Empirical Studies in Financial Accounting

Abstract The purpose of this study is to investigate the relationship between financial report readability and stock return synchronicity with the moderating role of institutional ownership and information asymmetry in companies listed in the Tehran Stock Exchange (TSE). This research is in terms of its purpose. Its period is from 2015 to 2019, and the selected sample consists of 171 companies listed in TSE. To test the research hypotheses through panel data, the ordinary least squares regression method in Eviews software was used. The findings of the research hypothesis test show that there is a negative and significant relationship between financial report readability and the stock return synchronicity. Also, institutional ownership as a moderating variable negatively correlates the illusion of financial report readability and the synchronization of stock prices. Additionally, the moderating effect of the information asymmetric variables on the relationship between the financial report readability and the price synchronization is positive and significant. 
According to the findings, on the one hand, it is necessary to examine the implications of financial report readability. On the other hand, in order to improve the market, more attention needs to be paid to the issues affecting the stock return synchronicity.

Abstract Today, with rapid and sustained changes in business markets, a growing number of companies have turned diversification into new product segments or global markets by shifting their business to increase the importance of long-term financial viability and sustainability. Moreover, increasing the variety of products, covering the uncertain demand of customers, managing inventories and timely action have been important issues in manufacturing companies. Accordingly, the main purpose of this study is to investigate the impact of diversification strategy on inventory performance, which is one of the topics of operations management by considering the classification of the diversity into related, unrelated and international. The statistical population studied includes all companies listed in the Tehran Stock Exchange during the years 2009-2018. Sampling has been done by screening method, and the number of companies in the final sample has reached 120 companies. The hypotheses have been tested by the estimated generalized least squares method. The results show that related and international diversification have positive and significant effects on inventory performance. The findings also indicate that unrelated diversification has an adverse effect on inventory performance, but this relationship is not statistically significant. Based on the acquired results, an increase in related and international variety of products, relying on higher safety stock, has led to an increase in sales. In addition, the insignificancy in the effect of unrelated diversification on inventory performance can be attributed to production costs and marketing programs of manufactured products.

Abstract In this study, we examine the market reaction to the asset revaluation of listed companies. We first estimate the market reaction to the asset revaluation announcement, then explore potential explanations for the market reaction. Asset revaluation can improve firm's access to financing by improving financial ratios. On the other hand, the increase in the firm's capital from the revaluation is accompanied by stock split which results in a decrease in the theoretical share price. This apparent drop in theoretical share prices could induce shareholders' interest as a result of money illusion. To assess these alternative explanations, we run a cross-sectional regression of the cumulative abnormal return on proxies of each factor. To further explore the driver of market reaction, we examine whether firms that have re-evaluated their assets could improve their access to financing or reduce their financing costs. For this purpose, we study a panel of listed companies between 2011 and 2019 for their access to finance, financing cost, investment, and financial leverage, controlling for the firm and year fixed effects. Our results are more consistent with the nominal price reductions causing the market reaction. We do not find evidence of asset revaluations leading to the firm's better access to financing.

Abstract The risk of stock price crash is one of the topics of interest in capital market research. Since the main mission of capital market regulators is to protect the rights of investors, it has always been important to consider the factors that affect crash risk. The quality of financial reporting and earnings management patterns are the most important tools available to regulators that can help them manage crash risk aversion, which is why this study addressed them. Earning management patterns include earnings management through accruals and real earnings management. The statistical population of this study is the companies listed on the Tehran Stock Exchange and the research sample was selected in terms of some features (including 167 companies) for the period 2012 to 2018. The research method of the present study is descriptive- correlation and the research hypotheses are tested using the generalized least squares method. The results show that the accrued earnings management model is related to stock crash risk and the use of earnings management through accruals increases the risk of stock price falls. While this is not the case with earnings management through real activities, the application of this earnings management model has nothing to do with the negative changes in stock returns. In addition, audit quality weakens the relationship between accrued earnings management pattern and stock crash risk. While the relationship between real earnings management pattern and stock crash risk is not affected by audit quality

Abstract One of the problems that many organizations have is changing the behavior of the employees of that organization. Leaving the state of behavioral balance can be considered as human behavioral entropy that can no longer comment on his behavior. Understanding the causes of these behaviors can prevent many problems in organizations. The purpose of this study is to develop a model of auditors' behavioral entropy.. The present study was conducted in the framework of a qualitative approach and using the data research method of the foundation in 2019. Data collection tools were semi-structured interviews and in order to collect information, using purposive sampling method with 29 auditors of the auditing organization and managers of the auditing organization, 15 of whom were members of the community. And 14 of them were other auditors, familiar with the concept of behavioral entropy. In Tehran, interviews were conducted using the snowball method. . Data analysis was performed in three stages of open coding, axial coding and selective coding. Based on that, a qualitative research model was designed. In this model, the most important causal factors included the economic characteristics of the country, the auditor's financial condition, individual and family characteristics, educational and experimental characteristics. Based on that, a qualitative research model was designed. In this model, the most important causal factors, including the economic characteristics of the country, are the audited financial conditions. The underlying context also includes the control system, commitment to professional use, and professional budgeting
