应对美国对华贸易保护政策的路径选择

文章指出,金融危机以来,伴随着全球贸易的急剧萎缩,贸易保护主义也风起云涌,特别是美国等一些西方国家近期针对中国的贸易保护措施更是纷纷出台,对我国经济发展造成了不利影响,成为我国经济发展的一个制约因素。文章认为,面对日益严重的贸易保护主义,政府、企业应采取积极的应对措施,建立健全贸易救济系统、充分利用WTO争端解决机制、实现对外贸易保护前置化和鼓励创立自主品牌等,以突破美国对华贸易保护的藩篱。

A comparison of work absence periods and the associated costs for two different modes of exercise therapies for patients with longstanding subacromial pain

Abstract

Background: There are no studies on economic issues concerning rehabilitation exercises for shoulder pain.

Objective: The aim of the study was to investigate sick leave and the associated costs after a medical exercise therapy programme in patients with longstanding subacromial pain/impingement.

Methods: A randomised controlled trial in which 61 patients were randomly assigned either to a high-dosage medical exercise therapy group (HD) (n=31) or to a low dosage exercise therapy group (LD) (n=30). Both groups were given three treatments a week over 3 months. The differences between the groups were number of repetitions, number of sets and time performing global aerobic exercises.

Results: The outcome for the HD group was significantly (p<0.05) better compared to the LD group. The reduction in costs for sick leave for the HD group was 59.1%, whereas for the LD group, the reduction was only 42.3%, which is a significant difference.

Conclusion: In patients with longstanding subacromial pain, HD medical exercise therapy might be an efficient treatment approach.

Aid Effectiveness,Debt Relief and Public Finance Response: Evidence from a Panel of HIPC Countries

Substantial amounts of debt relief have been granted to a set of low-income countries, as an alternative aid modality. Although the theoretical case for debt relief is firmly established, only empirical analysis can show whether debt relief is indeed a (more) effective mode of aid delivery. We investigate the linkages between debt relief and other fiscal variables such as current expenditure, government investment, taxation and domestic borrowing, in comparison to the effects of grants and concessional loans. We find that the fiscal impact of HIPC debt relief follows fairly complex dynamics. For example, debt relief initially reduces government investment, but the effect becomes positive after two years, well outperforming other modes of aid delivery. JEL no. F34, F35, O11, O19     

我国增值税地方分享部分的区域间分配办法及其改进

1994年分税制财政管理体制改革以来，我国增值税地方分享比例出现了不断下降的趋势。与其他开征增值税、并实行增值税中央与地方分享的OECD国家相比，目前我国地方政府的增值税分享比例并不高。但是，增值税地方分享部分按来源地在各地区间分配的操作办法仍然难以平押地方政府的投资冲动，不利于促进区域间基本公共服务的均等化，也不利于改进政府的执政理念。在仍将增值税地方政府分享部分明确为地方收入的基础上，应改革按来源地在各地区间分配的办法，建立一种综合考虑各相关因素的更为合理的分配策略。     

Dual sourcing of a newsvendor with exponential utility of profit

Dual sourcing strategies supplement inflexible, low-cost country sourcing with quick response manufacturing. Due to short product life cycles, combined with uncertain demand, dual sourcing strategies are very common in several industries, in particular in the sporting goods or fashion industries.Even though scholars have given some attention to the analysis of dual sourcing strategies, the importance of the decision-maker’s risk preferences has not been covered yet.In this paper we analyse dual sourcing strategies using an extended single-product newsvendor model with two order points. Different risk preferences will be modelled using an exponential utility function. Within realistic parameter ranges, the optimal order quantities can only be numerically computed. The findings of this paper show that dual sourcing strategies are always preferable to an exclusive offshore approach, as long as the onshore ordering costs are smaller than the selling price of the considered product. The more risk-averse the decision-maker, the smaller the offshore order quantity will be.
