技术性贸易壁垒与合格评定程序

随着WTO和贸易自由化的发展，各国的关税水平大幅度降低，以及配额、许可证等非关税措施的逐步取消，大大促进了国际贸易的发展，技术贸易措施在国际贸易中的地位日益重要。合格评定程序是指任何直接或间接用以确定产品是否满足技术法规或标准要求的程序。合格评定程序是企业扩大对外出口、突破技术贸易壁垒的有效措施。     

Option Trading and the Intervalling Effect Bias in Beta

Prior studies show that the beta coefficient of a security changes systematically as the length of measurement interval is varied. This phenomenon, which is called the intervalling effect bias in beta, has been attributed to the friction in the trading system that causes the delays in the price-adjustment process. This study shows that option listing is associated with a decline in the beta intervalling effect bias. The decline is most pronounced for small firms. We also find that our sample firms grow significantly after option listing. Since prior research indicates that market value is a major determinant of the magnitude of the intervalling effect, we re-examine our results using a subsample that controls for market value. The results indicate that the decline in the beta bias from the pre-listing to post-listing period is still prevalent after we control for the change in firm size. Overall, the evidence is consistent with the notion that option trading reduces the delays in the price-adjustment process, which in turn reduces the intervalling effect bias in beta.     

Why are Small Firms Different? Managers’ Views

Do incentives differ between large and small organizations? Results from a representative survey of compensation managers are used to shed light on the issues. I find that (i) small establishments rely less on pecuniary incentives, and have a significantly more hostile attitude towards incentive schemes based on competition and relative rewards; (ii) large units are more vulnerable to mechanisms of efficiency wages, effects that remain even after controlling for differences in monitoring ability; (iii) large units are more prone to indicate that negative reciprocity is important, and that their employees care about relative pay. I argue that these findings fit with behavioral stories of incentives and motivation, in particular those stressing group interaction effects, inequity aversion and gift exchange.

湿地公园规划的生态服务功能影响预评价

鉴于湿地生态系统的特殊性和敏感性,科学地保护和利用湿地资源、合理地进行湿地利用规划,一直是相关学者所关注的问题;以安徽省北部淮河三汊河湿地为例,从水文调节、大气调节、水体净化、物质生产、文化功能、提供生境和生物多样性价值等方面采用替代成本法、恢复成本法、市场价格法和影子工程法对湿地生态服务价值进行经济核算;分别以生态服务功能价值的理论值(2152.9万元)和现状值(1982.7万元)为参考标准,进行湿地公园规划对湿地生态影响的比较分析,预评价湿地公园规划后的生态服务功能价值为2447.2万元,较理论值和现状值都高;在各项服务功能中,除物质生产功能影响为负值外,其它各项值均为正值,在水文调节、水体净化和文化功能方面变化值较大,因而,从生态服务功能角度考虑,可以认为公园规划具备合理性和可行性。

经济发展的税收效应定量分析

采取面板数据模型分析了经济发展的税收效应,发现经济发展的不同层面对税收的影响不同,表明政府在进行税收改革时要充分考虑经济发展的反作用。结果显示,生活水平提高总体上会降低税率、流转税比重和其他税比重以及提高所得税比重,实际经济增长率增加会提高税率和其他税比重、降低流转税比重和所得税比重,城乡收入差距扩大会降低税率、所得税比重和其他税比重以及提高流转税比重。
