The enlargement of the euro area: differences in relative inflation

This paper investigates the structural determinants of relative inflation (i.e. the inflation of non‐tradables vs tradables) in the context of overall inflation differentials in the EU. The analysis is based on the Bergstrand theoretical model. This framework incorporates three alternative hypotheses of relative inflation (Harrod–Balassa–Samuelson, relative factors endowment, and demand effects). Due to the lack of reliable data on capital stocks only a curtailed version of the model is tested here empirically. The various specifications of the model are estimated for the majority of EU countries, using the Pedroni panel group mean FMOLS estimator. In general, relative labour productivity and demand factors turn out to be significant and correctly signed, though evidence in favour of the latter effect seems to be less robust. In addition, differences in the determination of relative prices between the new and old EU Member States are found. They seem to be consistent with theoretical considerations and the transition phenomenon. The estimation results are very sensitive to the definition of non‐tradables. The paper also discusses policy implications for overall inflation, stemming from relative price models. It questions the usefulness of relative inflation models for the analysis of overall inflation differentials and practical policy decisions.     

商标法第三次修订的若干思考

商标法对保护市场经济的有序发展发挥着巨大作用,与人们的生活息息相关。现行商标法已不能满足商品经济的发展。修订商标法应保留相对理由审查制度,应加大对恶意行为人的处罚,驰名商标标准应增加商品质量优异和良好售后服务的内容。     

均匀圆阵的测向模糊研究

在高分辨阵列测向系统中,均匀圆阵(UCA)是一种广泛使用的阵列结构。利用均匀圆阵的阵列流形的微分几何作为分析工具,对实际中常用的几种均匀圆阵的测向模糊进行了大量的计算机仿真试验,定量地给出了这些阵列的测向模糊方向和相应的秩,揭示了均匀圆阵的测向模糊性能与其阵元数和孔径之间的关系,得出了一些有实际意义的结论。这对工程应用时均匀圆阵的选择和构造具有很强的参考价值和指导意义,可以避免系统设计的盲目性和随意性。     

基于管理可能集的管理有效性动态评价指标体系研究

为消除组织间客观基础条件差异对绩效评价结果的影响,对能真正反映管理好坏程度及能力对绩效贡献的二次相对评价模型及其可测性进行了研究,在此基础上提出了管理可能集的概念,并通过管理可能集分析管理有效性的可能性,并建立管理有效性评价的动态指标体系。同时,针对管理有效性的可测性分析,可真正做到对不同评价单位都有激励作用,从而有利于寻找差距,分析经济行为低效的主要原因,调动人们提高经济效率与科技进步的积极性。     

Sequential point estimation of normal mean under LINEX loss function

A sequential point estimation of the mean of a normal distribution is considered under LINEX loss function. The regret of sequential procedures are obtained. Furthermore, it is shown that a sequential procedure with the sample mean as an estimate is asymptotically inadmissible. An accerelated stopping time is also considered. Received: December 1999     

Biases in demand analysis due to variation in retail distribution

Aggregate demand models typically assume that consumers choose between all available products. Since consumers may be unwilling to search across every store in a given market for a particular item, this assumption is problematic when product assortments vary across stores. Using supermarket scanner data for five product categories we demonstrate that approximately one third of products have limited retail distribution, which account for one fourth of dollar sales. Monte Carlo analysis demonstrates that the level of limited product availability observed in the data can significantly bias the results of aggregate demand models that incorrectly assume all consumers in a given market face the same choice set.     

南欧3国社会救助制度反贫困脆弱性：经验分析和比较反思

对南欧的希腊、意大利和西班牙3国的最低收入计划的反贫困经验进行了讨论，从相对贫困率变化的角度看，南欧3国社会救助制度对于贫困减少仍存在脆弱性。同时，分析、对比了中国城市最低生活保障制度对于城市贫困减少的效果，结果表明，就相对贫困而言，贫困减少效果目前还较为有限。最后，就制度设计、政策支持和价值取向等方面提出了思考。

Public Debt and Economic Growth in Emerging Market Economies

This paper empirically studies the relationship between public debt and economic growth for selected emerging market economies by performing panel data estimations. The results reveal a statistically significant positive correlation between public debt and the subsequent growth rate of per capita gross domestic product (GDP). Population and investment are also positively correlated with per capita growth, whereas the initial level of real GDP per capita exerts a negative influence on growth, implying conditional convergence. Other variables such as the inflation rate, the trade balance or the exchange rate do not yield a statistically significant effect with respect to economic growth.     

The role of CEO relative standing in acquisition behavior and CEO pay

In this study, we develop and test a theory of CEO relative pay standing. Specifically, we propose that CEOs with negative relative pay standing status (underpaid relative to comparison CEOs) will engage in acquisition activity, as a self‐interested means of attempting to realign their pay with that of their peers. We further propose that, when CEOs with negative relative pay standing acquire, they will tend to finance those acquisitions more heavily with stock than cash, to mitigate the risk associated with those deals. Finally, we argue that acquisition activity will partially mediate the influence of CEO negative relative pay standing on subsequent CEO compensation increases; however, that pay growth will come primarily in the form of long‐term incentive pay. Our results support our predictions. Copyright © 2014 John Wiley & Sons, Ltd.
