چکیده

 هدف از این پژوهش، بررسی انحراف مقطعی در عدم تقارن زمانی جریان نقد و تأثیر آن بر محافظه­کاری شرطی است. در این پژوهش با استفاده از داده‌های 120 شرکت پذیرفته‎شده در بورس اوراق بهادار تهران در سال‌های 1384 تا 1390، به بررسی این موضوع پرداخته شد. الگوی رگرسیون پژوهش با استفاده از روش داده‌های تابلویی با رویکرد اثرهای ثابت، بررسی و آزمون شد. متداول­ترین معیار محافظه­کاری شرطی در حسابداری، عدم تقارن زمانی در شناسایی سودها و زیان­ها است. این معیار، ترکیبی از عدم تقارن زمانی اقلام تعهدی و جریان­های نقد عملیاتی است. با توجه به اینکه عدم تقارن جریان­های نقد عملیاتی به دامنۀ شناسایی سودها و زیان­ها تعلق ندارد، موجب انحراف در آزمون محافظه­کاری می‎شود. در این پژوهش با توجه به اخبار بد و خوب، نشان داده شد عدم تقارن جریان­های نقد عملیاتی به‎طور مقطعی با متغیرهای چرخۀ عمر شرکت (اندازه، عمر، رشد و مخارج سرمایه­ای) تفاوت دارد. نتایج نشان می­دهد در مراحل اولیۀ چرخۀ عمر شرکت، محافظه­کاری بیشتر است.

چکیده [English]

The current study aims to review the cross sectional variation in cash flow asymmetric timeliness and its effect on conditional conservatism. In this study, data from 120 firms in Tehran Stock Exchange for the period spanning 1384- 1390 were examined. The regression model used in this research is panel data method with fixed effects approach. The most common measure of conditional conservatism in accounting is asymmetry timeliness in recognizing profits and losses. Nevertheless, this measure combines both asymmetry timeliness of accruals and cash flows from operation. Given that asymmetry timeliness of operating cash flow does not belong to the domain of profits and losses, it causes variation in the test of conservative. In this research, with respect to good and bad news, it was shown that asymmetry timeliness of operating cash flow is cross sectionally  different with lifecycle variable of company (size, age, growth and capital expenditure). The results show that conservatism is higher in the early stages of the company lifecycle.
