Does telic/paratelic user mode matter on the effectiveness of interactive internet advertising? A reversal theory perspective

Drawing on reversal theory (Apter, 2007), the current research proposes that internet users' metamotivational state (telic vs. paratelic) determines advertising interactivity's effectiveness. An online field experiment involving 141 Facebook and Twitter users tests this proposition. Research findings support telic state consumers form more positive attitudes toward a low-level interactive ad, whereas paratelic state consumers form more positive attitudes toward a high-level interactive ad. Further, this research shows that an arousal seeking tendency mediates the metamotivational state's impact on ad attitude.     

Forecasting market turbulence using regime-switching models

We propose an early warning system to timely forecast turbulence in the US stock market. In a first step, a Markov-switching model with two regimes (a calm market and a turbulent market) is developed. Based on the time series of the monthly returns of the S&P 500 price index, the corresponding filtered probabilities are successively estimated. In a second step, the turbulent phase of the model is further specified to distinguish between bullish and bearish trends. For comparison only, a Markov-switching model with three states (a calm market, a turbulent bullish market, and a turbulent bearish market) is examined as well. In a third step, logistic regression models are employed to forecast the filtered probabilities provided by the Markov-switching models. A major advantage of the presented modeling framework is the timely identification of the factors driving the different phases of the capital market. In a fourth step, the early warning system is applied to an asset management case study. The results show that explicit consideration of the models’ signals yields better portfolio performance and lower portfolio risk compared to standard buy-and-hold and constant proportion portfolio insurance strategies.

引入外资对银行风险承担的影响研究——基于我国153家商业银行的经验证据

文章基于中国153家商业银行2001-2017年的非平衡面板数据,采用双重差分模型研究了引入外资对银行风险承担的影响.实证结果表明:引入外资降低了中国商业银行的风险承担,外资股东发挥了积极的外溢效应和监督作用;外资持股比例与中国商业银行风险承担之间呈非线性的U型关系;引入外资影响中国商业银行的商业模式,引入外资的银行的非利息收入占比下降、非存款类负债占比上升,收入结构注重稳健且融资结构得到优化.上述研究结论的政策启示为:积极学习境外金融机构的先进知识和技术,建立可持续发展的合作伙伴关系;高度重视金融稳定,对外资进入中国银行体系实行分类管理;适度稳妥地推进中国银行业对外开放,把握好金融开放与金融安全之间的战略平衡.     

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.     

UGC的表现形式对网络营销效果的影响研究——以微博为例

随着Web2.0的兴起,用户创作内容（UGC）的概念应运而生,迅速发展并逐渐成为供应商组织生产、商家营销宣传以及消费者购买产品的利器.本论文梳理了UGC相关研究的分类和趋势,并选择微博作为平台,采用情景实验法,探究UGC的表现形式（文本、图片、音视频）对网络营销效果的影响,在此基础上为企业进行更大范围的社会化媒体营销（如博客、SNS社区等）提供策略性建议与营销思路,有效提升UGC互动的效用,在理论和实际应用上都有着显著意义.     

人才培养目标与教学管理水平的关系整合——以高职土建类专业为例

On a general periodic preventive maintenance policy incorporating warranty contracts and system ageing losses

In this paper, a general periodic preventive maintenance (PM) policy for a repairable revenue-generating system is developed and studied. We define ‘ageing losses’ as the difference in revenues generated by an ideal system (no ageing) and a real system that ages over the same period of consideration. It is assumed that preventive maintenance slows the system deterioration process and therefore reduces ageing losses. The proposed model is general in the sense that (1) both the warranty contracts and system ageing losses are incorporated in the maintenance cost modeling and (2) the implementation of PM actions does not have to be strictly periodic. A cost model is developed for the buyer under two decision variables—the calendar time of the first PM and the degree of each PM. Numerical examples are then presented to show the effectiveness of the proposed model. Sensitivity analyses are further conducted to investigate the impact of model parameters on optimal solutions.
