This article presents joint econometric analysis of interest rate risk, issuer‐specific risk (credit risk) and bond‐specific risk (liquidity risk) in a reduced‐form framework. We estimate issuer‐specific and bond‐specific risk from corporate bond data in the German market. We find that bond‐specific risk plays a crucial role in the pricing of corporate bonds. We observe substantial differences between different bonds with respect to the relative influence of issuer‐specific vs. bond‐specific spread on the level and the volatility of the total spread. Issuer‐specific risk exhibits strong autocorrelation and a strong impact of weekday effects, the level of the risk‐free term structure and the debt to value ratio. Moreover, we can observe some impact of the stock market volatility, the respective stock's return and the distance to default. For the bond‐specific risk we find strong autocorrelation, some impact of the stock market index, the stock market volatility, weekday effects and monthly effects as well as a very weak impact of the risk‐free term structure and the specific stock's return. Altogether, the determinants of the spread components vary strongly between different bonds/issuers.  相似文献

The lower-of-cost-or-market principle implies that assets may be sold above book value, by which hidden reserves are disclosed. To avoid taxation of these hidden reserves, in German-speaking countries companies are allowed to transfer them to a newly purchased asset within a fixed time period. In this paper, the optimal timing of hidden reserves transfers is developed with special attention to the term structure of interest rates and interest rate risk, and using the replicating principle known from the field of finance. The paper presents one model under certainty and, as a generalization of this model, another model under interest rate risk. In both models, the criterion used for decision-making is the value of the right to transfer, which can be interpreted as the initial cost of a replicating/hedging strategy for tax payments saved/incurred. In the model under certainty, the net present value concept is used to derive the value of the right to transfer. The procedure used in the model under interest rate risk is a combination of flexible planning and the no-arbitrage approach common in derivatives pricing. It is shown that the right to transfer hidden reserves with flexible timing is equivalent to an American-style exchange option. In addition, the impact of term-structure volatility on the value of the right to transfer is analyzed. The technique presented in this paper can also be used to solve other timing problems resulting from trade-offs between early and late tax payments/tax benefits.

This study develops the policy-making capabilities of the Ecological Footprint. The new capabilities we introduce in our Ecological Footprint model allow us to clarify policy options in the face of the increasing management complexity due to a more interconnected and uncertain world. We investigate the effectiveness of three illustrative policy options for reducing the Ecological Footprint of urban car transport: (1) improvements in efficiency/technology, (2) substitution with alternate fuel mixes, and (3) the reduction in demand by altering urban form. We investigate the success of policy options for a subnational case study jurisdiction in Australia, but in the uncertain global context. We use a resilience framework that considers critical social, economic, and environmental variables, multiple scales, and multiple possible futures. We find that delaying policy options to mitigate CO2 emissions from the transport sector will increase the risks borne by society as a result of future global uncertainty, the uncertain timing of globally coordinated action on climate change and the timing of peak oil. We also find that the success of local policy is affected by the global future which prevails. The use of the Ecological Footprint allows policy to be informed by the consequences of both CO2 emissions and increasing demand for land. The study provides a decision-making framework that allows local decision makers to make robust policy despite global uncertainty. This framework has wider applicability to other nations and/or subnational jurisdictions worldwide.  相似文献

The Personality Audit (PA) was developed to meet a need for a relatively simple multiple feedback instrument that could clarify the various motivational needs of executives. Using a psychodynamic approach to leadership, the PA allows the test-taker to assess him- or herself in seven personality dimensions important in human behaviour and to identify personal ‘blind spots’. The resulting insights can be used to formulate appropriate leadership development goals.

The objective of this paper is to describe the design and psychometric properties of the PA. This instrument, in contrast with other tools that can be used to clarify the inner theatre of individuals, is designed not only to report information given by the test-taker but also to reflect the perceptions of observers representing both the test-taker's public and private spheres. This paper describes in detail the conceptual foundations of the questionnaire, the psychometric methods used to confirm its validity and reliability, and possible directions for future research.  相似文献

As American society grows more diverse and the issues that must be decided grow more complex, the need for new forums and better forms for public debate increases. Is computer conferencing likely to meet this need because of its potential for facilitating public participation in government? To shed light on this question, we constructed, ran, and observed a computer conference on recombinant DNA among four participants with no previous experience in using computers and no scientific training. Results indicate that not only was this topic successfully discussed by lay people in this way, but that the conferencing mode of discussion was preferred by certain types of people. Our experience also gave us insights that may improve management of computer conferences for inexperienced users.  相似文献
