| Micronutrient malnutrition affects billions of people world-wide, causing serious health problems. Different micronutrient interventions are currently being used, but their overall coverage is relatively limited. Biofortification that is, breeding staple food crops for higher micronutrient contents has been proposed as a new agriculture-based approach. Yet, as biofortified crops are still under development, relatively little is known about their economic impacts and wider ramifications. In this article, the main factors that will influence their future success are discussed, and a methodology for economic impact assessment is presented, combining agricultural, nutrition, and health aspects. Ex ante studies from India and other developing countries... |

| Output quotas are known to be more efficient than input quotas in transferring surplus from consumers to producers. Input quotas, by distorting the shadow prices of inputs, lead to inefficient production and generate larger deadweight losses, for a given amount of surplus transferred. Yet, input quotas have been a ubiquitous tool in agricultural policy. Practicality considerations, as well as the difficulty to control outputs that heavily depend on stochastic weather conditions, are arguments that help understand why policy makers may favor input quotas over output quotas. In this paper, we offer an additional explanation that rests on efficiency considerations. Assuming that the regulator only has limited knowledge about the market fundamentals (supply... |

| This article examines the production risk effects and welfare implications of Bt corn adoption in the Philippines by specifically considering the impact of Bt on the mean, variance, and skewness of yields. Assessing the skewness effects of Bt provides further inferences about the downside risk protection of this technology in a developing country context. Stochastic production function estimation is utilized to achieve the study objective, including an approach that allows for examining the skewness effects of Bt within a damage abatement specification. Our results indicate that Bt corn do not have a statistically significant risk-reducing (i.e., variance-reducing) or downside risk-reducing (i.e., skewness-increasing) effect, the main benefit is through... |

| The purpose of this research report is to present an evaluation of advisory service pricing performance in 1995 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1995. The average net advisory price across all 25 corn programs is $3.04 per bushel. The range of net advisory prices for corn is quite large, with a minimum of $2.34 per bushel and a maximum of $3.81 per bushel. The average net advisory price across all 25 soybean programs is $6.61 per bushel. As with corn, the range of net advisory prices for soybeans is substantial, with a minimum of $5.75 per bushel and a maximum of $7.92 per bushel. |

| This work proposes a method to identify and evaluate the links between the economic and environmental management of a farm, its income, and sustainable GDP. The approach is designed to link micro and macro economic aspects and is based on certain indicators, chosen from among those obtained from analysis of the farm accounts, suitable for representing socially desirable objectives. Three different types of farm accounts are employed. An MADM method of quantitative MCDM analysis was used to make a joint evaluation of various objective indicators in different types of farm management. The work only presents the most interesting result of the research, which was the method itself and does not include the results of a specific case study which was made. This... |

| The information presented in this report represents data collected from farming and ranching operations in the southern two tiers of counties in Nebraska. This study was based on a random sample of 151 southern Nebraska farms that have annually-planted crop acreage. Information was obtained for the 1997 crop year. This data set is referred to as the MSU/UNL survey data. From the MSU/UNL survey data, the average size of the farming operations in the survey, in 1997, was 1,316 acres. Of these, 856 acres were planted to annual crops, and the remaining 460 acres included 61 acres in fallow, 29 acres in hay, 287 acres in range and pasture, 28 acres in CRP, and 55 acres in other uses. Operation size was largest in the west, due mostly to a large number of range... |

| Aquaculture, or more generally fish farming, and fisheries interact in several different ways. First, many types of fish farming require fish products as inputs, mostly for feeding purposes. Second, farmed fish and wild fish products compete in fish markets with consequences for both the industry and, of course, consumers. Third, fish farming generates various types of polluting agents that may affect wild fish stocks and their habitat. Several other interactions exist. This paper is primarily concerned with the implications of the first of these interactions, namely the input relationships, for the overall supply of fish products in the future. To the extent that the fish farming industry demands wild fish products such as fish meal, fish oil, etc.... |
