The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments. JEL Classification C90, C91, D90, D91, D11, D12  相似文献

The authors extend the literature on the efficacy of high school economics instruction in two directions. First, they assess how much economic knowledge that California students acquired in their compulsory high school course is retained on their entering college. Second, using as a control group some college students from the state of Washington, where there is no mandate for high school economics instruction, the authors evaluate the impact of California's high school economics mandate on students’ economic literacy when they enter college. The testing instrument is the Test of Economic Literacy (TEL).  相似文献

The channel literature has paid little attention to issues related to exclusive dealing governance arrangements. Consequently, there is only limited knowledge about how exclusive dealing impacts various channel processes and outcomes. This gap is especially regrettable since exclusive dealing, in addition to being one of the most commonplace governance formats within the distribution channels, is also one of the best exemplars of viable unilateral governance formats. In this initial investigation, the authors explore the linkages among the constructs of exclusive dealing, relationalism, communication, and performance. Empirical data for the study were drawn from the photocopier industry. He obtained his M.B.A. and D.B.A. degrees from Boston University. His primary research interest includes channels of distribution, franchisor-franchisee relationships, and consumer purchase behavior in international contexts. He has published articles inJournal of Marketing Channels and the proceedings of several marketing conferences. This article was crafted when Rajiv Dant was at Boston University. He received his M.B.A. from Bombay University and his Ph.D. from Virginia Polytechnic Institute and State University. His research focuses on channels of distribution, with primary emphasis on franchise structure, franchisee-franchisor relationships, and public policy aspects of franchising growth and ownership topics. His research has been published inJournal of Marketing, Journal of Public Policy & Marketing, Research in Marketing, Journal of Retailing, Journal of Business Research, Journal of Business Venturing, Journal of the Operations Research Society, Marketing Letters, Journal of Small Business Management, Journal of Economic Psychology, Southern Business & Economics Journal, Philosophical and Radical Thought in Marketing, Journal of Healthcare Marketing, Journal of Marketing Channels, andInternational Small Business Journal.  相似文献

The authros examine from the perspective of marketing professionals the incidence of unethical research practices and the influence of organizational factors as determinants of the incidence of unethical research practices. The results indicate some degree of indicence of unethical research practices, particularly of those involving respondents. In addition, the results suggest four organizational variables— extent of ethical problems within the organization, top management actions on ethics, organizational role, and industry category—as determinants of the incidence of unethical research partices.  相似文献

Market share plays a central role in a number of portfolio planning models. This article presents an exposition of the underlying relationship between market share, market size, market growth rate, product sales volume and product sales growth rate. Three constructs—the market share multiplier, the physical volume multiplier, and the dollar volume multiplier—which aid in the strategic analysis of the product portfolio are proposed. The linkages between inter-related growth constructs such as the volumetric and dollar sales growth rate, and the nominal and real dollar sales growth rate are discussed. Certain generalizations regarding market share and its sensitivity to various environmental conditions are highlighted.  相似文献

In this study, we provide empirical evidence on whether voluntarily disclosed causal attributions made in management earnings forecasts are credible by investigating the conditions under which such attributions are made and the extent to which security price responses are associated with attribution existence. We find that causal attributions are more likely to be made when forecast news is bad (relative to good), and that the type of attribution made is more likely to be external (internal) for bad (good) forecast news. Incorporating the existence and type of attribution into models that explain announcement period three-day cumulative abnormal returns yields significant effects for attribution incidence and type after controlling for unexpected earnings and forecast type (e.g., point, range, etc.). Consistent with the idea that attributions enhance the credibility or precision of management forecasts, attribution disclosure enhances price reactions per dollar of unexpected earnings conveyed in a management forecast.  相似文献

We examine how governance characteristics are related to the corporate choice between public and private debt. We find that firms with fewer takeover defenses and larger outside blockholder ownership are more likely to borrow from banks and to issue 144A debt. We also document that public debt cost is more sensitive to takeover exposure than bank debt cost. These results are consistent with the hypothesis that banks mitigate the expected negative effect of takeovers on debt value through covenants and debt renegotiations. Moreover, we show that firms with weaker internal monitoring are less likely to borrow from banks.  相似文献

The early organisation of accountants in Scotland during the 1850s and 1860s has excited the intellectual curiosity and research endeavour of a number of students of professionalisation. By contrast, until recently there was a dearth of academic interest in institutional developments in England and Wales during the 1870s and 1880s. Yet, organisations such as the Institute of Chartered Accountants in England and Wales (ICAEW) which emanate from this period soon became the most significant players on the British professional scene and were to exert considerable influence on the development of accountancy institutions and professional ideologies in several locations. Exploiting a variety of genealogical sources this paper seeks to fill a void in the literature by analysing the social origins of the founding members of the principal professional association in England and Wales. It provides evidence of early chartered accountancy as a destination for long distance, upwardly mobile males, both intergenerationally and intragenerationally. The rate of self-recruitment among the founders of the ICAEW is shown to be low. The proportion of founders deriving from the upper and upper-middle classes is revealed to have been markedly less than that of their Scottish counterparts. The paper contributes to understandings of the complex professionalisation of British accountants, the extent of social mobility in Victorian Britain, the pathways to social advance in a class-based society, and illuminates the social complexion of one of the ‘new’ professions which emerged during the nineteenth century.  相似文献

Although data collection in conjoint analysis has traditionally involved the use of in-person interviews, recent years have seen a trend toward the use of alternative data collection modes, including mail questionnaires and telephone interviews. Since these alternative modes differ in environment, the author examines the predictive performance of conjoint models under three data collection modes, i.e., in-person interviews, mail questionnaire, and telephone interviews. The results indicate the conjoint models examined to be comparable in predictive, performance across the three data collection modes.  相似文献

This study tests and contrasts the ability of multidimensional scaling (MDS) and nonlinear mapping (NLM) in recovering complex data structures in attribute space, and aiding researchers and practitioners in making neighborhood interpretations. The relative merits of both MDS and NLM for product positioning are explored and discussed. A formal comparison of the performance of NLM versus MDS is presented using both simulated and actual data. The results of this study provide direction as to the conditions under which a nonlinear mapping algorithm is preferable over MDS.  相似文献
