Let χ be a family of stochastic processes on a given filtered probability space (Ω, F, (Ft)t∈T, P) with T?R+. Under the assumption that the set Me of equivalent martingale measures for χ is not empty, we give sufficient conditions for the existence of a unique equivalent martingale measure that minimizes the relative entropy, with respect to P, in the class of martingale measures. We then provide the characterization of the density of the minimal entropy martingale measure, which suggests the equivalence between the maximization of expected exponential utility and the minimization of the relative entropy. 相似文献

Time inconsistency in monetary policy can be addressed appointing a conservative central banker. But incomplete information about the central banker's preferences impairs the performance of delegation schemes. Firstly, the ensuing ex-ante variability of monetary response lowers welfare. Secondly, partial independence schemes may prove inadequate because reputation — not only legal arrangements — defines the actual degree of independence. The incumbent may exploit his reputation to impose too conservative policies whereas, if he lacks reputation, partial independence forces him to accommodate. As a result, simple rules may be preferred.

Cooperatives are facing the challenge to be competitive in the market, without losing their traditional values of mutuality and democracy. To do that, they need to re‐construct open and participative dialogue with their employees and members based on more democratic forms of communication and engagement. From this point of view, the measurement and communication of sustainability aspects may allow a dialogue to be mobilized with shareholders and stakeholders without losing the attention on competitive factors. Based on these premises, the article analyses the experience of a 5‐year action research project (from 2006 to mid‐2011), carried out within Unicoop Tirreno, an Italian consumers' cooperative, and aimed to implement different tools for sustainability accounting and to embrace a more open dialogue with stakeholders, in particular with employees and members. In this process of change, the tools implemented for sustainability accounting played a key role in supporting the cooperative to reinterpret its own values and in stimulating a new and participative management approach. The results indicate a virtuous circle between the management and measurement of cooperative principles and the management and measurement of sustainability issues. 相似文献

The study of French bankruptcy archives has resulted in extensive research into the 18th and 19th centuries. No synthesis has been completed yet. A preliminary review of the literature on the subject is presented here, focusing on three stages: the archives, the statistics, and the data utilization. 相似文献

This article addresses the question of how individual media users, who are part of a mass media audience, perceive their co-audience. We approached this question from an empirical social scientific communication research perspective by introducing a theoretical model of (situational) audience conceptions that might arise in the context of an anonymous, imperceptible mass audience. According to the model, both subjective media theories held by people and cues from the media content influence the users’ impression formation about their anonymous co-audience during media consumption. Audience conceptions would include assumptions on size, simultaneity, social structure and the experience of other consumers. We assume that, as soon as conceptions of the co-audience are formulated, they could influence cognitive and affective aspects of a person’s reception experience. The model states that the more the conception of the audience is salient in a viewer’s mind the stronger its influence on subsequent experiences will be. Possible effects on reception phenomena including social comparison processes and feelings of embarrassment are discussed exemplarily to illustrate fields the model could be fruitfully applied to. Finally, the concept of audience conception is illustrated in a model and brought into context with existing research. 相似文献

We propose a model of portfolio selection under ambiguity, based on a two-stage valuation procedure which disentangles ambiguity and ambiguity aversion. The model does not imply “extreme pessimism” from the part of the investor, as multiple priors models do. Furthermore, its analytical tractability allows to study complex problems thus far not analyzed, such as joint uncertainty about means and variances of returns. 相似文献

Many studies highlight the challenges facing incumbent firms in responding effectively to major technological transitions. Though some authors argue that these challenges can be overcome by firms possessing what have been called dynamic capabilities, little work has described in detail the critical resources that these capabilities leverage or the processes through which these resources accumulate and evolve. This paper explores these issues through an in‐depth exploratory case study of one firm that has demonstrated consistently strong performance in an industry that is highly dynamic and uncertain. The focus for the present study is Microsoft, the leading firm in the software industry. The focus on Microsoft is motivated by providing evidence that the firm's product performance has been consistently strong over a period of time in which there have been several major technological transitions—one indicator that a firm possesses dynamic capabilities. This argument is supported by showing that Microsoft's performance when developing new products in response to one of these transitions—the growth of the World Wide Web—was superior to a sample of both incumbents and new entrants. Qualitative data are presented on the roots of Microsoft's dynamic capabilities, focusing on the way that the firm develops, stores, and evolves its intellectual property. Specifically, Microsoft codifies knowledge in the form of software “components,” which can be leveraged across multiple product lines over time and accessed by firms developing complementary products. The present paper argues that the process of componentization, the component “libraries” that result, the architectural frameworks that define how these components interact, and the processes through which these components are evolved to address environmental changes represent critical resources that enable the firm to respond to major technological transitions. These arguments are illustrated by describing Microsoft's response to two major technological transitions. 相似文献
