Effectiveness and Effects of China’s Capital Controls

I. IntroductionNations at every stage of development and in every region of the world are more closelylinked through trade in goods and services, through flows of funds and investments ineach others’ economies than ever before. But in sharp contrast to more and more nationsloosening restrictions on international trade, controls over capital flows are still substantialnearly everywhere except in the most developed economies. This is certainly the case inChina, where restrictions on movements …     

A note on forecasting international tourism demand in Spain

This paper considers the extent to which price and income proxy variables help in forecasting tourist demand in Spain. Contrary to some recent studies, we found that the inputs' contribution in terms of fitting and forecasting is nil when compared with alternative univariate models. Whether these findings are the results of the restrictions embedded in building the proxy inputs or in a poor specification of the dynamics of these models remains to be seen. We also contend that when dealing with medium, long-term forecasting comparisons, the use of the traditional aggregate accuracy measures like RMSE and MAPE help very little in discriminating among competing models. In these situations, predicted annual growth rates may be a better alternative.

保障措施争端中的焦点问题及其启示

WTO的《保障措施协定》提供了对成员方内部产业安全的保护手段,也因此引起了保障措施争端。保障措施争端中的焦点集中在事实性争议和程序性争议两方面,争议的两个方面都是值得我们注意的。     

石油企业机关量化管理的思路和对策

石油企业机关管理效率和服务质量不高的原因是管理中缺乏量化的约束和激励机制,要改变这种“大锅饭”现象,必须做到目标量化、责任量化、考核量化的“三量化”管理。     

Valuing Food Store Access: Policy Implications for the Food Stamp Program

Food stamp recipients may lack access to larger stores, reducing the availability of nutritious food. Reliance on smaller stores may have undesirable impacts. Policy alternatives include limiting food stamp redemption to larger stores and subsidizing store development. I estimate that limiting redemption to supermarkets and grocery stores, or supermarkets alone, results in losses ranging from $499.2 million to $1.05 billion, or $1.17 billion to $2.44 billion (respectively) annual loss in food stamp recipient welfare nationwide. The impact of improving access is also significant, ranging from $333.6 million to $931.2 million.     

美国钢铁贸易保护争端及其对世界经济贸易的影响

美国钢铁保障措施的出台是经济衰退期外贸政策保护主义倾向进一步加强的具体表现。作为WTO成员，美国按国内法201条款实施的钢铁保障措施必须符合WTO保障措施规则。但美国钢铁保障措施即使符合WTO规则，也是通过损害其钢铁贸易伙伴正当利益来追求本国利益最大化。因此，在全球贸易体制约束下，美国的行为必然引起各相关方与美国之间运用全球贸易规则的利益博弈，并由此对世界经济贸易产生重大影响。

Sample Design and Allocation for Random Digit Dialling

Sample design and sample allocation methods are developed for random digit dialling in household telephone surveys. The proposed method is based on a two-way stratification of telephone numbers. A weighted probability proportional to size sample allocation technique is used, with auxiliary variables about the telephone coverage rates, within local telephone exchanges of each substrata. This makes the sampling design nearly “self-weighting” in residential numbers when the prior information is well assigned. A computer program generates random numbers for the local areas within the existing phone capacities. A simulation study has shown greater sample allocation gain by the weighted probabilities proportional to size measures over other sample allocation methods. The amount of dialling required to obtain the sample is less than for proportional allocation. A decrease is also observed on the gain in sample allocation for some methods through the increasing sample sizes.
