This article focuses on the selenium (Se) content of 29 legumes and grains available in Mauritius. Selenium was determined using an ultraviolet/visible spectrophotometric method. Results showed that there was considerable variation in the Se content of the legumes and grains that varied from 0.009 ± 0.003μg/g in Dhall Mung (Phaseolus areus) to 1.380 ± 0.003μg/g in Gram Noir (Cicer arietinum). The overall mean Se content of the legumes and grains analysed was 0.231 ± 0.00μg/g. In conclusion, the present study tends to show that legumes and grains are important vehicles of Se intake in the Mauritian diet.

This study reviews the existing literature on the U.S. peer review system and the Public Company Accounting Oversight Board (PCAOB) inspection system to assess our knowledge of audit regulation. The traditional self-regulatory system of the accounting profession came to an end, in 2002, when the PCAOB was established to oversee the audit firms of publicly traded companies. This paper contributes to the controversial debate about self-regulation versus independent regulation by analyzing, categorizing, and comparing the research findings on the peer review system and the PCAOB system along three dimensions: the validity of peer reviews and PCAOB inspections, the recognition of reviews and inspections by decision-makers (e.g., investors, bankers, committees), and the effect of reviews and inspections on audit quality. Synthesizing the research on the regulatory regimes suggests that the notion of external quality control, both through peer reviews and government inspections, is positively linked with an improvement of audit quality. At the same time, the analysis indicates that external users do not seem to recognise peer review and PCAOB reports as very useful instruments for decision-making, which is in line with an identified rather skeptical perception of the audit profession on reviews and inspections. Overall, this study reveals that although the academic literature on peer review and PCAOB inspection is extensive it has not produced definitive conclusions concerning various aspects of audit regulation. This paper shows how this blurred picture is due to conflicting research findings, the dominance of the quantitative research paradigm, and unchallenged assumptions within the literature, and concludes by proposing research opportunities for the future.

This paper aims to examine the effect of managerial ability (MA) on real earnings management and the effect of real earnings management by higher ability managers on future profitability, at a different level of the crime rate.

The research sample includes 864 manufacturing firms-years listed on the Indonesian Stock Exchange. MA uses an efficiency score by data envelopment analysis. Real earnings management is measured by abnormal activities. The crime rate is measured by logarithm natural of the number of crimes per 100.000 citizens in the region where the firm is headquartered. Data analysis uses fixed-effect regression.

MA increases real earnings management in the region where the firm is headquartered with a higher crime rate while MA will reduce real earnings management in the region where the firm is headquartered with a lower crime rate. Also, real earnings management by higher-ability managers gives a signal of better future profitability in the region where the firm is headquartered with a lower crime rate.

This research contributes to filling the previous gap of managerial characteristics ability-related on real earnings management by providing regional crime rate as a determinant factor of managers’ ethical behavior. This research is the first one to considers the regional crime rate treatment to the relationship between MA and real earnings management especially in Indonesia. This research also provides new evidence of efficient real earnings management for a lower crime rate group of samples to give a signal of better future profitability.

A long-time ethical issue in financial accounting is earnings management. Two popular ways that earnings are managed include use of accruals (Kothari et al., 2016) and real activities management (RM). This study examines the association between RM and short selling and an association between short sellers and RM behavior related to earnings management. Instead of using accruals, RM is accomplished by timing investment or financing decisions and thereby alter reported earnings. Our results show that short sellers avoid targeting firms with a high level of RM, but this only holds for those firms that just meet analysts’ forecasts. This result suggests that short sellers interpret RM as a signal used by companies to convey their “good news” and confidence in their future performance. On the other hand, the authors document that heavily shorted firms engage in a lower amount of RM, which is consistent with the notion that short selling plays an external disciplinary role in constraining firms’ RM behavior for earnings management. This chapter would be of interest to anyone concerned with earnings management, such as financial market analysts, investors, academic researchers, and, in particular, regulators, who are involved in setting rules on short selling.

We investigate the effect of the PCAOB’s Part II report on annually inspected firms’ audit fees and audit quality. The PCAOB replaced the peer review auditor program with an independent inspection of audit firms. Upon completion of each inspection, the PCAOB issued inspection reports that include a public portion (Part I) of identified audit deficiencies, and (in most cases) a nonpublic portion (Part II) of identified quality control weaknesses. The Part II report is only made public when the PCAOB deems that remediation was insuffcient after at least 12 months have passed. Starting around the time of the 2007 Deloitte censure (Boone et al., 2015), the PCAOB shifted from a soft synergistic approach to an antagonistic approach, such that Part II reports were imminent, despite delays that ultimately led to their release one to four years later than expected. Our study spans the period from 2007 to 2015, and examines the effect on audit fees and audit quality at the earliest date that the Part II report could have been released – 12 months after the Part I report was issued. We find that following the 12 month period, that annually inspected audit firms eventually lost reputation by lower audit fees, while they concurrently made remedial efforts to increase the quality of their client’s financial reporting quality (abnormal accruals magnitude and restatements). However, three years after the Part II report was actually released, audit fees increased.

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

REM models infer abnormal levels of cashflow from operations (AbCFO), selling, general and admin (AbSGA) and production expenses (AbProd) are opportunistic, based on the supposition that engaging in real activities to meet current earnings targets (t) will negatively influence future performance (t+1). However, from a firm productivity perspective, cost reduction (via AbCFO, AbProd and AbSGA) is interpreted as an efficiency enhancing business strategy. This study therefore differentiates between (1) firms with ineffective management that have engaged in AbCFO, AbProd and AbSGA to achieve an optimal resource-cost mix to generate sales (REMF) and (2) firms with effective management that have not (OEF).

Using a sample of Korean listed firms over the 2000–2016 sample period, the study utilizes data envelopment analysis to capture the capability of management to generate sales from resources that are directly under their control. The study then compares the incremental effect that managerial decision making can have on real earnings management (REM) and future firm performance (period t+1 to t+5).

The study makes two important contributions. First, consistent with the efficiency/productivity literature, but contrary to seminal REM studies, empirical results shows that AbCFO, AbProd and AbSGA improve firm performance in period t and t+1 (to t+5), demonstrating “REM” is not opportunistic by default. Second, OEF have higher financial performance compared to REMF, in periods t and t+1.

The study therefore invokes resource-based theory and data envelopment analysis to integrate managerial effectiveness (human capital) into REM modelling. The study therefore extends the basic REM residual model.

Recent literature suggests that sin firms (firms in tobacco, gambling and alcohol industries) have lower institutional ownership, fewer analysts following, higher abnormal returns and higher financial reporting quality. This study aims to investigate empirically how sin firms engage in real activities manipulation (RAM) to meet earnings benchmarks in comparison to non-sin firms.

The authors examine two types of RAM, namely, Cutting discretionary expenditures including research and development (R&D), SG&A and advertising to boost earnings. Extending deep discount or lenient credit terms to boost sales and/or overproducing to decrease COGS to increase gross profit. Consistent with Roychowdhury (2006), the authors use abnormal discretionary expenditures as the proxy for expenditure reduction manipulation and abnormal production costs as the proxy for COGS manipulation.

The results for the abnormal discretionary expense model suggest that sin firms do not engage in RAM of advertising, R&D, SG&A expense to just meet earnings benchmarks. The results for the production costs model suggest that sin firms do not engage in COGS manipulation to just meet earnings benchmarks. The results are robust after controlling accrual-based earnings management (AEM). Overall, in this setting, these results suggest that managers of sin firms engage less in RAM to meet earnings benchmarks.

The findings are of interest to investors, auditors, regulators and academics with respect to financial statement analysis and earnings quality.

For the past 10 years, the Public Company Accounting Oversight Board (PCAOB) has operated as an independent overseer of public company audits. Over 70 percent of PCAOB studies have been published since 2010, evidencing the increasing relevance of PCAOB-related research in recent years. Our paper reviews the existing literature on the PCAOB’s four primary functions – registration, standard-setting, inspections, and enforcement. In particular, we examine PCAOB registration trends and evaluate the effects of PCAOB registration requirements on the issuer audit market, as well as discuss the relative costs and benefits (e.g., auditor behavior changes, improvements in audit quality, auditor perceptions) of the 16 auditing standards the PCAOB passed in its first 10 years of operation. Further, we summarize the literature’s findings on the effects of the PCAOB inspection process on various facets of audit quality. Finally, we analyze the research concerning the PCAOB’s enforcement actions to determine how markets have responded to sanctions against auditors and audit firms. We contend that understanding and reviewing the effects of the PCAOB’s activities are important to future audit research because of the PCAOB’s authority over and oversight of the issuer audit profession. We also identify PCAOB-related research areas that have not been fully explored and propose several research questions intended to address these research areas.

The purpose of this study is to investigate whether within the same firm, earnings risk is exacerbated in the fiscal year end (FYE) quarters relative to that of other quarters, more importantly, if this type of earnings risk is unique. Further, the authors discuss solutions to mitigate this type of information risk.

This study provides evidence that the information risk associated with FYE quarter earnings cannot be explained by other identified risk factors. Solutions to mitigate this risk include strong corporate governance and a more streamlined financial reporting structure.

The paper shows that there is significantly lower earnings response coefficient for FYE quarters than for non-FYE quarters (1984–2015). Furthermore, strong corporate governance and a more streamlined financial reporting structure, either by firms willingly reducing the usage of extraordinary item reporting or by FASB codification changes such as FASB 145, can help mitigate this type of information uncertainty.

This study explains that the causes of the exacerbated information risk associated with FYE quarter earnings identified in prior literature, namely, the “integral explanation” and “manipulation explanation,” are not mutually exclusive. Therefore, the authors deem it futile to disentangle the two. Instead, the authors offer two possible solutions.
