Document Summary

Agriculture at the level of the farm is the most highly competitive sector in the. Most agricultural commodities exhibit the four requirements for a competitive market: identical products, good information about prices, a large number of farms, and free flow of resources into and out of the industry. Domestic demand: the demand for agricultural products is highly price and income inelastic, the market demand curve is extremely steep (price inelastic) and shifts out slowly over time (income inelastic) The supply of most agricultural commodities has three characteristics of note: Short-run instability: weather dependent, (1) increasing price elasticity over time, (2) substantial advances in productivity over time, (3) considerable instability in the short run. Long run price behavior: over the long run, prices of agricultural products have fallen relative to, agriculture follows long run price trends by means of a concept called prices generally parity. Parity = output prices received by farmers.
