Assessing Voluntary Programs to Improve Environmental Quality

The last decade has seen a dramatic increase in the use of voluntaryapproaches (VAs) to environmental protection, which has spurned agrowing literature on the relative merits of voluntary vs. mandatoryapproaches. This paper draws on that literature to discuss both thetheoretical and empirical issues that arise in the evaluation orassessment of a particular VA. We consider both the environmentaleffectiveness and the efficiency of this policy approach. Our aim is toaid policymakers in evaluating a specific program or in thinking aboutthe use and design of a VA. We identify some key features that arelikely to increase both the effectiveness and the efficiency of VAs.

Regulation and investment behaviour in the telecommunications sector: policies and patterns in US and Europe

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings.

Managing and financing metropolitan public services in China: experience of the Pearl River Delta region

Under China’s current fiscal policies and inter-governmental relations, it is a significant challenge to finance and deliver public services across jurisdictions. This challenge was met in the Pearl River Delta region in southern China with a collaborative governance approach. Directives from higher-level governments and horizontal inter-city fiscal arrangements were successfully combined to deliver public services. Effective networks should be developed to improve co-ordination and collaboration in delivering cross-jurisdictional public services.     

中国出境旅游"双高"格局与政策取向辨析——兼与戴学锋、巫宁同志商榷

中国出境旅游的高增长和高消费现象引发了对出境旅游不经济性的讨论.本文通过与"中国出境旅游高速增长的负面影响探析"一文作者的商榷,认为出境旅游的迅速发展是我国现阶段宏观经济发展的必然结果,属于"补涨"性质;出境旅游消费存在"虚高"现象;出境旅游的发展为我国旅游业跨国经营创造了有利条件,而跨国经营是克服出境旅游不经济性的最佳途径.     

事务所规模与年报会计政策“类准则”披露——基于文本分析的经验证据

通过计算上市公司年报会计政策披露的“类准则”程度,讨论会计师事务所规模是否为影响上市公司会计政策披露行为的重要因素。研究发现：（1）由规模较大的会计师事务所审计的上市公司,年报会计政策披露的“类准则”程度较低,会提供更多公司会计政策的个性化信息。（2）在上市公司风险增强和会计准则重大变化的两大类场景中,事务所规模与年报会计政策披露“类准则”程度之间的关系都得到增强,说明事务所的风险压力和事务所能力是重要的机制路径。（3）由同一事务所审计的上市公司会计政策披露的“类准则”程度更一致,具有同所效应。（4）基于会计师事务所变更的检验发现,若变更后的事务所规模更大,则会计政策披露的“类准则”程度会降低;若变更后的事务所规模更小,则会计政策披露的“类准则”程度会提高。
