This paper offers a critique of the cordon approach to flood control that Bangladesh has been pursuing for several decades now. It shows how this approach fails to solve the flood problem, deprives the floodplains from benefits of regular river-inundation, creates a risky situation for the inhabitants inside cordons, brings in new problems of drainage and sanitation, and leads to huge waste of resources. The paper then argues for the open approach to flood control as the way to the future. The main components of this approach are: re-excavation of river beds and other surface water bodies, minimization of obstruction on floodplains, increasing the elevation of rural and urban dwellings, restoration of waterways, and promotion of rural settlement consolidation around permanent flood shelters. The paper shows in what ways the open approach to flood control is superior to the cordon approach. 相似文献

There is a lack of actors and governance in backcasting studies. Given that such studies typically are used to explore and promote change, the absence of change agents and their institutions is a shortcoming. This paper presents four approaches to include actors and governance as objects of study in backcasting studies; the stakeholder analysis approach, the social network approach, the governance model approach, and the policy and change approach. In the paper a scenario study of the greening of private transport in Bromma, Stockholm is used as example. 相似文献

This paper provides a unified approach for pricing contingent claims on multiple term structures using a foreign currency analogy. All existing option pricing applications are seen to be special cases of this unified approach. This approach is used to price options on financial securities subject to credit risk. 相似文献

This paper discusses the relative merits of the two approaches of financial regulation and supervision for the case of Latin America and the Caribbean (LAC). In doing so, it reviews the main arguments advanced in the specialized literature in pro and against of each approach. All the theoretical arguments are contrasted with available country experiences from around the world and discussed with a focus on the Latin American and Caribbean countries. A methodology to analyze the efficacy and the efficiency of each approach in meeting the main objectives of financial regulation is also provided. The paper concludes that in the present circumstances, the net benefits of adopting an integrated approach probably exceed the net benefits stemming from the adoption of a specialized approach for most of the countries in the region. 相似文献

ABSTRACTThis paper presents a new and widely applicable nonparametric approach to the characterisation of time series dynamics. The approach involves analysis of the incidence of occurrence of patterns in the direction of movement of the series, and may readily be applied to time series data measured on any scale. The paper includes derivations of analytic forms for two (infinite) families of distributions under the null hypothesis of random behaviour, and of a useful analytic form for the generation of the moments of these distributions. The distributions are asymptotically normal, so allowing for straightforward application of the approach presented in the paper too long series of high frequency and/or extended time period data. Areas of application in finance and accounting are suggested. 相似文献

In this paper, we employ the stochastic dominance (SD) approach to rank the performance of commodity trading advisors (CTA) funds. An advantage of this approach is that it alleviates the problems that can arise if CTA returns are not normally distributed by utilizing the entire returns distribution. We find both first-order and higher-order SD relationships amongst the CTA funds and conclude that investors are better off investing in the first-order dominant funds to maximize their expected utilities and expected wealth. However, for higher-order dominant CTAs, risk-averse investors can maximize their expected utilities but not their expected wealth. In addition to the advantages of the SD approach in the case of non-normal returns, the paper concludes that the approach is more appropriate compared with traditional approaches as a filter in the CTA selection process as it provides meaningful economic interpretation of the results. 相似文献

This paper illustrates how a misclassification cost matrix can be incorporated into an evolutionary classification system for bankruptcy prediction. Most classification systems for predicting bankruptcy have attempted to minimize misclassifications. The minimizing misclassification approach assumes that Type I and Type II error costs for misclassifications are equal. There is evidence that these costs are not equal and incorporating costs into the classification systems can lead to better and more desirable results. In this paper, we use the principles of evolution to develop and test a genetic algorithm (GA) based approach that incorporates the asymmetric Type I and Type II error costs. Using simulated and real-life bankruptcy data, we compare the results of our proposed approach with three linear approaches: statistical linear discriminant analysis (LDA), a goal programming approach, and a GA-based classification approach that does not incorporate the asymmetric misclassification costs. Our results indicate that the proposed approach, incorporating Type I and Type II error costs, results in lower misclassification costs when compared to LDA and GA approaches that do not incorporate misclassification costs.

This paper develops an unconditional and conditional extreme value approach to calculating value at risk (VaR), and shows that the maximum likely loss of financial institutions can be more accurately estimated using the statistical theory of extremes. The new approach is based on the distribution of extreme returns instead of the distribution of all returns and provides good predictions of catastrophic market risks. Both the in-sample and out-of-sample performance results indicate that the Box–Cox generalized extreme value distribution introduced in the paper performs surprisingly well in capturing both the rate of occurrence and the extent of extreme events in financial markets. The new approach yields more precise VaR estimates than the normal and skewed t distributions. 相似文献

One of the fundamental issues in the discussion of auditors' liability is to whom auditors should be held liable for ordinary negligence under common law. Three judicial viewpoints prevail: the restrictive privity approach, the more liberal Restatement approach, and the most liberal foreseeability approach. To compare these three approaches from an efficiency perspective, this paper develops a model that features an owner-managed firm, an independent auditor, a continuum of unrelated lenders, and an impartial court. Double effort-incentive problems appear for the firm and the auditor. The firm has an additional incentive problem due to the sequential nature of its borrowing. This paper shows that the effort-incentive problem and the sequential borrowing problem of the firm render unambiguous improvements in audit effort/quality, capital investment, and social welfare as the judicial approach governing the scope of auditors' liability becomes more conservative. 相似文献

This paper presents a new approach to the optimisation of direct mail offers. Conjoint measurement will be used to identify two aspects of an offer: the degree of interest; and the speed at which an individual processes the information. The approach allows the marketer to create offers that are simultaneously attractive to customers and easy to understand. The approach is illustrated by a credit card case study. 相似文献

In the context of recommending and implementing change in accounting education, the role played by the evaluation of accounting programs cannot be ignored. In fact, program evaluation and continuous improvement are also a critical accreditation requirement of the AACSB. While accounting curriculum reviews, standardized examinations, portfolio analysis, student surveys, alumni surveys, employer\recruiter surveys, and interviews, discussions and observations are important, they are not the only means of evaluating accounting programs. The objective of this paper is to propose and illustrate the factor-analytic approach as an addition to the existing arsenal of evaluation methods. This approach, which uses examination results, can add a new, objective and empirical dimension and make the evaluation more comprehensive. This paper explains the rationale for and presents the proposed factor-analytic approach to evaluating accounting programs. It also illustrates the application of the proposed approach via a Singapore case study. Finally, limitations of the proposed factor-analytic approach to evaluating accounting programs are discussed, with suggestions for future research. 相似文献

In this paper, four case studies of retail financial services companies involved in Internet marketing of their services are investigated. The approaches taken range from a fully integrated approach, a stand-alone approach separate from the mainstream of the company's business, an experimental approach and an approach that can only be described as ‘reluctant’. The cases demonstrate the critical role of senior management, the possible limitations of market intelligence as a guide to action, the need to focus on resources and capabilities, and the requirement for creativity in strategy. 相似文献

The literature on conditional event studies advocates the use of endogenous switching models to analyze cross-sectional variation in the stock market's response to corporate announcements of endogenous events. This paper proposes the use of a flexible Bayesian Markov chain Monte Carlo (MCMC) approach for estimating such models. The Bayesian MCMC approach offers several advantages over the Heckman–Lee two-stage estimation approach. In particular, analysis of the “treatment effect” (the difference between the observed and counter-factual outcomes) controls for the endogeneity of the firm's choice. As an application, the paper examines the market's response to naked and underwritten calls of convertible bonds. The paper reports evidence that the market's response to calls of convertible bonds is correlated with the private information partially revealed by the firm's choice of call type. However, although the average treatment effect associated with an underwritten call is negative, it is not significantly different from zero. 相似文献

A general class of distortion operators for pricing contingent claims with applications to CAT bonds
Frédéric Godin Van Son Lai Denis-Alexandre Trottier 《Scandinavian actuarial journal》2013,2013(7):558-584
ABSTRACTThe current paper provides a general approach to construct distortion operators that can price financial and insurance risks. Our approach generalizes the (Wang 2000) transform and recovers multiple distortions proposed in the literature as particular cases. This approach enables designing distortions that are consistent with various pricing principles used in finance and insurance such as no-arbitrage models, equilibrium models and actuarial premium calculation principles. Such distortions allow for the incorporation of risk-aversion, distribution features (e.g. skewness and kurtosis) and other considerations that are relevant to price contingent claims. The pricing performance of multiple distortions obtained through our approach is assessed on CAT bonds data. The current paper is the first to provide evidence that jump-diffusion models are appropriate for CAT bonds pricing, and that natural disaster aversion impacts empirical prices. A simpler distortion based on a distribution mixture is finally proposed for CAT bonds pricing to facilitate the implementation. 相似文献

In this paper, we propose a new approach to household financial vulnerability analysis employing cluster technique in the identification of potentially vulnerable households. The cluster-based vulnerability indicator is applied to stress testing with the specific aim of assessing the extent to which the prolonged economic downturn following the Great Recession of 2008–9 hurt indebted households in Croatia. We compare the results based on the new approach with those based on traditional methods. Interest rate shocks have a stronger effect on household vulnerability in the traditional approach, whereas decrease in employment is found to be more disruptive in the cluster-based approach. 相似文献
