基于展望理论的投资组合保险均衡研究

投资组合保险交易策略是在保证一定财富水平的情况下,又不失去从有利市场中获利的机会。投资组合保险者将最低要保金额作为赢得或损失的参照点,这与展望理论所描述的决策行为是一致的。文章引入展望理论的价值函数建立一般均衡模型,模型推广了Basak的一般均衡模型,使其成为一个特例;同时,模型表明投资组合保险的存在将有效地降低市场波动率,进而降低风险溢价。     

“泛珠三角”少数民族聚居地区与发达地区的CPI波动性研究

本文中广西省和云南省被选取为"泛珠三角"少数民族聚居地的代表,广东省为"泛珠三角"发达地区的代表。利用3个省份的CPI数据,建立三元时变相关的广义自回归条件方差模型。通过分析3个省份CPI的波动性特征以及它们的时变相关系数,有助于研究"泛珠三角"经济带中的少数民族聚居地区与发达地区经济发展的波动性情况。

Municipal commonage policy and livestock owners: Findings from the Eastern Cape,South Africa

The new African National Congress government announced after 1994 that municipal commonage would be a pillar of their land reform programme. The Department of Land Affairs spearheaded this by acquiring new land to complement the existing ‘old’ commonages. The aim of old commonage was to supplement the income of poor urban residents through the subsistence user system whereas new commonage was intended as a ‘stepping stone’ for emergent farmers. We investigated the differences between old and new commonage farmers as well as how they perceived the Makana local municipality's capacity to manage the commonage. The results showed that local institutions were weak. Only 46% of the old commonage farmers were members of a local livestock association whereas 74% of the new commonage farmers were members. Most old commonage farmers (59%) were dissatisfied with local government's management of the commonage. In contrast, only 37% of the new commonage farmers were dissatisfied with the management of the commonage. There were no differences between old and new commonage farmers in terms of livestock owners’ characteristics and mean annual net direct-use value of livestock. There were also no differences in the age of the two types of commonage farmers. Furthermore, there was no association between the type of commonage and level of education. The mean annual net direct-use value of livestock on old commonage was R6308 compared with R9707 on new commonage. Although the income from livestock for new commonage farmers varied slightly from that of old commonage farmers, the annual productive output per farmer on old commonage was R473 ha⁻¹, three times higher than that of new commonage farmers which was R134 ha⁻¹. We suggest that new land policy legislation is needed in which poverty as well as the legal arrangements between all stakeholders is clearly defined. Furthermore, national departments need to be more involved with local municipalities to increase local management capacity.     

Chefs and suppliers: An exploratory look at supply chain issues in an upscale restaurant alliance

This paper examines some basic issues associated with supply chains in the context of acquiring local ingredients as part of producing a culinary tourism experience. Based on data collected from Executive Chefs at Relais & Châteaux restaurants through surveys and personal interviews, the authors document producer-to-chef relationships, why and how local ingredients are featured in menu listings, and how chefs communicate their use of local ingredients to their guests. The results also describe chefs’ beliefs about the use of local ingredients, as well as potential issues related to the use of suppliers and their perceptions of their guests’ expectations for their meals.     

Towards sustainable tourism planning in New Zealand: Monitoring local government planning under the Resource Management Act

In the light of the increasing pace and scale of tourism activity in New Zealand, the concept of sustainable tourism has become a key ingredient in the nation's tourism strategy. This paper explores sustainable tourism planning in New Zealand at the level of local government, and in particular, focuses on the implementation of the Resource Management Act 1991 (RMA) as a mechanism for achieving sustainable tourism. Using the findings of a survey of Regional Councils and Territorial Local Authorities, the paper explores public sector planning responses to tourism impacts and sustainability concerns in New Zealand. The paper extends the earlier work of Page and Thorn (1997. Towards sustainable tourism planning in New Zealand: public sector planning responses. Journal of Sustainable Tourism 5(1): 59-77; 2002. Towards sustainable tourism development and planning in New Zealand: the public sector response revisited. Journal of Sustainable Tourism 10(3): 222-238), which identified major issues of concern at local council level with regard to tourism impacts and argued the need for a national vision for tourism to ensure that the RMA achieved its original goals. Since then, a national tourism strategy has been published and changes in legislation have further empowered local authorities to further progress the sustainability agenda. This paper examines these developments and the ensuing implications, concluding that significant progress has been made in developing tourism policies at the local level, but that a number of constraints and issues limit the development of New Zealand as a sustainable destination.
