The increase in interconnectivity and developments in technology have caused cyber security to become a universal concern. This paper highlights the dangers of the evolution of cyber risk, the challenges of quantifying the impact of cyber-attacks and the feasibility of the traditional actuarial methodologies for quantifying cyber losses. In this paper, we present a practical roadmap for assessing cyber risk, a roadmap that emphasizes the importance of developing a company and culture-specific risk and resilience model. We develop a structure for a Bayesian network to model the financial loss as a function of the key drivers of risk and resilience. We use qualitative scorecard assessment to determine the level of cyber risk exposure and evaluate the effectiveness of resilience efforts in the organization. We highlight the importance of capitalizing on the knowledge of experts within the organization and discuss methods for aggregating multiple assessments. From an enterprise risk management perspective, impact on value should be the primary concern of managers. This paper uses a value-centric/reputational approach to risk management rather than a regulatory/capital-centric approach to risk.  相似文献

Very many statements have been made about the (non-)existence and characterisation of the ‘marginal revolution’ but it is urged here that detailed study of the relevant texts is far more valuable than the making of grand statements about such matters. In particular, a close reading of Jevons's Theory of Political Economyis proposed as an antidote to over-easy generalisation. Jevons by no means rejected all elements of classical theory. He did not propose a catallatic revolution; he attributed such an emphasis to earlier authors and himself stressed the role of production. It is shown that Jevons was very aware of the necessarily general equilibrium nature of his theory but that he was simply not able to cope with it satisfactorily; it is suggested that this explains, at least in part, his fluctuating and apparently inconsistent statements relating utility and labour to value. Jevons certainly attempted to sketch a complete marginal productivity theory of distribution, even if he was far from successful in providing one.  相似文献

This paper attempts to reconstruct and assess the intellectual itinerary of Hicks on the valuation of social income. His 1958 and 1981 papers on that topic have been wholly ignored in the economic literature. In both of them differentmeasures of real income are provided. These show to what extenteach one of them can be relied upon. Our assessment argues that it is impossible to measure social income independentlyof the reasons for which that measure is required and that any valuation cannot ultimatelybe made independently of political and ethical considerations.  相似文献

投资消费失衡严重制约了我国国民经济持续健康发展,国民收入在企业部门、政府部门、住户部门之间的不合理分配是导致我国投资消费失衡的根本原因。国民收入分配对投资消费失衡影响的数理分析和实证分析表明,对投资率、消费率最有影响的是企业部门在国民收入分配中的比重,其次是政府部门在国民收入分配中的比重,影响最小的是住户部门在国民收入分配中的比重。  相似文献

本文横向解剖了以美国哈佛大学为例的自由教育,纵向分析了教育史上的几个重要时期,同时探讨了人的自由本性;通过对教育自由与人才培养之间关系问题的多角度分析,首次提出了教育的自组织理论。该理论认为:只有独立的、自由的、开放的教育才能够充分发挥其自组织功能,才能够培养出原创性人才;中国的教育要想能够培养出创造性人才,必须改变对人的生命和人的教育以及政治理性与教育理性关系的基本理念。  相似文献

Previous studies have highlighted the question of government loan interest as one of great current importance. Government borrowing levels are high, and reducing interest payments would generate savings to meet other spending needs and/or to lower taxation, thus supporting the sustainability of public finances. However, no previous study has presented a method for a local government to calculate its own credit risk and thus be in a position to negotiate lower interest rates on its borrowing. This article defines a financial model that enables local governments to estimate the interest rate payable on a bank loan, based on their credit risk premium, in accordance with the Basel II rules and the findings of our empirical study of large local governments.  相似文献

Based on the approach developed by Elliott et al. (2005), we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error. Our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil. Accounting for the asymmetry of the loss function does not necessarily make forecasts look rational.  相似文献

The authors detail an urban economics experiment that is easily run in the classroom. The experiment has a flexible design that allows the instructor to explore how congestion, zoning, public transportation, and taxation levels determine the bid–rent function. Heterogeneous agents in the experiment compete for land use using a simple auction mechanism. Using the data that is collected, a bid–rent function is derived, and the experimental treatment is altered over the course of three sessions to uncover core concepts in urban economics. Moreover, this provides a tangible experience that can be used to help undergraduates relate to urban issues such as the steep rent gradient found around many larger colleges and universities.  相似文献

During the 1990s, all of the European transition economies (TE) experienced a major recession and suffered from the explosion of income inequality. However, distribution of income between labor and capital differed greatly from one group of post-communist countries to another. The paper discusses and analyzes linkages between models of capitalism that emerged in former communist countries in the 1990s and the outcome of capitalist transition for labor in terms of income distribution and inequality. It is based on the estimates of the Marxian rate of exploitation and other indicators of labor income performance during the reform period.  相似文献

结合信息技术对中国城市影响的实际,从信息技术影响下城市空间相互作用方式、空间结构的构成要素及其影响因素的变化出发,对信息时代国内城市功能特征进行研究变得尤为重要.全球化、柔性化、复合化、差异化已成为信息时代城市功能的主要特征;信息流和接入信息的能力变得尤为重要;每个城市都成为全球或区域城市网络的一个节点;部分服务的区位选择因此也表现出较大的弹性;城市居住空间分异仍然存在,影响因素越来越复杂.  相似文献
