The use of models for detecting earnings management in the academic literature, using accrual and real manipulation, is commonplace. The purpose of the current study is to compare the power of these models in a United Kingdom (UK) sample of 19,424 firm-year observations during the period 1991–2018. The authors include artificially-induced manipulation of revenues and expenses between zero and ten percent of total assets to random samples of 500 firm-year observations within the full sample. The authors use two alternative samples, one with no reversal of manipulation (sample 1) and one with reversal in the following year (sample 2).

The authors include artificially induced manipulation of revenues and expenses between zero and ten percent of total assets to random samples of 500 firm-year observations within the full sample.

The authors find that real earnings manipulation models have lower power than accrual earnings manipulation models, when manipulating discretionary expenses and revenues. Furthermore, the real earnings manipulation model to detect overproduction has high misspecification, resulting in artificially inflating the power of the model. The authors examine an alternative model to detect discretionary expense manipulation that generates higher power than the Roychowdhury (2006) model. Modified real manipulation models (Srivastava, 2019) are used as robustness and the authors find these to be more misspecified in some cases but less in others. The authors extend the analysis to a setting in which earnings management is known to occur, i.e. around benchmark-beating and find consistent evidence of accrual and some forms of real manipulation in this sample using all models examined.

This study contributes to the literature by providing evidence of misspecification of currently used models to detect real accounts manipulation.

Based on the findings, the authors recommend caution in interpreting any findings when using these models in future research.

The findings address the earnings management literature, guided by the agency theory.

This chapter investigates whether earnings management activities increase the likelihood of receiving a qualified audit report. We have carried out this study with a sample of Spanish companies for the period 2001–2009. Previous research on the issue is not only scarce but also suffers from methodological pitfalls. In all cases, researchers have followed a matched sample approach without considering the implications of such approach for the statistical analysis. Despite its great popularity among researchers in accounting, the use of matched-based sampling is susceptible to produce technical errors in the statistical analysis. The main problem consists in the generalization of results obtained with a nonrandom sample to the whole population of firms. Our results do not show a significant relationship between EM and qualified audit reports. We have also addressed whether the international financial crisis has affected our results and concluded that Spanish companies seem to have used EM during the crisis to push down earnings, probably expecting to take advantage of the positive earnings surprises during the postcrisis period. Nevertheless, the financial crisis has not changed the nature of the EM-qualified opinions relationship.

This study examines whether Brazilian health insurance companies (HICs) engage in earnings management through discretionary accruals or operational decisions by refraining from reporting a low indicator of sustainability in the market (IDSM).

The study used the Jones and Modified Jones models to identify earnings management through discretionary accruals and used the model described by Roychowdhury to estimate the abnormal behaviors of operational decisions. Data covering 2012 to 2018 were collected from the ANS website.

The results show that HICs engaged in earnings management to avoid reporting a low IDSM. The findings should help health insurance clients make decisions regarding the purchase or change of health insurance. The findings should also encourage regulators to improve their evaluation of the economic and financial risks around HICs.

The National Agency of Supplementary Health (ANS) established a qualification program for HICs, monitoring them based on a set of indicators. Managers may have an incentive to use earnings management to obtain indices that meet the requirements of the ANS qualification program in order to avoid showing signs of abnormality.

本研究旨在探討巴西的醫療保險公司，透過避免報導低的市場可持續性指標，是以裁決性應計，抑或是以操作決策來進行盈餘管理。

國立輔助醫療辦事處 (註：此為直譯)(The National Agency of Supplementary Health)為醫療保險公司建立了一個資格檢定機制，基於一套指標來監管這些公司。公司主管或會有鼓勵性的誘因去使用盈餘管理來取得符合國立輔助醫療辦事處資格檢定機制所要求的指標，從而避免顯示異常的跡象。

本研究使用Jones 模型及Modified Jones模型，透過裁決性應計來辨認盈餘管理，研究亦使用羅伊喬杜里 (Roychowdhury) 描述的模型， 來估計操作決策的異常行為。數據取自國立輔助醫療辦事處的網址，並涵蓋2012年至2018年期間。

研究結果顯示，醫療保險公司進行盈餘管理，以求避免報導低的市場可持續性指標。研究結果應可幫助醫療保險客戶在購買或更改醫療保險時作適當的決定。研究結果亦可鼓勵監管者改善他們對醫療保險公司的經濟及財務風險所作的評估。

This study aims to identify and compare the measurement models of earnings management (EM) appropriate to the Iranian Islamic banking system. The importance of reported profit figures has motivated business executives, who also perform financial reporting, to manipulate these figures. These measures are referred to as “earnings management,” which negatively influence the quality of reported earnings and financial statements' reliability.

In this study, four methods, namely, Jones (1991), modified Jones (Dechow et al., 1995), Kasznik (1999) and Kothari et al. (2005), were used to measure the EM index in 25 Iranian Islamic banks (IBs) registered with the Tehran Stock Exchange and/or the Central Bank of Iran. The study covered the period 2005–2020. Following the aforementioned methods, this research implemented templates that were repeatedly tested in subsequent studies using accruals to discover EM.

The results show that the Kasznik (1999) model is the preferred and compatible model with the Iranian Islamic banking system's accrual behaviour due to the consistency of the measurement coefficients with theoretical and previous research findings. Therefore, total accruals, including discretionary accruals and non-discretionary accruals, have the most correspondence with (1) property, machinery and equipment; (2) the change in cash flow from operating activities; and (3) the difference of change in revenue (ΔREV) and change in net receivable accounts (ΔREC).

This is the first investigation in the Iranian Islamic banking system. The research contributes to the Iranian Islamic banking system literature on the implements of EM, which could be appealed to in the context of developing countries like Iran. Finally, this study highlights the different EM capabilities in Islamic banking systems similar to the Iranian banking arrangement.

Accounts manipulation has been the subject of research, discussion and even controversy in several countries including the USA, Canada, the U.K., Australia, Finland and France. The objective of this paper is to provide a comprehensive review of the literature and propose a conceptual framework for accounts manipulation. This framework is based on the possibility of wealth transfer between the different stake‐holders, and in practice, the target of the manipulation appears generally to be the earnings per share and the debt/equity ratio. The paper also describes the different actors involved and their potential gains and losses. We review the literature on the various techniques of accounts manipulation: earnings management, income smoothing, big bath accounting, creative accounting, and window‐dressing. The various definitions of all these, the main motivations behind their application and the research methodologies used are all examined. This study reveals that all the above techniques have common elements, but there are also important differences between them.

In this paper, the authors examine the association between the amount of continuing professional education (CPE) hours per staff and audit quality in terms of discretionary accruals and audit opinion.

Several methodologies are adopted to test the hypotheses, including the ordinary least square (OLS) and logistic regression (Logistic). The authors also employ instrument variables regression with two least square (IVREG with 2SLS) and instrument variables probit model (IVProbit) to address the possible endogeneity and strengthen the validity of the main estimation results.

The main results show that there is a positive and significant relationship between CPE hours per staff and audit quality. As the authors grouped CPE into four areas (finance, auditing and accounting, tax, law and regulations and others) the results are more robust for the sub-sample “accounting and audit” and “others”. Moreover, the findings of this study suggest that CPE hours per staff do not affect audit quality significantly for Big4 audit firms compared to non-Big4 firms.

The sample size of the present study is quite small because the transparency reports of the audit firms in Turkey have been available since 2013 and the authors could not reach some auditor demographics at the individual level and some attributes at the audit firm level. Besides, some alternative audit quality measures, such as audit effort, audit fees are not employed because they are not disclosed.

This study contributes to the audit literature using Turkish audit firms. The authors believe that the setting of Turkey may yield interesting results because of the data it provides.

This paper aims to investigate whether the value relevance of accounting information has been affected by the occurrence of the Egyptian revolution financial crisis. More specifically, this paper examines the value relevance changes of three key accounting constructs: operating cash flow, normal non-discretionary accruals and discretionary accruals before and after the Egyptian revolution crisis.

Ordinary Least Squares (OLS) regression is used to examine the changes in earnings value relevance across before and after the Egyptian revolution crisis. The performance matched Jones model (Kothari et al., 2005) is used to estimate the discretionary accruals.

After the Egyptian revolution financial crisis, the discretionary accruals (DAC) information value has significantly improved. However, the non-discretionary earnings components (OCF and NDAC) have minimal changes. The evidence of further analysis indicates that managers are using the discretionary accruals to signal the future adding value investments that respond optimally to changes in discount rates.

The paper extends the literature debate about earnings management over a financial crisis; the findings provide implications for regulatory bodies that could learn how the common incentives of firms to attract potential investors during a crisis could lead them to provide a high-quality financial reporting.

Using data from the Egyptian market, the paper fills a research gap by examining the value relevance of earnings and tests whether the revolution crisis has influenced earnings reporting and firms’ values from a relatively developing country with special institutional and enforcement backgrounds.

This study explores whether hard regulatory control decreases the level of earnings management in local governments. The implementation of a new regulatory approach by Norwegian authorities provides the opportunity for an empirical study.

The authors adopt a two-stage strategy to investigate the existence of earnings management, using the Jones (1991) and modified Jones (Dechow et al., 1995) models to construct a random-effects model.

The authors test the hypothesis that, given decentralisation of control, there will be an increase in opportunistic financial reporting. This study's findings suggest that this is not the case, thereby indicating that a soft control regime does not diminish discipline in municipalities.

This study has practical implications for policymaking in the public sector. Its findings suggest that municipalities do not engage in more earnings management under a soft regulatory regime. Hence, other authorities should consider adopting a soft regulatory approach to controlling local governments and their financial reporting systems.

This study contributes to a growing body of literature regarding earnings management by local governments. The authors investigate a hypothesis previously untested in the literature by comparing the degree of earnings management under different regulatory control regimes.

The purpose of this study was to determine the influence of the elements of the fraud diamond theory in detecting financial statement fraud among non-financial firms in Kenya. Secondary data used to calculate ratios and figures representing the study variables was collected using a checklist for each of the targeted firms listed in the Nairobi Securities Exchange in Kenya for the 2013-2017 period.

Secondary data used to calculate ratios and figures representing the study variables was collected using a checklist for each of the targeted firms listed in the Nairobi Securities Exchange in Kenya for the 2013-2017 period. Convenience sampling technique was used to come up with a sample size of 35 out of the targeted population of 45 non-financial firms listed in Kenya (78% representation). This sample size was representative enough of the targeted population.

The results strongly supported that all the four elements of the fraud diamond triangle influenced financial statement fraud in Kenya. However, using three parameters, namely R², predicted sign and standard error, to compare the applicability of either the Yoon et al. (2006) or the modified Jones (1991), our study findings are mixed. It is therefore imperative that a new model should be developed in detecting earnings management in the Kenyan context. Note that including other variables will to a greater extent increase the explanatory power in detecting earnings management practiced by non-financial firms listed in Kenya.

Use of secondary information in the study was one limitation. Certain financial information was missing from some of the targeted firms’ official websites and the Nairobi Securities Exchange research handbooks. The researcher ensured that only non-financial firms whose audited financial statements were easily accessible were included in the study. Firms whose records were not readily available were excluded from the survey.

Practically, this study enables regulatory authorities in Kenya to understand the extent with which each element of the fraud diamond theory could be relied on in detecting financial statement fraud. Moreover, it will advise them on the areas to lay more emphasis when attempting to detect financial statement fraud using this model.

The main value of this study is the determination of the key elements of the fraud diamond theory, which have influence on financial statement fraud among non-financial firms listed in Kenya.

In periods of economic distress, expectations for businesses change and there is a heightened need for reporting quality. This study investigates the impact of crises on earnings management in the real estate sector.

The data consisted of financial statements from 2005 to 2021 from real estate firms listed on 10 European stock exchanges. Estimated discretionary accruals from four standard accruals models were used as a proxy for earnings management, using cross-sectional industry and firm fixed effects models. The authors examined earnings management during three crises: the financial crisis (2008–2009), the debt crisis (2011–2012) and the COVID-19 pandemic (2020–2021).

The results showed less earnings management during the COVID-19 crisis and more earnings management during the financial crisis, though with slightly weaker evidence. The authors did not find significant evidence of earnings management related to the debt crisis. These results suggest that stakeholders in the real estate sector should be extra vigilant in crisis periods.

This study is the first to investigate earnings management in European real estate firms, focusing on the impact of crises.
