Purpose: The purpose of this paper is to examine the effect of financial distress costs, corporate growth rate, and flexibility on the interaction between ownership structure and corporate debt policy.Design/methodology/approach: The authors test the hypotheses by employing simultaneous equations system methodology with two-stage least squares regression and panel data technics on a sample of 786 listed companies on the Tehran Stock Exchange during 2010-2015.Findings: The results indicate that there is a positive and significant relationship between corporate debt level and managerial ownership in the Iranian listed companies. The authors also find no convincing evidence that either the firm’s growth or financial health could influence or moderate this interrelationship.Research limitations/implications: The implications drawn from this study are constrained by two primary limitations. First, the present study is conducted in an Iranian setting; therefore, the data utilized for the study only contain companies listed on the Tehran Stock Exchange. The utilization of listed companies on the Tehran Stock exchange is likely to affect the generalizability of the study in a national context. Second, the authors were unable to extend the sample time period due to some major deficiencies in the Tehran Stock Exchange library and its supplementary software.Social implications: Since the fundamental institutional assumptions underpinning the western and even East Asia capital structure models are not valid in the institutional environment of Iran, the findings could provide substantial implications for our understanding of capital structures as well as debt policy literature.Originality/value: This is an innovative research in terms of the mutual relationship between debt and ownership structure and the use of equations system to measure the interaction between them.

Purpose: The purpose of this paper is to examine the effect of earnings quality (as a proxy for financial reporting quality) of companies listed on the Tehran Stock Exchange (TSE) and the quality of their financial information disclosure on stock returns. Design/methodology/approach: The authors test the hypotheses by conducting panel data analysis on a sample of 1,680 firm-year observations from companies listed on the TSE during 2009-2014. The authors also conduct the variance inflation factor and unit root tests to control for the severity of multicollinearity in their ordinary least squares regression analysis and whether the time series variables are non-stationary and possess a unit root. Findings: Using Francis et al. (2005) and modified Jones (1991) models as measures for earnings quality, the results are indicative of a significant and positive relationship between firms’ earnings quality and their stock returns. However, the research findings suggest that earnings management as well as disclosure quality (DQ) is not significantly associated with firms’ stock return. Research limitations/implications: Although the authors controlled for some of the factors affecting stock returns, there are still some other factors such as the operating environment, institutional setting and/or information uncertainty that could influence stock returns, and accordingly, the authors were not able to exclude their possibility and get the most robust results. Moreover, there are several models proposed in different studies for measuring earnings quality which have led to mixed results particularly without a general consensus on what a good model is, and whether earnings quality is a priced risk factor. Originality/value: Taken as a whole, the paper could provide new insights into the determinants of stock returns which has rarely been considered by prior finance literature. Furthermore, the unique institutional context of the paper could contribute substantially to the literature on the relationship between financial reporting and DQ and stock returns.

Purpose: The aim of this study is to examine the effect of financial leverage impact on customer satisfaction and marketing costs including research and development (R&D) and advertisement costs. Furthermore, the authors aim to investigate whether customer satisfaction as well as financial distress moderates the effect of financial leverage impact on customer satisfaction and marketing costs including R&D and advertisement costs.Design/methodology/approach: The statistical population of this study consists of listed companies on the Tehran Stock Exchange manually obtained from different industries in 2017. Multivariate regression based on data compilation methodology is used to test research hypotheses.Findings: The results indicate that financial leverage is negatively and significantly associated with customer satisfaction and this negative relationship is more pronounced in companies with lower sale growth. Furthermore, the authors' results suggest that customer satisfaction negatively (positively) and significantly affects firm value in companies with lower (higher)-financial leverage. The authors also demonstrate that there is no significant relationship between financial leverage caused by financial flexibility and firm value caused by customer's satisfaction (CS). The authors' findings also suggest that financial distress significantly affects the relationship between financial leverage and customer satisfaction. Finally, the authors' find that financial leverage significantly affects firms' R&D and advertisement costs.Research limitations/implications: Since the fundamental institutional assumptions underpinning the Western and even East Asia financial models are not valid in the institutional environment of Iran, the authors' findings could provide substantial implications for the authors' understanding of the relationship between finance and R&D costs and contribute substantially to customer satisfaction and firm value literature as well. The sample country of the present paper has recently experienced a spate of financial collapses that somewhat contributes, indirectly, to financial distress incurred by the Iranian firms. Moreover, R&D costs are growing among the Iranian quoted firms.Originality/value: Since the fundamental institutional assumptions underpinning the Western and even East Asia financial models are not valid in the institutional environment of Iran, the authors' findings could provide substantial implications for our understanding of the relationship between finance and R&D costs and contribute substantially to customer satisfaction and firm value literature as well. The sample country of the present paper has recently experienced a spate of financial collapses that somewhat contributes, indirectly, to financial distress incurred by the Iranian firms. Moreover, R&D costs are growing among the Iranian quoted firms.

Purpose: The purpose of this paper is to establish a linkage between two rarely researched areas, i.e. earnings quality (EQ) and access to external and internal debt financing. Specifically, the authors aim to examine whether the quality of a firm’s reported earnings is significantly associated with its access to both private and bank debt financing. Design/methodology/approach: The authors test the hypotheses by employing panel data analysis for a sample of 108 companies listed on the Tehran Stock Exchange (TSE) during 2006-2015. The tests were conducted by using R econometric software. Findings: After controlling for some firm-specific factors and consistent with the primary expectations, the results reveal a significant and positive relationship between EQ and managerial access to external (bank) debt financing. In addition, the findings indicate that EQ is negatively associated with internal debt financing which is measured as the changes in firm retained earnings. Research limitations/implications: Although the authors cautiously conducted the present study, there are some limitations that merit further consideration. First, the authors collected the data manually from 14 categories of industries in the TSE and, accordingly, an aggregate analysis across multiple categories of industries might have missed industry-specific and unique issues. Second, the authors used a narrow conceptualization of accruals quality which merely assesses a firm’s EQ. The measures can be enhanced by including more actionable proxies. Third, since the data on debt financing were collected from two different sources, this might have caused common method variance in the results procedurally. Originality/value: Since the fundamental institutional assumptions underpinning the Western and even East Asia debt contracting and EQ models are not valid in the institutional environment of Iran, the findings could provide substantial implications for the understanding of both debt financing and the quality of earnings. These significant institutional and ownership differences are the factors affecting firms’ leverage and capital choice decisions. Indeed, the study has laid some groundwork upon which a more detailed evaluation of the Iranian firms’ financial structure could be based.

Purpose: The present study seeks to shed further light on the effectiveness of Basu (1997) and Khan and Watts' (2009) differential timeliness metrics in detecting predictable differences in conservatism following corrections of restated earnings.Design/methodology/approach: Using cross-sectional and time-series analyses for companies listed on the Tehran Stock Exchange during 2009–2013, the results indicate lower conservatism for restating firms as compared to their counterparts during prerestatement period.Findings: Using cross-sectional and time-series analyses for companies listed on the Tehran Stock Exchange during 2009–2013, the results indicate lower conservatism for restating firms as compared to their counterparts during prerestatement period. In contrast, our findings are indicative of higher conservatism among these restating firms during the years of restatements. Moreover, the time-series approach captures a higher conservatism for the restating firms during restatement years than prerestatement periods. Overall, these results provide insight into the usefulness of the metrics used in the restatement setting.Originality/value: Similar to recent papers, the present study seeks to shed further light on the ability of Basu-based coupled with Khan–Watts-based measures of conservatism to detect situations in which companies' earnings are known to be significantly restated.

The aim of this paper is to provide empirical evidence for the impact of abnormal audit fees on future restatements. We examine whether firms that restate their financial statements have higher levels of total audit fees than their counterparts. In this regard, the authors test their hypothesis by performing panel data analysis on a sample of 936 firm-year observations from companies listed on the Tehran Stock Exchange during 2009-2014. We find that there is a negative relationship between the two; specifically, abnormal audit fees are lower in the periods leading up to the occurrence or announcement of the restatement (i.e., the next fiscal year).
