This paper empirically studies the occurrence and extent of asset stripping via undervaluing public assets during the mass privatization of state-owned and collectively owned enterprises in China. Using three waves of a national survey of private firms, we provide evidence that state-owned and collectively owned assets were substantially underpriced, indicating the presence of corruption during privatization. Further analysis shows that the extent of underpricing is more severe in regions with less market competition or weaker property rights protection, and more pronounced for intangible assets such as intellectual property rights and land use rights. When comparing firm efficiency between privatized firms and de novo private firms, we find that the former group continues to enjoy considerable preferential treatments, yet significantly underperforms the latter, possibly due to continued government control and intervention. Finally, we provide evidence that insider privatization is an important source of corruption during the privatization process.  相似文献

The exploration of option pricing is of great significance to risk management and investments. One important challenge to existing research is how to describe the underlying asset price process and fluctuation features accurately. Considering the benefits of ensemble empirical mode decomposition (EEMD) in depicting the fluctuation features of financial time series, we construct an option pricing model based on the new hybrid generalized autoregressive conditional heteroskedastic (hybrid GARCH)-type functions with improved EEMD by decomposing the original return series into the high frequency, low frequency and trend terms. Using the locally risk-neutral valuation relationship (LRNVR), we obtain an equivalent martingale measure and option prices with different maturities based on Monte Carlo simulations. The empirical results indicate that this novel model can substantially capture volatility features and it performs much better than the M-GARCH and Black–Scholes models. In particular, the decomposition is consistently helpful in reducing option pricing errors, thereby proving the innovativeness and effectiveness of the hybrid GARCH option pricing model.  相似文献

Self-classification is used as an a priori approach to tourist typology and market segmentation. However, skepticism still surrounds its ability to incorporate the multidimensionality of tourist behavior. This study seeks to empirically verify the efficacy of a single-item self-classification approach. The robustness of this self-classification measure is examined by comparing it to a data-driven multidimensional psychographic approach in terms of its ability to predict the behaviors of tourists toward food-related destination consumption. Results suggest that the single-item self-classification approach performs equally well as the psychographic approach in segmenting food-related consumption behaviors. The implications and limitations of this study are also discussed.  相似文献

This study investigates Chinese tourists’ views of nature, interest in animal experiences and their preferred natural landscape interpretation content from a generational perspective. Eight hundred and eight self-administered questionnaires were collected at Wulingyuan, a UNESCO World Natural Heritage Site, in China. It suggests that overall Chinese traditional cultural values and beliefs, notably the thinking of tian ren he yi (oneness of nature with humans), still have considerable impacts on Chinese tourists. They were found to have a strong sense of connection with nature and a preference for cultural interpretations of natural landscapes. Meanwhile, Chinese might be reaching a point of convergence in terms of attitude towards nature and animals with their Western counterparts, as reflected by their weak anthropocentric view, and strong ethical and aesthetic appreciation of animals, regardless of generation cohorts. Yet, the study shows significant generational gaps: older generations have a stronger connection with nature, are more concerned about environmental issues and show more support for the Western approach towards nature protection; the younger generations hold weaker anthropocentrism, and are more interested in animals, yet are less likely to learn about nature through tourism interpretation.  相似文献

Abusive supervision has received increasing attention in the field. However, few studies have qualitatively reviewed its latest developments. The current paper reviews 48 studies on abusive supervision using content analysis. We identify six emerging trends of abusive supervision, including inconsistency of abusive behaviors, comparison between perceived and objective behaviors, reciprocity, team-level climate, coworker effects, and comparisons between theoretical perspectives. Based on a review of those six trends and some emerging findings, we identify and validate the possible positive effects of abusive supervision from an integrated analysis. We also determine the moderating role that Asian culture plays in differentiating the negative and positive effects of abusive supervision. Specifically, we identify the differences between Asian and Western cultures, and then explore the moral mechanisms (i.e., violation of moral standards, conflict of moral principles) through which abusive supervision may exert positive effects in the Asian cultural context. Finally, we clarify our theoretical implications and provide suggestions for future research.  相似文献

整合组织动机和期望确认理论,从购买动机视角探讨企业突破性技术持续采用意愿的驱动机制。将购买动机分为效率动机、规范趋同动机和模仿趋同动机,阐述购买动机对突破性技术持续采用意愿影响的微观机理。以198家购买过云计算技术的企业为研究样本,实证检验购买动机与突破性技术持续采用意愿间的关系,并检验满意和认知锁定的中介效应。结果表明:购买动机正向影响突破性技术持续采用意愿,满意和认知锁定在购买动机与突破性技术持续采用意愿之间起中介作用,各购买动机的中介作用路径呈现差异化。其中,效率动机的作用路径被满意和认知锁定部分中介,模仿趋同动机的作用路径被满意部分中介,规范趋同动机的作用路径被认知锁定部分中介。研究结论打开了企业突破性技术持续采用意愿的“黑箱”,对于企业深入理解突破性技术持续采用意愿的驱动机制,促进突破性技术在持续采用过程中发挥真正价值具有重要借鉴意义。  相似文献
