Demand and Substitution of Agricultural Inputs in the Central Corn Belt States

No 157040, Technical Bulletins from United States Department of Agriculture, Economic Research Service

Abstract: This study estimates shortrun and longrun elasticities for agricultural inputs, along with elasticities of substitution, using a theoretically consistent restricted profit function and a series of decomposition equations. The model is also disaggregated on the input side, uses a flexible functional form, incorporates the effect of agricultural policies, and introduces a weather index. The methodology is applied to the central Com Belt States and is used to calculate the effect of market-oriented policies to reduce chemical input use. The study finds that producers' responsiveness to price changes of fertilizer and pesticides is very small in the short run and moderate in the long run. Ad valorem taxes would have negligible shortrun and small longrun effects on chemical input use while restructuring Federal programs appears to be effective in the long run.
