AbstractThe short‐run supply of grain storage is reexamined. A classical, positively‐sloping function applies over most of the observed range. Because different grains compete for space, all grains were considered together. A novel method of computing price was used. This price of binspace is positively related to off‐farm grain stocks and sales of grain off farms—each deflated by bin capacity. Sales are a major influence, reflecting current handling demands as opposed to pure storage demands. Handling demands seem to act as a storage supply shifter. The position slope suggests existence of convenience yields for uncommitted bins.

摘要:

AbstractThe model we propose determines water balances for a project area and emphasizes interactions of a surface water‐groundwater system within the economic context of irrigation management. The program selects the tubewell, canal and surface drainage capacities, the project size, and the cropping pattern. Operation of the system is assumed to proceed subject to certain constraints on continuity at the river; capacity of the canals, tubewells, and drainage channels; mining of groundwater; crop water requirements; availability of land of different soil types; and permissible cropping patterns. A detailed irrigation planning example is presented.

摘要:

AbstractUrban pressures on farm real estate taxes have led, in the last decade, to adoption of differential assessment of farmland in at least 16 states. Broadly speaking, the laws fall into three categories: Preferential assessment, deferred taxation, and restrictive agreements. The laws are analyzed both from the standpoint of tax policy and from the standpoint of development policy. In neither case is it possible, given the present state of knowledge, to conclude firmly that the laws are desirable or undesirable. The analysis does, however, suggest a number of potential problems which should be analyzed before decisions are made.

摘要:

AbstractA multistage allocation model is designed to deal with two real‐world conditions that are bothersome in the application of spatial equilibrium models to the dairy industry. The multidimensional nature of milk allocation and the diversity of competitive structure within the industry must be faced to obtain realistic results. A set of recursive relations incorporating linear and quadratic programming formulations is used to handle the temporal and product‐use dimensions in addition to the spatial dimension. An application of the model to the New England dairy industry traces price, production, and consumption patterns over time.

摘要:

AbstractThis methodological study uses a simulation model to derive response surfaces in the Feed Grain Program. The model approximates an economic system at both micro and macro levels. It estimates response in terms of treasury costs, net farm income, income of participating farmers, and feed grain stock accumulation. Marginal rates of substitution among these response variables are estimated. For example, with a one‐cent reduction in loan rate, responses were $71.00 reduction in net income per farm; $134.00 reduction in income of participating farmers; decrease in stock accumulation of 33 million bushels; $48 million reduction in government costs.

摘要:

AbstractIf foodgrains producers are also the major consumers, price elasticity of production and price elasticity of marketed surplus should be distinguished. While the former is likely to be positive, the latter may theoretically assume either sign, and this introduces a complication in deriving the long‐run price elasticity of marketed surplus. Village‐level, cross‐sectional data are used to get a direct regression estimate of the short‐run price elasticity of marketed surplus for northwest India. The estimate seems to indicatenegativeelasticity. Other variables with statistically significant influence on marketed surplus are production level of foodgrains and income from milk.

摘要:

Abstract“Partial production functions” relating output to part of, rather than the entire array of, inputs employed are quite common in the production analysis of the biological subprocess in the farm‐firm. This article attempts to outline the framework within which this approach is reconcilable with the accepted theory of the firm. It also traces the derivation of the various cost functions from a set of partial production functions which, under certain conditions, may replace the single comprehensive one. An empirical example demonstrates the usefulness of this approach in relating cost variations to factor intensities or economics of scale which characterize a subprocess rather than the process of production as a whole.

摘要:

AbstractThe authors describe their recent experience in designing computer programs for use in farm management extension. They argue that the software (that is, computer programs) needs of extension are more demanding than the corresponding needs for research and that this explains the slow adoption of computer technology in the extension field. Although the development of appropriate computer programs can involve a major initial investment, this is nevertheless the only way to get the variable (and average) cost of computer advice to farmers down to an economic level.

摘要:

AbstractThis article examines a model for (1) coordinating activities in the development process and (2) inter‐temporally allocating resources required by the process. Network analysis (PERT) and recursive programming are integrated in the model, which is applied to data for a district in India. The findings provide insights into the sporadic nature of economic development and differential marginal value productivities of limiting resources over time. The integrated planning technique, resulting from the methodological study, appears to be especially useful for spotting potential bottlenecks sufficiently early to initiate action for eliminating them, thereby facilitating the development process.

摘要:

AbstractThe “demand deficiency” hypothesis, which has been used to explain the post‐1945 “export lag” of agricultural produce from non‐industrial areas, is irrelevant to the “export lag” of foodstuffs from overpopulated countries. South Korean experiences strongly suggest that a relatively high marginal propensity to consume food, combined with a relatively high price inelasticity of demand for food, makes the income redistribution consequent upon modernization a forceful factor in determining the export pattern of an underdeveloped country. Misleading export projections of foodstuffs during early stages of economic development result if income distribution effects are not taken into account.
