The Effects of Public Ownership and Regulatory Independence on Regulatory Outcomes

We examine the effects of public ownership and regulatory agency independence on regulatory outcomes in EU telecommunications. Specifically, we study regulated interconnect rates paid by entrants to incumbents. We find that public ownership of the incumbent positively affects these interconnect rates, and suggest that governments influence regulatory outcomes in favor of incumbents in which they are substantially invested. However, we also find that the presence of institutional features enhancing regulatory independence from the government mitigates this effect. In order to study regulatory independence, we introduce a new cross-country time-series database—the European Union Regulatory Institutions (EURI) Database. This database describes the development of institutions bearing on regulatory independence and quality in telecommunications in the 15 founding EU member states from 1997 to 2003 *We thank Laurent Pipitone for superb research assistance.

论GIS在社会经济领域中的运用

地理信息系统是一种新兴的技术工具,它不仅被应用在现代测绘、军事国防、野外数据采集等自然科学方面,而且被广泛应用在社会经济领域中,在管理和决策中具有重要的作用.随着人类获取空间数据能力的不断提高和信息技术的发展,地理信息系统的应用将提升到一个新的深度和广度,它将在国民经济信息化中发挥重要的作用.本文介绍地理信息系统的基本概念及其在经济、管理、法律等领域中的应用实例,着重强调在社会经济领域中开展地理信息系统应用研究的意义.     

Regulatory and environmental effects on public transit efficiency: a mixed DEA-SFA approach

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O. Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies, the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public transit networks.      

湖南八大公山国家级自然保护区国家重点保护和珍稀濒危植物区系分析

从属和种的水平上分析了八大公山国家级自然保护区国家重点保护和珍稀濒危植物的区系成分特点。结果表明,该保护区共有国家重点保护和珍稀濒危植物31科44属53种。其中有国务院1999年8月4日批准公布的I级重点保护植物4科4属6种,II级重点保护植物18科23属29种;有《中国珍稀濒危保护植物名录》(1987)和《中国植物红皮书》所列的濒危植物2科2属2种,稀有植物14科15属16种,渐危植物15科19属20种。其区系具有由亚热带植物区系向温带植物区系过渡,但热带性质比较明显的特点,而且中国特有成份是该区系中非常重要的组成部分。

Mean-variance hedging for interest rate models¶with stochastic volatility

The mean-variance hedging approach for pricing and hedging claims in incomplete markets was originally introduced for risky assets. The aim of this paper is to apply this approach to interest rate models in the presence of stochastic volatility, seen as a consequence of incomplete information. We fix a finite number of bonds such that the volatility matrix is invertible and provide an explicit formula for the density of the variance-optimal measure which is independent of the chosen times of maturity. Finally, we compute the mean-variance hedging strategy for a caplet and compare it with the optimal stategy according to the local risk minimizing approach.

On the cost-benefit of the regionalisation of the National Health Service

In this paper we analyse in formal terms the desirability of the regionalisation of a National Health Service. The policy consists of a devolution process, i.e. the increase in the health services provision to be decided by a region and financed by an increase in its revenues. The change is a marginal one, as it regards the part of supply of the health services exceeding a minimum standard, which for purposes of equity is maintained uniform in the national territory. As the central government is responsible for this component of the provision of health care (a federal “mandate”), the level of the said component is chosen by this authority and financed by federal taxation. Moreover, the government also applies an equalisation scheme based on the difference between a standard level of tax revenues and the revenues which the region is deemed able to raise for this purpose. Within the theoretical context of welfare improving reforms with distortionary taxation, we derive two conditions which focus on the regional, as well as the social, convenience of regionalisation.
