The information quality and source credibility matter in customers’ evaluation toward food O2O commerce

This study examines customer’s decision making when purchasing food product through O2O commerce applying the elaboration likelihood model (ELM) and the technology acceptance model (TAM). Further, this research investigates which information processing path, central route (information quality) or peripheral route (source credibility), is related to purchase frequency. Results of the data analysis demonstrate (1) the positive relationship between information quality, perceived usefulness, and perceived ease of use; (2) the significant relationship between source credibility, perceived usefulness, and perceived ease of use; (3) the significant influence of perceived usefulness and perceived ease of use on customer trust; and (4) the significant relationships among customer trust, attitudes, and behavioral intentions. In addition, customers with high purchase frequency tend to process messages via the central route, while customers with low purchase frequency focus on the peripheral route. These findings provide theoretical and managerial implications that contribute to O2O commerce marketing.     

Differently motivated exchange traded fund trading activities and the volatility of the underlying index

This paper examines the correlations between two types of a market index's volatility and three trading motives of the index's exchange traded funds (ETFs). We find that ETF trading driven by belief dispersion is highly correlated with both the variance in efficient price innovations (VEPI) and the index's total volatility. Privately informed ETF trading is closely connected to the VEPI but not the total volatility, while liquidity ETF trading explains the total volatility but has little power in explaining the VEPI. Moreover, the leading ETF dominates smaller ETFs in explaining both types of volatility and often has more explanatory power than control variables.     

The voice of minority shareholders: Online voting and corporate social responsibility

In 2014, the Shenzhen Stock Exchange introduced “Rules for the Implementation of Online Voting” to standardize the implementation of online voting for its listed companies. Using this event as an exogenous shock, we design a difference-in-differences model to show that minority shareholders’ participation in online voting improves firms’ corporate social responsibility performance. We reveal that this improvement is achieved through minority shareholders’ positive influence on firms’ internal control and transparency and is more pronounced for private firms and firms with lower levels of profitability and less external monitoring. Accordingly, since the standardization of online voting, minority shareholders have played an important role in corporate governance and have a positive influence on firms’ sustainable development.     

Sequential optimization three-way decision model with information gain for credit default risk evaluation

To categorize credit applications into defaulters or non-defaulters, most credit evaluation models have employed binary classification methods based on default probabilities. However, while some loan applications can be directly accepted or rejected, there are others on which immediate accurate credit status decisions cannot be made using existing information. To resolve these issues, this study developed an optimized sequential three-way decision model. First, an information gain objective function was built for the three-way decision, after which a genetic algorithm (GA) was applied to determine the optimal decision thresholds. Then, appropriate accept or reject decisions for some applicants were made using basic credit information, with the remaining applicants, whose credit status was difficult to determine, being divided into a boundary region (BND). Supplementary information was then added to reevaluate the credit applicants in the BND, and a sequential optimization process was employed to ensure more accurate predictions. Therefore, the model’s predictive abilities were improved and the information acquisition costs controlled. The empirical results demonstrated that the proposed model was able to outperform other benchmarking credit models based on performance indicators.     

地理距离、契约设计与企业内部资本市场借贷风险防控——来自中国企业集团内部借贷交易的证据

地理因素对保持距离型市场交易的影响已被大量文献证实,但系统考察地理因素是否以及如何影响企业内部经济活动的研究仍十分匮乏。基于手工搜集整理的企业集团内部委托贷款这一独特数据,我们实证考察了地理距离对企业集团内部借贷契约设计的影响及相关的风险防控问题。实证结果显示,借贷距离越远,针对借款者的契约设计越严苛,不仅贷款者更可能要求借款者提供抵押担保,而且对资金用途施加限制的概率也大幅增加。进一步研究发现,与地理距离阻碍了信息搜集和监督的经济直觉一致,距离对企业内部借贷契约严苛性的推高作用会因为借贷双方之间的信息摩擦问题差异而改变。而且,基于借贷违约信息的检验结果表明,作为应对信息不对称的机制,动态调整契约严苛性这一精巧契约设计有效降低了企业内部贷款违约风险。本文不仅增进了对地理因素影响企业内部资本配置的认识,而且加深了对企业内部借贷契约设计的理解,从而对如何有效防控企业内部资本市场运作风险具有启示意义。

Optimal warranty arrangements for the design of accounting information systems

This paper investigates optimal price/warranty arrangements for the design of accounting information systems (AISs) when the user of the system has alternative sources of information. A mathematical model is developed that focuses on two systems design scenarios commonly encountered in practice: (1) enhancement and (2) replacement. In an enhancement scenario the AIS user hires the AIS designer to enhance the value of the current AIS by incorporating additional features into the original system. Systems replacement, on the other hand, implies that the designer produces a new system that makes the original system obsolete. Under a replacement system, a simple limited warranty implements the user's optimal decision rule so that no losses occur due to unobservability of the user's decision. For the enhanced AIS design however, the user's action may depend upon the signal from the user's preexisting AIS. Therefore, when the user's decision is not observable, the designer does not know if the user's decision is a result of the systems enhancement or a result of the original system. Due to incomplete contracts, a more complex and costly warranty arrangement is required. Hence, losses occur under enhancement AIS although quality can be maintained with a limited warranty. Since it is difficult to assess the quality of the information system prior to purchase, the potential for a market failure exists where high-quality systems are driven from the market by low quality systems. These findings show that a market failure can be prevented in the design of information systems through contractual warranty arrangements. These warranty arrangements, however, must be tailored to the specific design task.

Micro-foundations of market orientation: Influencing non-marketing managers' customer information processing

This study examines how organisational context influences search, integration, and use of customer information at the level of an individual manager. Drawing upon research on market orientation, market-information utilisation, organisational learning, and marketing organisation, a theoretical framework is set up and tested by using structural equation modelling and a dataset consisting of 228 manufacturing and R&D managers in large industrial firms. Results demonstrate that integration of customer information enhances use of information in decision making. Organisational context influences the use of customer information indirectly by affecting information search and integration. Resource inadequacy and physical distance from sales and marketing contact persons decrease information integration, whereas supervisor customer emphasis increases the search scope of information. Wide search scope of customer information increases information integration but has no direct impact on use.
