ACCOUNTING FOR SPATIAL CHARACTERISTICS OF WATERSHEDS IN EVALUATING WATER POLLUTION ABATEMENT POLICIES AgEcon
Qiu, Zeyuan; Prato, Anthony A..
This study evaluates three agricultural nonpoint pollution abatement policies: regulating the spatial pattern of agricultural activities, ambient tax, and abatement tax/subsidy. All three policies incorporate spatial characteristics of agricultural emission loading and movement for an agricultural watershed in the Midwest. The effects of spatial variation in natural conditions and landscape features on agricultural emissions and crop yield are evaluated using a newly developed biophysical simulation model and experimental data. While the policies are equally cost effective in reducing agricultural nonpoint source pollution, their implementation feasibility is quite different.

Cost Efficiency and Scope Economies of Crop and Livestock Farms in Missouri AgEcon
Wu, Shunxiang; Prato, Anthony A..
This study investigates productive efficiency for a sample of Missouri crop-only (specialized) and integrated crop-livestock (diversified) farms using a cost frontier approach. Results suggest that significant cost inefficiency exists among sample farms. Lower cost efficiency in both types of farms was attributed to improper scale of operations and mis-allocation of inputs. On average, diversified farms were as technically and scale efficient as specialized farms. Lower allocative efficiency diluted gains in technical efficiency and resulted in greater cost inefficiency for diversified farms than for specialized farms. Technical efficiency was independent of farm size, whereas allocative, scale, and scope efficiencies were not.

MULTIPLE-OBJECTIVE DECISION MAKING FOR AGROECOSYSTEM MANAGEMENT AgEcon
Prato, Anthony A.; Fulcher, Christopher L.; Wu, Shunxiang; Ma, Jian.
Multiple-objective decision making (MODEM) provides an effective framework for integrated resource assessment of agroecosystems. Two elements of integrated assessment are discussed and illustrated: (1) adding noneconomic objectives as constraints in an optimization problem; and (2) evaluating tradeoffs among competing objectives using the efficiency frontier for objectives. These elements are illustrated for a crop farm and watershed in northern Missouri. An interactive, spatial decision support system (ISDSS) makes the MODEM framework accessible to unsophisticated users. A conceptual ISDSS is presented that assesses the socioeconomic, environmental, and ecological consequences of alternative management plans for reducing soil erosion and nonpoint...

SETTING PRODUCTION GOALS FOR FEDERAL COAL LEASING AgEcon
Prato, Anthony A..
National and regional production goals have been established by the Department of Energy as guidance to the Department of the Interior in determining the location and rate of federal coal leasing as well as the determination of leasing targets for individual coal lease sales. This paper discusses the analytical procedures used by the Department of Energy in setting the 1980 biennial coal production goals. The goals are presented and compared to production forecasts obtained from other sources. Implications of these goals for federal coal leasing policies are considered.

WATERSHED-SCALE ECONOMIC AND ENVIRONMENTAL TRADEOFFS INCORPORATING RISKS: A TARGET MOTAD APPROACH AgEcon
Qiu, Zeyuan; Prato, Anthony A.; Kaylen, Michael S..
This paper evaluates the economic and environmental tradeoffs at watershed scale by incorporating both economic and environmental risks in agricultural production. The Target MOTAD model is modified by imposing a probability-constrained objective function to capture the yield uncertainty caused by random allocation of farming systems to soil types and by introducing environmental targets to incorporate environmental risk due to random storm events. This framework is used to determine the tradeoffs frontier between watershed net return and sediment yield and nitrogen concentration in runoff in Goodwater Creek watershed, Missouri. The frontier is significantly affected by environmental risk preference.
