| In this project, a predictive time model was developed for an Anglia Autoflow mechanical chicken catching system. At the completion of poultry growout, hand labor is currently used to collect the birds from the house, although some integrators are beginning to incorporate mechanical catching equipment. Several regression models were investigated with the objective of predicting the time taken to catch the chicken. A regression model relating distance to total time (sum of packing time, catching time, movement to catching and movement to packing) provided the best performance. The model was based on data collected from poultry farms on the Delmarva Peninsula during a six-month period. Statistical Analysis System (SAS) and NeuroShell Easy Predictor were used... |

| The U.S. broiler industry is highly vertically integrated and increasingly concentrated in the number of firms and production areas. These structural elements could have implications for performance and the functioning of the law of one price (LOP) across regions. This article investigates this using data on four regional markets. Cointegration results indicate that regional prices are spatially linked in the long run, but pairwise cointegration was not found, suggesting that the LOP does not hold. Causality tests confirm the relative importance of price shocks from the South. This finding is reflective of price coordination by firms with production in multiple regions. |

| A consumer survey and Tobit analysis were used to determine the effect of message framing and other factors on self-reported organic food purchase likelihood. Negative framing, which emphasizes the possible negative consequences of conventional agricultural techniques, led to a "boomerang effect" that resulted in lowered purchase likelihood of organic food by consumers with high trust in food safety. Consumers with significantly higher purchase likelihood had high perceived risk from pesticides and high prior knowledge about organic methods. African Americans and those with less than a high school education had lower purchase likelihood. |

| This study examined consumer willingness to pay for first- and second-generation genetically modified (GM) and organic foods and for non-GM foods, dependent on tolerance for GM content. Data from a survey of students were examined using a heteroskedastic two-limit Tobit model. Results showed consumers were willing to pay significantly more for organic and second-generation foods over first-generation GM foods, which suggests a niche market for second-generation GM foods may be possible. For non-GM foods, consumers were indifferent between a 100- and 99-percent threshold, but did not view 95-percent non-GM foods as more valuable than foods with unknown GM. |
