| Economic questionnaires were administered in 1997 and 1998 to farmers in the Indiana/Illinois, Kansas, and Iowa sites involved in the Areawide Pest Management (AWPM) program for the control of corn rootworms. These questionnaires provided information regarding variable and fixed costs of production for fields located within the management site and also the companion acreage. The economic analysis indicated that yields, variable costs per acre, and machinery costs per acre were not statistically different within a site across the inner core, outer ring, and companion acreage, with relatively few exceptions. This gives a solid baseline for a Net Present Value comparison between the soil insecticide and AWPM methods for control of corn rootworms, since... |

| While most Corn Belt farmers consider planting Bt corn to control European corn borer, southwestern Kansas farmers must also take into account an array of other insect pests, including corn rootworm, spider mites, and southwestern corn borer. This research uses a decision analysis framework to estimate the expected economic value of Bt corn in southwest Kansas. Mean per acre Bt values ranged from $12.49 to $34.60, well above the technology fee assumed to be $14 per unit, or $5.25 per acre at a seeding rate of 30,000 seeds per acre. The minimum value over all scenarios was $8.69 per acre. Using Monte Carlo simulation, it was shown that European and southwestern corn borer infestation probabilities, expected corn price, and expected pest-free yields are... |

| Child malnutrition is a problem that poses social and economic costs to individuals, households, communities, and nations, like Bolivia. Childhood malnutrition can be reduced through effective policy and health interventions such as those of the Consejo de Salud Rural Andino (CSRA) in Montero, Bolivia. The CSRA is a non-profit, private organization that operates three health care clinics in Montero, Bolivia. Low-income mothers and their children are provided with free or minimal-cost public health education and basic pre- and post natal medical services . Three separate clinic areas serve three different populations in terms of child nutritional status and demographic and socioeconomic characteristics. Effectiveness and priority intervention points... |
