| This study identifies barriers perceived by agricultural exporters and examines how these perceptions influence use of export market strategies. Ordered logit models are used to estimate effects of perceived barriers and firm characteristics on export market strategies. The results from these models show that perceptions about import restrictions influence use of diversification of exports across products, competition influences use of competitive export pricing, and overseas product regulations affect product adaptation for export markets. |

| One of the most important principles in any science is testing and consequently confirmation and falsification. In agricultural economics, the equilibrium displacement model is a popular modeling approach that presently is not testable and consequently cannot be confirmed or falsified. This paper presents four increasingly sophisticated procedures designed to overcome this limitation of equilibrium displacement models. An empirical illustration demonstrates the usefulness of these procedures in deciding between three alternative and theoretically viable equilibrium displacement models. |

| Consistent aggregation ensures that behavioural properties which apply to disaggregate relationships apply also to aggregate relationships. The agricultural economics literature which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to aggregation is reviewed. Tests for aggregation bias and errors of inference are conducted using indices previously tested for consistent aggregation. Failure to reject consistent aggregation in a partition did not entirely mitigate erroneous inference due to aggregation. However, inferential errors due to aggregation were small relative to errors due to incorrect functional form or failure to account for time series properties of data. |

| The increased prevalence of childhood obesity is a major concern for society. This study aims at exploring the influence of the parents (especially parental time allocation choices) on childrens obesity-related health outcomes and examining the potential differences between the fathers and the mothers marginal effects. A household with two parents and one child is modeled. The household production theory and the collective household modeling structure are combined. The model treats the mother, the father and the child as three separate agents with individual preferences. The two parents interaction is modeled within the collective model framework by assuming that they will reach Pareto efficient resource allocation between them. In order to capture... |

| This paper presents an information based model averaging and internal meta-analysis procedure that is easily applied to a large model space. In the application, the procedure is used to investigate the efficacy of some recently contested commodity promotion programs. The investigated model space consists of 576 demand systems. The internal meta-analysis indicates that theoretical restrictions and evaluation points are more important than alternative functional forms and explanatory variables in determining the elasticity values. The model averaging weights strongly support the theoretically consistent classical demand systems without promotion. The weighted or meta-price and meta-expenditure elasticities are presented and discussed. |

| Domestic tobacco producers have faced increasing competition from imported tobacco since the late 1970s. Much of the debate has centered on the unknown quality of imported tobacco. This study provides a discussion and clarification of the concept of quality, and demonstrates a method of measuring the average quality of imported tobacco. The results show that since 1977, imported tobacco has been steadily decreasing in average quality and moving toward lower quality producing countries and types of tobacco. The reasons for this decline are discussed along with the policy implications. |

| In operation for more than 40 years and now in all 50 states and 6 territories, the Expanded Food and Nutrition Education Program has become a cornerstone in US nutrition education. The aim of the program is to assist limited resource audiences to acquire the knowledge, skills, attitudes, and changed behavior necessary for nutritionally sound diets, and to contribute to their personal development and improvement of the overall family diet and nutritional well-being. However, very little is known about the effectiveness of this program, especially at the national level. The purpose of this research is to determine the effectiveness of money spent on the Expanded Food and Nutrition Education Program in satisfying its stated goals for adult participants.... |

| The USDA's Market Access Program (formerly Market Promotion Program) recently underwent a major change to redirect all branded products export promotion funds to small domestic firms and cooperatives. The redirection responded to criticisms by the General Accounting Office of past allocations of branded products export promotion funds to large, experienced exporters. This study uses a firm-level analysis to examine whether firm size and export experience matter in how effectively firms use the promotion funds to increase their revenues. The results support neither the GAO criticisms nor the recent program redirection. |

| Many agricultural economics departments are concerned about the vitality of their Ph.D. programs. A particular problem is insufficient student numbers to justify teaching certain courses or fields. As a consequence, much faculty time can be spent debating alternative program structures without any real idea of the likelihood that a proposed program structure will succeed. This article presents a framework for deriving some analytical and empirical results for alternative Ph.D. program structures. A downloadable program is used to generate some representative results that will hopefully help others minimize speculations and time spent in committee or departmental meetings. |
