我国无居民海岛使用权综合估价体系框架研究

随着海洋经济的快速发展,海洋空间资源开发利用的需求日益增加,海岛作为海洋经济中重要的空间资源要素备受关注。我国目前尚未建立系统的海岛空间资源价格评估体系,使得对无居民海岛估值认定缺乏规范性,进而影响估价的准确性。因此,为体现自然资源的市场价值,促进海岛使用权市场化交易进程,亟需建立无居民海岛空间资源估价制度,从评估管理、评估理论、评估技术三个层面构建我国无居民海岛空间资源估价体系框架,为无居民海岛使用权有偿出让提供支持和保障。

农村核心家庭的现代适应与权变

家庭作为个体的归属单位在现代生活中有其自身的适应逻辑。农村核心家庭在生命周期的各个阶段中,都呈现出灵动的家庭结构与代际互动模式以应对不同的境况,形成以第三代为中心联动母家庭的新的共同体形态。这种以倒置的亲子关系为主轴辐射大家庭的共同体实践,是市场化、国家行政力量和传统文化多重机制重塑的结果,更是尊重个体权利、权衡不同成员需求的家本位思想的现代延续。     

Air Pollution Materials Damage: Economics and the Law

Recent concerns about the adverse effects of acid rain have increased the attention given to materials damage effects from air pollution. This article surveys the economics of valuing materials damage effects and relates these methods to the technical aspects of estimating actual damages. The current statutory and regulatory framework within which materials damage effects are considered is also reviewed. The key weaknesses of the relevant sections of the Clean Air Act, in terms of effectively using economic and technical information on materials damage, are identified. The article concludes with several general observations concerning the regulation of materials damage effects.     

Implicit debt in public‐sector pension plans: An international comparison

Most countries have separate pension plans for public‐sector employees. The future fiscal burden of these plans can be substantial as the government usually is the largest employer, pension promises in the public sector tend to be relatively generous, and future payments have to be paid out directly from government revenues (pay‐as‐you‐go) or by funded plans (pension funds) which tend to be underfunded. The valuation and disclosure of these promises in some countries lacks transparency, which may hide potentially huge fiscal liabilities to be passed on to future generations of workers. In order to arrive at a fair comparison between countries regarding the fiscal burden of their public‐sector pension plans, this article recommends that unfunded pension liabilities should be measured and reported according to a standard approach for reasons of fiscal transparency and better policy‐making. From a sample of Member countries of the Organisation for Economic Co‐operation and Development, the size of the net unfunded liabilities as of the end of 2008 is estimated in fair value terms. This fiscal burden can also be interpreted as the implicit pension debt in fair value terms.     

由困难医学生问题谈思想政治工作队伍的建设

对105例困难医科大学生个案调查的详细资料表明,困难医学生的主要类型表现为:网络成瘾、经济困难、心理障碍、学习困难、人际关系紧张、以及具有上述两种或两种以上困难的综合问题类型。由于目前解决困难医学生的思想政治工作方法措施的效果有限,为实现单一的思想政治教育向涵盖政治信仰、思想素养、道德品质、文明行为、民主法制意识和健康心理的大德育的战略转变,必须加大投入,建立一支优秀的网络思想政治工作队伍,培养一支具有一定心理学专业知识和技能的思想政治工作者队伍。     

信息披露时间不确定与风险债务评估

本文研究当公司信息披露时间不确定、而信息披露时投资者能完全真实地了解公司价值的情形下风险债务的评估问题,假设关于公司真实价值的信息流服从泊松过程,得到了公司债务安全条款的阈值和公司债务价值评估的表达式。分析表明,当信息流到达率增大时,债务安全条款的阈值降低的同时导致债务价值的损失,但若公司价值增大,债务价值的损失将逐渐减小。

Will More Purchasing Options Benefit Customers?

This paper considers the sale of a seasonal product in the face of strategic customers. At the beginning of the selling season, the retailer announces both the price p_h at which the product will be sold during the selling season and the post‐season clearance price p<p_h for unsold items. We analyze two operating regimes: The “no reservation regime” allows a buyer either to purchase the product at price p_h when he arrives or to enter a lottery to purchase at price p if the product remains unsold. The “reservation regime” offers each buyer one extra option than the no reservation regime: reserve the product for purchase at the clearance price p. If the buyer reserves the product under the reservation regime and if it remains unsold at the end of the selling season, then he is obligated to purchase it at price p. We consider a situation in which heterogeneous customers with probabilistic valuation arrive in accord with a Poisson process. We characterize the rational purchasing behavior wherein each arriving customer is strategic; each customer takes other customers' purchasing behavior into consideration. By considering the Nash equilibrium of this game, we show that strategic customer behavior can render the customer to be worse off and the retailer to be better off under the reservation regime, despite the fact that this regime offers one extra option (reservation) to a customer. Hence, more purchasing options do not necessarily benefit customers.
