Abstract

Purpose

Online advertisement brings huge revenue to many websites. There are many types of online advertisement; this paper aims to focus on the online banner ads which are usually placed in a particular news website. The investigated news website adopts a pay-per-ad payment model, where the advertisers are charged when they rent a banner from the website during a particular period. In this payment model, the website needs to ensure that the ad pushed frequency of each ad on the banner is similar. Under such advertisement push rules, an ad-recommendation mechanism considering ad push fairness is required.

Design/methodology/approach

The authors proposed a novel ad recommendation method that considers both ad-push fairness and personal interests. The authors take every ad’s exposure time into consideration and investigate users’ three different usage experiences in the website to identify the main factors affecting the interests of users. Online ad recommendation is conducted on the investigated news website.

Findings

The results of the experiments show that the proposed approach performs better than the traditional approach. This method can not only enhance the average click rate of all ads in the website but also ensure reasonable fairness of exposure frequency of each ad. The online experiment results demonstrate the effectiveness of this approach.

Originality/value

Existing researches had not considered both the advertisement recommendation and ad-push fairness together. With the proposed novel ad recommendation model, the authors can improve the ad click-through rate of ads with reasonable push fairness. The website provider can thereby increase the commercial value of advertising and user satisfaction.

Abstract

Purpose

Providing online news recommendations to users has become an important trend for online media platforms, enabling them to attract more users. The purpose of this paper is to propose an online news recommendation system for recommending news articles to users when browsing news on online media platforms.

Design/methodology/approach

A Collaborative Semantic Topic Modeling (CSTM) method and an ensemble model (EM) are proposed to predict user preferences based on the combination of matrix factorization with articles’ semantic latent topics derived from word embedding and latent topic modeling. The proposed EM further integrates an online interest adjustment (OIA) mechanism to adjust users’ online recommendation lists based on their current news browsing.

Findings

This study evaluated the proposed approach using offline experiments, as well as an online evaluation on an existing online media platform. The evaluation shows that the proposed method can improve the recommendation quality and achieve better performance than other recommendation methods can. The online evaluation also shows that integrating the proposed method with OIA can improve the click-through rate for online news recommendation.

Originality/value

The novel CSTM and EM combined with OIA are proposed for news recommendation. The proposed novel recommendation system can improve the click-through rate of online news recommendations, thus increasing online media platforms’ commercial value.

Abstract

Purpose

The purpose of this paper is to examine how investors’ valuation of cash holdings is related to firm-level investment.

Design/methodology/approach

As prior studies note that holding excess cash serve as a driver to would be over-investing, and that over-investment imposes substantial agency costs on shareholders, the authors focus on the value implications of holding cash in the presence of over-investment from the perspective of shareholders.

Findings

By examining the publicly traded companies on Taiwan stock market, the authors uncover that cash is valued less in firms with over-investment than in those with under-investment and the magnitude of over-investment is negatively related to the marginal value of cash holdings (MVCH). It reveals that investment activities impact the value that shareholders place on cash holdings. Moreover, further tests indicate that higher block holdings and the presence of independent directors on boards can effectively mitigate the negative impact of over-investment on the MVCH.

Practical implications

This paper enhances the understanding of the valuation implications of cash reserves held by firms with over-investment and the effectiveness of governance structures in containing the detrimental effect of investment-related agency costs on the value of holding cash.

Originality/value

This paper provides pioneering evidence that outside investors discount cash assets in over-investing firms to reflect their expectations that they will not receive the full benefit of these assets; and this paper extends the literature on corporate governance by assessing the role of governance mechanisms in reversing the negative relation between over-investment and the MVCH.

Abstract

Purpose

The purpose of this paper is to examine how customer orientation affects frontline service workers’ deep acting and to what extent the effect is moderated by the severity of dysfunctional customer behavior (DCB). Service organizations usually want their employees to demonstrate sincere emotions during customer encounters.

Design/methodology/approach

The study employed a mixed method design using measured variables (e.g. customer orientation) and a scenario-based manipulated variable (i.e. DCB severity). Data from 237 service workers were used to investigate the theoretical model.

Findings

Results showed that perspective taking and emotional sensitivity mediate the positive effect of customer orientation on deep acting. Furthermore, the influence of emotional sensitivity on deep acting is positive when DCB is less severe, but becomes non-significant when DCB becomes severe.

Research limitations/implications

Because the DCB severity is manipulated as a single event, future research can examine its influence based on employees’ experiences. Also, future studies may investigate other mechanisms to explain customer orientation’s effects on deep acting.

Practical implications

This paper provides service organizations an understanding of the key roles of emotional sensitivity and perspective taking in driving deep acting as well as the importance of monitoring DCB severity.

Originality/value

The study is one of the first in marketing to examine the different influences of DCB severity on important employee outcomes. This study also identifies two important mediators to explain how customer orientation drives deep acting.

Abstract

Purpose

Dysfunctional customer behavior (DCB) is costly and problematic for organizations. This research seeks to understand how DCB spreads and how businesses can effectively deal with it through employee intervention.

Design/methodology/approach

This research conducted a survey study and an experimental study to examine the proposed model.

Findings

Through two studies, we discovered that when an employee intervenes to stop DCB and is perceived as having high coping ability, observing customers learn from the employee’s action, resulting in reduced empathy toward the dysfunctional customer and diminished intentions to engage in DCB. Conversely, if they perceive the employee as having low coping ability, the intervention backfires, enhancing the observers’ empathy toward the dysfunctional customer and consequently leading them to engage in more DCB.

Originality/value

This research unveils an additional mechanism that explains the spread of DCB. It also contributes to the employee intervention literature by shedding light on when employee intervention can backfire. Further, our application of social learning theory along with the person-situation interaction literature offers a fresh perspective in explaining service exchanges.

Abstract

Purpose – Audit quality is traditionally defined as the joint probability that an existing problem is discovered and reported by the auditor. This study examines whether and how audit quality is associated with related-party transactions and CEO duality. The first part (i.e., the ability to discover) is related to professional judgment, and the second part (i.e., report truthfully) is related to independence.

Methodology/Approach – Regression methods was used on archival data.

Findings – Our results reveal that for publicly held companies in environments with stronger capital market discipline, which causes greater reputation concerns and litigation risks, a CEO who is also the board chair does not hinder auditor independence. For privately held companies, however, such a CEO hinders auditor independence due to a lack of capital market discipline. The findings on related-party financing, on the other hand, are reversed. That is, in terms of information for an auditor, since the conflicts of interests are more severe in publicly held companies than in privately held companies, the relevance of related-party financing to a decision whether to issue a going-concern opinion is greater in publicly held companies.

Social implications – The empirical results of publicly held companies are useful for countries with better corporate governance, while those of privately held companies are helpful for countries with relatively weak corporate governance.

Originality/Value of paper – Because auditors performing audit services face different litigation risks and reputation concerns, the differences in our results between the two types of clients can have implications about the suitability of these types of companies in emerging markets.
