This document discusses how technological innovations in agriculture impact supply and prices. It provides examples of major advancements like mechanization, fertilizers, and biotechnology. Technology allows farmers to increase supply by producing more with the same inputs. While demand for food is inelastic, supply becomes more elastic over time. New technologies can initially increase total revenue but eventually farmers must adopt them to remain competitive, trapping them on a "technological treadmill" where profits decline. Emerging biotechnologies may change agricultural marketing systems and create opportunities for new crop types.
