    The demand for gasoline and diesel fuel in agricultural use in Virginia
    Capps, Oral (Virginia Polytechnic Institute and State University, 1977)
    The objectives of this study were: (1) to determine the usage patterns of gasoline, diesel fuel, and other fossil fuels in different types of agriculture; (2) to determine the demand relationships for gasoline and diesel fuel in agricultural use and to identify and assess the major factors that affect these relationships; and (3) to determine differences in the demand relations for gasoline and diesel fuel in agricultural use. The usage patterns of gasoline, diesel fuel, and other fossil fuels in agricultural production in Virginia, the South, and the U.S. were developed from cross-sectional data provided jointly by the Economic Research Service and the Federal Energy Administration. From the static theoretical development and the dynamic and technological adjustment concepts of derived input demand, the theoretical demand relationships for gasoline and diesel fuel were formulated. Asymptotically efficient, asymptotically normal, asymptotically unbiased, and consistent parameter estimates were obtained by employing a generalized least squares (GLS) procedure on the Parks model in combining cross-sectional and time-series data. All data were from the period 1971 through 1976. The agricultural sector in Virginia appears to adjust to changes in economic factors and other variables influencing the demand for gasoline and diesel fuel. While farmers.appear to be somewhat passive to increases in the real prices of gasoline and diesel fuel in the current period, they are quite responsive to such increases when given time to adjust their usage patterns.

    Nonconvenience and convenience food use by younger and older elderly Americans
    Pearson, Joanne M.; Walters, Kathleen Roe; Axelson, Julein; Capps, Oral (Virginia Agricultural Experiment Station, 1986-05)
    The focus of this study is on analyses of the use of nonconvenience and various types of convenience foods by households with a male or female head 65-74 years of age (younger elderly) and those with a male or female head 75 and older (older elderly) in the United States. These households are considered elderly households although in some cases they may include some nonelderly individuals. Convenience foods are defined in the study as foods that are partially or fully prepared when purchased. The data source for this study is the 1977-1978 Nationwide Food Consumption Survey conducted by the United States Department of Agriculture. Both groups of elderly households spend approximately 59 percent of the at-home food dollar on nonconvenience foods, and 19, 16, and 6 percent on basic, complex, and manufactured convenience products, respectively. Nutrient content of the foods used is often significantly higher in younger than older elderly households, as is total expenditure for food per household member. However, nutrients obtained per dollar expended are frequently higher in older elderly households than in younger elderly households. The share of the food dollar spent on the various nonconvenience and convenience food classes by elderly households is related to several sociodemographic characteristics of the population. Geographic region, season, household size and income, and race of the respondent, as well ivas education and sex of the meal planner affect the budget share allocated to nonconvenience foods. Geographic region, urbanization (population density), and sex of the respondent are related to the budget share apportioned to basic and complex convenience foods, while the budget share allocated to manufactured convenience foods is influenced by sex of the meal planner, shopping frequency, and household income.
