| 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... |

| One of the greatest challenges facing agriculture for the foreseeable future is to resolve conflicts caused by a growing competition for the services of the soil, water, and other natural resources on which agriculture depends-driven by growing demands for food, fiber, and for nonagricultural services these resources provide. To meet this challenge, research is needed which is integrated across the relevant sciences to better understand and predict the properties of agricultural production systems in all of the dimensions that have come to be represented by the concept of sustainability. If we were to achieve this capability to analyze agriculture as a managed ecosystem, it would be possible to move beyond the current regime of agricultural policies,... |

| A method of decomposing the growth in total factor productivity into effects due to nonconstant returns to scale and technical change was applied to the U.S. agricultural sector. The scale effects and technical changes were measured using an economically estimated two-output, three-input translog cost model. Total factor productivity as conventionally measured grew at an average annual rate of 1.56% from 1950-82. This growth rate, however, misrepresented the rate of technical change in U.S. agriculture primarily due to the nonconstant scales effects. |

| This study examined possible economic impacts on Northern Plains grain producers of policies that could be undertaken by the United States to comply with the Kyoto Protocol. The paper begins with a discussion of the potential effects of the Kyoto Protocol on prices of energy and inputs used in agricultural production. The next section describes the data and econometric models that were used to develop a field-scale, stochastic simulation model of the crop production system typical of the Northern Plains. This model is based on econometric production models estimated with a spatially referenced, statistically representative sample of farmers in Montana. The simulation analysis shows that the impacts of higher energy prices would tend to discourage the use... |

| This study develops an integrated assessment approach for analysis of the economic potential for carbon sequestration in agricultural soils. By linking a site-specific economic simulation model of agricultural production to a crop ecosystem model, the approach shows the economic efficiency of soil carbon (C) sequestration depends on site-specific opportunity costs of changing production practices and rates of soil C sequestration. An application is made to the dryland grain production systems of the U.S. Northern Plains which illustrates the sensitivity of the sequestration costs to policy design. The marginal cost of soil C ranges from $12 to $500 per metric ton depending upon the type of contract or payment mechanism used, the amount of carbon... |

| Many firms anticipate that a cap on greenhouse gas emissions will eventually be imposed, either through an international agreement like the Kyoto protocol or through domestic policy, and have started to take voluntary actions to reduce their emissions. If agricultural producers participate in the emerging market for tradable C-credits, it must be possible to verify that actions farmers take do increase the amount of C in soils and this increase can be maintained over the length of the contract. In this paper we develop a prototype measurement and monitoring scheme for C-credits sequestered in agricultural soils and estimate its costs for the small grain-producing region of Montana using an econometric-process simulation model. Three key results emerge... |

| In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous. The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for linking econometric production analysis to the time-specific analyses in other scientific disciplines used to assess the environmental or human health impacts of agricultural production practices. The case study of fungicide use on Ecuadorian potatoes was conducted with a unique data set containing detailed information on both quantity and timing of input use. The results showed that both quantity and timing of chemical use were responsive to economic variables. |
