Prior studies have focused primarily on the issue of consumers’ privacy concerns in personalized advertising, but little is known about the effect of transparency awareness using data collection notifications on consumers. This study focuses on the relationship between consumers’ perceptions of the AI algorithms underlying online behavioral advertising (OBA) and the advertising effects. Our research model indicates that displaying data collection notifications regarding OBA and personalized ads increases favorable perceptions of AI systems, such as transparency. Moreover, the model suggests that personalized ads induce higher perceived surveillance than non-personalized ads.

Covid-19 pandemic has significantly affected online advertising market. The pandemic has changed customers’ shopping behavior by decreasing customer traffic in offline businesses but increasing customers’ online activities that has led to growth of online shopping and advertising. While the outbreak of Covid-19 has sparked growth of online advertising in general, its impact on various industries may not be the same, given the differences in product characteristics and consumer behavior across different products and services. This paper aims to address this question by empirically examining how Covid-19 has affected online search advertising market. First, we examine how Covid-19 has affected the behavior of online users and advertisers, the main stakeholders in the search advertising market, in terms of user traffic and clicks and advertiser bids and payments. Second, we examine if the impacts of Covid-19 on behavior of online users and advertisers would be different in various industries.

The decision between standardization and localization (or adaptation) of advertising strategy is crucial for the performance of product/service in foreign markets. Since the online advertising media have diluted the physical boundaries between countries, decision making related to international advertising has focused more on message strategy rather than media strategy. In this paper, the authors utilize movie poster images as a typical example of online advertising of service business. Employing image deep learning approach, the researchers calculate the level of localization and its effect on the financial performance in a foreign market. This research will expand the academic discussion in international advertising strategy and movie marketing.

This study aims to address two important questions: will advertising on mobile short-form video apps jeopardize the value perception of luxury brands (RQ1), and if so, how will self-deprecating online reviews eliminate these negative effects (RQ2). An experimental design approach was employed to investigate the proposed research questions. Three experiments were conducted to test the hypotheses. SPSS was used for data analysis. The study 1 finds that compared with traditional media, advertising on mobile short-form video apps shortened the psychological distance between consumers and luxury, therefore has a more negative impact on consumers’ perception of luxury brands. The study 2 reveals that self-deprecating online reviews can eliminate the negative effects of advertising of luxury brands. On the basis of previous research, this paper proves the negative influence of social media on luxury brands in the scene of new social media-mobile short format video application. In addition, it also studies the moderating effect of online comments, especially self-deprecating comments, on consumers' perception of luxury brands. This study outlines theoretical contributions and practical implications for the luxury marketing management and made suggestions for future research in the field of luxury marketing in Social Media.

Online search advertising (aka, sponsored or paid search advertising) is a technology that any matched advertisement is displayed on Web pages as online users’ query results from search engines and Web portals (e.g., Google, Bing, Baidu, Naver, and Yahoo!). In specific, after online users type search keywords on the search box (at this stage, online users become searchers), search engines match users’ query texts to phrases included in search advertisement. Then, if an advertiser’s investment on her/his search advertisement is high enough, the advertisement is likely to be displayed on a search engine results (called “impression”) (Hanson and Kalyanam 2007; Jansen et al. 2009; Jansen and Clark 2017; Moore, Stammerjohan, and Coulter 2005). Once a searcher clicks a displayed advertisement and arrives on the advertiser’s landing page, s/he becomes a visitor by clicking the impression. As benefits of utilizing search keywords, online search advertising can reduce search costs and increase information accessibility by potential customers. In addition, because online search advertising provides relevant search results based on the users’ own queries, it is considered less intrusive than banner advertisement and widely used by many marketers (Ghose and Yang 2009; Johnson, Bruner, and Kumar 2006; Quinton and Khan 2009; Rangaswamy, Giles, and Seres 2009; Yang and Ghose 2010).

INTRODUCTION Online marketing has grown rapidly over the past years and has become a key component when making marketing mix decisions. Over 2014, internet advertising revenues in the U.S. increased 16% from the previous year to a total of $49.5 billion (IAB 2015). In addition, according to Online Publisher Association, video advertisements have reached the majority of the Internet users (66%), and have resulted in an action from almost half of the users. The significant business opportunities provided by the online environment are reflected as the increasing amount of attention for online advertising in academic research (Mei et al. 2008). It is yet to be researched how online videos and the accompanied online video advertisements interact and how advertisement customization can play a role to possibly optimize user experience and therefore the effectiveness of online video advertisements. Particularly, congruity forms a key opportunity for customization in embedded online video advertising. Congruity is defined as consistency between the ad and video or the advertised product and video (Moore et al. 2005). Evidences in extent literature have shown the positive effects of congruity on, for example, the processing fluency of the ad, the consumer attitudes towards the ad and the persuasiveness of the ad (Moore et al. 2005). However, in the context of online video advertising, limited research has been conducted on this topic. The main goal of this research is to explore the effect of online video advertising congruity on consumer attitudes towards the online video, advertisement and advertised product. Therefore, this research attempts to examine the information processing of a consumer and how congruity acts in this process to affect consumer's preferences. Due to the nature of this research question, an online experiment is used to test the hypothesized relationships of the conceptual model. The collected data in this study were examined using partial least squares (PLS). CONGRUITY AND PROCESSING FLUENCY Congruity can be defined in terms of similarity. The perceived similarity between two given stimuli of equal importance, determines their congruity (Rokeach & Rothman, 1965). Extensive research has been conducted on the effects of congruity in advertising. For example, studies have focused on congruity between involvement types of ads and TV programs (Sharma, 2000), viewer's mood-ad content congruity (Kamins, Marks, & Skinner, 1991), and program context- advertised product congruity (De Pelsmacker, Geuens, & Anckaert, 2002). Previous research from (Moore, Stammerjohan, & Coulter, 2005) has shown that congruity has a positive effect on consumer attitudes. Research on online banner advertisements on websites has indicated that advertisements should be consistent with the website brand (Newman, Stem Jr, & Sprott, 2004). Appeal congruity can then be achieved when the appeal of the online video and the appeal of the embedded ad are similar: an emotional (affective) video paired with an emotional ad can be deemed congruent. Similarly, an informational ad will be more effective when embedded in an informational video. In this study, Ad-and-Video congruity represents such type of congruity. Based on extent research on processing fluency, it can be assumed that online video advertising congruity, either in terms of appeal or content, will result in more processing ease of the ad as the information provided by the video and ad is similar. The following hypotheses are formulated: Hypothesis 1: Congruity between the appeal of the online video and the appeal of the advertisement has a positive effect on processing fluency. Hypothesis 2: Congruity between content of the online video and the advertised product has a positive effect on processing fluency. We further propose that the above process is influenced by ad/video appeal or execution format (emotional vs. informational). An informational ad format is defined as an ad execution designed to appeal to the rationality of the receiver by using objective information describing a brand’s attributes or benefits, while an emotional ad format as an ad execution designed to appeal to the receiver’s emotions by using drama, mood, music and other emotion-eliciting strategies (Yoo & MacInnis, 2005). When an individual is watching an emotional ad or video, the possible effect of Ad-video or Product-video congruity on a consumer's processing fluency will be attenuated. The following hypotheses are formulated: Hypothesis 3a: Congruity between the appeal of online video and the appeal of embedded advertisement has a stronger effect on processing fluency for informational appeals than for emotional appeals. Hypothesis 3b: Congruity between content of the online video and the advertised product has a stronger effect on processing fluency for informational contents than for emotional contents. Involvement and processing fluency With regards to online advertising, research has shown that the degree to which a consumer is involved with the topic of a website also affects the processing of online advertising. It can be argued that when an individual is not involved in watching an online video, its effect on a consumer's processing fluency will be absent. On the other hand, when a consumer is highly involved in watching an online video, it is more likely that the viewer experiences processing fluency. As a result, in this situation, involvement may actually affect processing fluency of the viewer. Based on these findings, the following hypothesis is formulated: Hypothesis 4: Involvement has a positive effect on the processing fluency of consumers. Post-viewing attitudes Research has also indicated the mediating role of an individual’s affective response from processing fluency to its evaluation (Winkielman & Cacioppo, 2001). A viewer of an online video is shown an ad that has the same appeal as the video, making it rather easy to process. The viewer appreciates this as it takes less effort to view the ad and to relate to advertised product to the content of the video and the viewer's interests. As a result the viewer is more likely to generate a positive attitude towards the ad, the advertised product and the video. The insights lead to the formulation of the following three hypotheses: Hypothesis 5: Processing fluency has a positive effect on the attitude towards the online video. Hypothesis 6: Processing fluency has a positive effect on the attitude towards the advertisement. Hypothesis 7: Processing fluency has a positive effect on the attitude towards the advertised product. Figure 1 shows the conceptual model, which summarises the hypothesized relationships. <Insert Figure 1 about here> METHODOLOGY We conducted an experiment in the form of a 2 (type of appeal: informational vs. emotional) × 2 (Ad-Video congruity: congruent vs. incongruent) × 2 (Product-Video congruity: congruent vs. incongruent) full-factorial between-subject design. Video and advertisement appeal are each measured by the three items derived from the study by Moore et al. (1995) on the individual difference in response to advertising appeal. Processing fluency is measured by two items of the study by Lee and Aker (2004). Three items of the study from Zaichowsky (1985) are used to measure the involvement of the participants. The three items related to the attitude towards the video, advertisement and product are derived from the respective studies from Russell et al. (2004) and Kozup, Creyer and Burton (2003). Returned questionnaires numbered 276 responses with 24 incomplete data, resulting in 252 valid responses for data analysis. The collected data in this study were analyzed using partial least squares (PLS). Measurement model A measurement model was used to evaluate reliability, convergent validity, and discriminate validity. A structural model was used to determine the significance and association of each hypothesized path, and the explained variance. Reliability was examined by composite reliability values above the 0.70 benchmark (Fornell and Larcker 1981). Results show all values above 0.70, indicating satisfactory reliability. Convergent validity was examined by all indicator loadings that were significant and exceeding 0.7 and average variance extracted (AVE) by each construct exceeding 0.50 (Fornell and Larcker 1981). Results shows all indicator loadings above 0.70 and all AVEs exceeding 0.50, indicating satisfactory convergent validity. Discriminant validity is demonstrated by the square root of the AVE for each construct exceeding the correlations between the constructs (Chin 1998). These results indicate that the proposed models have good reliability and validity. Structure model Figure 2 shows the standardized path coefficient, the significance of each hypothesized path and the variance explained (R²). H1 and H2 investigate the effect of Ad-Video congruity and Product-Video congruity on processing fluency. Results show that Product-Video congruity is positively related to processing fluency (β=0.115, t-value=2.131, p<0.05), supporting H2. However, the effect of Ad-Video congruity on processing fluency is not significant ((β=0.022, t-value=0.377, p>0.05). Thus, H1 is not supported. H3a and H3b examine the moderating effect of the type of appeal. The hypothesis testing of H3a and H3b is discussed under the multi-group analysis (PLS-MGA). H4 proposes that involvement has a positive effect on the processing fluency of consumers, which is supported by the results (β=0.399, tvalue= 6.778, p<0.05). H5, H6, and H7 investigate the effects of processing fluency on post-viewing attitudes. Processing fluency is positively related to attitude towards the video (β=0.192, t-value=2.838, p<0.05), advertisement (β=0.426, t-value=7.607, p<0.05) and the focal product (β=0.422, t-value=7.171, p<0.05). These results support H5, H6 and H7. <Insert Figure 2 about here> We hypothesize that the type of appeal (informational or emotional) moderates the effects of Ad-Video congruity and Product-Video congruity on processing fluency in H3a and H3b. Specifically, the effects on under informational appeal condition are stronger. To test for group differences, we applied a multi-group analysis (PLS-MGA) approach. The PLS-MGA results for both informational and emotional groups, show that that the positive effect of Ad-Video congruity on processing fluency is only significant for informational appeals (β=.150, t-value=1.99, p<.05) but not emotional appeal (β=-.010, t-value=.15, p>.05), supporting H3a. Similarly, results show that that the positive effects of Product-Video congruity on processing fluency is only significant for informational appeals (β=.170, t-value=2.27, p<.05) but not emotional appeal (β=.050, t-value=.57, p>.05), supporting H3b. CONCLUSION Results show that congruity is related to the improvement of processing fluency only for informational ads/videos. This finding provides some support to the processing fluency theory which holds that less discrepant information should result in a higher processing fluency and extends the existing literature by investigating the appeal/execution format as a boundary condition. Involvement itself has been found to be positively related to processing fluency. Thus, when a consumer is initially more involved in watching a video, the processing fluency increases. This is in line with previous research that proved that involvement positively affects the attention that is given to advertisements and ultimately also the attitude of consumers.

This study seeks to examine the effects of customer’s power motivation in the social media context, driven primarily by to extend the theory of how powerlessness induces compensatory consumption (Rucker and Galinsky, 2008). Power motivation refers to a chronic desire to strive and retain power (Maner, Gailliot, Butz, & Peruche, 2007). Given that positions of power are often associated with enjoyment of social and material rewards, naturally some individuals strive to achieve and retain positions of power as a satisfying goal in itself (Cassidy and Lynn, 1989). These ‘power-strivers’ are motivated to achieve status and superiority, and prone towards negative emotional states when confronted with situations that induce a state of powerlessness. The sense of inferiority have been shown to lead to greater desire for status-enhancing goods, such as luxury items with more prominently displayed brand names to restore their sense of wellbeing (Rucker and Galinsky, 2009). In the context of social media, research suggests that longterm exposure to upward social comparisons on social media resulted in lower levels of self-esteem (Vogel, Rose, Roberts, & Eckles, 2014). We argue that observing other people’s ‘highlight reel’ on social media may also negatively influence the consumers’ sense of power. Thus, these type of consumers are likely to be more receptive towards communications that advertise status-enhancing goods. However, this effect should be particularly pronounced in consumers who have high power motivation in the first place. Subsequently, our first proposition is that when exposed to negative social comparisons, power motivation would moderate the consumers’ sense of inferiority and lead to more positive attitude towards advertisements of luxury goods. Our second proposition points to mindfulness as a palliative to mitigate this sense of inferiority, since exercising mindfulness enables better self-regulation that contributes to behaviors and decisions that positive contribute towards one’s wellbeing (Brown and Ryan, 2003). Two experimental studies confirm our hypotheses that when exposed to upward social comparisons on social media, power-strivers exhibit more positive attitude towards advertisements of luxury goods, mediated by a sense of inferiority. In the second study we found that implicitly inducing mindfulness mitigates the effects of power motivation. This paper thus enriches the understanding of the role of consumers’ sense of power in the context of social media. Furthermore, we offer a balanced view that (1) unpacks how marketers could exploit social media features to induce desire for luxury goods but also (2) suggests ethical solutions that contributes to positive psychology literature in the context of social media usage.

Online advertisers use multiple channels to reach consumers on the Internet. However, little is known on the interplay between online advertising channels. To fill this gap, this study provides a comprehensive overview of interaction effects in online advertising for individual consumers, including not only site visits, but also exposures that do not directly lead to a click. Based on a large cookie-based individual-level data set the authors analyze interaction effects within and between channel groups on purchase behavior. By classifying online marketing channels along the dimensions of initiation locus and previous brand awareness, they find significant interactions between contacts within and across channel types. While clicks following contacts in customer-initiated channels that require brand awareness overall have a negative effect on purchase propensity, previous clicks in firm-initiated channels positively interact with clicks in customer-initiated channels. The results can help managers to coordinate marketing strategies, optimize campaigns, and develop individualized marketing and targeting approaches.

The paper examines the reaction of the Z-Vietnam generation to online TV advertising (TVC), which elements of online TV advertising has a positive influence, which factors do not affect or negatively affect their consumption decisions for the advertised goods. Data for the study was collected from 300 Vietnam’s Generation Z in Ho Chi Minh City through live interviews or questionnaires through Google Docs Forms, with over 30 questions. The six basic factors that influence the reactions of Generation Z consumers are information, entertainment, irritation, credibility, interaction, and advertising value. The research results show that, due to the influence of social media and generational characteristics, most consumers of the Generation Z in Vietnam have a favorable attitude towards online TV advertising, and they appreciate this form of advertising. Information element, irritation, credibility and entertainment have a strong and positive impact on TVC. The other two factors are advertising value and interaction, which does not significantly affect the reaction of this generation. This study needs to be checked and reviewed by subsequent studies on a larger scale and in a wider scope because the study only conducted random sampling on a small scale, did not meet the requirements for representation and generality.
