This document discusses price spread and marketing efficiency in agricultural markets. It defines price spread as the difference between the consumer price and the net price received by producers, expressed as a percentage of the consumer price. Price spread includes marketing costs to move products from production to consumption points as well as profits for intermediaries. Marketing efficiency is the ratio of market outputs to inputs and indicates how well a market achieves its objectives with minimum costs. The document outlines approaches to measure price spread and marketing efficiency, and notes that price spread is inversely related to marketing efficiency - as efficiency increases, price spread decreases.
