The role of primary exports in the economic development of a country or region has been subject to much debate. The “staple theory” has been proposed as an explanation of the beneficial effect of primary exports on the economic development of Canada and the United States. However, one authority argues that the staple theory is applicable only to the special case of a new underpopulated country. This paper shows that primary exports have stimulated development in the state of Sonora, Mexico. Data showing the increase in primary production and exports between 1950 and 1960 are linked to the increase in manufacturing employment in industries producing inputs for primary production, industries processing primary products, and industries producing products to satisfy increases in final demand. The role of government policies, institutional arrangements, and the nature of the production functions for primary products are examined in an effort to determine the impact of primary exports on manufacturing activity. This study illustrates that the staple theory provides insight into the development or lack of development of all countries exporting primary products. L'IMPORTANCE DES EXPLOITATIONS DE BASE DANS LE DEVELOPPEMENT ECONOMQUE: ?APPLICATION DE LA “THEORIE DES DENREES PRINCIPALES” DANS ?ETAT DE SONORA AU MEXIQUE - Le rôle des exportations de base dans le développement économique ?un pays ou ?une région a fait le sujet de bien des débats, La “théorie des denrées principales” a été proposée comme une explication de ?effet avantageux des exportations de base sur le développement économique du Canada et des États-Unis.

Due to the time lag between investment and payoff, the price-taking nature of agriculture, stochastic weather variables and other factors, the uncertainty faced by decision makers in agriculture is greater than and different from that confronting managers of most other sectors of economy. In this paper, game theory models have been applied to the problem of decision making under uncertainty in agriculture. The authors examine and compare the pros and cons of the four conventional theories of choice in decision making in agriculture. The four theories are: (a) Wald's maximin criterion, (b) Laplace's principle of “insufficient reason”, (c) Hurwicz's “optimism-pessimism” criterion and (d) Savage's “regret” criterion. In this study, applications have been made to the choice of type of farming, optimum dosage of fertiliser and manure and the most appropriate time of selling agricultural produce. The authors propose an additional theory of choice—the criterion of “benefit”—which seems more appropriate than the conventional theories under many situations. 相似文献

The low position of agricultural workers in the wages scale is examined in the context of National Plan objectives to increase opportunities for the labour force. The results of a survey of lubour use on 55 Yorkshire farms over the past five years are presented. The regular hired labour force on these farms has been cut by a quarter, and some farms still report surplus labour. Data on the farm workers employed and those which have left the farms is given. The characteristics of the ‘ideal farm worker’ as seen by the farmers are investigated and conclusions regarding the likely success of a wages structure in agriculture are drawn. The implications of a rise in the minimum agricultural wage to £14 a week are discussed in the light of the survey results. 相似文献

The purpose of this paper is to review the demand structures implied by several common utility specifications. After a review of the Hicks-Allen measures of the demand structure, four utility functions are examined including the Cobb-Douglas, CES, and Mukerji functions. The results indicate that the most popular utility specifications provide patterns of demand parameters which do not conform to those made in estimation of commodity demand functions L'objet de cet papier est passer en revue des structures commandes de quelques caractéristique de ?utilité.

A simple utility-based model of risky wool production is presented. Evaluation of the model indicates the effect on optimal stocking rate of changes in the degree of risk aversion, farm area, variable cost, fixed cost, wool cut, wool price, variance of wool price, climatic variability and tax rate. It is shown that the utility hypothesis implies a lower optimal stocking rate than does expected profit maximization and hence implies a discrepancy between private and public optimal resource use which it is suggested, might be mitigated by a progressive bounty on wool production. 相似文献

A decision theoretic approach to agricultural policy decision making is examined to discover whether a utility function of an Australian Wool Corporation decision maker can be established and, if so, whether this can be used to improve the policy analysing performance of an agricultural sector linear programming model. After discussing the theoretical requirements of the utility function elicitation and the elicitation procedures, the characteristics of the resulting functions are examined. A means for its inclusion in a linear programming framework is described and some analysis of policy is carried out. The general conclusions are that the relevance of the agricultural sector analysis is enhanced by the use of such a utility function. 相似文献

For the ten crop seasons 1979-80 to 1988-89, returns to producers in the Australian wheat industry were underwritten by a government-guaranteed price floor. Similar schemes operate in other rural industries (dairy, apples and pears, dried fruits). Although the underwriting provisions have only been triggered once (in the 1986-87 season), the provision of this scheme has acted to reduce the risk normally associated with returns to producers of wheat in all years of its operation. This reduction in risk has been granted free-of-charge by the Commonwealth Government. The guaranteed price can be viewed as a put option taken out by the Government on behalf of growers — it gives growers the option to sell to the Australian Wheat Board at this floor price. The aim of this paper is to apply to this underwriting arrangement the Black-Scholes formula for valuing options, in order to estimate the cost that growers would otherwise have had to pay to obtain cover (through put options) equivalent to the guaranteed price. We also estimate the magnitude of this form of assistance to the industry, which (until now) has not been taken into account unless the returns to growers fell below the guaranteed price. 相似文献

This paper is concerned with five main topics-the size of the agricultural tasks ahead of us during a period of increasing change in the poorer countries: recent trends in food supplies and agricultural output; the constraints, including those outside the domain of agronomy, which hinder growth in output; the technical prospects in agronomy as they can be perceived at present; and some thoughts about the nature of future change in rural areas. 相似文献

In our complex industrialised society there can no longer be a clear cut distinction between education and the training for a profession. Pressure from society for highly specialised knowledge and from students for satisfaction of vocational needs has resulted in the greater development of applied subjects. The aim of teaching in Agricultural Economics is to present a variety of subject matter within the framework of cohesive degree structures consistent with an academic discipline, while as far as possible fitting a student for a professional career in the field of Agricultural Economics. In the ever widening range of professional activity a distinction which has relevance to teaching can be made between the practising agricultural economist and the academic agricultural economist. For the former some professional training has to be incorporated in the first degree scheme. The need in industry and government is for economists who are prepared to make direct economic appraisals and the practising economist will therefore be involved in problem solving in a sphere where non-economic consideration have also to be weighed. He can best be fitted for his environment if he is aware of the interaction between economics and other relevant disciplines. 相似文献

The introduction of new technology into agriculture is a central feature of development schemes, but is regularly criticised because of its distributive effects. Technology change is unavoidably biased, however, and cannot easily be used to serve specific distribution objectives. Ex post studies do not necessarily guide the appropriate choice of technology as they rarely offer causal explanations. Predicting the consequences of innovation is hampered by the narrowness of established economic models and the conceptual indefiniteness of technology as a variable in those models. In the absence of a wider system framework, technology for development is selected according to more general guides. These emphasise either the primacy of output objectives or advocate technology forms presumed appropriate to distribution objectives. Neither adequately substitutes for a broad framework to guide the choice of technology as an instrument in development. 相似文献

Public utilities which apply roughly uniform prices to all consumers often engage in cross-subsidisation — charging prices which are below cost for consumers in low population density areas but above cost for consumers in high density areas. The distributional and allocative implications of this practice are examined and it is concluded that some cross-subsidisation may be justifiable on welfare grounds even where no externalities exist. There is, however, little empirical evidence released by utilities to enable assessment of the efficiency of their practices. If nothing else, we highlight the need for greater public disclosure of pricing practices by public utilities. 相似文献
