Major inputs are the national agricultural <br />productivity measures and resource availability. <br />Constant Price Demand - provides information on shifts in demand, by <br />endogenous factors which move the entire demand curves for agricultural <br />products by aggregating the shifts in demand created by population, income <br />and taste factors for this component for commodities in (1) human consump- <br />tion, (2) livestock feed, and (3) international trade, and (4) other use. <br /> <br />Aggregate Farm Output - uses the aggregate demand and supply shifters and <br />the U.S. inflation rate to determine prices received and paid by farmers, <br />quantity of agricultural products marketed, and gross and net farm income. <br />Commodity Production and Util ization - uses the base prices of 23 commod- <br />ities and the constant price supply and demand for each commodity from <br />these two components in the system. It detennines the equil ibrium price <br />and quantity for each commodity. <br />Land Use and Regional Shares of Production - disaggregates the production <br />of the individual commodities from the Commodity Production and Utilization <br />component to the various regions or states of the U. S. Total amount of <br />cropland required is determined. <br /> <br />These components and the assumptions for the NIRAP High Plains Base- <br />line run are described in detail below. Because the Constant Price Supply <br />and Constant Price Demand components provide basic information to the other <br />components, those will be discussed first. <br /> <br />II-6 <br />
