摘要:

AbstractThis study develops a firm‐level bioeconomic simulation model capable of stochastically determining yields for the major dryland and irrigated crops in the central basin of the Ogallala Formation as a function of soil moisture and atmospheric stress during critical stages of plant development. The model is used to evaluate three methods of regulating groundwater irrigation—no restriction, a quantity limitation, and a graduated tax per unit above the quantity limitation. Results differ for poor and adequate water situations but indicate the potential value of an educational program on timing of irrigation application to maximize net farm income.

摘要:

AbstractThe purpose of the paper is to describe and demonstrate the usefulness of a dynamic regional economic model for evaluating resource development programs. The model results indicate that without development programs land may constrain livestock production after 1976. The growth in crop production is demand determined and will not exceed available land. A labor requirement of 15,400 man‐years is projected for 1976 with 2,600 unutilized. Output and income distribution effects of drainage, training, and land‐clearing development programs are assessed for the Interlake Area of Manitoba.

摘要:

AbstractThe nation's present interest in school finance reform concerns elimination of inequities in financing and improvement in the delivery of educational services. This paper examines one of the most popular school finance reform proposals that would allow the local school district to select an appropriate tax effort without directly linking quality of education to the district's wealth. Implementation of this reform proposal would result in a slight redistribution of income to poorer districts but would result in further inequities in quality of educational services.

摘要:

AbstractA technique for solving large‐scale mixed‐integer plant‐location problems is developed and utilized. The plant‐location problem is formulated as a minimum‐cost‐flow network problem and solved with a special purpose network code in conjunction with implicit enumeration. Implicit enumeration reduces the number of plant combinations that need to be examined. The technique was applied to resolve a cotton‐ginning subindustry's least‐cost organizational adjustment to exogenous factors and involved consideration of short‐run plant costs that were piecewise linear with fixed charges, two‐levels of variable labor cost, storage costs, and assembly costs.

摘要:

AbstractCombination of a single‐equation location model and interregional trade analysis into one model provides an effective tool to simultaneously determine regionally optimal numbers and sizes of processing plants and optimal interregional trading and pricing. The results of an earlier empirical application of the model on the prospective soybean industry in India are reviewed after four years of actual development. Private industry is allocating its processing plants in line with the pattern computed by the model, and a comparatively costly plan of arbitrarily establishing one government plant at an arbitrary location has not been implemented.

摘要:

AbstractThe dryeration process was originally advanced by agricultural engineers to improve grain quality by reducing stress cracks to the kernel normally incurred in the conventional drying process. This study demonstrates that the country grain elevator with dryeration facilities also uses substantially less energy to dry the same amount of grain and achieves higher profits above variable costs associated with drying operations than the elevator with conventional drying facilities, regardless of grain moisture conditions. These advantages are shown to be further magnified if energy prices continue to rise or if potential energy shortfalls are realized.

摘要:

AbstractMultiperiod linear programming and computer simulation techniques are integrated into a single recursive‐sequential model of the farm firm growth process. The model is tied to dynamic theories of the firm's planning behavior first developed by Hicks and more recently by Modigliani and Cohen. A central Kentucky beef farm empirically illustrates predictive features of the model. Three alternative beef production management strategies are compared to demonstrate the model's potential for explaining and predicting alternative farm firm growth processes.

摘要:

AbstractHistoric estimates of livestock production functions have used repeated observations on the animals to estimate the overall gain surface. The estimates involve autocorrelation accordingly. To circumvent this problem, gain isoquants are estimated directly by means of an instrumental variable approach. Data are from a swine experiment designed for the purpose with 648 hogs. Protein supplement and corn serve as the substitute inputs. Protein supplement is estimated as the instrumental variable. Isoquant equations then are predicted for three weight intervals. Finally, a decision model is applied for economic choice. Comparisons are made for various price sets of recent years.

摘要:

AbstractThe recent change in beef grades has stimulated discussion and opposition. Changes designed to improve the efficiency of the beef‐marketing system are being opposed by groups who adopt a micro perspective. The move to required yield grading continues to draw opposition. Analysis of original data from 118 beef carcasses and data from published studies indicates trimming procedures on fabricated cuts are important determinants of the change in cutability across yield grades. Research designed to investigate the implications of different trimming procedures is needed to clarify the applicability of yield grades.

摘要:

AbstractThree alternatives to the current peanut‐price support, acreage‐allotment program are considered. A linear programming framework is used to compare the effects of these policies on geographic location of peanut production, producer and consumer surplus, treasury costs, and value of allotments. Peanut production would expand in all areas except Texas under less restrictive production constraints. The largest expansion would be in Georgia and Alabama. Some version of the target price plan is considered to be a likely compromise program.
