An examination of the ethical perceptions of business students using Macobby's head/heart traits and a comparison to earlier studies of managers, accountants, and business students is made. The data were collected at three universities that are similar in size, enrollment and degree programs within the College of Business. Results indicate that present day business students are no less ethically inclined than are their business counterparts in previous eras. In general head traits dominated over heart traits, an indication that business schools continued to do a good job emphasizing and developing analytical skills but a poor job of developing the qualities of the heart that are generally associated with ethical behavior. The implications of these findings are discussed. 相似文献

Gillian S. Morris 《Journal of Consumer Policy》1994,17(2):147-158
This paper discusses the revolutionary new right introduced by the Trade Union Reform and Employment Rights Act 1993 for consumers to seek a court order to halt unlawful industrial action which disrupts the supply of goods or services, regardless of whether they have any enforceable right to the goods or services in question. Even more unusually, public funding is available to conduct these proceedings irrespective of the applicant's means where the industrial action is organised by a trade union. The paper analyses the nature of the right, locates it within the broader framework of remedies for the non-provision or inadequate provision of goods or services, and assesses the wider implications of the right for consumer policy. 相似文献

This paper is concerned with one central question: the choice between theories, and the role played by data in that choice. It deals with the uses economists may make of data and the importance of understanding the institutional basis that gives rise to the data - an area in which labour economists have traditionally been particularly strong - and with the relevance of assumptions. It deals with the ultimate need to choose between competing theories (despite the role of conventionalism) on the basis of data rather than retreating into a comfortable 'methodological pluralism'. It considers the role of test replication, with reference to the practice in natural science (and its role there in checking scientific fraud) and concludes that, despite extensive technical problems of testing, economists have to accept a data check if the rhetoric of mathematical technicality is not to overwhelm the need to explain. Parallels are drawn with experience in physics (and the implications of the development of Chaos and Catastrophe for a naively predictionist view are noted), medicine and history (of which, it is argued, modern economists are far too neglectful). 相似文献

The feminization of poverty refers to female householders and their children becoming an increasing percentage of the poor
population. After examining effects of race on poverty of female-headed households from 1959 to 1989, this study investigates
statistical relationships among female poverty, economic and labor market conditions, and transfer payments (specifically
AFDC) by means of the Granger causality test over the period from 1966 to 1988. This study reinforces the plausible assumption
that policies which would lower the unemployment rate of females and would increase real economic growth could be expected
to reduce the number of poor female households. 相似文献

The number of intermediary levels between a manufacturer and the final market in a distribution channel varies from industry to industry. In some cases, none are used (i.e. the distribution function is vertically integrated), while several middleman levels are used in other cases (e.g. the use of a wholesaler, a jobber, and a retailer in the distribution of meat). In this paper we examine the effect of competition on the profit-maximizing length of the distribution channel. We find that the optimal number of middleman levels increases with the substitutability of products in the market, but that there are institutional limits on the maximum number of levels in a channel. The analysis also suggests that differences in the objectives of channel members (e.g. the maximization of total channel profit versus the maximization of each member's individual profit) affect optimal channel length: a goal of total channel profit maximization produces a channel at least as long as one of individual (non-co-operative) member profit maximization. The work thus complements existing research focusing on intra-channel (e.g. cost-based) explanations of channel length, using a framework similar to those investigating competitive incentives for vertical integration in distribution. 相似文献

In this paper we offer a method for deciding how to aggregate a set of elementary industries. The method is then applied to the problem of estimating a wage equation that allows for industry-specific effects. Our method explicitly formalizes the trade-off between goodness-of-fit and parsimony implicit in an aggregation problem. By varying the parameter of the assumed loss function, one obtains a whole sequence of aggregation levels. Further, the resulting sequence is consistent; that is, groupings formed at one level of aggregation will never be undone when one aggregates further. 相似文献

This article analyses the effects of action aimed at narrowing the gap between South Africa's ‘two agricultures’, specifically the effects of the Farmer Support Programme (FSP) on structural aspects of maize production under different marketing policies. This is done by assembling a sectoral linear programming model of the South African summer-rainfall grain-producing area. The emphasis is on the inclusion of supply, demand and production risk. Results show that the effects of a successful FSP on specific interest groups, e.g. consumers of a specific product, or producers in a specific region, depend on the marketing policy followed, as well as on the effectiveness of the FSP. The analysis accentuates the interrelationships in South African crop production and illustrates how past policies ignored regional comparative advantages, distorted regional development and affected social welfare. 相似文献

The 1992 Horizontal Merger Guidelines of the Department of Justice and the Federal Trade Commission outline an enforcement policy which makes a long overdue break with its predecessors in awarding no decisive or predominant role to market concentration as a criterion of anticompetitive effect. However, the new policy does not provide an adequate substitute criterion: the tests that it prescribes for screening merger proposals are so specified that a potentially large proportion of anticompetitive mergers can escape challenge without showing any promise of improving efficiency. The time is ripe for a comprehensive inquiry aimed at formulating a more satisfactory policy. 相似文献

Our examination of the cross-section of expected returns reveals economically and statistically significant compensation (about 6 to 9 percent per annum) for beta risk when betas are estimated from time-series regressions of annual portfolio returns on the annual return on the equally weighted market index. The relation between book-to-market equity and returns is weaker and less consistent than that in Fama and French (1992). We conjecture that past book-to-market results using COMPUS-TAT data are affected by a selection bias and provide indirect evidence. 相似文献
