人民币国际化背景下汇率对工业行业就业的影响——基于跨境贸易结算的影响因素视角

将跨境贸易人民币结算比重引入劳动力市场动态均衡模型,推导出汇率影响就业的全新路径,并利用2000-2018年中国工业行业面板数据进行实证分析。研究发现:通过进出口产品结构贸易路径,汇率对行业总体就业的正向影响最显著,其次是经由汇率变动预期路径,而汇率通过净出口指数路径对就业的负向影响较微弱。人民币汇率对不同行业就业的影响产生差异的根源是不同行业进出口产品结构及产品异质性的差距导致在汇率变动的不同情形下,行业间跨境贸易人民币结算的水平不同,从而造成外贸企业对劳动力的需求具有差异。并且,技术特征及贸易来源地特征是造成行业间就业水平差异的显著因素。     

Assessing the Performance of the Price Cap Plan for Local Exchange Carriers in the United States

In 1991 the FCC implemented a price cap plan for local exchange carriers' interstate access service designed to deal with the regulatory boundaries problem arising from the breakup of AT&T in 1984. The experience with the price cap plan demonstrates the difficulty of predicting productivity growth accurately and makes clear that regulators cannot depend upon a pure price cap plan to keep prices within a reasonable range of costs. With periodic reviews to readjust plan parameters, however, a price cap plan can maintain the rate-of-return close to the target rate-of-return without diminishing the price cap plan's incentives for efficient production. A simple method of recalculating the X-factor based on the rate-of-return over the previous three years worked well in simulations. If this procedure had been used over the price cap period 1991 to 2000, prices would have been 20 percent lower and expenditures on LECs' telecommunications service subject to a price cap would have been $3.8 billion lower.     

加速折旧方法的理论分析

加速折旧方法计算模型建立的基本理论依据是:从模糊概念出发,根据平均年限法计算年折旧额的基本计算公式结构,同时结合加速折旧的要求,将定性与定量分析结合在一起,从而建立的一种计算模型。     

国际法框架下的人民币汇率制度选择

近年来,人民币汇率及汇率制度选择问题成为国际经济中的持续热点问题之一。随着入世过渡期的结束,中国经济已经日益融入世界经济体系,人民币汇率及汇率制度问题已经成为中国经济发展中必须长期面对的常态性问题。对于这个问题的研究,不应仅限于以往研究中的币值低估与否,是否违反相关国际公约等方面的单一研究模式,而需要在相关国际法框架下,从经济、政治及国际法等多角度加以综合研究,以制定相应的长期应对策略,并在此基础上通过对国内法上相关制度的完善保证中国经济的长期平稳发展。     

Crime,detection rate,and the police: A macro approach

Dutch criminality and its relation to the performance of police and justice have only recently been analyzed at the macro level (e.g., at the level of municipalities or the whole country). This type of approach is a useful supplement to analyses at the micro level (that of individuals), which are more common in Dutch empirical criminological research. The main results of such a macro approach are presented in this article. We conclude that the per capita numbers of youth, divorced people, and unemployed contribute significantly to the crime rate. The police strength and solving rates are important factors as well. Analysis of the production process of the police reveals that detecting one more case of driving under the influence is far more expensive than solving one more other crime or handling one more traffic accident. The results are combined to sketch a cost-benefit approach of different strategies in allocating more resources to the police. Allocating extra resources to solving more cases of vandalism gives the best cost-benefit ratio.

新加四妙汤治疗痛风性关节炎36例临床观察

目的:观察新加四妙汤治疗痛风性关节炎的疗效。方法:将痛风性关节炎患者64例分为两组,中药组36例予新加四妙汤治疗,西药组28例予立加利仙(苯溴马隆)及芬必得治疗,观察两组治疗前后临床疗效、血尿酸及血沉的变化。结果:治疗组在改善临床症状,降低血尿酸、血沉等方面优于对照组(P<0.05)。结论:新加四妙汤对痛风性关节炎有较好的疗效,能够降低痛风性关节炎患者的血尿酸和血沉。     

拉美金融脆弱性的根源及启示

拉美国家普遍具有金融脆弱性这一特征。这一现象归因于结构缺陷、汇率制度僵化、过早金融自由化、高度财政赤字化和债务化等多个方面。它带给发展中国家的启示是应选择适宜的汇率制度、外汇与债务管理制度、宏观经济政策 ,以期保持经济长期可持续发展     

用世界历史理论解读现代社会的开放性

开放是世界历史发展的必然要求,也是现代社会的基本属性。开放的历史必然性蕴涵在资本主义生产方式与商品经济相结合所开创的世界历史中。社会主义的产生和发展都离不开世界历史。因此,社会主义是在经济、政治、思想文化等方面都必须与整个世界进行双向沟通和交流的开放型社会,开放既是实现社会主义现代化的手段,同时也是社会主义的一个基本属性。
