Abstract    In this paper, the Bertrand's price competition in the retail duopoly with asymmetric costs is analyzed. Retailers sell substitute products in the framework of the classical economic order quantity (EOQ) model with linear demand function. The market potential and competitor price are considered to be the bifurcation parameters of retailers. Levels of the barriers to market penetration depending on the bifurcation parameters are analyzed. The conditions of Bertrand-Nash equilibrium in parametric and trigonometric forms are found.


Keywords    EOQ model, retail duopoly model, Bertrand equilibrium, market potential, bifurcation parameter, return on logistics costs, barrier to entry


چکیده    در این مقاله، رقابت قیمت برتراند در انحصار خرده فروشی با هزینه های نامتقارن مورد تحلیل قرار گرفت. خرده فروشان محصولات جایگزین را در چارچوب مدل EOQ کلاسیک با تابع تقاضای خطی می فروشند. پتانسیل بازار و قیمت رقیب پارامترهای انشعاب از خرده فروشان در نظر گرفته می شود. سطوح موانع نفوذ در بازار بسته به پارامترهای انشعاب تجزیه و تحلیل می شوند. شرایط تعادل برتراند-نش در اشکال پارامتری و مثلثاتی یافت می شوند.
