چکیده
در این مقاله با بررسی اجمالی لزوم توجه به جنبش‌های هستی‌شناسی و معرفت‌شناسی در علوم و علم‌گرایی در مالی، ابتدا به بیان پاردایم‌های مالی پرداخته می‌شود. سپس با تبیین علم اثباتی و هنجاری، مقایسه مفاهیم آن دو در کنار تعبیر سودمندی در کاربرد مدل‌ها در مالی مورد توجه است. هم‌چنین، در بیان فاصله با علم موضوع استفاده از ابزار و هنر در مالی مطرح می‌شود. در ادامه نقد اثبات‌گرایی مالی در بیان تشابهی میان خردگرایی و ابزارگرایی توضیح داده می‌شود. نطریاتی که پارادیم‌های اصلی در مالی است و ضعف آن‌ها بیان می‌شود. در آخر نیز به اثباتی یا هنجاری بودن مدل‌های مالی با توجه به تاثیرات نحوۀ تعامل با داده مورد بررسی قرار می‌گیرد. ضمن آن‌که، مشکل ترجمه در مدل از زبان معمولی به زبان رسمی و نظری وجود دارد، که به دلیل عدم‌امکان مرزبندی میان پدیده‌های منطقی و غیرمنطقی است. در نهایت، به معرفت‌شناسی در استفاده از مدل‌ها در مالی به جای رویکردی صرفاً علمی اثباتی توجه می‌شود.

چکیده English

In this article, with an overview of the need to pay attention to the ontological and epistemological movements in science and scientism in finance. First, the financial paradigms are described. Then, by explaining positive and normative science, the comparison of their concepts along with the useful interpretation in the application of models in finance is considered. Also, in expressing the distance with science, the issue of using instruments and art in finance is raised. The following is a critique of financial positivism in a statement expressing the similarities between rationalism and instrumentalism. Theories that are the main paradigms in finance and their weaknesses are explicated Finally, the positive or normative nature of financial models is examined with respect to the effects of how they interact with data. At the same time, there is a problem of translation in the model from common language to formal and theoretical language, which is due to the impossibility of demarcating between logical and irrational phenomena. Therefore, epistemology is considered in the use of models in finance instead of a purely positive science approach.
