Statistics for Studies of Human Welfare

Developments in the recent past have substantially increased our ability to measure, compute, and communicate. We take the view that a corresponding improved understanding of processes in the life sciences will come about only through more intensive studies of properties of statistical methods and algorithms and transparent, open source computing environments.     

The liquidity effects of foreign exchange intervention

This paper examines the effectiveness of foreign exchange intervention in a two-country, two-currency, general equilibrium model that allows for liquidity effects. Both sterilized and non-sterilized intervention operations have significant impacts on the allocation of liquidity in international financial markets. Whether intervention is successful in moving the exchange rate in the desirable direction depends upon the degree of sterilization of intervention and the intratemporal elasticity of substitution of the consumption goods. The model shows that there exist circumstances in which the response of exchange rate to intervention is ‘perverse’ as documented in the empirical literature.     

干预行为——经济法中的“法律行为”

在我国法学界,"法律行为"有两种不同含义,一是民法上的含义,意指意思效果行为。这也是法律行为的原初含义。另一是法理学上的含义,意指具有法律效果的行为。经济法的法律行为应采何意?从相关的论述看,多是在法理学意义上使用的。笔者之见,法律行为应回归其原初含义,而最能反映经济法特征的法律行为就是"干预行为",即公共经济组织的"公意"表示及执行行为,包括宏观调控和市场规制行为。     

政府干预与我国会展业的发展

Chernobyl Effects on Domestic and Inbound Tourism in Sweden -- A Time Series Analysis

This paper estimates the impact of the Chernobyl nuclear accident on domestic and international tourism in Sweden. From ARIMA time series forecasts, outlier search, and intervention analysis based on regional monthly accommodation data from 1978–1989, no effect on domestic tourism is found. However, there is an enduring deterrence effect on incoming tourism. The loss of gross revenue from incoming tourism because of the Chernobyl accident, is estimated to 2.5 billion SEK.     

论就业机会产品失灵问题的政府治理

中国劳动力市场的典型特征是就业机会与劳动力资源之间的信息分布不对称，而就业机会实质上是一种公共产品。根据市场失灵理论，解决公共品市场失灵问题时政府与市场两条思路均可采用。文章沿袭自古典经济学家庇古以来的传统，认为应该引入政府的干预来解决就业机会的市场失灵问题．并在此基础上提出相应的建议。     

Do central banks lose on foreign-exchange intervention? A review article

Estimates of central bank intervention losses or profits vary widely; some estimates find substantial losses, others profits. In most cases, estimated profits are not risk-adjusted, and risk adjustment can have large effects. Furthermore, profit estimates involve variables integrated of order one, and because of this test-statistics may have nonstandard distributions; few studies take this into account. Estimates of risk-adjusted profits for the US Fed and the Swedish Riksbank, with allowances for possible nonstandard distributions, suggest that neither made losses and might have made significant profits.     

政府主导还是市场主导--我国转轨金融运行机制的评价研究

转轨过程中,我国金融运行机制是采取政府主导还是市场主导模式是经济学界争论的焦点,文章应用ARCH类模型对我国金融运行机制进行实证研究,结果表明我国金融运行机制与西方市场经济国家存在显著区别。在我国转轨的特定阶段,金融系统无法依靠自身的力量达到稳定状态,只有靠外部力量的非市场干预才能实现金融系统的平稳运行。目前在金融系统自身不具备自我稳定的功能条件下,政府的外部干预是金融系统平稳运行的前提,否则会导致金融系统陷入剧烈的波动之中。     

财政补贴的竞争法审查及其改进——兼论《公平竞争审查制度实施细则（暂行）》

财政补贴是国家干预经济的重要手段,能够促进产业结构调整和转型升级、平衡和加速地区间的经济发展,但极易对市场公平竞争带来消极影响,例如破坏市场结构、误导市场行为、减损市场绩效,等等。《公平竞争审查制度实施细则（暂行）》对此予以重点关注,但缺乏全面性的制度构建。这方面,欧盟国家援助制度值得我们学习和借鉴。欲改进我国财政补贴的竞争法审查,必须落实公平竞争审查制度,坚持必要性原则、公平原则和透明度原则,同时要建立补贴评估机制、豁免机制、信息披露机制和异议机制,以规范财政补贴的实施,平衡财政补贴和竞争政策的冲突,确保市场竞争机制不被财政补贴所扭曲。
