چکیده مقاله :
پژوهش حاضر به بررسی تاثیر عدم اطمینان اقتصادی بر نقدشوندگی سهام با تاکید بر دوره تصدی مدبر عامل پرداخته است. این پژوهش از لحاظ هدف، کاربردی بوده و از بعد روش شناسی همبستگی از نوع علّی (پس رویدادی) میباشد. جامعه آماری پژوهش شرکت های پذیرفته شده در بورس اوراق بهادار تهران بوده و با استفاده از روش نمونه گیری حذف سیستماتیک، 124 شرکت به عنوان نمونه پژوهش انتخاب شده بین سالهای 1392 تا 1399 مورد بررسی قرار گرفته است. در این پژوهش برای عدم اطمینان اقتصادی از متغیرهای کلان اقتصادی شامل تغییرات نرخ تورم، نرخ بهره، نرخ ارز و تولید ناخالص داخلی استفاده شده است. همچنین برای بررسی نااطمینانی از روش مدل های ناهمسانی واریانس شرطی خودرگرسیونی (ARCH) وخود رگرسیونی تعمیم یافته (GARCH) استفاده شده است. نهایتا با استفاده از الگوی داده های تابلویی و به کمک رگرسیون چندمتغیره، به بررسی فرضیه های تحقیق پرداخته شده و با توجه به نتایج آزمون فروض کلاسیک مبنی بر ناهمسانی واریانس از روش حداقل مربعات تعمیم (GLS) یافته استفاده شده است. نتایج حاصل از پژوهش نشان میدهد که عدم اطمینان اقتصادی بر نقدشوندگی سهام تاثیر معنی دار دارد. اثرات تعاملی دوره تصدی مدیر عامل به همراه تغییرات نرخ تورم، نرخ بهره، بر نقد شوندگی سهام معکوس و معنی دار بوده ولی برای تغییرات رشد اقتصادی و نرخ ارز مثبت و معنی دار می باشد.
In the current study, the impact of economic uncertainty on stock liquidity has been investigated with an emphasis on CEO tenure. This research is practical in purpose, and from a correlation methodological perspective, it is causal (post-event). The research population consists of companies admitted to the Tehran Stock Exchange. A systematic elimination sampling method has been used to select 124 companies from 2012 to 2019. In this research, macroeconomic variables, including changes in the inflation rate, interest rate, exchange rate and gross domestic product (GDP), have been used to assess economic uncertainty. Furthermore, both autoregressive conditional heteroscedasticity (ARCH) and generalized autoregressive conditional heteroscedasticity (GARCH) models have been employed to investigate uncertainty. Finally, by using the panel data model and multivariate regression, research hypotheses have been investigated. According to the results of the classical hypothesis test based on variance heterogeneity, the generalized least squares (GLS) method has been utilized. According to research findings, economic uncertainty has a substantial impact on stock liquidity. The interactive effects of CEO tenure along with changes in inflation and interest rates on stock liquidity are inverse and significant. For economic growth and exchange rate changes, however, they are positive and significant. .
