EFFICIENCY MEASURES USING THE RAY-HOMOTHETIC FUNCTION: A MULTIPERIOD ANALYSIS
Provedor de dados: 31
Autores: Neff,   David L.; Garcia,   Philip; Hornbaker,   Robert H.
Recent investigations have provided mixed assessments of farm firm efficiency. This analysis examined the efficiency of a homogeneous sample of central Illinois grain farms over a six-year period. A best-practice frontier was constructed using the ray-homothetic function, which allowed optimal farm output to vary with factor intensity. Efficiency measures were found to increase with temporal aggregation. The ray-homothetic approach was found to attribute high scale inefficiencies to larger sample farms in cases where the factor shares did not vary appreciably across farms. The findings suggest that policy recommendations regarding farm efficiency must be made with care.

Cost-Effectiveness of Alternative Environmental Policies for Reducing Non-Point Source Pollution in Public Water Supplies
Provedor de dados: 31
Autores: Mafoua,   Edouard; Hornbaker,   Robert H.
This study predicts farmers' response to policy alternatives aimed at alleviating non-point source pollution problems in a municipal water supply in Pike County, Illinois. The framework integrated simulation models with optimization models of the watershed to assess environmental policies. Results show how farmers are likely to alter agricultural management practices.

A DYNAMIC ANALYSIS OF WATER SAVINGS FROM ADVANCED IRRIGATION TECHNOLOGY
Provedor de dados: 31
Autores: Hornbaker,   Robert H.; Mapp,   Harry P., Jr.
A computerized grain sorghum plant growth model is combined with recursive programming to analyze the potential irrigation water savings from adopting irrigation scheduling and low pressure center pivot irrigation technology. Results indicate that irrigation pumping can be reduced with increased yields and net returns by adopting low energy precision application (LEPA) irrigation systems. Variations in input and output prices affect optimal irrigation quantities for low pressure irrigation systems less than for high pressure systems.
