供应商家长式行为导向与经销商建言行为：人情的调节作用

以渠道行为理论、中国本土社会心理学理论和家长式领导理论为基础，从中国传统文化的视角提出供应商家长式行为导向这一构念，将其细分为立威行为导向和施恩行为导向两个维度，并在供应商经销商关系中实证检验供应商家长式行为导向对经销商建言行为的影响以及人情的调节作用。以327份来自经销商的调查问卷为基础，研究结果显示：供应商家长式行为导向对经销商建言行为具有显著影响，立威行为导向会抑制经销商的建言行为，人情会削弱立威行为导向的抑制作用；而施恩行为导向会促进经销商的建言行为，人情会强化这一影响。     

沪深股市风险度量中半参数ES模型的实证检验

目前度量预期不足(Expected Shortfall, ES)的风险技术大多基于参数模型,其建模过程避免不了对收益的分布类型做出假定,但这些分布往往与现实相悖。为此,介绍两种重要半参数模型,即CARE模型和CARES模型,并应用我国2007-2016年上证综合指数与深证成分指数的相关数据评估模型优劣。结果表明：CARES模型与CARE模型在度量我国股市风险中都具有较好的效果,但两者比较,CARES模型明显优于CARE模型。因此,CARES模型能作为我国股市风险度量工具中的一个重要补充。

The bivariate GARCH approach to investigating the relation between stock returns,trading volume,and return volatility

We use a bivariate GJR-GARCH model to investigate simultaneously the contemporaneous and causal relations between trading volume and stock returns and the causal relation between trading volume and return volatility in a one-step estimation procedure, which leads to the more efficient estimates and is more consistent with finance theory. We apply our approach to ten Asian stock markets: Hong Kong, Japan, Korea, Singapore, Taiwan, China, Indonesia, Malaysia, the Philippines, and Thailand. Our major findings are as follows. First, the contemporaneous relation between stock returns and trading volume and the causal relation from stock returns and trading volume are significant and robust across all sample stock markets. Second, there is a positive bi-directional causality between stock returns and trading volume in Taiwan and China and that between trading volume and return volatility in Japan, Korea, Singapore, and Taiwan. Third, there exists a positive contemporaneous relation between trading volume and return volatility in Hong Kong, Korea, Singapore, China, Indonesia, and Thailand, but a negative one in Japan and Taiwan. Fourth, we find a significant asymmetric effect on return and volume volatilities in all sample countries and in Korea and Thailand, respectively.     

企业社会资本对渠道权力与依赖的影响

传统渠道权力与依赖研究将研究视野局限在由两个渠道成员构成的二元渠道关系内,关注关系内的资源依赖特征而缺少对关系以外更大范围的渠道关系网络的关注。针对这一缺陷,文章引入了社会资本理论,并实证性地考察了制造商社会资本对其渠道权力和经销商依赖的影响。研究发现,制造商的社会资本对其渠道权力有显著的正向影响,但对经销商的渠道依赖没有显著影响。同时,以中国本土社会心理学理论为基础,研究证实在中国文化背景下渠道权力作为依赖的前因变量对其有显著的正向影响。

Fitting and testing for the implied volatility curve using parametric models

Numerous issues have arisen over the past few decades relating to the implied volatility smile in the options market; however, the extant literature reveals that relatively little effort has thus far been placed into comparing the various implied volatility models, essentially as a result of the lack of any theoretical foundation on which to base such comparative analysis. In this study, we use a comprehensive options database and employ methods of combining the various hypothesis tests to compare the different implied volatility models. To the best of our knowledge, this is the first study of its kind to address this issue using combination tests. Our empirical results reveal that the linear piecewise model is the most appropriate model for capturing the implied volatility smile, with additional robustness checks confirming the validity of this finding.
