Estimating the benefits of farm animal welfare legislation using the contingent valuation method 总被引:2,自引:0,他引:2
This paper presents the method and findings of a contingent valuation (CV) study that aimed to elicit United Kingdom citizens' willingness to pay to support legislation to phase out the use of battery cages for egg production in the European Union (EU). The method takes account of various biases associated with the CV technique, including ‘warm glow’, ‘part‐whole’ and sample response biases. Estimated mean willingness to pay to support the legislation is used to estimate the annual benefit of the legislation to UK citizens. This is compared with the estimated annual costs of the legislation over a 12‐year period, which allows for readjustment by the UK egg industry. The analysis shows that the estimated benefits of the legislation outweigh the costs. The study demonstrates that CV is a potentially useful technique for assessing the likely benefits associated with proposed legislation. However, estimates of CV studies must be treated with caution. It is important that they are derived from carefully designed surveys and that the willingness to pay estimation method allows for various biases. 相似文献

Longevity Risk 总被引:1,自引:0,他引:1
Most of the western world has seen a steady increase in the average lifetime of its inhabitants over the past century. Although
the past trends suggest that further changes in mortality rates are to be expected, considerable uncertainty exists regarding
the future development of mortality. This type of uncertainty is referred to as longevity risk. This paper reviews the current
state of the literature concerning longevity risk. First, we discuss the modeling of future mortality, including the Lee and
Carter (J Am Stat Assoc 87:659–671, 1992)-approach, as well as other approaches. Second we discuss the importance of longevity
risk for the solvency of portfolios of pension and life insurance products. Finally, we investigate possibilities for longevity
risk management. In particular, we consider longevity risk management through securitization and/or pension and insurance
(re)design. 相似文献

In deciding to keep or fell a forest stand given its age, the risk of loss of timber through wildfire is an important consideration. If trees also have value from sequestration of carbon, another effect of fire is the unplanned loss of stored carbon. Factors affecting the decision to keep or fell trees, and how much to spend on fire protection, are investigated using stochastic dynamic programming, using carbon sequestration in stands of mountain ash in Victoria as a case study. The effect of treating sawlogs as a permanent carbon sink after harvesting is explored. 相似文献

This paper presents explicit solutions for expanding monocentric cities with two or more income groups. Housing is durable but deteriorates over time, and redevelopment cannot take place. Landlords have perfect foresight. The utility function and housing technology are Cobb-Douglas. Population, per capita income, and transportation costs per mile change at constant percentage rates. The model is solved analytically, using an infinite time horizon. As development proceeds outward, a constant fraction of land is developed with high-income housing, and the remaining land is reserved for future low-income development. At any time, housing is constructed at one distance for high-income consumers, and at a lesser distance for low-income consumers. High-income housing is first occupied by high-income consumers, then filters to low-income consumers, and is ultimately abandoned. Low-income housing is first occupied by low-income households, and ultimately abandoned. 相似文献

There has been rapid development in the methods, data and protocols for the assessment of product sustainability over the past decade. Notwithstanding this welcome development, the widespread provision of sustainable products has not occurred. Moreover, indications from a myriad of surveys suggest that consumers remain full of intent to purchase sustainably, yet these stated preferences have not translated into a widespread uptake in the purchase of more sustainable products. Heightened interest in climate change over the past couple of years has led to rising calls for labelling to allow consumers to differentiate between more or less sustainable options. Such calls apparently assume that if consumers are presented with appropriate label information their purchases will change and more sustainable purchasing will result. For many observers these calls bring more than a ring of déjà vu as the failures (or at least unfulfilled expectations) of environmental labelling schemes of the past spring to mind. A review and assessment of eco‐labelling schemes is presented. Discussion focuses on the history, successes and failures of such schemes, and consideration of their potential role (or not) in future shifts towards sustainable consumption. Behavioural, social practice, institutional and infrastructure factors are considered and labelling, legislation and other options are explored. Conclusions are drawn regarding potential routes to sustainable consumption, with particular reference to eco‐labels. 相似文献

We test the signaling and wealth transfer hypotheses around the announcement of share repurchases using a recent and larger sample of data than previously examined while employing a methodology designed to enhance the power of our tests. Disentangling the wealth transfer and signaling hypotheses is difficult; they are not mutually exclusive and can have opposite effects for bondholders. Wealth transfers decrease bondholder wealth while positive signals increase it; the combined result obscures tests of each hypothesis. By focusing on sub-samples where signaling is more and less likely to be present we increase our ability to isolate the separate effects. In addition to traditional tests of wealth effects, we feature information inherent in the correlation of wealth changes to equity and debt. Our results are generally consistent with the positive signaling effect of stock repurchases, but also provide some support for wealth transfer. Our work also emphasizes the importance of trying to disentangle the various hypotheses. In the subset of option funding repurchases, where signaling effects are less likely, the positive correlation of wealth changes between stockholders and bondholders is completely eliminated. Bond ratings are much more likely to be upgraded in samples without executive options which is precisely where the signaling effects are expected to be concentrated. Firms with weaker shareholder rights experience greater bondholder wealth losses at the announcement of stock repurchases. 相似文献

This study develops a composite model and a two-dimensional classification illustrating the seeds of organisational decline. In the first dimension, the origins of decline are shown as being internal or external to the organisation. The second dimension links the nature of the decline problem to people, technology, or fiscal policy factors. A Delphi study lent preliminary support to the conceptual model and suggested certain amendments. The revised model was then tested using a sample of 44 public accountants. The results suggest that accountants use information about an organisation's people, technology, and fiscal policies when assessing its likelihood of declining, and that human resources is the most powerful of the three factors. 相似文献

This research attempts to discriminate empirically between the predictable events and resolution irrelevancy hypotheses as both pertain to abnormal stock price performance around regular and special proxy statement mailing dates and the related shareholder meeting dates. We find no evidence that these events result in the positive wealth effects suggested by the predictable events hypothesis. We do find evidence of increased idiosyncratic stock price volatility or information flow around special meeting proxy statement mailing dates and special meeting dates. Thus, our evidence supports the resolution irrelevancy hypothesis. 相似文献
