The alpha‐maxmin model is a prominent example of preferences under Knightian uncertainty as it allows to distinguish ambiguity and ambiguity attitude. These preferences are dynamically inconsistent for nontrivial versions of alpha. In this paper, we derive a recursive, dynamically consistent version of the alpha‐maxmin model. In the continuous‐time limit, the resulting dynamic utility function can be represented as a convex mixture between worst and best case, but now at the local, infinitesimal level. We study the properties of the utility function and provide an Arrow–Pratt approximation of the static and dynamic certainty equivalent. We then derive a consumption‐based capital asset pricing formula and study the implications for derivative valuation under indifference pricing. 相似文献

Amazon Mechanical Turk (AMT) is an online labor market that is being used increasingly often in the social sciences. This occurs despite significant questions regarding efficacy of the platform. In this article, we attempt to address some of these questions by exploring the consistency of the characteristics of individuals who participate in studies posted on AMT. The primary individuals analyzed in this study are subjects who participated in at least two of eleven experiments that were run on AMT between September of 2012 and January of 2018. We demonstrate subjects consistently report their age, gender, subjective willingness to take risk, and impulsiveness. Further, subjective willingness to take risk is found to be significantly correlated with decisions made in a simple lottery experiment with real stakes—even when the subjective risk measure is reported months, sometimes years, in the past. This suggests the quality of data obtained via AMT is not terribly harmed by the lack of control and low stakes. 相似文献

Firms typically present a mixed picture of corporate social performance (CSP), with positive and negative indicators exhibited by the same firm. Thus, stakeholders' judgments of corporate social responsibility (CSR) typically evaluate positives in the context of negatives, and vice versa. Building on social judgment theory, we present two alternative accounts of how stakeholders respond to such complexity, which provide differing implications for the financial effects of CSP: reciprocal dampening and rewarding uniformity. Echoing notable findings on strategic consistency, our US panel study finds that firms that exhibit uniformly positive or uniformly negative indicators in particular dimensions of CSP outperform firms that exhibit a mixed picture of positives and negatives, which supports the notion that stakeholders' judgments of CSR reward uniformity. 相似文献

As emerging economies experience a boom in capital inflows, governments are increasingly concerned about their downsides. Even the IMF (International Monetary Fund), long a stalwart proponent of financial liberalization, has engaged in a new debate on capital flow management. Drawing lessons from empirical case studies on Brazil and South Korea, this paper finds that the new IMF framework remains insufficient in two main aspects. First, by defining ‘capital flow management measures’ (CFMs) as a temporary instrument embedded in an overall strategy of financial opening, the organization insists on the general advantages of financial liberalization, which poses serious limits to emerging economies’ policy space. Second, the Fund keeps on stressing a separation of prudential financial regulation, which should be permanent, and temporary CFMs. Yet, the case studies presented here show that, especially for emerging markets with rather open and sophisticated domestic financial markets, both types of measures are interdependent and overlapping. Additionally, we demonstrate the relevance of a third type of regulation, lying on foreign exchange (FX) derivatives instruments, which may also be required to effectively manage foreign investors’ portfolio reallocations and their impact. 相似文献

In the context of resource allocation on the basis of priorities, Ergin (2002) identifies a necessary and sufficient condition on the priority structure such that the student-optimal stable mechanism satisfies a consistency principle. Ergin (2002) formulates consistency as a local property based on a fixed population of agents and fixed resources—we refer to this condition as local consistency and to his condition on the priority structure as local acyclicity. A related but stronger necessary and sufficient condition on the priority structure such that the student-optimal stable mechanism satisfies a more standard global consistency property is unit acyclicity. 相似文献

Little is known about the satisfaction with employee performance management systems in higher education institutions. In this study, we contribute to this field by focussing on the alignment features of employee performance management systems, on communication related to these systems and on control tightness in the academic unit. An important contribution to the literature is the adoption of an integrated approach to employee performance management in higher education institutions. Employee performance management system features and satisfaction result from a survey to which 589 employees of a Flemish University contributed. Separate estimations are done for different tenure types of academics. The estimation results show that a higher level of internally consistent employee performance management systems, more communication and tighter control are associated with higher academic employee performance management satisfaction. The study also reveals that employee performance management satisfaction depends on the tenure type, suggesting that a diversified employee performance management policy should be considered in universities. 相似文献

There are comparatively many scenarios for equipment replacement in engineering economics. With a view to the unsystematic solutions, a classical case is studied here to demonstrate the inherent consistency in the various evaluation methods for equipment replacement analysis. 相似文献

We show that in dynamic choice problems, the observability of a decision maker's first move does reveal his plan for the dynamic choice problem, only under strong restrictions about the structure of his preferences. These restrictions imply consequentialism which in turn implies dynamic consistency, a condition which is not necessarily satisfied by experimental subjects. 相似文献
