Reconsidering the Relationship between Inflation and Relative Price Variability

It has long been popularly believed that the relationship between inflation and relative price variability (RPV) is positive and stable. Using disaggregated CPI data for the United States and Japan, however, this study finds that the relationship is neither linear nor stable over time. The overall relationship is approximately U‐shaped around a nonzero threshold inflation rate. RPV therefore changes not with the inflation rate per se, but with the deviation of inflation from the threshold inflation rate. More importantly, the relationship is by no means stable over time but instead varies significantly in a way that coincides with regime changes of inflation or monetary policy. The relationship was positive during the period of high inflation of the 1970s and the early 1980s, as has been documented by a number of previous studies, whereas it takes a U‐shape profile during the Great Moderation. The results are robust to the use of core inflation, which excludes the traditionally volatile prices of food and energy. This paper then presents a modified version of the Calvo‐type sticky price model to describe the observed empirical regularities. Simulation experiments show that the modified Calvo model fits the data well, and that the underlying relationship hinges upon the degree of price rigidity, which is systematically related to inflation regime. For countries and periods with low inflation rates, the relationship takes a U‐shape as price adjustment is more sticky. In a high‐inflation environment, when price setting becomes more flexible, the U‐shaped profile vanishes.     

我国区域经济安全动态监测分析

本文在界定我国区域经济安全内涵的基础上，通过国家经济安全指标依经济区域分解法，对影响我国经济安全的重点区域进行了一次全面动态的监测评估，定量研究发现：（1）2005-2009年，我国经济安全处于中度到低度不安全状态，其中影响我国经济安全的外来风险的85%集中在东部沿海七大省（市），经济风险省域高度集中，不利于分解我国的经济不安全状态，但近5年有缓慢下降态势。（2）我国经济安全防范能力的42%来自于东部沿海七大省（市），呈现低度集中结构，但近3年有缓慢上升态势。（3）2005-2009年，七大省（市）对全国经济安全的总体影响度为68%，经济风险呈现中度集中，但近5年有逐渐下降态势。（4）广东省对全国经济安全的影响度最高（19%），江苏省第二（13%），上海市第三（11%），浙江省第四（8%），山东省第五（7%），北京市（5%）与辽宁省（5%）并列第六位。     

The Influence of Consumer Degree of Knowledge on Consumer Behavior: The Case of Spanish Olive Oil

This article analyses the influence of perceived quality measured across intrinsic and extrinsic attributes on satisfaction and consumer loyalty for a traditional food product as with PDO (Protected Designation of Origin) olive oil “Aceite del Bajo Aragón.” In addition, the article highlights the influence of consumer's degree of knowledge on these relationships. The results suggest that the main drivers to explain consumers' satisfaction and loyalty are the perceived quality of the intrinsic attributes (color, appearance, flavor, etc.). However, when consumers are classified attending to their degree of knowledge the main explanatory variable of satisfaction and loyalty of the more experienced consumers are the extrinsic attributes of the product (brand name, place of origin, images associated to the product, etc.). These findings allow us to develop important managerial implications for building a brand image for a PDO.

北京市入境旅游与饭店旅行社的耦合协调度研究

基于2001—2010年北京市入境旅游和饭店旅行社的各指标数据,首先通过相关分析,筛选出与北京市入境旅游发展存在相关关系的饭店旅行社参量,然后借助熵值法,计算出各个参量的权重及评价值,最后建立耦合协调度模型,对入境旅游—饭店旅行社的耦合协调度进行了实证研究。结果发现,十年间,其耦合度一直处于拮抗阶段,但耦合协调度水平变化幅度较大,2003年达到低谷,属于中度失调,2010年达到最高值,属于中级协调。因此,北京市饭店旅行社的发展仍不能有效的支撑其入境旅游的发展,亟待提升和完善。     

普通小球藻对直接大红4B染料的降解作用研究

利用紫外-可见吸收光谱、高效液相色谱、傅立叶转换红外光谱分析以及溶液pH值测定,研究普通小球藻对直接大红4B染料溶液的降解作用。结果表明:普通小球藻对染料的降解必须在光的协同作用下进行,模拟太阳光的协同降解效果最好;染料的降解效果随普通小球藻的浓度与照射光强度的增加而增强,掺藻浓度16×108 cells/L的染料溶液,光照5 h的脱色率达到86%以上,降解速度在染料浓度比较高的初期较大;普通小球藻在对直接大红4B溶液的降解过程中不会产生中间产物;随着降解时间的延长,溶液的pH值在不断降低。     

Renminbi Internationalization： Progress, Prospect and Comparison

Using principal component analyses, this paper constructs two internationalization indices for the renminbi (RMB) and 32 other major currencies. We find that the RMB's currency internationalization degree index (CIDI) is still low, and far behind the 4 most important international currencies. In 2009, it was ranked 18th among all important international currencies. However, in terms of the currency internationalization prospect index (CIPI), the RMB has remained the world's fifth highest since 2006. Although it is still far behind the US dollar and the euro, surpassing the ranking of the yen and the pound is possible in the near future. The dramatic difference in the ranking between the CIDI and the CIPI is a result of China's tight capital account control, the usage continuity of international currency due to network externalities, and the narrow foreign exchange and imperfect financial markets. Hence, to a large degree, the RMB's potential as an international currency depends on China's capital account liberalization.     

基于区域协调发展的长江上游经济带的战略地位与发展定位

长江上游经济带肩负着引领西部广大欠发达地区实现经济社会协调发展的重要历史使命，其发展在西部大开发中具有重要的战略地位和作用。长江上游经济带的战略取向应为：对内实施地区联合发展模式，对外充分利用资源优势，实现与长江中下游的良好对接；其发展定位应是：注重特色产业和战略产业的发展，以成渝经济区为增长极。以城市化和工业化战略辐射和带动整个长江上游经济带发展，并实现生态建设和经济建设的有机结合。
