Abstract

Purpose

This study aims to concern about the relationship between management managerial attributes (management entrenchment, narcissism and overconfidence of the chief executive officer, board effort and real and accrual earnings management) and comparability of financial statements listed firms on the Tehran Stock Exchange. In other words, this paper aims to answer the question that “whether managerial attributes contribute significantly to the comparability of financial statements or not”.

Design/methodology/approach

The multivariate regression model is used for hypothesis testing. The hypotheses were examined using a sample of 768 listed observations on the Tehran Stock Exchange during 2012–2017 and by using from the multivariate regression pattern based on panel data techniques and the random-effects model.

Findings

The obtained results show a significant and negative relationship between management entrenchment, real and accrual earnings management, comparability and the relationship between management narcissism, overconfidence and board effort and comparability of financial statements is positive and significant.

Originality/value

As the present study is the pioneer study on such topics in the emerging markets, it provides valuable information concerning the intrinsic and acquired features of the management for users, analysts and legal institutions with a considerable impact on the comparability of financial statements. Moreover, this study’s results contribute significantly to the development of science and knowledge in this field and fill the gap in the literature.

Abstract

Purpose

The present study attempts to assess the relationship between management characteristics (managerial entrenchment, CEO narcissism and overconfidence, managers' myopia, real and accrual-based earnings management) and financial statement readability of listed firms on the Tehran Stock Exchange. In other words, this paper seeks to answer the question that “whether management characteristics have a favorable effect on financial statement readability or not.”

Design/methodology/approach

Multivariate regression model is used to meet the purpose of this study and research hypotheses are also examined using a sample of 1,050 listed observations on the Tehran Stock Exchange during 2012–2017 and by employing multiple regression patterns based on panel data technique and fixed effects model. Moreover, exploratory factor analysis of six variables (tenure, board independence, CEO duality, CEO ownership, board compensation and CEO change) is used for calculating managerial entrenchment and the FGO index is used for measuring readability.

Findings

The obtained results show that there is a negative and significant relationship between managerial entrenchment and accrual-based earnings management and a positive and significant relationship between real earnings management, managers' myopia, managers' narcissism and overconfidence and financial statement readability.

Originality/value

Since the present study is the first paper to investigate such a topic in the emerging markets, it provides useful information about intrinsic and acquisitive characteristics of management for accounting information users, analysts and legal institutions that contribute greatly to financial statement readability. Besides, the results of this study aid the development of science and knowledge in this field and fill the existing gap in the literature.

Abstract

Purpose

This study aims to assess the relationship between managerial entrenchment and the chance of fraud in financial statements, which are the only available source for shareholders’ decisions, so their accuracy and reliability are of great importance. Hence, the realization of contributing factors to preventing financial information distortion is vital. Moreover, managerial entrenchment on the chance of fraud in the company’s upcoming years has also been analyzed.

Design/methodology/approach

The factor analysis of five variables [chief executive officer (CEO) duality, managerial ownership, board independence, board compensation and CEO tenure] is used for management entrenchment. To examine the hypothesis testing, multivariate regressions, feasible general least squares regression and Logit model regression are used. The statistical sample under study in this paper includes 1,122 year-company observations during 2013–2018 and Beneish’s (1999) model is used for evaluating fraud.

Findings

The study results show a negative and significant relationship between management entrenchment and the chance of fraud in financial statements. That means managers with a higher degree of managerial entrenchment are more likely to create value and acquire wealth for the firm, and that causes them not to waste and waste the firm resources through enhancing the supervisory mechanisms. Moreover, the study results also show that improving and strengthening management entrenchment will lower the upcoming years’ fraud condition.

Originality/value

The current paper is the first time that the relationship between managerial entrenchment and financial statement fraud is assessed within a study. The results of the paper help the beneficiaries and shareholders realize different aspects of management entrenchment. That means managers’ power and authority can be used to make shareholders’ interests, but they can hinder misuse and fraud.

Abstract

Purpose

The citizen-shareholder approach in the capital market is considered a knowledge-enhancing and emerging concept in financial and accounting offerings. Its reliable background in management and human sciences makes it an essential basis for protecting the interests of shareholders and investors. Shareholders are considered a necessary part of the social platforms that are companies and regulatory institutions in the capital market; beyond being obligated to protect their material and intellectual rights, they are responsible for developing norms and facilitating investment values and gaining trust through mutual interactions based on respect for their interests. The purpose of this paper is to perform interactive qualitative analysis of the requirements for protecting the rights of citizens of capital market shareholders.

Design/methodology/approach

The methodology of the research is mixed, so that in the qualitative part, through content screening, the dimensions related to the protection of the citizen rights of the capital market shareholders were identified through a systematic review of 10 research in the period of 2017–2022. Then, the reliability of the specified dimensions was examined through Delphi analysis; in the quantitative part of the research, the criteria identified through the pairwise comparison matrix were first determined by the level of their relationships to determine based on the pattern of systemic representation of drivers and the consequences of requirements to protect the rights of citizens of capital market shareholders.

Findings

The research results in the qualitative part indicated the existence of 12 primary themes; during the two stages of Delphi analysis, three themes were removed, and a total of nine themes entered the quantitative phase. The results in a quantitative part indicate the creation of specialized and active committees of the board of directors as the primary driver and the reliability and timely disclosure of information in the long term as a systemic consequence.

Originality/value

To the best of the authors’ knowledge, this is the first research that presents the new concept of citizen shareholders to strengthen the requirements of protecting the rights of shareholders in the capital market while developing new theoretical literature.

Abstract

Purpose

Aims to investigate the inhibitive effect of the new series of Schiff base molecules, namely, N, N′‐ethylen‐bis(salicylidenimine) [S1], N, N′‐isopropylen‐bis(salicylidenimine) [S2] and N, N′‐Ortho‐phenylen acetyl acetone imine, (2‐hydroxy Benzophenone imine) [S3] on corrosion of copper during acid pickling treatment in 1 M HCl solution. Effects of concentration and temperature on the inhibition efficiencies of the selected Schiff bases have been studied systematically.

Design/methodology/approach

All inhibition experiments were conducted on copper sample in 1 M HCl solution. Weight loss measurements were carried out according to the ASTM standard procedure. Polarization curves and impedance spectra were carried out in a three‐electrode cell assembly connected to an EG&G potentiostat M273 and frequency response analyzer M1025.

Findings

Results obtained revealed that the studied Schiff bases act predominantly as cathodic inhibitors. The variations in inhibition efficiencies mainly depend on the type and nature of the inhibitors. Polarization and ac impedance measurements carried out at different concentrations of studied Schiff bases revealed that these compounds are adsorbed on copper surface and the adsorption obeys Langmuir adsorption isotherm. From the adsorption isotherms, the values of equilibrium constant, Kads, and the free energies of adsorption, ΔGads, were calculated. The associated activation energy of corrosion and other thermodynamic parameters such as enthalpies and entropies have also been determined.

Practical implications

The presence of high efficiency and low cost inhibitors is essential in acid pickling treatments for protection of copper and lowering of acid consumption. In comparison with conventional copper corrosion inhibitors such as benzotriazole, this result would be considered as a step forward in determination of new corrosion inhibitor.

Originality/value

This paper reveals that Schiff bases can be successfully used for protection of copper surface in acid pickling solutions.

Abstract

Purpose

In this paper, the main aim is to study the synergistic effects of alkanethiols upon inhibition of Schiff bases, N,N′‐ethylen‐bis and N,N′‐ortho‐phenylen‐bis in 0.5 M sulphuric acid solutions.

Design/methodology/approach

Measurements were carried out in a three‐electrode cell assembly connected to the corrosion measurement system using software for Tafel polarization. Impedance measurements were carried out at open circuit potential using an electrochemical interface and frequency response analyzer at frequencies from 100 kHz to 10 MHz.

Findings

Results obtained revealed that at high concentrations, each of the investigated Schiff bases and 1‐dodecanethiol (DT) were good inhibitors when added separately to the corrosive media. The decrease in corrosion rate was associated with an increase in their concentrations. It was found that the presence of DT together with Schiff bases in corrosive medium increased inhibition effect, especially at low concentrations. Synergistic effect is discussed from viewpoint of their co‐adsorption. The adsorption of combined inhibitors was found to follow Langmuir isotherm. Thermodynamic calculations revealed that adsorption of combined inhibitors had a physical nature.

Research limitations/implications

In order to improve further the performance of Schiff bases and identifying their synergistic effects with other additives it is suggested that some more researches on other Schiff bases with other alkanethiol molecules must be done.

Practical implications

The results of this paper can be used for acid cleaning of carbon steel in which suitable inhibitor systems with the highest efficiency is required.

Originality/value

This paper reveals that the presence of DT molecules in solution encourage the adsorption of Schiff bases by facilitating the electrostatic co‐adsorption of Schiff base molecules through a synergistic effect.
