Crop-Water Production Functions

[1] Metaregression models are estimated to investigate sources of variation in empirical estimates of the price elasticity of irrigation water demand. Elasticity estimates are drawn from 24 studies reported in the United States since 1963, including mathematical programming, field experiments, and econometric studies. The mean price elasticity is 0.48. Long-run elasticities, those that are most useful for policy purposes, are likely larger than the mean estimate. Empirical results suggest that estimates may be more elastic if they are derived from mathematical programming or econometric studies and calculated at a higher irrigation water price. Less elastic estimates are found to be derived from models based on field experiments and in the presence of high-valued crops.

Inelastic groundwater demand estimates were obtained for field crops throughout western regions. Results suggest that water pricing policies to achieve water conservation and water allocation efficiency affect income distributions as well as the intended objectives. Findings support earlier inelastic demand estimates from studies using experimental data, although demand for groundwater varies somewhat among climatic regions.

Crop-Water Production Functions in Economic Analysis

The nitrate contamination issue caused us to reexamine the relationship between nitrogen applied and profits. Test plot data we used to estimate nitrogen-yield production functions for economic analysis. Results showed (1) why fertilizer may be overapplied, (2) nitrogen may be reduced 20 30 percent with little effect on profits, and (3) the test-plot implicatons are conservative when applied at the farm.
