The document discusses the price spread between what consumers pay and what farmers receive for agricultural products. It notes several difficulties in accurately measuring and comparing prices at different stages of marketing. The producer's price is defined as the net price the farmer receives at first sale, which is the wholesale price minus marketing costs incurred by the farmer. Factors that affect marketing costs include perishability, storage needs, volume handled, packaging, grading, advertising, bulkiness, retail needs, storage needs, risk, and dealer facilities provided. Marketing costs are generally higher for agricultural products than manufactured goods due to dispersed farms, small outputs, bulkiness, grading challenges, irregular supply, storage and processing needs, multiple middlemen, and risk.
