| Study uses a 16-question negotiation ethics survey to examine ethical attitudes among undergraduates at Oregon State, Auburn, Michigan State and Texas A&M Universities. About 600 students were surveyed. The results revealed that gender, age, religious activity and community service were major factors influencing ethical behavior. Family income, size of hometown, and most high school activities had virtually no influence on ethical behavior. |

| Dynamic programming techniques were used to evaluate the effects of alternative levels of normal flex acreage requirements on a Midwestern corn-soybean farm and a Southeastern cotton farm. Results indicate that increasing normal flex acres from the current level of 15 percent to 35 percent would provide inducement for farmers in both regions to plant more soybeans. In general, the cotton farm incurs considerably higher expected losses from the change. Thus, there are unequal regional consequences of such a policy change. |

| The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. Farmers will adopt and continue to utilize cover crops in their production systems as long as the perceived benefit of using cover crops (e.g. increased yield, higher profits, and improved soil productivity) is positive. The perceived benefits, while partially based on actual changes, may be influenced by demographic, economic and management factors. The purpose of this paper is to examine the demographic and management factors affecting the perceived benefit, in terms of improved crop yield, of using winter annual cover crops. A tobit model is estimated using survey data of Alabama farmers examining cover crop use and management. The model examines the... |

| Using data from the 1999-2002 rounds of the continuous National Health and Nutrition Examination Survey (NHANES), the inter-relationships between food insecurity, diet quality and body mass index (BMI) were examined. The impact of smoking and alcohol consumption behaviors were also examined. The relationship between BMI and food insecurity was found to be sensitive to the specification of control variables, such as age, income, and race and ethnicity. Smoking was directly associated with lower BMI for both men and women; while alcohol consumption was directly associated with lower BMI only for men. Smoking negatively affected food insecurity and diet quality, as measured by the Healthy Eating Index (HEI). For women, these indirect effects were... |

| An econometric model of cotton acreage response was estimated for four distinct production regions in the United States. This work builds on previous work in the area of supply response under government farm programs and provides up-to-date regionalized estimates of own-price elasticity of cotton acreage supply. The own-price variable used in this study is a weighted combination of expected market price and government policy variables. Results indicate regional similarity in response to own price but differences with respect to the prices of alternative enterprises. Differences in regional response to paid diversion are also indicated. |

| Linear programming and enterprise budgeting were used to analyze rotation options, including an energy crop (intercropped grain sorghum and velvet bean), for a representative south Alabama farm. The energy crop was priced beginning at $30.00 per ton, at which price it did not enter the solution. At prices of $41 per ton or higher, the energy crop was produced. |
