چکیده

این پژوهش در پی پاسخ به این سؤال است که آیا اقلام تعهدی اختیاری به‎عنوان جانشین مدیریت سود تعهدی بر رابطۀ مدیریت سود واقعی و هزینۀ سرمایه تأثیرگذار است؟ در این پژوهش مدیریت سود تعهدی بر مبنای مدل کازنیک و مدیریت واقعی سود از طریق جریان نقدی غیرعادی، تولید غیرعادی و هزینه‌های اختیاری غیرعادی سنجیده شده است. نتایج برآورد رابطۀ فرضیه‌های پژوهش با بهره‎مندی از روش داده‌های ترکیبی برای 121 شرکت بورس اوراق بهادار تهران طی دورۀ پنج‎ساله (1388 تا 1392) حاکی از این است که بین هر یک از معیارهای مدیریت سود واقعی و هزینۀ سرمایه، رابطۀ مثبت معناداری وجود دارد. همچنین یافته‌ها نشان می‌دهد مدیریت سود واقعی نه‎تنها به‎صورت مستقیم، بلکه به‎طور غیرمستقیم و از طریق مدیریت سود تعهدی (میانجی‌گر کامل) بر هزینۀ سرمایه اثر می‎گذارد. به بیان دیگر مدیریت سود واقعی، مدیریت سود تعهدی را بالا می‎برد و مدیریت سود تعهدی موجب افزایش هزینۀ سرمایه می‌شود.

چکیده [English]

This study investigates mediating role of accrual-based earnings management on the relationship between real earnings management (abnormal cash flow operating, abnormal production and abnormal discretionary expenses) and Cost of capital. We measured accrual-based earnings management through Kasznik Model and real earnings management by abnormal profits through cash flow, producing unusual and abnormal discretionary expenses. Using a combination of technical data for the 121 companies in Tehran Stock Exchange during the 5 year period 2009 to 2013, results of this study show that real earnings management is positively associated with cost of equity. In addition, findings show that real earnings management not only was directly related to cost of capital, but also indirectly associated with the cost of capital through an accrual earnings management. In other words, real earnings management causes rising accrual-based earnings management, and accrual-based earnings management will increase cost of capital.
