The online response to customer complaints (i.e., service recovery) is a central feature of modern organizations' customer-focused performance management systems. Motivated by the lack of descriptive information related to complaint handling that can be used in assessing managerial performance, we collect organizations' responses to consumer complaints via Twitter and apply Zemke and Schaaf's (1990) traditional service recovery model to explore these. We collected 10,305 tweets that describe the use of Twitter for service recovery by organizations across four industries: airlines, casual dining chain restaurants, hotels, and fast-food restaurants. The findings show that in our sample, the traditional service recovery model with five service recovery elements (apology, urgent reinstatement, empathy, symbolic atonement, and follow-up) is implemented to various degrees. Furthermore, we identify three additional service recovery elements not previously discussed by prior research: channel transfer, feedback acknowledgment, and information request. Our findings have research implications and highlight the importance of incorporating online customer complaints into managerial performance systems.

This structured literature review synthesizes studies that have investigated questions related to anti-Black racism—namely, the discrimination and marginalization of Black people—in the accountancy literature and identifies opportunities for future research. This study is part of a larger research project that reviewed 161 articles and identified four themes relevant to accounting research on discrimination in general: anti-Black racism, imperialism and postcolonialism, intersectionality, and diversity. Based on the 25 anti-Black racism articles reviewed, this paper finds four key subthemes: demand for accountancy services and racial discrimination in accountancy practice, the racialization of professional accounting qualifications, Black professionals in academia, and the supply-side fallacy. Furthermore, because studies at the intersection of anti-Black racism and accounting are limited, this study proposes future research directions that will advance knowledge on various topics related to anti-Black racism.

This fictional case centers around a young Dutch couple who emigrated to Canmore, Alberta. Upon arriving, Saul and Rens opened two successful food trucks and are now looking to promote each truck's main chef to truck manager. They plan to offer a performance bonus based on the net income of each truck and have requested a local accounting student to advise them on the new bonus structure. Goode Food Trucks Inc. presents an opportunity for students to demonstrate technical competence in managerial accounting (rate methods, period cost allocation, and data visualization); strategy and governance (employee performance incentives); and financial reporting (reporting needs) while incorporating enabling competencies (communicating and adding value). The case and teaching notes were adapted from principles used to train and evaluate Chartered Professional Accountant (CPA) candidates and tailored to an appropriate level for undergraduate learners. MBA instructors may also use this case to apply multiple concepts in a defined context, thus enhancing a course's “real-life” applicability.

Peer recognition systems (PRS) have gained popularity in recent years as a means for organizations to promote employee helping behavior. However, there are theoretical reasons to believe that peer information that is publicly disclosed in PRS may reduce subsequent helping behavior, and I use an experiment to test my theory. Specifically, I examine a three-employee setting where an employee (the worker) receives no recognition for helping a coworker (the recognizer) but another coworker (the helper) does. I predict and find that the worker's willingness to subsequently help the recognizer/helper is lower when the worker perceives that the worker's initial help exceeds (vs. subceeds) the helper's. I also find that the worker's perception of fairness mediates the process, and the worker's willingness to help the recognizer has a spillover effect on the worker's willingness to help the helper. My study provides the first empirical evidence of the negative impact that PRS have on helping behavior.

This fictional case is based on a real specialty tea company in Nova Scotia. Ted's Teas is a two-part crossover case that illustrates the integration of financial accounting and audit learning outcomes applied to real-world scenarios. In Part 1, students assume the role of an internal accountant and apply knowledge of the Chartered Professional Accountants (CPA) of Canada's CPA Way to identify how to treat leases, changes in policy, and estimates as part of accounting knowledge under both Accounting Standards for Private Enterprises and IFRS frameworks. In Part 2, students “cross over” and change roles, so they are now external auditors for Ted's Teas, tasked to provide an analysis of risk of material misstatement, recommend an audit approach, and develop substantive procedures. This two-part case presents opportunities for students to demonstrate technical competence in multiple areas, either separately in two different courses or combined in one “capstone” or case course. The case and teaching notes, including the marking rubrics, were adapted from principles used to train and evaluate CPA Professional Education Program candidates, tailored to an appropriate level for undergraduate and graduate learners.

Companies spend significant amounts of money on tangible rewards programs, even during the economic turmoil of the COVID-19 pandemic. The prevalence, growth, and significance of these expenditures highlight the importance of understanding the purpose and use of these programs by organizations. Research on public accounting (PA) firms' compensation plans has focused on the balance between professional and commercial incentives in partner profit-sharing schemes but has failed to examine the incentives for nonpartner audit professionals. However, it is exactly these professionals who do a substantial amount of work on audit engagements. This paper has three main purposes. First, we investigate the nature and composition of PA firms' tangible rewards programs and provide a detailed description. Second, we examine the use of firms' tangible rewards programs to provide evidence of what actions are being rewarded. We use Almer et al.'s (2005, Behavioral Research in Accounting 17: 1–22) framework, which presents dimensions of the auditors' professional contribution, and explores whether firms recognize these dimensions using tangible rewards. Third, we develop future research questions to help explore the use of tangible rewards in firms without structured output. We collect archival data on the use of tangible rewards from each of the Big 4 PA firms and three of the next four largest international accounting firms in Canada. We find that firms use their tangible rewards programs for “building a culture of recognition,” for performance incentives, and for employee and firm development, thus rewarding a broad set of measures beyond the incentive measures for hours worked.

This study explores how key organizational and governance actors perceive the effectiveness of whistleblowing at nonprofit organizations (NPOs) and how whistleblowing is interrelated with other anti-fraud mechanisms. Using a systems approach, we develop a conceptual framework of anti-fraud mechanisms consisting of a set of interrelated components: control-focused mechanisms and employee-focused mechanisms (whistleblowing) intended to prevent and detect fraud, influenced by the environment (regulation and stakeholders) and human factors (employees' attitudes and leaders' awareness of fraud). We conducted 14 semistructured interviews with key actors at Canadian NPOs and noted that diverse control mechanisms were in place at these groups, but seemingly no formal whistleblowing policy existed. The organizations were disinclined to formalize a whistleblowing system in the short term despite viewing such a system as effective. Whereas prior research has examined the role of control-focused mechanisms, NPOs' adoption of whistleblowing systems, and the benefits thereof, we contribute to the literature by stressing that employee empowerment is crucial to overcoming reluctance to blow the whistle. If the board of directors is aware of fraud risk and provides employees with the resources, motivation, and protection to speak up, whistleblowing could be implemented in these organizations. Whistleblowing should be interrelated with other mechanisms to form an effective anti-fraud system.

This paper expands on a letter recently submitted by a group of Canadian business academics to the Independent Review Committee on Standard Setting in Canada (IRCSSC) in response to the committee's proposed Canadian Sustainability Standards Board. We highlight sections of the IRCSSC's Consultation Paper that we find problematic and draw on accounting and other research to explain why it fails to live up to its potential. Chief among the problems we identify is that the IRCSSC appears to be wedded to the same narrow, investor-based focus promoted by the International Sustainability Standard Board. We also draw attention to the rushed nature of the process, its exclusion of lay experts, the IRCSSC's ambiguous use of the term public interest, and its inattention to alternative understandings of value and the environment (including the people within it). Finally, we problematize the IRCSSC's sidestepping of the issues of power, culture, and conflict; its neglect of monitoring and enforcement; and its surprising disregard of the Global Reporting Initiative. Along with a number of suggestions for improving the process and its outcome, this paper also contributes to ongoing debates on standard setting and the question of whether accounting is currently equipped to provide the necessary tools for sustainability reporting.
最近,一群加拿大商业学者向加拿大标准制定独立审查委员会(IRCSSC)提交了一封信,以回应该委员会提议的加拿大可持续标准委员会。我们强调了IRCSSC咨询文件中我们发现有问题的部分,并利用会计和其他研究来解释为什么它没有发挥其潜力。我们发现的主要问题是,IRCSSC似乎与国际可持续发展标准委员会(International Sustainability Standard Board)倡导的狭隘的、以投资者为基础的关注相结合。我们还提请注意这一过程的匆忙性质,它将外行专家排除在外,IRCSSC对“公共利益”一词的模糊使用,以及它对价值和环境(包括其中的人)的替代理解的忽视。最后,我们提出了IRCSSC回避权力、文化和冲突问题的问题;忽视监督和执法;以及它对全球报告倡议组织的惊人漠视。除了提出一些改进流程及其结果的建议外,本文还有助于就标准制定和会计目前是否具备为可持续发展报告提供必要工具的问题进行辩论。
