The problem of long-range planning and investment project evaluation is complicated by the presence of multiple conflicting goals measured in incommensurable units, indivisibility of alternative projects, and the desire of management to consider mutually exclusive marketing-pricing strategies. The model proposed in this study attempts to allow for these complexities through the use of integer goal programming. It is the hope of the authors that this model will provide management with an additional decision-making tool for implementation of multiple corporate objectives. 相似文献

Several studies extend the Rothschild–Stiglitz model of competitive insurance contracting with adverse selection by incorporating additional dimensions of private information and conclude that some insurers may earn positive profit in a separating, self-selection equilibrium, provided each insurer is restricted to making a single contract offer. The main result of this article is that these profitable configurations are not sustainable when individual insurers can offer multiple contracts. It is also shown that the ability to offer multiple contracts overturns equilibria that have applicants from different risk classes pooled as well as those where profits are dissipated by a fixed entry cost. 相似文献

Hartley Withers' classic book, The Meaning of Money , sees its centenary this year. Although the financial landscape has substantially changed since 1909, Withers' book remains insightful, informative and readable. A symposium is being held in late 2009 to explore what echoes can be heard today. 相似文献

This paper investigates the relationship between subjective expectations regarding the replacement rate of income at retirement and several measures of pension satisfaction. We use panel data on Dutch employees, analyzed with fixed effects models, allowing for correlation between unobserved heterogeneity in satisfaction and optimism or pessimism in expectations. The level of the expected replacement rate is found to be positively related to satisfaction: respondents who revise their expectations of the level of their replacement rate upwards tend to become more satisfied with their pension provisions, in particular with the level of the expected benefits. We do not find robust evidence for a relationship between uncertainty and pension satisfaction. 相似文献

Bundled coverage of different losses and distinct perils, along with differential deductibles and policy limits, are common features of insurance contracts. We show that, through these practices, insurers can implement multidimensional screening of insurance applicants who possess hidden knowledge of their risks, and thereby reduce the externality cost of adverse selection. Competitive forces drive insurers to exploit multidimensional screening, enhancing the efficiency of insurance contracting. Moreover, multidimensional screening allows competitive insurance markets to attain pure strategy Nash equilibria over a wider range of applicant pools, resolving completely the Rothschild–Stiglitz nonexistence puzzle in markets where the perils space is sufficiently divisible. 相似文献

We construct an industry-equilibrium model in which it is costly for consumers who have previously purchased from one firm to switch to competitors. This gives firms a certain degree of market power over their established customers. The equilibria we identify under these conditions have the following properties: (1) there is a nontrivial size distribution of firms, although firms are intrinsically identical, (2) larger firms make higher profits, (3) larger firms spend more on R&D, (4) larger firms charge (on average) lower prices, and (5) profits are positively correlated over time. These properties match empirical regularities concerning the manufacturing and retail sectors in the U.S. economy. 相似文献

The paper presents a conceptual model of an integrated management information system for municipal parks maintenance and operations. Research efforts in management information systems are presented in three categories: Business Research, Federally Sponsored Research, and Park and Recreation Systems Research. A case is made for further empirical research, the development of normative models, and evaluative criteria in an attempt to realize the full potential of electronic data processing in parks and recreation. 相似文献

Expected utility theory, which includes estimating the probabilities of uncertain future outcomes, is the classical model for rational economic decision making, and, by implication, rational valuation and financial reporting regulation. In Wittgensteinian terms it is a ‘hinge’ of the language game in which these practices are embedded. When rendered explicit, however, this ‘hinge’ appears to be formally incoherent. The exploration of this problem has consequences for all of our arguments over the epistemological underpinnings of accounting reports – whether realist, representational, constructivist, or otherwise.Arguably, there are two complementary primitive models that underlie real-world probability estimation. Taken together, they generate a version of Goodman's inductive paradox (other versions of which also arise for non-inductive empirical generalisation). This, in its turn, is related to Kripke's paradox, which arises when we try to give behavioural accounts of rule following, and so of participation in a language game.This paper explicates this type of paradox in the context of commercial decision making, and considers its consequences. The existence of paradoxes should render the system that generates them completely incoherent, but (paradoxically …) they seem to be generated by any attempt to give complete accounts of some of the normative fundamentals which underlie linguistic practice – such as truth-telling, validity and rule-following.Whether or not these paradoxes represent a serious threat to the coherence of the empirical or behavioural sciences, it might be objected that commercial decision making methods and financial regulation rarely aspire to the kind of rigour that these disciplines attempt to achieve. Part of the argument of this paper will be that the intelligibility of commercial language suggests an approach to these paradoxes which is not obvious from more traditional philosophical perspectives.The intentionality of belief renders certain belief claims by participants in a shared language game incorrigible (within the game), in the sense that they can be doubted only by doubting the seriousness or quality of participation. If certain statements about rule following and word meaning have this same quality, then there is a way of avoiding the consequences of Goodman's and Kripke's paradoxes, and of sterilising the probability estimation paradox for any playable commercial language game. 相似文献

Communist China, in contrast to Russia and other East European states, has a long tradition of markets. Arthur Seldon welcomes the increasing honesty with which the Chinese Government, under Deng Xaio-Ping (right), is rejecting centralised control. 相似文献
