecast optimism when the firm is covered by AA analysts. Analyses based on AA analyst coverage changes and AA status changes confirm the relation between analyst reputation and MEFs. We further find that analyst reputation influences other MEF properties, such as forecast news, bias, and revisions, and that our results are robust to alternative measures of analyst reputation. Further analyses show that market reactions at quarterly earnings announcements are more positive (negative) when firms meet/beat (miss) AA analysts’ forecasts than when firms meet/beat (miss) non-AA analysts’ forecasts. Collectively, our findings suggest that managers strategically provide voluntary forecasts by taking into account the reputation of individual analysts following their firms.     

Does voluntary balance sheet disclosure mitigate post-earnings-announcement drift?

Theory suggests that balance sheet information such as total assets, total equity, or total liabilities complements earnings information in helping investors assess a firm’s profitability and estimate earnings growth. The voluntary disclosure of balance sheet information at earnings announcement could help investors gather and process this information at a lower cost. We therefore predict that voluntary balance sheet disclosure at the time of an earnings announcement helps investors promptly understand the implication of current earnings news for future earnings and subsequently reduces post-earnings-announcement drift (PEAD). Consistent with these predictions, our results show that when firms provide voluntary balance sheet disclosures, the earnings response coefficient in the event window is significantly higher and the corresponding PEAD is significantly lower. We further find that the impact of voluntary balance sheet disclosure on PEAD is more pronounced when the magnitude of balance sheet value surprise is larger, when balance sheet value is more informative about future earnings, when earnings uncertainty is higher, or when information cost is higher, consistent with our conjectures that helping investors to better understand future earnings performance and lowering information costs are key mechanisms underlying the effect of voluntary balance sheet disclosure on PEAD.     

Evolution of the slow living concept within the models of sustainable communities

The study presents analysis of three case studies of sustainable communities to reveal their distinctive features through the novel Functional Models of Sustainable Communities framework. The case studies signify phases of evolution of the slow living concept starting from the traditional representation (Model A), through the hybrid (Model B), to a more contemporary model (Model C). Based on the novel SLOW LIFE analysis, the study found that contrary to expectations the latest high-tech model of sustainable community in Masdar City failed to generate the same level of social cohesion and enjoyable living experience as evidenced in older, more established communities (Damanhur, and Toarps Ekoby). The study highlights the pivotal role of slow living concepts in the transitional period of the 21st century, moving towards the next ideational phase, according to Sorokin’s pendulum theory of social change. Further, the T-Cycle analysis revealed a converging trend in the shifting dialectical relationship between mainstream Western society and sustainable communities. The findings of this study indicate that evolution of the slow living concept in the context of sustainable communities followed broader trends in society—moving towards a more technologically oriented model.
