Does the Quality of Corporate Governance Affect Firm Valuation and Risk? Evidence from a Corporate Governance Scorecard in Hong Kong*

Using Hong Kong firm data, we construct an index of corporate governance during 2002–2005, which scores the corporate governance practices of listed companies from the public shareholders' perspective based on the Organization for Economic Corporation and Development Principles of Corporate Governance. The findings show that family firms and firms with concentrated ownership structures are associated with bad corporate governance. The evidence also shows that these firms improve their corporate governance practices slower than their peers. Overall, the quality of corporate governance is very significant in explaining future company stock returns and risk. Good corporate governance is associated with both higher stock returns and with lower risk. Improvements in corporate governance are associated with significantly higher stock returns and lower company risk.

国际碳市场与能源市场动态相依关系研究与启示——基于DCC-MVGARCH模型

本文应用基于条件多元t分布的DCC-MVGARCH模型研究CERs期货价格收益同能源期货价格收益之间的动态相依关系,旨在探讨跨品种套期保值的可行性及操作策略,为国内减排企业及时对冲CERs价格波动风险提供经验依据。实证结果显示:CERs期货价格收益和能源期货价格收益之间存在正相关性;相较Euro天然气期货合约与GlobalCoaL期货合约,BRenT原油期货合约更适用于构造套期保值组合;以动态条件相关系数测算时变套期保值比率明显降低了组合收益的方差并提升了组合收益的均值,其套期保值绩效要优于条件相关系数。基于此结果本文认为,国内减排企业应当积极采取相关套期保值策略并定期更新动态条件相关系数均值,政府主管部门亦应着手实施碳资源战略储备以对冲风险。     

Demographic change,human capital accumulation and R&D‐based growth

Employing an overlapping generations model of R&D‐based growth with endogenous fertility and education decisions, we examine how demographic changes induced by an increase in life expectancy influence the long‐run growth rate of the economy. We demonstrate that life expectancy, when relatively low (high), positively (negatively) affects economic growth. This paper also compares the growth implications of child education subsidy policies (i.e., policies for enhancing basic education) and child rearing subsidy policies (i.e., pro‐natal policies) and demonstrate that while the child education subsidies consistently foster economic growth, child rearing subsidies may negatively affect economic growth.     

绥芬河市新华街隧道围岩稳定分析

绥芬河市新华街隧道是目前黑龙江省最长的公路隧道,该隧道东起新华街,西至301国道,其最大埋深为101.1m,由于隧道穿越区域地质条件复杂,地应力较高,因此在前期施工过程中,已经出现了局部掉块现象。为了避免隧道在施工与运营期内出现大面积垮塌情况,本文对隧道的稳定性进行了分析评价,该隧道出现岩爆的可能极小,但是洞室围岩有塑性破坏的可能,为了防止由于塑性破坏诱发的塌落现象,建议采用4~5m的系统锚杆进行支护。

Tracking Can Be More Equitable Than Mixing

Parents and policy‐makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity. I answer this question by analyzing the influence of peers on future educational results. I define an equal opportunity policy as one that maximizes the average lifetime income of the worst‐off type of individuals in society (i.e., students from disadvantaged backgrounds). I find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high.     

情感乡村模式与璧山县乡村旅游实践研究

＂快乐经济＂、＂幸福经济＂等可统称为＂情感经济＂,它为我们提供了＂可触摸＂情感的思维。在对情感经济回顾和＂情感乡村＂概念界定基础上,认为情感经济可用于乡村旅游实践。在璧山县＂情感乡村＂旅游发展实践中,通过挖掘＂情感乡村＂旅游元素、分析＂情感乡村＂旅游市场,提出快乐乡村、幸福乡村、浪漫乡村以及和谐乡村的乡村旅游项目设计理念,得出＂情感旅游＂是乡村旅游发展重要方向的结论。
