A dynamic factor model framework for forecast combination

A panel of ex-ante forecasts of a single time series is modeled as a dynamic factor model, where the conditional expectation is the single unobserved factor. When applied to out-of-sample forecasting, this leads to combination forecasts that are based on methods other than OLS. These methods perform well in a Monte Carlo experiment. These methods are evaluated empirically in a panel of simulated real-time computer-generated univariate forecasts of U.S. macroeconomic time series.     

服务型领导供求匹配一致性与创造力：内在动机与主动性人格的作用

服务型领导有效性取决于领导者和下属双方匹配的一致性,但现有研究局限于仅从领导或下属单一视角考察服务型领导的影响。基于个体-环境匹配理论,对服务型领导供求匹配一致性与创造力的关系进行分析,探讨追随者内在动机的中介作用与追随者主动性人格的调节作用。通过对200个领导与726个员工的配对数据进行多项式回归与响应面分析,结果发现：与服务型领导低匹配（低供给-低需求）相比,追随者的内在动机在服务型领导高匹配（高供给-高需求）时更高;服务型领导供求匹配通过追随者内在动机影响创造力;追随者主动性人格在服务型领导供求匹配与追随者内在动机之间并不存在显著调节作用。     

Specific customer knowledge and operational performance in apparel manufacturing

Customer knowledge is an important organizational asset that can be exploited to yield competitive advantage to a firm. However, empirical research on the application of customer knowledge to improve operational performance has been lacking in operations management. In this study we explore how customer knowledge can be used to improve operational performance under a supply chain environment in the clothing industry. We first conceptualize the relationship between customer knowledge and operational performance and delineate their attributes based on a review of the pertinent literature. We then formulate several hypotheses based on past studies and interviews with experienced industry personnel. We develop a self-reported questionnaire to collect data to test the hypotheses. Finally, we conduct a number of regression analyses to identify the key attributes (constructs) of customer knowledge that have a significant impact on operational performance. This paper contributes to research by demonstrating that there are relationships between specific customer knowledge and different facets of operational performance, and provides practitioners in clothing manufacturing with managerial insights on how to leverage customer knowledge for operational performance improvement.     

Strategic orientation of high-technology firms in a transitional economy

Strategic orientation is a critical factor for a firm's competitiveness in a transitional economy context but it is understudied in the current literature. This article examines the antecedents of strategic orientation from both the socio-cognitive and resource-based view perspectives. The study posits that the strategic orientations of firms in a transitional economy context are influenced by the top managers’ cognitions and organizational resources. Based on a national survey of high-technology firms in China, the study finds that a stronger market-focused strategic orientation was facilitated by managerial cognitions about the future of the industry and current operation and performance of the firm, as well as organizational resources including an R&D infrastructure, technological alliance, and top managers' foreign experience. The study confirms that strategic orientations should be examined from multiple theoretical perspectives.     

Price Volatility of Commercial and Residential Property

This article studies the relative volatility of commercial and residential property prices. Empirical evidence of commercial property prices being more volatile than the prices of residential property is presented. Models are built following that of Lucas. Theoretical statements are derived to show the exact conditions under which the observations arise. The cases of fixed supply and flexible supply are considered separately.     

The Tragedy of the Commons Revisited

The Malthus–Hardin tragedy of the commons is formulated as a dynamic game between "clans". At each date a member of a clan desires more newborns of her/his type and more current consumption, harvested from the commons. Equilibrium in the dynamic game yields a steady state level of per capita consumption and a steady population level for each clan (births equal deaths). Four outcomes are obtained, depending on the assumptions about the discount rates of members of a clan and about the mode of competition for "large populations" for each clan. Lack of property rights for agricultural land in the commons leads to equilibrium with excessive populations and low per capita consumption.     

Insiders maintain voice: A psychological safety model of organizational politics

We present a psychological safety model of organizational politics to account for the effects that exposure to organizational politics has on voice behavior. In particular, we hypothesize that psychological safety mediates the negative relation between organizational politics, as perceived by employees, and their voice behavior. Moreover, we examine the extent to which perceived insider status alleviates the main effect of organizational politics and the indirect effect of psychological safety. Using a sample of 283 supervisor–subordinate dyads in six electronic companies at two time points in China, our results fully support the hypotheses and provide new directions for politics and voice research.     

The moderating roles of job control and work-life balance practices on employee stress in the hotel and catering industry

This study investigated the relationships among job stressors, coping resources, and job stress. Data were collected from food service employees (n = 255) in the hotel and catering industry. Hierarchical regression showed main significant effects of job demands and job control and three-way (job demands × job control × work-life balance practices) interactions on job stress. The results further demonstrated that high job demands coupled with low job control and the availability of work-life balance practices resulted in a higher level of stress. Implications for Karasek's job demand–control model, managerial practice and future research are provided.
