Abstract

This research estimates the translog cost function for a sample of Islamic and traditional banks. Economies of scale, economies of scope, elasticity of substitution and own-price elasticity of inputs is also estimated and compared for these banks. The significant result of this research is that Islamic banks cost function reveals economies of scale until assets reach $556 million, while that of traditional banks shows diseconomies of scale. The economies of scale for the Islamic banks provide an advantage to reduce average cost as these banks expand production and operations. This advantage permits Islamic banks to compete with the traditional banks to get a bigger share of the market. As for economies of scope, the Islamic banks Cost function was not characterized by cost complementarity. This implies that each Islamic bank should specialize in one type of contract since each contract requires different mixture of inputs. يتم في هذا البحث تقدير دالة التكاليف المتسامية اللوغاريتمية لعدد من البنوك الإسلامية والتقليدية لقياس وفورات الحجم ووفورات النطاق، ومرونات الإحلال، والمرونات السعرية للمدخلات في تلك البنوك، ومقارنتها فيما بينها، واستخلاص نتائجها الاقتصادية. وأهم نتائج البحث هي أن البنوك الإسلامية تتمتع بوفورات حجم موجبة بينما تتمتع أغلب البنوك التقليدية بوفورات حجم سالبة. هذه الوفورات الموجبة تعطي البنوك الإسلامية ميزة في خفض متوسط تكلفتها الكلية كلما توسعت في أعمالها وخدماتها المصرفية، إلى أن يصل إجمالي أصول البنك إلى نحو 556 مليون دولار، مما يتيح لها حتى ذلك الحجم زيادة قدرتها على منافسة البنوك التقليدية، والاستحواذ على حصة أكبر من السوق. كذلك أظهرت النتائج أن البنوك الإسلامية لا تتميز بتكاليف تكاملية (أي تنعدم فيها وفورات النطاق)، وأن من الأفضل لها من جهة التكاليف أن تتخصص في نوع معين من العقود، لأن كل عقد يتطلب مزيجًا مختلفًا من المدخلات.
