We define and explore the notion of a Dynamic Condorcet Winner (DCW), which extends the notion of a Condorcet winner to dynamic settings. We show that, for every DCW, every member of a large class of dynamic majoritarian games has an equivalent equilibrium, and that other equilibria are not similarly portable across this class of games. Existence of DCWs is guaranteed when members of the community are sufficiently patient. We characterize sustainable and unsustainable outcomes, study the effects of changes in the discount factor, investigate efficiency properties, and explore the potential for achieving renegotiation-proof outcomes. We apply this solution concept to a standard one-dimensional choice problem wherein agents have single-peaked preferences, as well as to one involving the division of a fixed aggregate pay-off.  相似文献

We examine the interaction between internal control assessments and substantive testing in a model of fraud detection. The purpose of our study is to examine a two‐stage model of the auditor‐manager interaction in which the auditor assesses the “likelihood” or possibility of fraud in the first stage and conducts substantive tests in the second stage. We examine the allocation of audit resources across these two distinct facets of the audit. We find that, regardless of the auditor's allocation, the probability of undetected fraud remains the same, but the allocation of some audit resources to internal control assessment may provide cost savings for the auditor.  相似文献

The domain and theories of marketing have been expanding since the origins of the discipline. Since the 1970s marketing science has been organized around the exchange paradigm. Marketing concepts apply to all forms of exchange, whether it is goods, services, personages, places or ideas, and whether it is between individuals, for-profit and nonprofit firms, governments and NGOs. Marketing theories evolved from a firm oriented view to encompass the exchanging dyad. More recently the paradigm expanded to a network level of explanation, and relational theories have come to the fore. But even as the field struggles to grasp its new fields of explanation, there is a Kuhnian shift happening at its boundaries. The shift significantly bends the marketing worldview as well as the theoretical tools and methodologies we use to study it. In this paper we develop a three-tiered explanation of the emerging field of marketing—its subphenomena (consumer experiences and sensory systems), its phenomena (marketing networks), and its superphenomena (sustainability and development).  相似文献

Product management is one of the most important functions in marketing. Yet the product management literature has focused largely on creating successful products and has relatively little to say about creating effective product management organizations. This paper focuses on the organizational determinants of high‐performance product management at three levels: (1) the product manager as an individual; (2) the marketing processes related to product management; and (3) the organization structure and role definition. The paper identifies several key factors that potentially impact product management performance. A set of qualitative interviews is conducted to develop hypotheses related to constructs that may drive product management performance. These hypotheses are used to develop a causal model for product management performance that includes constructs related to roles and responsibilities, organization structure, and marketing processes related to product management. An empirical survey of 198 product managers from a variety of industries is conducted to test the causal model. The results of the causal model suggest that performance of a product management organization is driven by structural barriers in the organization, the quality of marketing processes, roles and responsibilities, and knowledge and competencies. The findings suggest that structural boundaries and interfaces are the biggest impediment to effective product management, followed by clarity of roles and responsibilities. The research highlights the importance of organization structure and effective human resource practices in improving product management performance.  相似文献

Perceived insecurity in the public space: Personal, social and environmental variables. This paper explores perception of insecurity among the users of Barcelona’s public space. It describes the results of a research aimed to determine the key variables for the understanding of subjective insecurity. Structural equation models have been applied for this purpose. Results show low relative indices of causality for environmental variables, whereas those related to space representation, residential satisfaction and urban identity, social support and personal competences offer high predictive potential. It is concluded that insecurity perceptions in the public space are therefore strongly linked to social interaction processes and to the social construction of insecurity. Other results, like the influence of gender or age, are consistent with previous findings.  相似文献

We identify finance professors’ opinions on the efficiency of the stock markets in the United States and assess whether their views on efficiency influence their investing behavior. Employing a survey distributed to over 4,000 professors, we obtain four main results. First, most professors believe the market is weak to semi-strong efficient. Second, twice as many professors passively invest than actively invest. Third, our respondents’ perceptions regarding market efficiency are almost entirely unrelated to their trading behavior. Fourth, the investment objectives of professors are, instead, largely driven by the same behavioral factor as for amateur investors–one's confidence in his own abilities to beat the market, independent of his opinion of market efficiency.  相似文献

The paper extends Marx's law of value to include the effects of risk. It shows how risk has its origins in the labour process and is transferred between labour and capital on an unequal basis and between capitals on a zero sum basis. An empirical test is then presented, which shows that the employment of labour increases risk from the point of view of the investing capitalist. The conclusion is that the employment of labour is a curate's egg from capital's point of view. On the one hand it is essential for the production of sustainable surplus value and therefore for competitive advantage and capital accumulation. On the other hand employment of labour renders such accumulation inherently risky and therefore commensurately more costly to the rational capitalist investor.  相似文献
