In recent years, the Federal government has placed more emphasis on working-land conservation programs. Farmers can be reimbursed for adopting certain conservation practices, such as the installation of in-field or perimeter conservation structures, to enhance water quality and soil productivity. In an effort to better understand the relationships between operator motivations, program incentives, and the environmental benefits of conservation programs, a multi-agency survey, the Conservation Effects Assessment Project-Agricultural Resources Management Survey (CEAP-ARMS), was conducted in 2004 across 16 states representing more than one-million farmers growing wheat. The nationally representative survey integrates Natural Resources Inventory (NRI) data on... |

USDA uses the concept of "publish-ability" rather than statistical reliability of an estimate for quality validation of USDA estimates, which is solely based on the sample size and the coefficient of variation (CV). We demonstrate conceptually how the reliability of the sample mean can be tested by estimating the upper and lower bounds of the confidence interval for an unknown population mean using the CV. However, the reliability test for the sample mean can be made only under the normality assumption. USDA multiple-way Agricultural Resource Management Survey (ARMS) estimates are used to illustrate the relative measure of precision for sample-based estimators. |

Soybean production ranks among the largest agricultural cash crops in the U.S., second only to corn. U.S. soybean production topped 3 billion bushels in 2005 with sales of $17 billion. Approximately 58% of U.S. soybeans are grown in Iowa, Illinois, Minnesota, Indiana, and Nebraska. A small percentage of the U.S. soybean crop, 2%, goes to human consumption in the form of whole beans, soybean oil, and soybean meal products. A third of the crop, 1 billion bushels per year is exported annually to China, EU, Mexico, Japan, and Taiwan, and other countries. Most of the crop, 2 billion bushels, goes to the U.S. livestock industry to feed poultry, hogs, and cattle. Variations in the supply of soybeans thus directly impact livestock production. In recent years,... |

This study used the 2005 ERS CEAP-ARMS data for corn production to first compare key operator, field, farm, economic, and environmental characteristics of conservation program participants with non-participants, by farm-size class. We then estimate a cost-function based technology adoption model of producer decisions regarding the allocation of field-level acres between corn production and infield and perimeter-field conservation structures to examine how these conservation choices differ between program participants and non-participants, while accounting for differences in other field, farm, and environmental factors. Our null hypothesis is that the average conservation structural practice acres across U.S. corn acres supplied by growers participating... |

Soybeans, the second highest cash crop following corn in the U.S., have come under attack by invasive species, the soybean aphid from the North and soybean rust from the South. We estimated the economic losses resulting from soybean aphid infestation by using a dynamic equilibrium model. Results indicate that, first, the reduction of soybean production resulting from soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to the domestic demand. Second, the economic losses to U.S. soybean producers would grow on average annually between $12.8 million and $23.4 million during the first five years of infestation. In the longer-run, soybean producers would suffer greater... |

Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnitudes of the impacts of tax credits and blending mandates on fuel-energy market equilibrium prices. Our results indicate that first, the prices of all fuels including conventional gasoline, ethanol, and blended gasoline decline as the biofuel tax credit increases, but they increase as the rate of the blending mandate increases. Second, the shadow value of a blending... |
