In this paper social interaction is modeled as a consumer good. A model of household production is employed to derive the demand for social interaction. The model shows that the demand for social interaction is a function of its price, the price of other goods and income. The theory is tested with data from the General Social Survey and the results show that social interaction can be explained as the consequence of utility maximizing behavior by individuals. These results are in contrast to social capital theorists who have attributed these changes to factors such as increased community heterogeneity.  相似文献

文章认为,在现代全球化商品生产环境下,构建生产和再生产的社会关系从普遍意义上讲就是阶级关系,提出应重回阶级视角审视和分析农村贫困及其产生原因。在这一视角下对现代农地变迁进行探讨,并在提出当代农耕变化七个命题的基础上,识别了不同阶层关系下的动力机制和不同发展政策议题下隐含的阶级动力,并指出,现有关于改善农业生产、农村生计和福利的政策忽略了阶级不平等性,因此它们也忽略了贫困的根本社会基础以及不同干预对此带来的重要影响。  相似文献

The present paper deals with the Galbraithian theory of the managerial firm. Galbraith has stressed corporate size and has questioned the effectiveness of the market demand, technology and capital market constraints, which in conventional theory restrict the size of the firm.Galbraith represents the objectives of the corporation in terms of a conventional lexicographic objective function with some minimal level of profits (in terms of cash flow) being ranked the dominant objective. Also in his treatment of the corporate constraints, Galbraith does not move much beyond the current state of knowledge. The assumption of consumer sovereignty has long been relegated to the text-book literature, and the firm's control over the quality of its product (its price elasticity) has been generally recognized. Similarly, it has been known that the capital market is not perfect so that it is unlikely to constrain the expansion of the firm with some given investor determined earning constraint. In his attempt to show the technostructure's ability to plan the rate and the direction of the technological development Galbraith did not, however, meet with wide support from empirical research and analysis. It is extremely difficult to test the firm's control over its production technology, and while the few industry studies available can hardly be used to reject the Galbraithian position, there is not sufficient evidence to support a generalization of Galbraith's conjecture.While individually these constraints have been analyzed and discussed in the literature, Galbraith has combined these results and has been able to show that in the industrial state the qualitative laws of economic common sense do not hold. The importance of this conclusion is not only academic. Efforts to control corporate allocations through rate controls, antitrust litigation, and in other ways emanate from the conventional theory of firms and markets and do not fit the industrial state. In this state corporate size does matter and cannot be treated as random: The larger the corporation the more perfect the control it assumes over its environment and the higher the efficiency with which it plans its over-all operations.We acknowledge the helpful comments of a referee of this journal.  相似文献

Over the last 40 years, the Sahel has seen a long-term downward trend in rainfall. The importance of ecological variables as factors affecting child survival in rural subsistence societies has already been emphasized, but little empirical evidence has been gathered to support this. This paper presents a comparative event history analysis aimed at understanding how rainfall variations may influence child mortality in two neighbouring countries, Burkina Faso and Mali. These countries are similar in terms of population dynamics, economy, livelihood, child mortality and rainfall conditions (i.e. strong south–north decreasing rainfall gradient). Individual data for both countries came from two detailed nationally representative retrospective surveys conducted in 2000. Rainfall data for the 1960–1998 time period were obtained from the Climatic Research Unit. This study shows that child survival in each country is related to specific patterns of rainfall variation across livelihood regions, highlighting the complex nature of environmental causality of child mortality.  相似文献

People lie on a frequent basis. However, when a victim of maltreatment lies by denying the abuse, lies can become forensically relevant. We have reviewed the relevant literature on the prevalence and memory consequences of such false denials. The way forensic interviewers proceed in the face of denying children will be shaped by their beliefs about the frequency with which truly abused children deny abuse. We discuss that estimates of the prevalence of false denials among abused children vary but that such false denials do happen. When falsely denying children eventually come forward with their experiences, a second issue lingers: how valid are maltreated children's statements after a false denial? We review the literature indicating that false denials can negatively affect memory for the investigative interview during which the lie was told. Yet, memory for the denied experience itself seems to be mostly preserved, and some research even found potential protective effects of false denials. We conclude that denials should always be handled with care in the court room, since the ground truth usually is not known, but that statements should not be dismissed based solely on previous denials.  相似文献
