چکیده

بهره در الگوهای اقتصادی متعارف عاملی کلیدی و تنظیم کننده است. اما بحث‌های فراوانی در رد یا تایید بهره پولی با تمسک به ریشه­های آن وجود دارد. برخی از این ریشه­ها، عینی هستند مانند مولدیت سرمایه و جمیعت و برخی مانند رجحان زمانی، رجحان نقدینگی و تقعر تابع مطلوبیت، ذهنی هستند. این مقاله با رویکردی انتقادی به نظرات موافق، تلاش خود را بر الگوسازی یک اقتصاد بدون بهره پولی معطوف می‌نماید. دستاورد اصلی این مقاله تدوین یک مدل اقتصادی بدون بهره پولی، با استفاده از یک الگوی نسل­های تداخلی سه دوره­ای است. سوال­های مقاله این است که آیا یک اقتصاد بدون بهره می‌تواند کارکردهای اقتصادهای بهره‌ای مانند رشد، مصرف، پس‌انداز و تشکیل سرمایه را داشته باشد؟ آیا چنین اقتصادی به تعادل خواهد رسید؟ و آیا چنین تعادلی پایدار خواهد بود؟ در این مدل پول فقط یکبار توسط دولت منتشر می‌شود. در نتیجه به دلیل رشد اقتصاد و عدم انتشار مجدد پول، نوعی تورم منفی در اقتصاد رخ خواهد داد و نتیجه گرفته می‌شود ادامه حیات اقتصاد، ارزش واقعی واحدهای پولی ثابت را افزایش می‌دهد. رجحان نقدینگی در این الگو از بین می‌رود، در نتیجه کنز پول وجود نخواهد داشت و تخصیص­ها بهینه بوده و این بهینگی پایدار نیز خواهد بود.

چکیده [English]

Interest in conventional economic models is a key and regulator factor. However, there are many debates on the rejection or confirmation of monetary interest rate based on its origins. Some of these origins are objective, such as the productivity of capital and the population, and some like the time preference, the liquidity preference, and the convergence of the utility function, are subjective. This study, in considering the critical views of monetary interest rate, offers a model that, while eliminating interest rate, seeks to exploit the benefits of interest economies, such as consumption, savings and accumulation of capital. The intergenerational exchange is shaped in the framework of the overlapping generation model and the population is a positive factor that grows as production grows.  In this model, money is issued only once by government and it is concluded that the continuation of the economy will increase the real value of fixed currency units. The liquidity preference will be eliminated in this model, and as a result there will not be Hording money, and the allocations will be optimal, and this optimality will be permanent.
