A new method for assessing the marketing efficiency of agricultural marketing channels by Arif Abad, Mohd Abdul Muqeet Maaz, Mohd Salman Shamsi

“…The proposed method has two parts: (1) the ratio of overall channel benefit to cost, excluding consumers, to avoid misleading results, indicating higher benefits for channel members; (2) the ratio of the net price received by farmers to the price paid by consumers, reflecting farmer earnings. By separating marketing margins and costs, the proposed method simplifies previous complexities. …”
