| When using household-level data in examining consumer's demand it is common to find that consumers purchase only a subset of the available goods, setting the demand for the remaining goods to zero. Ignoring such censoring of the dependent variables in the estimation can lead to biased parameter estimates. In this paper we investigate the household's demand for six types of whole grain and non-whole grain breakfast cereals and products using a censored Almost Ideal Demand System (AIDS) and estimate the parameters of the demand system via Bayesian methods. Using 2006 ACNielsen Homescan data we find that demand for whole grain and non-whole grain ready-to-eat cereals is less responsive to changes in prices; demand for whole-grain bars and non-whole grain hot... |

| WIC, the Special Supplemental Nutrition Program for Women, Infants, and Children, is a widely studied public food assistance program that aims to provide foods, nutrition education and other services to at-risk, low-income children and pregnant, breastfeeding and postpartum women. From a policy perspective, it is of interest to assess the efficacy of the WIC program - how much, if at all, does the program improve the nutritional outcomes of WIC families? In this paper we address two important issues related to the WIC program that have not been extensively addressed in the past. First, although the WIC program is primarily devised with the intent of improving the nutrition of "target" children and mothers, it is possible that WIC may also change the... |

| An important dimension of product differentiation and segregation for specialty crops is the added handling and transaction costs incurred. Some forms of business organization may realize lower costs of providing such services, and if specialty crop production is growing relative to commodity production, these two factors may have implications for industry structure. We use data from an Iowa grain handling survey to test hypotheses developed in the non-empirical transaction-costs literature with respect to organizational and financial governance of cooperatives and private and corporate firms. Preliminary results are discussed with respect to business organizations, added costs, investments, crops, and contracting. |
