Emerging bicycle tourism and the theory of planned behavior

In this study, we investigated the process of travelers’ decision formation for bicycle touring as a form of sustainable tourism activity. We extended the theory of planned behavior (TPB), using personal norm and past behavior as predictors and the attractiveness of unsustainable alternatives as a moderator. Results of the modeling comparison showed that our extended TPB model was superior to the original TPB in predicting intention. Our results from the structural analysis revealed that the hypothesized paths linking attitude, subjective norm, perceived behavioral control, personal norm, and intention were supported; and personal norm significantly mediated the impact of subjective norm on intention. Moreover, our proposition that bicycle travelers’ decision-making process would differ based on their level of the attractiveness of unsustainable alternatives was generally supported. Overall, our results help us clearly understand the role of volitional and non-volitional processes, personal norm, past behavior, and the attractiveness of unsustainable alternatives in explaining the intention formation of bike traveling.     

Cultural Differences in Online Community Motivations: Exploring Korean Automobile Online Brand Communities (KAOBCs) and American Automobile Online Brand Communities (AAOBCs)

To gain a better understanding of online brand communities, this study has examined why people joined in online brand communities and whether there were some differences in the motivations of Internet users based on different cultures. Open-ended questions were asked to the community members from both South Korean Automobile Online Brand Communities (KAOBC) and American Automobile Online Brand Communities (AAOBC) in the first stage and then generated and utilized an online survey for the study. The study found that KAOBC members tended to have a stronger social network, business, and communication motivations than AAOBC members. As a primary motivation, information seeking is the strongest motivation for members of both KAOBC and AAOBC. They had a similar level of information motivation.

A composite measure of performance–expectation and performance-only measures

Performance–expectation measures and performance-only measures of service quality have been widely used in the literature. However, either of the two measures is not sufficient to explain customers’ evaluation of service quality and satisfaction. Their assumptions are too restrictive to explain the evaluation processes. From an analytic perspective, this paper derives a composite measure integrating both measures for service quality. The previous measures are nested in the composite measure. Due to this feature, the composite measure is more flexible than the previous measures. It can account for conflicting theories and empirical findings supporting each of the two measures. Furthermore, the composite measure allows us to interpret the link between service quality and customer satisfaction more intuitively.     

Seemingly inconsistent analyst revisions

In about 20%–30% of cases where an analyst revises two outputs (namely, earnings estimates, target prices, or stock recommendations) simultaneously, the two estimates are revised in opposite directions. Existing literature notes that these inconsistent outputs are widespread, and concludes that they are lower-quality, driven by strategic bias, and are viewed as less valid by investors. We find that these characterizations are generally inaccurate. Apparent inconsistency is largely driven by accounting and economic factors, with only limited evidence that investment banking-related conflicts play a role. Moreover, inconsistent outputs are neither less accurate than consistent outputs nor do they resolve less investor uncertainty upon their release. Overall, our results suggest that researchers should be cautious in interpreting the correlation between analyst outputs as a measure of bias or quality, and in using a single analyst output as a proxy for an analyst's overall views.

Systemic risk and dynamics of contagion: a duplex inter-bank network

This paper constructs a duplex banking network formed by credit relationships and information interaction via the banks’ balance sheet to model the structure of systemic risk and investigate the dynamic mechanism of contagion in terms of default and liquidity infection along with the factors that affect the extent of the contagion. We systematically explain the role that duplex banking networks play in different aspects of risk contagion. Through theoretical analysis and simulations, we conclude that asymmetric information interaction would increase the inflexibility of the system, which leads to liquidity shortage and possibly the collapse of the whole market. The weakness of systemic risk in the interior of the complex banking system can be characterized by the partial discount factor using illiquid assets in the information network. By improving the connectedness of the information network of the duplex networks, the spread of contagion can be partially slowed.     

食物消费结构升级对农业碳排放的动态影响机制研究

[目的]探寻主要食物消费结构与农业碳排放之间的动态关联机制。[方法]基于1990—2015年面板数据,通过VAR模型进行研究。[结果]结果显示食物消费结构升级与农业碳排放确实有着一定的关联性,且存在一定的滞后性,但其影响程度和方向因食物种类而异。[结论](1)从影响方向看,农业碳排放对肉禽类、奶类等动物性食物消费和粮食、蔬菜、食用植物油等植物性食物消费变动的冲击响应方向基本相反,这主要是由动物性食物和植物性食物的替代性导致;农业碳排放对食物消费变化冲击的响应方向呈正负交替变化,且随着时间的推移而趋于平缓,主要是由于农产品供求的收敛型"蛛网"变动特点引起。(2)从响应时间看,农业碳排放变动对植物性食物消费冲击响应更为迅速,主要是由于动物类食物调整生产周期明显长于植物类食物产品;以植物性食物消费代替动物性食物消费的方式在短期内(3～4年以内)确实可以一定程度上降低碳排放,但是长期看来效果并不明显;所有食物消费变动对农业碳排放的冲击效应在8～9期以后均逐渐消失,说明食物消费结构的变动对农业碳排放的影响持久,农业碳减排任务不可能在短期内一蹴而就,而需要长期而持续的努力。(3)从影响程度看,方差分解结果表明,对农业碳排放变动的影响贡献最大的是其自身,说明农业碳排放基数庞大,减排工作任务艰巨,尽管肉禽类食物消费导致的碳排放量比重较大,但研究期间农业碳排放变动的并不是主要由这类食物消费的变化导致,而是由植物性食物消费变化导致。研究结果为在满足居民食物消费需求的前提下降低农业碳排放、发展低碳农业提供一定的依据。
