逐差法和Origin软件在金属电阻率实验数据处理中的应用

实验的数据处理工作普遍被认为是繁琐、枯燥的,并被尽量回避。文章分别采用逐差法和Origin软件处理了金属电阻率实验数据,展示了Origin软件在数据处理和分析过程中具有精确、高效、直观等优点,值得在物理实验中进一步推广应用。     

WTO《原产地规则协议》对贸易的影响

多边贸易体制中的"原产国标记"与乌拉圭回合《原产地规则协议》对用于海关贸易统计的一般原产地规则做出了原则性规定,但对优惠原产地方面却没有制订出为世界各国所接受的多边规定,致使优惠原产地规则被滥用,对世界贸易产生不均衡性影响。我国原产地规则领域存在的问题突出表现为立法滞后、法规不周详不健全;出口货物原产地授予标准过宽,致使原产地规则不具备宏观调控和投资结构政策导向功能;进口商品原产地认定标准过宽,危害我国幼稚产业的健康发展等方面,导致我国加工贸易减少,对我国吸引外商投资的环境改善将产生不利影响。     

The economics of rules of origin

Rules of origin of free trade arrangements limit the use of inputs from outside the preferential trade zone. A government negotiating a future FTAcan manipulate these rules in order to achieve national welfare objectives. The correct definition of rules of origin may help to enhance demand for domestically produced goods, promote national technological development, and maximize labour income. This paper proves that a more stringent rule of origin implies an increase of demand for the domestic factor if the substitution effect prevails over the effects caused by the decrease of the scale of operation in the domestic plant, and the reallocation of output between domestic and foreign plants. We further show that policy decisions regarding rules of origin that intertemporally maximize welfare and foster domestic technological evolution should be made at the greatest level of disaggregation that is feasible.     

对我国发展东南亚华人华侨寻根旅游的思考

International commodity taxation in the presence of unemployment

In this paper, we evaluate the impact of commodity tax competition on welfare and employment under the destination and origin principles, when the labor market is imperfectly competitive owing to a binding fixed wage. Our main finding is that commodity taxation causes an employment externality whose signs may be opposite under the two principles. While tax competition leads to inefficient tax rates under both principles, we also prove that the origin principle guarantees lower unemployment and higher welfare when the fixed wage is high. Finally, we show that the employment externality still exists in a standard union model of wage determination.     

政府视角下以区域联想为核心的区域品牌伞构建研究

为了应对区域品牌建设中出现的一系列问题，区域管理者们不得不采取新的策略来发展区域经济。某些地区已经尝试将品牌伞策略应用于区域品牌的建设，构建区域品牌伞。探讨了以区域联想为核心的区域品牌伞的基本架构，并提出了影响作为区域品牌伞核心价值的区域联想可转移性维度。在国内外相关研究基础上，通过定性分析，提出区域品牌伞就是将区域品牌撑开成为伞状品牌，直接与产品相结合，作为其品牌或品牌一部分，构建一个以区域品牌为上层品牌，涵盖区域内一系列产品或品牌的区域品牌层级结构；影响区域联想可转移性的维度包括：强度、独特性、相关性、相似性、偏好性及抽象性。     

Consumer ethnocentrism,product necessity and quality perceptions of Russian consumers

Retail buyers in Russia have indicated that some customers have expressed a desire to purchase domestically produced products over imports. Consumer ethnocentrism has been proposed as a measure to provide retail buyers with the information necessary to market to these consumers. The purpose of this research is to determine if perceived product quality of products differs based on country of origin, product necessity and consumer ethnocentric tendency. A repeated measures ANOVA test indicates that perceived quality differs by necessity, by product, by country. A consumer ethnocentrism effect on the overall model, however, was not significant. We conclude that Russian consumers do perceive differences in product quality based on country of origin and product necessity, but that consumer ethnocentrism does not have an effect on perceived product quality.

Climate reversals and the transition to agriculture

The transition to agriculture is generally acknowledged to be the economic foundation for population growth over the last 10,000 years and for modern civilization itself. Dates for pristine transitions to agriculture have become a key input into empirical work on economic growth over the very long run. We propose a model of the transition in which population and technology respond endogenously to climate. The available data on the southwest Asian case, other cases of pristine transition, and cases of non-transition are consistent with our model, but often inconsistent with rival explanations. In addition, our theory of the origins of agriculture has implications for instrumental variable strategies that can be used in empirical research on long run economic growth and development.
