The aim of the paper is to investigate certain aspects of the post‐adoption behaviour of dryland cotton farmers in the Ubombo and Hlabisa magisterial districts of KwaZulu. Particular attention is paid to the socio‐economic determinants of the success (returns per hectare) of the household cotton enterprise.

Multi‐stage sampling methods were used to draw a random sample of fifty cotton‐farming households from each of the two study districts. The data were collected by interview survey and analysed using principal components and regression techniques.

Results suggest that the success of the household enterprise in both areas is largely determined by the socio‐economic environment under which the producer operates. The most important success‐determining factors are those relating to the human capital endowments and economic status of the household.  相似文献

This study discusses how perceptions of ethics are formed by certified public accountants (CPAs). Theologians are used as a point of comparison. When considering CPA ethical dilemmas, both subject groups in this research project viewed confidentiality and independence as more important than recipient of responsibility and seriousness of breach. Neither group, however, was insensitive to any of the factors presented for its consideration. CPA reactions to ethical dilemmas were governed primarily by provisions of the CPA ethics code; conformity to that code may well be evidence of higher stage moral reasoning.Gregory A.

We propose to introduce some economic performance variables of the firms and relate these with the corresponding frontier efficiency measures of 13 industries of the Belgian manufacturing sector in 1978. In order to find groups of similar firms by applying a cluster technique, we assume that this relationship is of a product life cycle nature.In the light of the product life cycle scheme itself and variations of it we can consider the possible explanatory variables of technical inefficiency in each group of firms as sources which intensify or slow-down the economic performance of the firm under consideration. Some cautious characterization of the top and bottom level clusters is formulated and linked to the efficiency issue.This paper was processed by N. R. Adam  相似文献

Beginning in 1992, the use of resource based relative value scale (RBRVS) will greatly change the way physicians are reimbursed for services to Medicare patients. This new system will also have implications for trust funds and corporate providers of health care benefits.  相似文献

Earlier experimental evidence indicates that some decision makers under-invest in information when it is costly. This insight is applied to the cost–benefit analysis of the provision of data obtained by satellites. In fields like agriculture, remotely sensed information of great precision can be provided to additional farmers at minimal extra costs if a service for farmers with similar information needs is set up. Here, the tendency to under-invest in information asks for creative solutions by the private sector: bankers may work together with rational producers in setting up the information service and promoting it. However, if producers financial resources are insufficient, public intervention, in the form of a free information service may be necessary.The author would like to thank an anonymous referee, Stephan von Cramon-Taubadel, Sean Flynn, Daniel Heller, and Carlos Lenz and participants of the Lisbon Conference of the International Atlantic Economic Society, particularly Asatoshi Maeshiro, for helpful comments.  相似文献

The notion of a mixed-strategy Nash equilibrium suffers from three inherent difficulties. First, given the equilibrium strategies of other players, there are many best replies. Second, the equilibrium is unstable. Third, comparative statics results are counterintuitive. We demonstrate that these difficulties all have their origin in von Neumann and Morgenstern′s expected utility. In contrast, players with "quadratic utility" have unique best replies and the Nash equilibrium appears to yield intuitive comparative statics results.

The competitive environment in long-distance telecommunications markets changed considerably with the divestiture of AT&T in 1982. A variety of providers appeared, offering myriad services. In this environment, customer selection of preferred long-distance carrier became more complicated and more important.In this paper, we analyze and quantify the determinants of this choice. To our knowledge, this focus is distinct. By contrast, the literature to date has analyzed the behavioral determinants of calling volume (local and long-distance) and the selection of local service options.In our analysis, we allow the alternative carriers to differ in terms of tariffs, reputation, quality, access, and specialized customer services. We quantify the interactive effects of these carrier attributes and customer demographics upon the selection of carrier. Price and income elasticities are estimated. A distinguishing feature of our analysis is that it examines behavioral differences among households in equal-access and unequal-access areas. We find that households assured of the convenience of 1 + dialling for their chosen carrier in equal-access areas display more rational and sophisticated decision making. On the other hand, households in unequal-access areas display greater status quo effects in their decision making.  相似文献

In this paper we analyze the impact on firm profits of the environmental regulations in the Swedish pulp and paper industry. The approach taken is a non-parametric programming model of the technology. A feature of this industry is that environmental regulations are determined individually for each mill. A question, then, is if these individual regulations have a similar impact on firm profits. The approach in this paper allows us to calculate both the regulated and unregulated profits, which means that the severity of the regulations, in terms of foregone profits, can be calculated for each mill. The empirical result shows that the impact on the mills varies substantially, and that the burden from the regulations is less severe in 1990 than in 1989.  相似文献
