The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.

The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.

In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.

The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.

The purpose of this research is to disprove the common assumptions of research into privacy concerns from an adversarial paradigm, which does not work in the context of the internet. These assumptions usually claim that internet users who have higher privacy concerns will disclose less information, and that data subjects are always adversarial to data users without considering social contexts.

The study surveyed 400 respondents from China, The Netherlands, Taiwan and the USA. It examined not only their privacy concerns, but also their actual practices, in order to identify any similarities between concerns and practices.

This study proved that internet users' privacy concerns do not reflect their privacy practices and showed how social contexts (Web category) influence users' privacy practices. Respondents from China, The Netherlands, Taiwan and the USA perceive Website categories in different ways, reflecting the influences of political systems, cultural background and economic development.

This study maintains that future research on online privacy should take contexts or situations into account. To confirm this, additional research should be undertaken on how social contexts in other countries affect users' privacy concerns and practices. Investigators should also study what makes users more likely to disclose information.

This study suggests that legislation provides the basic protection, while self‐regulation supplies the detailed principles of online privacy. Privacy education teaches users how to create their “zone of privacy” and how to be responsible for their online practices, in order to build an abuse‐free information environment on the internet.

This study aims to investigate the antecedents of mobile Internet users’ perception of information sensitivity (PIS) and willingness to provide personal information (WTP). It provides insights about how these antecedents influence users’ perceived information sensitivity and willingness to provide.

An online survey of mobile Internet users was conducted in China, generating a total of 1,000 qualified responses for analysis.

Results reveal the differential effects of some major antecedents of mobile Internet users’ perceived information sensitivity and willingness to provide (individual disposition to value privacy, age, gender, app type and privacy concerns) and such impact vary across low-, medium- and high-privacy segments.

This study provides insights into the antecedents of mobile Internet users’ attitudes towards personal information privacy. It also extends the understanding of users’ perceived information sensitivity and willingness to provide such information comparatively among four countries.

Considering that users’ information privacy concerns may affect the development of e-commerce, the purpose of this paper is to explore what drives internet users’ willingness to provide personal information; further, the paper examines how extrinsic rewards moderate the relationship between users’ information privacy concerns and willingness to provide personal information.

Data collected from 345 valid internet users in the context of electronic commerce were analyzed using the partial least squares approach.

The result showed that agreeableness, risk-taking propensity and experience of privacy invasion were three main antecedents of information privacy concerns among the seven individual factors. Additionally, information privacy concerns did not significantly affect users’ willingness to provide personal information in the privacy calculation mechanism; however, extrinsic rewards directly affected users’ disclosure intention. The authors found that extrinsic rewards had not moderated the relationship between users’ information privacy concerns and their willingness to provide personal information.

This study is an exploratory effort to develop and validate a model for explaining why internet users were willing to provide personal information. The results of this study are helpful to researchers in developing theories of information privacy concerns and to practitioners in promoting internet users’ willingness to provide personal information in an e-commerce context.

This study attempts to carry out an approximation both to the conceptual delimitation and to the measuring of customer concern for privacy on the electronic market.

To complete the objective of this research, an overview of the literature is made in an attempt to summarise the main proposals as regards dimensions of the construct analysed. Furthermore, two studies were carried out with the aim of evaluating the instruments to measure concern for privacy on the internet and which support the conclusion concerning the construct's dimensionality, reached following the aforementioned literature overview.

From the main results reached, we can highlight that the concern for privacy on the internet construct has a structure consisting of two dimensions, which are confirmed through the scales evaluated for different contexts of use of the internet. These dimensions are: concern for control over the collecting of personal information, and its use on the electronic market.

The paper's main contributions are threefold: a conceptual revision of the construct; a proposal of the dimensions for the construct; and an evaluation of two scales to measure the construct in different situations.

The purpose of this paper is to examine whether the internet users' privacy concerns (concerns for information privacy, CFIP) and perceived privacy control (PPC) affect their willingness to use internet web places in order to transact. A theoretical model is introduced that describes how users' CFIP and PPC may affect their willingness to transact through web places when personal information must be disclosed in order to accomplish the transaction.

The research model is empirically tested using data collected with a survey that include items for each of the constructs of the model. The survey is administrated to 190 internet users and resulted in 142 usable responses through questionnaires. In order to test the hypotheses, multidimensional regression analysis is used.

The findings indicate that both users' CFIP and users' PPC (some dimensions of them) have direct impact not only to users' trust toward the web site as expected but also to the willingness to transact through the internet when personal information needs to be disclosed.

In this paper, an introductory analysis is conducted in order to preliminary test the validity and credibility of the research model. In this first approach, the multidimensional regression analysis is used. Currently, the paper deals with the use of structural equation modeling in order to better test the research model. The research could be conducted also online in order to investigate users' behavior under real circumstances.

The more users know about their personal information the less willing they are to make purchases through internet. Moreover, if web places improve their mechanisms and procedures that correct better the inaccuracies and the errors in the users' stored personal data then users' willingness to retrieve information from web sites improves too.

Existing studies constitute the basic theoretical framework but until now there is not a model that connects both users' CFIP and users' PPC with the willingness to transact through the internet and with users' trust upon the web sites.

It is a widely held belief that users make a rational cost-benefit decision when choosing whether to disclose information online. Yet, in the privacy context, the evidence is far from conclusive suggesting that strong and as-yet unmeasured influences on behaviour may exist. This paper aims to demonstrate one such link – the effect of internet addiction on information disclosure.

Data from 216 Web users was collected regarding their perceptions on privacy and information disclosure intentions as well as avoidance behaviour, an element of internet addiction. Using a research model based on the Privacy Calculus theory, structural equation modelling was applied to quantify the determinants of online disclosure under various conditions.

The authors show that not all aspects of privacy (a multi-dimensional construct) influence information disclosure. While concerns about data collection influence self-disclosure behaviour, the level of awareness about privacy does not. They next examine the impact of internet addiction on these relationships, finding that internet addiction weakens the influence of privacy concerns to the point of non-significance.

The authors highlight some of the influences of self-disclosure behaviour, showing that some but not all aspects of privacy are influential. They also demonstrate that there are powerful influences on user behaviour that have not been accounted for in prior work; internet addiction is one of these factors. This provides some of the first evidence of the potentially deleterious effect of internet addiction on the privacy calculus.

This study aims to analyze and synthesize literature on consumer privacy-related behavior and intelligent device-to-device interactions within the Internet of Things (IoT).

We conducted a systematic review using Elsevier’s Scopus database, focusing on studies published in English from 2000 to 2023. The review targeted articles within selected social sciences and business disciplines, specifically concerning consumer behavior in IoT contexts.

We categorized the privacy literature into three thematic clusters: legislation and policy, business implications and consumer behavior. Within the consumer behavior cluster, our analysis indicates a shift from general Internet and e-commerce privacy concerns prior to 2016, toward issues related to advertising and policy between 2017 and 2018, and increasingly toward pronounced concerns in technological systems, particularly IoT, from 2019 onwards. We identify eight distinct areas of privacy concern within IoT and propose a framework that links antecedents and privacy concerns to subsequent attitudes and behaviors. This framework highlights varying patterns of information disclosure and bridges theoretical constructs with empirical research in IoT privacy.

Originality lies in enhancing the Antecedents-Privacy Concerns-Outcomes (APCO) macro-model by integrating diverse theoretical perspectives on technological and individual-specific antecedents, alongside privacy concerns and beliefs. This comprehensive integration enriches the framework, enabling it to predict and categorize consumer behavior in IoT environments more effectively. The revised model provides a robust tool for understanding privacy-related behavior within the IoT, significantly enriching its theoretical relevance and practical applicability.

The purpose of this paper is to investigate the attitudes and influential factors of users’ knowledge and use of the tools designated for controlling and enhancing online privacy, which are referred to as online privacy literacy (OPL). Particularly, inspired by the protection motivation theory, a motivational factor is defined as comprising several variables which reflect users’ motivation to protect their online privacy.

To this end, a user study was conducted based on the quantitative method with the participation of 169 students from the Israeli academia who were administered closed-ended questionnaires.

Generally low to moderate levels of OPL were obtained. Interestingly, the multivariate linear regression analysis showed that motivational factors, such as users’ concern for personal information protection on the internet and users’ privacy self-efficacy and sense of anonymity when visiting a website, were among the strongest predictive factors of users’ OPL level.

This research has social implications that might contribute to an increase in the OPL among internet users.

The direct influence of the examined factors on users’ OPL was not previously discussed in the literature. As a result of the study, a comprehensive model of user online privacy behavior was constructed.

Privacy considerations have become a topic with increasing interest from academics, industry leaders and regulators. In response to consumers’ privacy concerns, Google announced in 2020 that Chrome would stop supporting third-party cookies in the near future. At the same time, advertising technology companies are developing alternative solutions for online targeting and consumer privacy controls. This paper aims to explore privacy considerations related to online tracking and targeting methods used for programmatic advertising (i.e. third-party cookies, Privacy Sandbox, Unified ID 2.0) for a variety of stakeholders: consumers, AdTech platforms, advertisers and publishers.

This study analyzes the topic of internet user privacy concerns, through a multi-pronged approach: industry conversations to collect information, a comprehensive review of trade publications and extensive empirical analysis. This study uses two methods to collect data on consumer preferences for privacy controls: a survey of a representative sample of US consumers and field data from conversations on web-forums created by tech professionals.

The results suggest that there are four main segments in the US internet user population. The first segment, consisting of 26% of internet users, is driven by a strong preference for relevant ads and includes consumers who accept the premises of both Privacy Sandbox and Unified ID (UID) 2.0. The second segment (26%) includes consumers who are ambivalent about both sets of premises. The third segment (34%) is driven by a need for relevant ads and a strong desire to prevent advertisers from aggressively collecting data, with consumers who accept the premises of Privacy Sandbox but reject the premises of UID 2.0. The fourth segment (15% of consumers) rejected both sets of premises about privacy control. Text analysis results suggest that the conversation around UID 2.0 is still nascent. Google Sandbox associations seem nominally positive, with sarcasm being an important factor in the sentiment analysis results.

The value of this paper lies in its multi-method examination of online privacy concerns in light of the recent regulatory legislation (i.e. General Data Protection Regulation and California Consumer Privacy Act) and changes for third-party cookies in browsers such as Firefox, Safari and Chrome. Two alternatives proposed to replace third-party cookies (Privacy Sandbox and Unified ID 2.0) are in the proposal and prototype stage. The elimination of third-party cookies will affect stakeholders, including different types of players in the AdTech industry and internet users. This paper analyzes how two alternative proposals for privacy control align with the interests of several stakeholders.
