国家主权信用评级质量检验方法研究

国家主权信用评级对当今国际经济和金融运行有着极为重要的影响力。但是,与其地位不相符的是,评级机构的评级结果事后多次被证明准确性和前瞻性较差。事先缺乏预警而事后大幅降级,甚至对加剧危机起到了推波助澜的作用。本文从国家主权信用评级质量的检验方法入手,系统分析了违约率和迁移率等传统方法在检验评级结果起到的作用及其不足,给出了检验评级质量的一般方法,并验证了该评级检验方法的科学性和准确性。     

美国信用评级市场与监管变迁及其借鉴

美国信用评级业发展已经有上百年的历史。市场高度垄断、严重的"顺周期"现象、利益冲突、金融市场及监管当局对评级的严重依赖是当今美国信用评级市场存在的四大问题。目前美国信用评级业形成了以行业自律为基础、NRSRO注册与美国证券交易委员会(SEC)直接监管相结合的信用评级监管体系。美国信用评级市场发展及监管变迁对我国的启示是:应逐步打破国际评级市场完全由美国评级机构垄断的现有格局,必须逐步构建有中国自身特色的本土评级体系,并将本土评级体系的培育与国内债券市场建设、"走出去"战略及人民币国际化战略结合起来,降低国内监管部门及市场主体对外部评级机构的依赖。     

Incompetency training: Theory, practice, and remedies

“Incompetency training” includes formal and informal instruction that consciously (purposively) or unconsciously imparts knowledge, attitudes, beliefs, and behavior (including procedures) that are useless, inaccurate, misleading, and/or will lower performance outcomes of the trainee versus no training or training using alternative training methods. “Imparts” in the definition refers to exposing a trainee to incompetency training; such exposure is not a guarantee that the training increases the trainee's incompetence. This editorial is to stimulate research interest among scholars in incompetency training theory, evidence, and the efficacy of remedies. The editorial offers an early workbench model of incompetency training theory. The theory includes the proposition that executives and associates in firms, academia, and government organizations consciously as well as unknowingly offer incompetency training in many contexts. Increasing trainees' vigilance and ability to recognize exposure to incompetency-training may help trainees to decrease the effectiveness (impact) of exposures to incompetency training—advancing incompetency training theory and knowledge of incompetency training practice may be necessary conditions for remedying negative outcomes that follow from trainees receiving such training. Available evidence supports the first proposition and, to a limited extent, the second proposition.     

Friends,family, or fools: Entrepreneur experience and its implications for equity distribution and resource mobilization

Who helps entrepreneurs raise the resources they need and how much equity does an entrepreneur distribute in return? We use a sample of 611 entrepreneurs in the U.S. to examine why some entrepreneurs are more likely than others to distribute ownership selectively to helpers. We find that entrepreneurs with specific industry experience and start-up experience are able to provide ownership more selectively and raise more resources from their helpers. We refine the categorization of social ties further to make a distinction between professional and familial ties to show that the ownership distribution and types of resource contributions vary by the mix of ties in the entrepreneur's helper network. Our findings have implications for theories of resource assembly, social structure and entrepreneurship, and organization design.

高管学术经历能提高企业分红吗？

文章选取2008-2017年沪深A股3449上市公司的23193个样本数据，实证检验了高管学术经历与企业分红水平的关系。研究发现，相比于高管无学术经历的企业，有学术经历高管企业的分红水平显著更高。高管的学术经历通过缓解融资约束，而不是缓解过度投资的路径显著提高企业分红水平。在进一步的研究中，通过引入外部治理与企业产权性质影响因素，发现外部治理较弱、非国有企业的情况下，高管的学术经历对企业分红水平的提高作用更加明显。采用倾向得分匹配法（PSM）、工具变量回归等检验结果依然稳健。研究丰富了高层梯队理论与企业分红相关性的文献，发现了中国情境下影响企业分红的新因素。     

The role of public space in constructing experience capital: A longitudinal analysis in the hotel context

Public space plays a primary role in shaping customers' hospitality experiences. Yet how public space conditions customers' experiential outcomes in accumulating capital for hospitality organizations remains underexplored. Inspired by the theory of psychological ownership, this research presents an in-depth analysis of the impacts of customers' public space experiences on their experiential outcomes using a longitudinal hotel industry dataset merging information from customer surveys, property performance, and surrounding accessibility insights. Findings revealed the positive effects of customers’ public space experiences on their overall service experiences, the perceived value of the experience, revisit intentions, and recommendation intentions. Moreover, hotel class, other customers, and surrounding accessibility were empirically verified as moderators conditioning the positive impact of public space. These findings offer valuable implications for theory and practice that are worthy of further exploration.

Experiencing forest products – An innovation trend by rural entrepreneurs

There is increasing emphasis on innovation as a driver of continued prosperity in the rural economy. Globalisation poses challenges to rural areas given technological advances and intensified competition in agricultural markets, ageing rural populations and expansion of urban areas. However, in recent years, the conception of rural areas has shifted from places of production to places of consumption. In line with an increasing urban demand for consumption of products and services close to nature within the rural landscape, we observe the emergence of experiential offers based around non-wood forest products (NWFP) where the consumer is closely connected to the harvesting and use of the products. In this paper, we examine how such intersecting demands have created new forms of market for NWFP, by analysing in-depth four innovative examples in Austria and the United Kingdom. Semi-structured interviews were conducted with the managers of these businesses, and cases were analysed through application of both the experience economy and the innovation systems approach. We found that all four businesses were on the one hand derived from traditional, regional cultural skills and values and, on the other hand, directly connected to new consumers’ demands. The apparent success of these emerging business models lies in the accretion of new social values onto traditional products. Thus creative approaches blending offers designed to enhance cosumers’ experiences into traditional sectors, such as forestry, would have potential in the future. However, our results indicate that there is a lack of institutional support for the development of such businesses in both countries. Better suited innovation policies and support structures would be important for mainstreaming or encouraging the development of similar businesses, innovations and knowledge.     

Testing loss aversion and diminishing sensitivity in review sentiment

This article analyzes the relationship between ratings and review sentiment by introducing, for the first time, the tenets of prospect theory. Specifically, we test loss aversion and diminishing sensitivity on a sample of 132,486 reviews and find that: first, negative deviations in ratings (receiving a service with worse performance than expected) bring about a higher impact on review sentiment than positive deviations of equal magnitude (receiving a service with better performance than expected), thus, confirming loss aversion; and second, regardless of whether the service received is better or worse than expected, variations in ratings closer to the reference point result in higher marginal impacts on sentiment than equivalent variations further away from the reference point, thus, proving diminishing sensitivity. These results have relevant theoretical implications related to the use of relative vs absolute measures and the cognitive bias involved, and managerial implications linked to meeting expectations and service recovery.
