Every successful communication process requires a certain degree of self-disclosure. However, both in real life and on social network sites like Facebook, self-disclosure does not imply a total sacrifice of privacy. People rather tend to disclose one part of the self while keeping another one protected. In doing so, it is less important where the protective line is drawn, but that a line is drawn at all. This basic principle of conditional self-disclosure can be applied in diverse strategies. An online survey among German Facebook users (n = 684) examined this assumption. Items for a scale of subjective privacy regulation were derived from Burgoon’s four dimensions of privacy. Based on user’s varying emphasis on these privacy dimensions, seven different types of privacy management could be distinguished. Among these, six different strategies of conditional self-disclosure were observed (?chatty“, ?blogging“, ?networking“, ?sorting“, ?passive“, and ?inexperienced“). Only ?careless“ users did not follow our expectations, attaching none of the measured protective conditions to their self-disclosure. 相似文献

When the subprime crisis started to emerge, collateralized products based on credit default swap (CDS) exposures combined with security features seemed to be a more rational alternative to classic asset backed securities. Constant Proportion Collateralized Debt Obligations (CPDOs) are a mixture of Collateralized Debt Obligations (CDOs) and CPPIs with inverse mechanism. This new asset aims at meeting the investors’ demand for credit derivatives with security enhancements, but to our knowledge quantitative approaches for pricing other than simulation algorithms do not exist yet. CPDOs became famous notably by Standard & Poor’s rating model error which illustrated that closed-form analytical pricing is necessary in order to evaluate and understand complex derivatives. This article aims to shed a light on CPDOs’ specific structural enhancements and mechanisms. We quantify inherent risks and provide a dynamic closed-form pricing formula. 相似文献

AbstractI investigate how different legal regimes affect auditor's effort and investors' investment decisions when the auditor is subject to probability weighting and loss aversion, which are two important characteristics of Prospect Theory. Probability weighting encourages an auditor to overrate the audit risk and the likelihood of damages leading to inflated audit fees which could help to explain the BigN audit-fee premium. With loss aversion, an auditor is sensitive to the risk of damage compensation and, thus, tends to exert excessive caution which also generates excessive audit fees. Consequently, investors may choose not to hire an auditor and, as a result, may forego an otherwise profitable investment. These effects are more intense with a strict liability regime than with a negligence rule because with the latter, the auditor is not held liable when due care has been exerted. This removes the risk of incurring losses. The paper highlights the robustness of the negligence regime when preferences are unobservable. 相似文献

The supply of and demand for accounting information 总被引:2,自引:0,他引:2
The article analyzes the use of accounting information in Russia. We assess reporting behaviour in the lending process for a sample of Russian companies in the years 1999–2004 and postulate that Russian companies manage their earnings in order to avoid showing losses when applying for bank financing. Once a credit has been granted, companies are predicted to manage earnings because of the bank's monitoring activities. By means of univariate and multivariate analysis we are able to attribute the discontinuity around a zero target in the earnings distribution with firms’ response to the banks’ assessment of accounting performance. This implies that financing considerations affect the reporting incentives of Russian companies. 相似文献

Previous research has shown that formal networks can play a crucial role in the formation of technological innovation systems (TIS). Firms and other actors collaborate in formal networks not only to generate new knowledge but also to strategically create and shape supportive system resources such as technology specific R&D programs. This paper takes a closer look at the resources, which are developed and deployed by networks to facilitate the building up of a TIS. Networks rely not only on the organizational resources of their members but also on new resources developed at the network level including network governance structures, trust among network members, a common understanding of the strategic goals or a good reputation of the network. Our analysis shows that the capacity of networks to fulfill different tasks of system building especially depends on the network resources they are able to establish. With the differentiation of organizational, network and system resources we introduce a conceptual framework, which makes three important contributions. It highlights the strategic nature of (innovation) system building; it allows us comparing the contribution of different actors and formal networks in this regard; and it improves our understanding of how firm and system level processes are intertwined. 相似文献

We consider kernel density estimation for univariate distributions. The question of interest is as follows: given that the data analyst has some background knowledge on the modality of the data (for instance, ‘data of this type are usually bimodal’), what is the adequate bandwidth to choose? We answer this question by extending Silverman's idea of ‘normal‐reference’ to that of ‘reference to a Gaussian mixture’. The concept is illustrated in the light of real data examples. 相似文献

This paper analyses the international management control (IMC) system that Japanese multinational companies (MNCs) employ to co-ordinate the activities of their subsidiaries in China. It focuses on the role of Japanese expatriates in this IMC system and assesses their performance. In the process, it offers a comprehensive evaluation of the organizational fit of the Japanese IMC model within the current Chinese business environment. Taking Japanese firms as the subject, the analysis identifies areas of incongruity and explains the underlying reasons for problems with expatriate-focused IMC models. In doing so, this paper argues that the Japanese expatriate-based control system in China (as in many other parts of the world) continues to be characterized by an insider-outsider mentality that prevents a real internationalization of overseas operations in the 'transnational' sense. 相似文献
