银行伙伴关系加剧了流动性冲击对银行的不利影响吗——基于中国银团贷款数据的分析

基于中国银团贷款数据,实证检验了流动性冲击时银行伙伴关系对银行融资成本、流动性创造水平和信贷供应的影响.研究结果表明,拥有更多伙伴关系的银行会更倾向于外部"购买流动性"而不是内部"储存流动性"的流动性管理策略;在面临流动性冲击时,通过银团贷款建立更多伙伴关系的银行会面临更高的融资流动性风险,削弱流动性创造能力和减少信贷供应数量;银行伙伴关系会促使银行放松内部流动性管理,最终在面临流动性冲击时带来不利后果.因此,商业银行应持有充足、优质的高流动性资产,切勿陷入同业资金"依赖症";监管当局需要强化对银行流动性风险的监管,避免过度依赖伙伴关系的短期同业资金而造成流动性危机.     

A NOTE ON SEMIPARAMETRIC ESTIMATION OF FINITE MIXTURES OF DISCRETE CHOICE MODELS WITH APPLICATION TO GAME THEORETIC MODELS*

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero.     

技术创新、金融创新与经济增长——基于中国省际面板数据

本文从实证分析层面对金融创新、技术创新与经济增长之间的作用关系进行探讨。基于我国 2000~2015 年省级面板数据,采用GMM估计方法,利用动态面板模型进行实证检验。结果表明：技术创新对经济增长的影响显著为正,单独的金融创新对经济增长起抑制作用,二者的交互作用则对经济增长起显著性正向作用。脱离实体经济的金融创新将抑制经济增长,也会间接阻碍技术创新对经济增长的影响。本文结合当前经济形势,从金融机构与创新企业相接轨共同提高创新水平、培养创新型人才等角度提出建议。

Drivers of customer decision to visit an environmentally responsible museum: merging the theory of planned behavior and norm activation theory

The main goal of this research was to merge the theory of planned behavior and the norm activation theory into one model and test its applicability in an environmentally responsible museum context. A filed survey was conducted at museums. Structural equation modeling was used to test research hypotheses. Results of the structural model comparisons revealed that the prediction power of our integrated model was superior to that of the theory of planned behavior and the norm activation theory. The proposed relationships among research constructs were generally supported. The mediating role of study variables was established. Additionally, the salient role of personal norm and attitude in generating museum travelers’ pro-environmental intention was identified. Overall, there was a strong support for the proposed theoretical model.     

Emerging youth tourism: fostering young travelers’ conservation intentions

Greening is one of the most important issues faced by the tourism industry today. Nevertheless, theoretical and empirical research on young travelers’ sustainable behaviors is scarce. This study developed a conceptual framework involving biospheric value, environmental concern, environmental awareness, ascribed responsibility, and moral norm in order to better explain young travelers’ pro-environmental decision-making process. A total of seven hypotheses were proposed and tested using structural equation modeling. Results revealed that the postulated theoretical model satisfactorily accounted for three dimensions of young tourists’ environmentally responsible intentions; the study variables are all significantly related; and the mediating impact of moral norm and environmental concern was evident. Moreover, the prominent role of moral norm in forming intentions was noteworthy. Our findings from the invariance test further indicated that environmental awareness and ascribed responsibility acted as moderators. The implications of these results are discussed.
