"The objective of this paper is to present a model of constrained utility-maximizing behaviour which is able to explain several features of marriage. The model predicts that individuals meet in the marriage market and trade characteristics, in which they are relatively well endowed, to obtain characteristics in which they are less well endowed. The model implies a positive age differential in favour of the husband due to biological differences. This differential is shown to be attentuated by differences in earnings capacity and human capital investments. The model also has implications for dynamic aspects of marriage and provides an explanation for the secular increase in females' age of first marriage and difficulty experienced by females in the post thirty-year age group in finding suitable partners. An examination of unit record data on residents of metropolitan California from the 1980 United States Census reveals systematic patterns in the data are consistent with the theory."  相似文献

A basic needs survey was conducted among people living on two agricultural smallholder schemes in Venda. The paper describes the research methodology and assesses the availability of education and the nutritional status of respondents on these two schemes.

Neither the availability of formal schooling nor extension work is satisfactory. The situation regarding primary education has improved over the last few years and almost every child in the survey area goes to school. This seems to be an indication of changing attitudes among parents, increased money available for schooling, as well as greater financial commitments from the Government. However, informal training through extension is carried out only on an irregular basis.

An assessment of the frequency of consumption of various foodstuffs suggests an emphasis on carbohydrates at the expense of proteins, minerals and vitamins. Villagers interviewed indicated that food is in short supply and that allocation of additional land could assist in overcoming these shortages.  相似文献

According to the author, a successful leadership change should not be left to chance. Such a transition must be planned and carefully managed.  相似文献

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.

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
