This doctoral thesis consists of three essays within the field of economics of information privacy examined through the lens of behavioral and experimental economics. Rapid development and expansion of Internet, mobile and network technologies in the last decades has provided multitudinous opportunities and benefits to both business and society proposing the customized services and personalized offers at a relatively low price and high speed. However, such innovations and progress have also created complex and hazardous issues. One of the main problems is related to the management of extensive flows of information, containing terabytes of personal data. Collection, storage, analysis, and sharing of this information imply risks and trigger users’ concerns that range from nearly harmless to significantly pernicious, including tracking of online behavior and location, intrusive or unsolicited marketing, price discrimination, surveillance, hacking attacks, fraud, and identity theft. Some users ignore these issues or at least do not take an action to protect their online privacy. Others try to limit their activity in Internet, which in turn may inhibit the online shopping acceptance. Yet another group of users gathers personal information protection, for example, by deploying the privacy-enhancing technologies, e.g., ad-blockers, e-mail encryption, etc. The ad-blockers sometimes reduce the revenue of online publishers, which provide the content to their users for free and do not receive the income from advertisers in case the user has blocked ads. The economics of privacy studies the trade-offs related to the positive and negative economic consequences of personal information use by data subjects and its protection by data holders and aims at balancing the interests of both parties optimizing the expected utilities of various stakeholders. As technology is penetrating every aspect of human life raising numerous privacy issues and affecting a large number of interested parties, including business, policy-makers, and legislative regulators, the outcome of this research is expected to have a great impact on individual economic markets, consumers, and society as a whole. The first essay provides an extensive literature review and combines the theoretical and empirical evidence on the impact of advertising in both traditional and digital media in order to gain the insights about the effects of ad-blocking privacy-enhancing technologies on consumers’ welfare. It first studies the views of the main schools of advertising, informative and persuasive. The informative school of advertising emphasizes the positive effects of advertising on sales,competition, product quality, and consumers’ utility and satisfaction by matching buyers to sellers, informing the potential customers about available goods and enhancing their informed purchasing decisions. In contrast, the advocates of persuasive school view advertising as a generator of irrational brand loyalty that distorts consumers’ preferences, inflates product prices, and creates entry barriers. I pay special attention to the targeted advertising, which is typically assumed to have a positive impact on consumers’ welfare if it does not cause the decrease of product quality and does not involve the extraction of consumers’ surplus through the exploitation of reservation price for discriminating activities. Moreover, the utility of personalized advertising appears to be a function of its accuracy: the more relevant is a targeted offer, the more valuable it is for the customer. I then review the effects of online advertising on the main stakeholders and users and show that the low cost of online advertising leads to excessive advertising volumes causing information overload, psychological discomfort and reactance, privacy concerns, decreased exploration activities and opinion diversity, and market inefficiency. Finally, as ad-blocking technologies filter advertising content and limit advertising exposure, I analyze the consequences of ad-blocking deployment through the lens of the models on advertising restrictions. The control of advertising volume and its partial restriction would benefit both consumers and businesses more than a complete ban of advertising. For example, advertising exposure caps, which limit the number of times that the same ad is to be shown to a particular user, general reduction of the advertising slots, control of the advertising quality standards, and limitation of tracking would result in a better market equilibrium than can offer an arms race of ad-blockers and anti-ad-blockers. Finally, I review the solutions alternative to the blocking of advertising content, which include selfregulation, non-intrusive ads programs, paywall, intention economy approach that promotes business models, in which user initiates the trade and not the marketer, and active social movements aimed at increasing social awareness and consumer education. The second essay describes a model of factors affecting Internet users’ perceptions of websites’ trustworthiness with respect to their privacy and the intentions to purchase from such websites. Using focus group method I calibrate a list of websites’ attributes that represent those factors. Then I run an online survey with 117 adult participants to validate the research model. I find that privacy (including awareness, information collection and control practices), security, and reputation (including background and feedback) have strong effect on trust and willingness to buy, while website quality plays a marginal role. Although generally trustworthiness perceptions and purchase intentions are positively correlated, in some cases participants are likely to purchase from the websites that they have judged as untrustworthy. I discuss how behavioral biases and decision-making heuristics may explain this discrepancy between perceptions and behavioral intentions. Finally, I analyze and suggest what factors, particular websites’ attributes, and individual characteristics have the strongest effect on hindering or advancing customers’ trust and willingness to buy. In the third essay I investigate the decision of experimental subjects to incur the risk of revealing personal information to other participants. I do so by using a novel method to generate personal information that reliably induces privacy concerns in the laboratory. I show that individual decisions to incur privacy risk are correlated with decisions to incur monetary risk. I find that partially depriving subjects of control over the revelation of their personal information does not lead them to lose interest in protecting it. I also find that making subjects think of privacy decisions after financial decisions reduces their aversion to privacy risk. Finally, surveyed attitude to privacy and explicit willingness to pay or to accept payments for personal information correlate with willingness to incur privacy risk. Having shown that privacy loss can be assimilated to a monetary loss, I compare decisions to incur risk in privacy lotteries with risk attitude in monetary lotteries to derive estimates of the implicit monetary value of privacy. The average implicit monetary value of privacy is about equal to the average willingness to pay to protect private information, but the two measures do not correlate at the individual level. I conclude by underlining the need to know individual attitudes to risk to properly evaluate individual attitudes to privacy as such. В целом, с развитием Интернета и распространением компьютерных технологий и различных устройств, типа ноутбука, планшета, мобильного телефона, умных часов, и т.д., остро встал вопрос, связанный с защитой конфиденциальности персональных данных. Компании собирают террабайты такой информации ежедневно. Часто ее анализ ведет к положительным эффектам - выявление побочных действий медикаментов, улучшение транспортной инфраструктуры, оптимизация энергопотребления, и т.д. Но еще чаще такая информация используется для маркетинга, нежелательной рекламы, фишинга, мошенничества. По опросам, люди переживают за свои личные данные, но на деле прилагают мало усилий для их защиты. Социальные сети нормализуют и продвигают идею делиться такой информацией как можно больше. Законодательная система старается решить проблему, но пока отстает от скорости развития технологий. Потому что медленна и не гибка. И потому что обычно законы отличаются в разных странах, в то время, как Интернет не знает границ, и информация постоянно путешествует по всему миру, и не понятно какая юрисдикция должна ее контролировать. Сами люди - существа с ограниченной рациональностью. Поэтому взваливать всю ответственность по защите персональных данных на их плечи было бы безответственно. И вот здесь-то поведенческая экономика и пытается вмешаться, чтобы выявить когнитивные и психологические капканы, на которые попадается процесс принятия решений, чтобы скорректировать систему и помочь пользователям делать более осознанные решения в целом. В частности моя работа изучает, какие факторы и аспекты сайтов влияют на мнение пользователей по поводу того, как этот сайт будет себя вести по отношению к персональным данных их пользователей. И как это мнение о "честности" или уровне доверия влияет на желание совершить покупку на этом сайте. И почему иногда люди не доверяют сайту, но все равно готовы на нем купить что-то. Другая глава предлагает инновационный метод измерения уровня толерантности к риску раскрытия конфиденциальных персональных данных экспериментальным путем. И как потом из этих решений отделить уровень толерантности к риску от ценности самой информации для человека.
Плюс мы предлагаем в этой главе новый метод создания беспокойства о своих персональных данных в лабораторных условиях, который может использоваться в других экспериментах. А так же, мы эмпирическим путем валидируем предложенные методы в лабораторном эксперименте. Наконец третья глава рассматривает эффект блокировки онлайн рекламы на благосостояние пользователей с экономической точки зрения, и с психологической.
