This study examines empirically the effect of equity overvaluation on future stock price crash risk in companies with greater information asymmetry. Using the information asymmetry and crash risk indicators, the question that whether overvalued firms are more prone to future crash risk is investigated. Accordingly, the first purpose of this study is to investigate the relation between overvaluation and the future stock price crash risk. With the increase of information asymmetry between a firm and the market, managers have more abilities and opportunities to withhold bad news and accelerating the release of good news. As a result, it is expected that the information asymmetry between managers and investors increases future stock price crash risk. In so doing, we identify one main hypothesis and three subsidiary ones and the data of 111 listed companies of Tehran Stock Exchange for the period between 2009 and 2017 were analyzed and A panel data approach has been used to test of research hypotheses. According to the results, there is a positive and significant relationship between the overvaluation and the future stock price crash risk of companies which are operating in monopolistic markets and this relation intensified by the information asymmetry.

Sports tourism is one of the most attractive types of tourism that occurs in different regions and countries. This  tourism type is effective in economic fields and extremely significant in cultural and sportsmanship contexts.  To this end, the current research aimed to identify and explain the effective components of sport tourism in the  sublimity of culture and sportsmanship, conducted through a mixed method. This research approach was  sequential exploratory in two qualitative-quantitative phases, in which “thematic analysis” and “survey”  methods were used, respectively. The first phase’s statistical population included experts in sport tourism, sport  management, culture management, and sportsmanship, with 14 individuals participating in semi-structured  interviews using a purposive sampling method. After determining the effective actors in this field, 32 experts  responded to questionnaires using a systematic sampling method in the study’s second phase. According to the  research findings of the first phase, the themes extracted from the semi-structured interviews comprised 39  fundamental themes, 15 organizing themes, and four global themes. Per the second phase of the study’s  findings, all themes were approved by the experts, all determinants of the role of sport tourism in the sublimity  of sports culture and sportsmanship. As a result, sports tourism, while creating macroeconomic benefits for  residents and visitors, significantly contributes to the sublimity of sports culture and sportsmanship, where this  category can strengthen the value and ethical attitudes in addition to creating recreational experiences

Given the significance of auditor quality and its impact on the quality and reliability of financial statements, studies on auditor quality are essential. One factor that affects audit quality apart from auditor selection and changes is the internal control system. This study examines the relationship between managerial stock ownership, internal control weaknesses, auditor rotation, and audit quality in the context of Iranian listed companies. A sample of 810 observations was selected using a screening method. The study covers the period from 2016 to 2021. Multiple regression analysis was employed as the statistical method for hypothesis testing. The findings reveal that when managers posses a relatively low (high) level of managerial stock ownership, an increase in internal control weaknesses leads to the selection of lower (higher) quality auditors. Furthermore, the results demonstrate that under conditions where managers hold a relatively low (high) proportion of company shares, an increase in internal control weaknesses results in a decrease (increase) in auditor rotation. These findings shed light on the importance of managerial stock ownership between internal control weaknesses, auditor rotation, and audit quality. The study contributes to the existing literature on corporate governance, internal control systems, and audit practices, providing valuable insights for regulators, auditors, and managers in an emerging business environment.
