The Value of Adjusting the Bias in Recommendations: International Evidence

The financial literature has shown that both earnings forecasts and investment recommendations are optimistically biased. However, while the bias in earnings forecasts has decreased over time and even some recent studies show that they are no longer optimistic, in the case of investment recommendations this bias still remains relatively constant over time. Therefore, it seems that recommendations are less credible to investors than earnings forecasts. The vast majority of recommendation studies have been carried out at the country level. In this paper, we use an international context to study whether profitable investment strategies exist when adjusting the recommendation bias of each analysed country. The adjustment we propose to correct this bias takes into account the differences across countries, and also varies in time to correct for the changes in bias over time within countries. Our empirical results show that there are in fact significant differences in the level of bias among countries, with the US and the UK being the countries with the highest bias. Second, the adjusted consensus portfolios are more orthogonal to typical investment styles (size, book‐to‐market and attention) and we find that investors could implement a higher number of profitable investment strategies using this adjusted measure. In this line, the results show that the countries with the lowest bias obtain the highest risk adjusted abnormal returns. Third, our work entails a practical implication, as it shows the value embedded in a simple necessary adjustment in the global asset management context. This is an important result showing that profitable investment strategies exist when considering a global portfolio based on adjusted recommendations.     

Using and Influence Level of Information to Explain the Non-consensus Process Loss

Much of the Group Support System (GSS) literature comparing GSS groups with manual groups has produced contrarian results. One of the more confusing is that GSS groups have a higher level of non-consensus than manual groups. Lack of consensus in GSS groups is considered to be a negative aspect of GSS. This paper argues that low levels of consensus are not necessarily harmful and should be expected given the assumptions about GSSs. This study uses an alternate measure to compare face-to-face groups with GSS groups; an influence level of information. Experimental results using an influence level of information show no difference between face-to-face group members and GSS group members. We discuss these implications, as well as additional directions for further consensus research.     

新自由主义思潮的全球化历程及其影响

新自由主义思潮在向全球扩张蔓延的过程中,对拉美、东欧和前苏联国家产生了巨大而深刻的影响。对新自由主义的危害,正处于改革发展关键阶段的中国应有清醒而足够的认识。     

An Extension and Further Validation of the Potential for Conflict Index

The Potential for Conflict Index (PCI) was developed to facilitate understanding and applicability of leisure, recreation, and human dimensions findings to managerial concerns. The PCI ranges from 0 (minimal potential for conflict) to 1 (maximum potential for conflict) and simultaneously describes a variable's central tendency, dispersion, and shape using a graphic display. This article (a) describes applications of the original formulation of the PCI (PCI₁) to illustrate the statistic's practical utility, (b) introduces the second generation of the PCI (PCI₂) and discusses enhancements incorporated in this version, (c) describes efforts to validate the PCI₂, and (d) offers suggestions for continuing the empirical validation process. Programs for calculating, graphing, and comparing PCI₂ values are freely available from http://welcome.warnercnr.colostate.edu/~jerryv.     

对农村承包土地调整制度的反思——基于治理逻辑的视角分析

我国农村承包土地调整的变化已超出了法律的预期,重新解析农地调整的价值基础和调整因素,有利于构建更合乎农民需求的土地调整制度。农村承包土地的调整在法律逻辑层面与治理逻辑层面有很大的不同,政策、立法层面的法律实践与农村实际有一定的差距,而治理层面上,用经验材料从另一方面分析法律调整制度,以及村庄自身治理对法律实践的影响,才能用村庄本身的内部逻辑体现出调整根源。在调整问题上的形式和主体性同样有极大的区别,同样是支持土地调整的地方性规范,规范的性质其实并不相同,其背后的地方性共识的基础也不相同。让土地调整的法律逻辑遵从治理的逻辑,探寻治理的本质,才不至于让法律淹没于治理的逻辑之中。     

基于扩散策略的分布式协作频谱检测

分布式认知网络中,认知用户通过与相邻用户交换检测量信息,达到全网一致,实现对主用户信号的检测。为了提高网络检测量信息的收敛速度,提出了一种基于扩散策略的分布式协作检测算法。在该算法中,将最大最小特征值检测算法的检测量作为交换的初始信息,构造自适应矩阵和融合矩阵作为加权因子对认知节点状态值进行迭代更新,实现全网认知用户检测量信息一致,各认知用户独自根据融合的检测量信息,进行最终的检测判决,确定主用户是否存在。仿真结果表明,该算法在网络收敛速度和检测性能上较共识策略和非合作检测有不同程度的提升。

Reducing microbiological risk in the kitchen: piloting consensus conference methodology as a communication strategy

Foodborne diseases are a major public health problem. Improper storage and food preparation at home can favour microbial contamination of food. Consumers play a crucial role in controlling this risk. To reduce exposure to risk, it is essential to provide information and guidance on contamination management in the home. The aim of this study was to pilot a method of participatory communication addressed to young consumers and designed to reduce the microbiological risks associated with the consumption of meat products. The methodology was based on application of the ‘consensus conference’ model on food safety issues. The consensus conference served not only as a participatory strategy to share knowledge but also as a method for sharing in the development of risk communication content (guidelines) to be disseminated to the reference target. Young people’s perceptions, habits and behaviour in the kitchen were explored in the preparatory stage of the consensus conference by means of a survey and a focus group. Three consensus conferences were held in Italy attended by 60 university students (19 and 22 years old). Application of the consensus conference model as a communication process proved to be an effective opportunity to engage young consumers and experts on the topic of food safety. This discursive participation approach was broadly welcomed by the participants. Specifically, direct interaction with the experts was considered to be an important part of the communication process. The findings of the project were used to select concise communication content based on the perceptions, behaviours and fact-finding needs of the selected target. Publication of this content in the form of guidelines on microbiological risk management at home has enabled the results of the consensus conferences to be extended and the targeted communication material on risk reduction in daily food handling practices to be disseminated.     

Contribution of interest rate control to China’s economic development

China’s economy has grown at an unprecedented pace since 1978, which has resulted in a sustained improvement in the average living standard in China. A theoretical model is developed in the present study to analyze the role of interest rate control in China’s economic growth, where investment is primarily determined by interest rates available to firms and entrepreneurs. When the central bank regulates the interest rates and makes them below the equilibrium rate, high-level investment activities boost economic growth and introduce new technologies into the economy, which in turn promotes growth in labour productivity. As the current marginal product of capital is much higher than the interest rate, the output growth is much faster than consumption growth and exports become an important part of the economy. To maintain competitiveness of exports over a longer period, it is necessary to keep exchange rates low, which results in large foreign exchange reserves. When the export sector is losing its competitiveness edge due to increased labour costs and exports cannot digest the difference between output growth and consumption plus investment growth, interest rate control may lose its positive impact on economic growth.
