A fundamental question in the study of mortality‐linked securities is how to place a value on them. This is still an open question, partly because there is a lack of liquidly traded longevity indexes or securities from which we can infer the market price of risk. This article develops a framework for pricing mortality‐linked securities on the basis of canonical valuation. This framework is largely nonparametric, helping us avoid parameter and model risk, which may be significant in other pricing methods. The framework is then applied to a mortality‐linked security, and the results are compared against those derived from other methods. 相似文献

The neoliberal consensus is that state funded pensions are not sustainable in the long term, due to declining fertility and longevity. In response, policymakers have pointed to the advantages of privately funded pension systems. This article compares the social provisioning of these two systems using the circular flow of income as an organizing framework. A series of pitfalls in the private model are examined, including inequality of provision, mis-selling of investment products, and punitive charges. 相似文献

This work compares the effects of neoliberal and post-neoliberal land-use policies on forest cover along the Corredor Bioceánico of southeastern Bolivia to determine if rates of agriculturally driven forest clearance have changed since the Morales’ administration came to office in 2005. Satellite image analysis, supported by semi-structured interviews with farmers and representatives of key institutions, shows that deforestation for commercial agriculture in Santa Cruz continues and has increased in certain “hotspots”. Previous research has shown that the environmental effects of neoliberalism on forest cover are varied, but more broadly, reduced state intervention has meant less environmental regulation and greater deforestation, while strong government is better able to curtail deforestation. Although neoliberal policies triggered an unprecedented level of forest clearing in Bolivia, rates have generally continued to increase and can be indirectly linked to the administration's new agrarian reform and pro-environmental regulations. This trend is counterintuitive and stems from unanticipated responses such as deforestation through fire to prove productive use under the reform's socio-economic function requirements. Given increased regulation and enforcement of forest clearing and burning under Morales, in contrast to the neoliberal era, our analyses suggest that rates will continue to increase under the current political climate, which has further polarized the opposition in Santa Cruz. 相似文献

The Boscombe Artificial Surf Reef (ASR) is the first ASR in Europe and is the flagship project of an ambitious scheme to regenerate Boscombe Spa, a resort-suburb of Bournemouth, UK. The Boscombe ASR therefore presents a unique coastal management challenge in Europe for which there is no precedent and little pre-existing management capacity. Through a multi-stage research process, this paper identifies the likely governance challenges that will face the Boscombe ASR. These were found to include overcrowding, a lack of surf skill and etiquette amongst visitors, conflict between different uses, and localism. Through a consideration of approaches to surf governance elsewhere, suggestions are identified for management interventions that may work in Boscombe. The paper concludes by identifying underlying tensions between the need to attract visitors to support the regeneration of Boscombe, the surf safety issues created by an influx of novice surfers, and the potential for the breakdown of the norms governing the self-regulation of surfing. 相似文献

Determinants of Attendance in the Quebec Major Junior Hockey League: Role of Winning,Scoring, and Fighting 总被引:1,自引:0,他引:1
Attendance in the Quebec Major Junior Hockey League was studied for the 2009 to 2010 season. This junior league, part of the
Canadian Hockey League system, serves as a development league for teenage players who attempt to parlay their participation
in this league into a professional career. Fan demand for this level of hockey is found to be sensitive to the success of
the home team and to exhibit normal consumer responses to weekday and monthly effects with weekends being more popular and
attendance increasing throughout the season toward the playoffs. On-ice factors such as scoring, a proxy for excitement, and
fighting are not shown to have a significant effect on attendance. 相似文献

The economic impacts of policies to reduce water pollution from agriculture have been explored in a number of studies. A standard assumption in this literature is that farm income support policies are given. However, the modern public choice view of agricultural policy suggests that significant environmental initiatives in agriculture would likely be accompanied by changes in farm income policies to protect those with a significant stake in agriculture. We explore the potential effects of such compensating adjustments on the costs and effectiveness of taxes on polluting chemical inputs in US corn production. We find that compensating farm policy adjustments can greatly increase the costs and reduce the effectiveness of the environmental protection measure. The results also indicate the potentially high costs of poor policy co-ordination. 相似文献

This paper explores the relationship between the Keynesian multiplier and Pasinetti's model of pure production. Key assumptions of Pasinetti's model are its multisectoral structure, the definition of all income as a reward to labouring activities and, as a consequence, the operation of a pure labour theory of value. A translation between these models is effected by introducing investment as an exogenous determinant. By drawing from Keynes to apply his concept of the wage unit, it is possible to aggregate from Pasinetti's multisectoral model to a genuinely macroeconomic multiplier. This provides a way of using the scalar Keynesian multiplier without making the restrictive one-commodity assumption. In addition, this formal demonstration enhances our understanding of the relationship between the wage unit and the labour theory of value. Finally, critics have argued that Pasinetti downgrades the importance of institutional analysis; in contrast, the derivation of a scalar Keynesian multiplier contributes to an understanding of how relevant Pasinetti's approach is to the analysis of a monetary production economy. 相似文献

We investigate conflicts between wildlife conservation and recreational use that can occur at open-access sites when visitors dislike crowding. A theoretical model is proposed which determines the spatial distributions of visitors to a beach, given their willingness to walk to avoid crowding and the configuration of beach access points. This model is estimated for three sections of coastline in eastern England using data from aerial video photography. Visitor density is strongly and negatively correlated with distance from access points. Willingness to walk has a highly skewed population distribution. We discuss the implications of these findings for the management of conflicts between conservation and recreation at open-access sites. 相似文献
