Financial risk taking in the presence of correlated non-financial background risk

This paper characterizes the stochastic deterioration resulting from taking a zero-mean financial risk in the presence of correlated non-financial background risk. We show in particular that it has an equivalent stochastic order as well as a necessary and sufficient “integral condition” that implies and is implied by a particular sense in which the stochastic deterioration can be decomposed into a “correlation increase” and a “marginal risk increase”. We further characterize a measure of aversion to the stochastic deterioration. These characterizations provide for a more general framework for formulating concepts of increases in risk and correlation and for better understanding risk management decisions governed by individuals’ attitudes to them.

Dialectical mind can be sweet toward crisis‐associated products/brands

Consumers’ thinking style (e.g., dialectical thinking), which is fundamental to cognition, has been paid inadequate attention in the consumer literature. This research explores the impact of dialectical thinking on Chinese consumer responses toward crisis‐associated products/brands. Findings in three experimental studies indicate that, in comparison to those primed with nondialectical thinking, consumers primed with dialectical thinking report higher levels of purchase intention and trust for a crisis‐associated product/brand. This is the case not just for products with Chinese cultural background, but also for products with western cultural background. Consumers’ perceived severity of crises moderates the impact of dialectical thinking, with a stronger impact in a highly severe crisis situation than in a less severe one. A survey study indicates a similar pattern. These findings are important in suggesting ways of encouraging Chinese consumers to be insistent on quality standard in order to better protect their consumer rights, and moreover, for multinational corporations on how best to respond and formulate strategies of handling product‐harm crises in the Chinese market.     

人力资本概念产生的分析

人力资本概念自从20世纪60年代由西奥多.舒尔茨正式提出以来,在经济学界受到了广泛的关注。按照英国著名经济思想史学家马克.布劳格的说法,"在鲍曼确切地把人力资本的概念的提出称为20世纪60年代的‘经济思想上的人力投资革命’以前,把在诸如保健和教育这样的社会服务上的支出当作与在物质资本上的投资一样的投资,是一件非同寻常的事情。"人力资本概念的提出无可厚非是观念上的创新与突破,但是在面对这种创新与突破的同时,许多的学者似乎误入歧途,仅仅对人力资本的概念做表面上的理解,脱离了它产生的社会背景、技术背景和理论背景。许多人置资本的内在规定性于不顾,牵强地对人力资本下定义。在这样的视角下,不仅工业时代有人力资本,就连远古时期也存在人力资本。文章希望通过从人力资本概念产生的角度分析人力资本概念的内涵,从而真正解释什么才真正属于人力资本的范畴。     

Assessing students’ equality of opportunity in OECD countries: the role of national- and school-level policies

This article analyses the relationship between equality of opportunity and the characteristics of the educational system, jointly considering country- and school-level policies. Because school social environment represents a fundamental channel in shaping educational opportunities, we consider all policies, recorded in PISA 2012 dataset, that affect the sorting of students to schools. We show that including sorting policies enriches the explanation of the socio-economic gradient, that is, the association between students’ performances and parental background, with respect to previous studies including only country-level features. The negative impact of early tracking on equality of opportunity is overvalued without including other sorting policies, while grouping students’ within-school by ability increases the socio-economic gradient and a greater students’ heterogeneity in the school reduces the gradient.     

CEO背景特征对公司风险承担的影响研究

以我国沪、深两市上市公司为研究对象,深入研究了CEO背景特征对公司风险承担的影响。研究表明:CEO年龄越大,越为保守和回避风险,倾向于降低公司风险承担;CEO任期越长,其专用性人力资本和管理防御程度越高,公司风险承担水平越低;CEO教育程度与公司风险承担显著负相关,当CEO在其他单位兼职时,公司风险承担水平相对较低。而CEO性别、职称对公司风险承担并没有显著的影响。文章为我们更好地理解上市公司的风险承担行为及CEO等高管的选拨与任命具有一定的启示意义。

Convenience food consumption in the Nordic countries and St. Petersburg area

Building on the theoretical framework provided by sociological research on eating practices, family meals, self‐cooked meals and time use, this study examines national differences and similarities in the use of convenience food in Northern Europe. The study draws on two quantitative sets of data, the primary data set (N = 8248) collected in 2012 in Denmark, Finland, Norway and Sweden, and the complementary data set (N = 800) collected in St. Petersburg area in 2013. In general, consumers’ attitudes towards convenience food were negative. Time saving was an important motivator for convenience consumption in all countries. The effects of other attitudes were diffuse and factors such as low cost, health effects, and taste of convenience food, affected convenience consumption differently in different countries. In the four Nordic countries women used less convenience food than men. In Finland and in Norway older respondents used convenience food less often than the young. Generally, the use of convenience food was most frequent among those living alone. The effects of education and occupation were small, implying that the phase of life is more important than social stratification in explaining convenience food consumption. In the St. Petersburg data, there were no differences related to social background.
