Psychological mechanisms of investors in Chinese Stock Markets

The study investigated the psychological mechanisms of risky investment behaviors in Chinese Stock Markets. A 42-item questionnaire was developed and distributed to 1547 individual investors recruited by stratified random sampling from Nan Fang Bond Company. A speculative orientation and a low level of risk perception among Chinese investors were revealed. The results also showed that investors were deficient in investment knowledge and skills. Structural equation modeling was used to generate a risk perception-mediated model for investment behaviors. We found that information from organizational/institutional level can precipitate low risk perception and policy-oriented speculation of investors, which could be accounted for by the collectivistic culture in China and may not be beneficial to risk management in Chinese Stock Markets. Suggestions were made regarding the further development of stock markets in China.

Saving Performance in Individual Development Accounts: Does Marital Status Matter?

Research indicates that marriage has a large effect on reducing the risk of poverty and is associated with a higher probability of attaining affluence over the life course when compared with nonmarriage. Using data from the American Dream Demonstration (N =2,364), this study compares savings performances of married and unmarried low‐income participants in a matched savings program—Individual Development Accounts. The results indicate that both married and unmarried low‐income participants can save in Individual Development Accounts. After controlling for program and other participant characteristics, there were no significant differences in savings between married and unmarried participants. We further examined possible factors that are associated with Individual Development Account savings performance for these two groups.

Operating Characteristics of a Subset Selection Procedure Applied to a Hybrid Randomized Response Model

The operating characteristics (OCs) of a subset ranking and selection procedure are derived for the hybrid randomized response model developed by Jia and McDonald (2009 Jia, F., McDonald, G. (2009). Analyzing hybrid randomized response data with a binomial selection procedure. Commun. Statist. Theor. Meth. 38:784807.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). The OCs include the probability of a correct P(CS), the individual selection probability γ_i, and the expected subset size E(S), under the slippage configuration or the equi-spaced configuration. An example comparing failure rates of contraceptive methods is used to illustrate the use of these new results.     

Perceived group cohesion versus actual social structure: A study using social network analysis of egocentric Facebook networks

Research on group cohesion often relies on individual perceptions, which may not reflect the actual social structure of groups. This study draws on social network theory to examine the relationship between observable structural group characteristics and individual perceptions of group cohesion. Leveraging Facebook data, we extracted and partitioned the social networks of 109 participants into groups using a modularity algorithm. We then surveyed perceptions of cohesion, and computed group density and size using social network analysis. Out of six linear mixed effects models specified, a random intercept and fixed slope model with group size as a predictor of perceived group cohesion emerged as best fitting. Whereas group density was not linked to perceived cohesion, size had a small negative effect on perceived cohesion, suggesting that people perceive smaller groups as more cohesive. We discuss the potential of social network analysis, visualization tools, and Facebook data for advancing research on groups.     

Empowering leadership and contextual ambidexterity – The mediating role of committed leadership for continuous improvement

Organisations nowadays try to be ambidextrous, that is, to balance exploitation and exploration, at the level of the organisational unit, or even at the individual level. Recent studies found that important drivers for contextual ambidexterity are a high level of empowerment and an orientation towards continuous improvement (CI) and innovation. It is, therefore, to be expected that empowering leadership and leader commitment to CI are associated with contextual ambidexterity. However, literature about the relationships between empowering leadership, committed leadership for CI and contextual ambidexterity is scant. Based on two separate survey studies, we validated both the relationship between empowering leadership and contextual ambidexterity, and the mediating effect of committed leadership for CI in the organisational unit level and the individual level. The managerial implications of this research is that organisations that want to facilitate contextual ambidexterity should not only empower employees so that they can decide more independently on how to organise their time and make choices when they conduct exploratory activities and when they perform exploitative activities. Management must also act as committed ambassadors for CI, as CI functions as an integration mechanism to create both alignment and adaptability, and hence contextual ambidexterity.     

The Optimal Allocation Combination for the One-Sided Sequential Screening Procedure Based on the Individual Misclassification Error

In this article, the expected total costs of three kinds of quality cost functions for the one-sided sequential screening procedure based on the individual misclassification error are obtained, where the expected total cost is the sum of the expected cost of inspection, the expected cost of rejection, and the expected cost of quality. The computational formulas for three kinds of expected total costs are derived when k screening variables are allocated into r stages. The optimal allocation combination is determined based on the criterion of minimum expected total cost. At last, we give one example to illustrate the selection of the optimal allocation combination for the sequential screening procedure.
