| This report analyzes consumer demand and nutritional issues associated with nonalcoholic beverages purchased for at-home use by looking at demographic variables such as household size, household income, education level, and region. The beverages include milk, carbonated soft drinks, bottled water, fruit juices, fruit drinks, coffee, tea, and isotonics (sports drinks). The report's focus is on the impact of nutritional quality from beverage purchase choices that a household makes, looking at the household's availability of calories, calcium, vitamin C, and caffeine from these beverage choices. Using the Daily Values on the Nutrition Facts portion of the food label as a reference, we find that nonalcoholic beverages purchased for at-home consumption... |

| Cross-sectional data sets containing expenditure and quantity information are typically used to calculate quality-adjusted imputed prices. Do sample size and quality adjustment of price statistically alter estimates for own-price elasticities? This paper employs a data set pertaining to three food categories-pork, cheese, and food away from home-with four sample sizes for each food category. Twelve sample sizes were used for both adjusted and unadjusted prices to derive elasticities. No statistical differences were found between own-price elasticities among sample sizes. However, elasticities that were based on adjusted price imputations were significantly different from those that were based on unadjusted prices. |

| To date, mixed demand systems have been all but ignored in empirical work. A possible reason for the scarcity of such applications is that one needs to know a priori which prices and quantities are endogenous in the mixed demand system. By using a directed acyclical graph (DAG), causal relationships among price and quantity variables are identified giving rise to a causally identified demand system (CIDS). A statistical comparison is made of the traditional Rotterdam model with a Rotterdam mixed demand system identified through the use of a DAG. In this analysis, the respective Rotterdam demand systems consist of five products: steak, ground beef, roast beef, pork, and chicken. |

| The simulation of commodity prices has been undertaken using a myriad of techniques, with some omitting the cyclical component and others ignoring the presence of inter-temporal relationships expressed as autoregressive errors. This study examines the periodicity of cattle prices and the modeling of the cattle cycle for simulation purposes. The AIC criterion is used to determine lengths of various cycles to be included in a harmonic model, with a chained modeling approach providing the best representation of the cattle cycle. |

| A directed a cyclical graph (DAG) methodology was used to discover changes in price relationships among cull cow markets in the U.S. and Canada resulting from the trade ban initiated by the discovery of bovine spongiform encephalopathy (BSE, also called mad cow disease), in a Canadian cow in 2003. Comparison of the pre- and post-ban DAGs supports the hypothesis that large structural changes in the flow of cull cow market information has occurred with significant changes both within and between countries. The typical flow of information from south to north and east to west was disrupted. |
