| Antibiotics have been used by pig producers for several decades, and are now used routinely. This study documents the current productivity and economic impacts of the use of antibiotics for growth promotion (AGP) by pig grower/finishers at the farm level. We evaluate the impacts of an AGP ban, and use of AGP by all pig grower/finishers for 61S90 days (a more production-efficient level), using data from the National Animal Health Monitoring System Swine 2000 Survey. Findings indicate that pig productivity improves with AGP. Relative to current use, an AGP ban would decrease producer profits by $1,400 per 1,020-head barn, and profits would increase by $1,992 for each grower/finisher barn when AGP is fed for 61 to 90 days. There is increasing concern about... |

| Questions of access to hospital services figure centrally in rural-health policy debates, yet few analyses exist that measure the importance of changes in hospital access in rural areas of the US. Of the studies that measure changes in access to hospital services over time in the literature, none use economic theory as the framework for the analysis. This paper proposes an economic approach based upon revealed preferences to measuring access to hospital services and quantifies the value of changes in hospital access over the period 1980 to 1999 for residents in rural counties in the US. Welfare measures are constructed for the years 1980 and 1999 for rural residents in all the rural counties of the US. On average the lowest levels of hospital access... |

| Nutrition labeling, in the words of the then FDA commissioner, David Kessler, was to “help millions of Americans make more informed, healthier choices.” Although the NLEA primarily focused on standardizing the nutrition facts label, its implementation also involved an informational and educational campaign on how to use the new nutrition facts label and the benefits of using it. Evidently label use more than doubled between 1989-91 and 1994-96. Most of the studies provide evidence of the effects of nutrition label use by comparing label users against non-users using data after NLEA was in effect. Using pseudo-panel data method, we find that implementing NLEA did not improve diet quality but use of labels did. Further, label usage showed no improvement in... |

| Antibiotics have been used in animal production for several decades. Antibiotics are used routinely now in pork production (NAHMS 2002). There is increasing concern about the use of antibiotics in animal production. There is no hard evidence supporting the link of antibiotic use in animals to observations of antibiotic resistance infections in people. Nonetheless a careful examination of the value of continued antibiotic use in agricultural, and in pork production in particular is warranted. Therefore, the objective of our study is to validate the productivity and economic impacts of antibiotic use for pig producers at the farm level. We use data from the NAHMS 2000 swine survey. We estimate the combined affects from antibiotics used for growth... |

| Participants in the Food Stamp Program consume more meats, added sugars, and total fats than they would in the absence of the program, while their consumption of fruits, vegetables, grains, and dairy products stays about the same. Participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) consume significantly less added sugars, which may reflect the substitution of WIC-supplied juices and cereals in place of higher sugar soft drinks and cereals. These findings come from a study of low-income Americans using the Continuing Survey of Food Intake by Individuals. |

| In this paper, we use quantile regressions on data from the 2005-06 wave of the Indian National Family Health Survey to study the determinants of child body-mass-index, height-for-age, and hemoglobin at different points of the conditional distribution. Our results show that only considering the conditional mean of the entire distribution can yield misleading results. In light of compelling evidence on sex-selective abortion and infanticide, we use a Heckman correction for our quantile regression to control for the “underreporting” of female births documented by Rose (1999). We find that household maternal health and education have larger effects at the lower end of the distribution than on the upper end, for all three child nutritional indicators. Results... |

| Public health experts are concerned about the diminishing efficacy of antibiotics. Some have called for a ban on growth-promoting antibiotics in animal agriculture. This study identifies the contribution of growth-promoting antibiotics in the grower/finisher phase of U.S. pork production. With National Animal Health Monitoring System swine data, relationships are estimated between growth-promoting antibiotic use and productivity. Results indicate improvements in average daily gain (0.5%), feed conversion ratio (1.1%), and mortality rate (reduced 0.22 percentage points); these productivity improvements translate into a profitability gain of $0.59 per pig marketed, or an improvement of 9% in net profits associated with growth promotion antibiotics. |

| Salmonellosis in people is a costly disease, much of it occurring because of food associated exposure. We develop a farm-to-fork model which estimates the pork associated Salmonella risk and human health costs. This analysis focuses on the components of the pork production chain up to the point of producing a chilled pork carcass. Sensitivity and scenario analysis show that changes that occur in Salmonella status during processing are substantially more important for human health risk and have a higher benefit/cost ratio for application of strategies that control Salmonella compared with on-farm strategies. |
