چکیده
هدف پژوهش حاضر، بررسی تأثیر معیارهای عدم اطمینان اقتصادی بر رابطه بین قابلیت مقایسه صورتهای مالی و خطر سقوط قیمت سهام در بورس اوراق بهادار تهران است. برای اندازهگیری ریسک سقوط قیمت سهام از معیار چولگی منفی بازده سهام و برای اندازهگیری عدم اطمینان اقتصادی از سه شاخص تغییرات نرخ تورم، تغییرات نرخ ارز و تغییرات نرخ رشد اقتصادی استفاده شده است. بدین منظور دادههای مربوط به 119 شرکت پذیرفته شده در بورس اوراق بهادار تهران برای دوره زمانی بین سالهای 1392 تا 1398 مورد تجزیهوتحلیل قرار گرفته است. الگوی رگرسیون پژوهش با استفاده از روش دادههای تابلویی با رویکرد اثرات تصادفی، بررسی و آزمون شده است. نتایج نشان داد در شرایط عدم اطمینان اقتصادی، خطر سقوط قیمت سهام افزایشیافته و معیارهای عدم اطمینان اقتصادی رابطه منفی بین قابلیت مقایسه صورتهای مالی و خطر سقوط قیمت سهام را تعدیل میکنند. علاوه بر این، نتایج پژوهش نشان داد که ارتقاء ویژگی کیفی قابلیت مقایسه در صورتهای مالی باعث تسهیل دسترسی سرمایهگذاران به برخی اطلاعات افشاء نشده توسط مدیران شرکتها میشود و ازاینرو انگیزه مدیران جهت انباشت اخبار بد کاهشیافته و در نتیجه ریسک سقوط قیمت سهام در اثر انتشار ناگهانی اخبار بد مخفی شده کاهش مییابد.
