For decades, there has been broad consensus within antitrust, intellectual property, and consumer law scholarship that consumers make decisions in their own best interests by consciously weighting the market’s relative prices, quantities, and qualities against each other. That consensus is unraveling in light of novel findings from cognitive and social psychology that explain how individuals’ concepts of what they prefer drive the global economy. At the same time, producers nowadays no longer merely satisfy consumers’ needs but also communicate their values, identities, and aspirations through the sale and marketing of products. As part of the growing interest in observations such as these, a wealth of psychological studies challenge the fundamental teaching of economics that the interplay of demand and supply of goods in a free market economy provides us with material wealth. This book provides a normative defense of that assumption and a theoretical framework for understanding its contradictions. It argues that the erosion of consumer sovereignty through the ability of product manufacturers and sellers to systematically take advantage of individuals’ psychological weaknesses demands a twenty-first-century reconceptualization of the consumer and a modern account of how the law should regulate the digital economy. Such an account is justified to ensure a diverse marketplace in which consumers can influence how our societies are structured and arranged. By examining the role that market manipulation plays, it offers ingredients for a realistic descriptive and normative market regulatory theory that is aware of its political economy, its behavioral suppositions, and its distributional consequences.
Restoring Consumer Sovereignty: How Markets Manipulate Us and What the Law Can Do About It
Abstract. For decades, there has been broad consensus within antitrust, intellectual property, and consumer law scholarship that consumers make decisions i

Evolution of Consumption: A Psychological Ownership Framework
Technological innovations are creating new products, services, and markets that satisfy enduring consumer needs. These technological innovations create value for consumers and firms in many ways, but they also disrupt psychological ownership––the feeling that a thing is “MINE.” The authors describe two key dimensions of this technology-driven evolution of consumption pertaining to psychological ownership: (1) replacing legal ownership of private goods with legal access rights to goods and services owned and used by others and (2) replacing “solid” material goods with “liquid” experiential goods. They propose that these consumption changes can have three effects on psychological ownership: they can threaten it, cause it to transfer to other targets, and create new opportunities to preserve it. These changes and their effects are organized in a framework and examined across three macro trends in marketing: (1) growth of the sharing economy, (2) digitization of goods and services, and (3) expansion of personal data. This psychological ownership framework generates future research opportunities and actionable marketing strategies for firms aiming to preserve the positive consequences of psychological ownership and navigate cases for which it is a liability.

The Consumer in Physical Pain: Implications for the Pain-of-Paying and Pricing
AbstractOver one in five Americans suffer from chronic pain—a figure that does not include other, milder, transient types of pain. Thus, there is abundant work exploring the influence of physical pain on physical and psychological welfare. However, there is no work regarding how physical pain influences consumption decisions, which is important because people in physical pain still buy products and make purchases. Give that physical pain “demands” attention, we suggest that consumers in physical pain (vs. those who are not) feel the pain-of-paying less, thereby increasing their purchase intentions and willingness-to-pay for products. We find evidence for our hypothesis in four studies with field and lab assessments of physical pain. We discuss the contributions and limitations of our work. We also highlight several implications that concern pricing decisions for marketers.

Pain of Paying? — A Metaphor Gone Literal: Evidence from Neural and Behavioral Science
How do individuals consider the price of a good when making purchase decisions? Standard economic theories assume an analytical process: Individuals consider th
Behavioural economics, consumer behaviour and consumer policy: state of the art
Counter to the traditional assumption of neoclassical economics that individuals are rational Homo oeconomici that always seek to maximize their utility and follow their ‘true’ preferences, research in behavioural economics has demonstrated that people's judgements and decisions are often subject to systematic biases and heuristics, and are strongly dependent on the context of the decision. In this article, we briefly review the transition of research from neoclassical economics to behavioural economics, and discuss how the latter has influenced research in consumer behaviour and consumer policy. In particular, we discuss the impacts of key principles such as status quo bias, the endowment effect, mental accounting and the sunk-cost effect, other heuristics and biases related to availability, salience, the anchoring effect and simplicity rules, as well as the effects of other supposedly irrelevant factors such as music, temperature and physical markers on consumers’ decisions. These principles not only add significantly to research on consumer behaviour – they also offer readily available practical implications for consumer policy to nudge behaviour in beneficial directions in consumption domains including financial decision making, product choice, healthy eating and sustainable consumption.

Affording Disposal Control: The Effect of Circular Take-Back Programs on Psychological Ownership and Valuation
A circular economy is a “closed-loop” system designed so that products flow back into the production cycle after use. With many companies implementing take-back programs as part of their sustainability strategy, a fundamental shift in consumption has occurred, with consumers considering disposal during and even before purchase decision making. Eight experiments reveal that consumers indicate a greater willingness to pay for circular program products. An increase in psychological ownership underlies the difference in product valuation. Specifically, the additional disposal control uniquely afforded by circular products increases the capacity of circular take-back program products to evoke psychological ownership. The process explanation is directly tested through mediation. Experimentally manipulating antecedents of psychological ownership (i.e., disposal control and psychological ownership) provides further support for the conceptual framework.

Tightwads and Spendthrifts
Abstract. Consumers often behave differently than they would ideally like to behave. We propose that an anticipatory pain of paying drives “tightwads” to s

How Artificial Intelligence Constrains the Human Experience
AbstractArtificial intelligence (AI) and related technologies are transforming many consumption activities, powering breakthroughs that expand the human experience by enhancing human capabilities, performance, and creativity. While this explains the consumer enthusiasm and rapid adoption of these technologies, AI systems can also have the opposite effect: reducing and constraining the range of experiences that are available to consumers. This article examines the mechanisms through which AI can constrain the human experience, considering individual, interpersonal, and societal processes. Our analysis uncovers a complex interplay between the advantages of AI and its inadvertent negative repercussions, which potentially restrict human autonomy, self-identity, relational dynamics, and social behavior. In this article, we propose three different mechanisms at the core of these constraining forces: parametric reductionism, agency transference, and regulated expression. Our exploration of these mechanisms highlights the risks connected to system design and points to questions and implications for future researchers and policymakers.

Time-inconsistent Preferences and Consumer Self-Control
Abstract Why do consumers sometimes act against their own better judgment, engaging in behavior that is often regretted after the fact and that would have been rejected with adequate forethought? More generally, how do consumers attempt to maintain self-control in the face of time-inconsistent preferences? This article addresses consumer impatience by developing a decision-theoretic model based on reference points. The model explains how and why consumers experience sudden increases in desire for a product, increases that can result in the temporary overriding of long-term preferences. Tactics that consumers use to control their own behavior are also discussed. Consumer self-control is framed as a struggle between two psychological forces, desire and willpower. Finally, two general classes of self-control strategies are described: those that directly reduce desire, and those that overcome desire through will power.

The attention market—and what is wrong with it
Attention is described as a “scarce commodity” that is traded in “a marketplace.” This, it is further claimed, contributes to a “widespread sense of attentional crisis.” But is there really an attention market, and if so, what, if anything, is wrong with it? We defend the claim that there are markets in attention. We provide an account of such attention markets and use that account to address what is morally wrong with them. Our account draws on knowledge of how attention works and what roles it plays in the mind. The attention market trades in an ability to influence our attention – somewhat (though not exactly) like the labor market trades in an ability to influence how we use our capacity for work. Specifically, the commodity it trades in is attentional landscaping potential, viz. the ability to systematically influence patterns of attention by changes to the sensory environment individuals are exposed to. Attention markets thus, we argue, commodify influence over a human capacity that plays a central role in shaping individual experience, agency, and belief formation. This feature of attention markets makes them ethically problematic. As markets in access to external influence, attention markets pose a special threat to individual autonomy and escape the classical liberal defense of free markets. Those who value autonomy should worry about the attention markets that exist today.

Malleable Mental Accounting: The Effect of Flexibility on the Justification of Attractive Spending and Consumption Decisions
Mental accounts are often characterized as self‐control devices that consumers employ to prevent excess spending and consumption. However, under certain conditions of ambiguity, the mental accounting process is malleable; that is, consumers have flexibility in assigning expenses to different mental accounts. We demonstrate how consumers flexibly classify expenses, or construct accounts, to justify spending. An expense that can be assigned to more than one account (i.e., an ambiguous expense) is more likely to be incurred than an unambiguous expense that is constrained either by existing budgets or by previously constructed accounts. We explore the justification processes that underlie these results and their implications for mental accounts as self‐control devices.

Unwillingness to pay for privacy: A field experiment
We measure willingness to pay for privacy in a field experiment. Participants bought at most one DVD from one of two competing online stores. One store consistently required more sensitive personal data than the other, but otherwise the stores were identical. In one treatment, DVDs were one Euro cheaper at the store requesting more personal information, and almost all buyers chose the cheaper store. Surprisingly, in the second treatment when prices were identical, participants bought from both shops equally often.
Consumers’ Mental Representation of Expenditures: Implications for Spending and Saving Decisions
People’s mental representation of expenditures is crucial to how they budget. We propose that much like how people represent natural kinds (e.g., animals and pl
Gift Cards and Mental Accounting: Green‐lighting Hedonic Spending
ABSTRACT In three studies, we examine the mental accounting rules that govern how gift cards are used. We predicted that their identity as gift cards would shift consumption from utilitarian to hedonic goods even in contexts where both types of goods are available and the consumer's needs are unchanged. In Study 1a, participants were asked to imagine that they had both a gift card and a specified amount of cash and needed to purchase both a hedonic item and a utilitarian item. When asked which currency they would use to buy which item, respondents were significantly more likely to say they would use the gift card to buy the hedonic item. Study 1b replicated this result and found that it was tied to participants' beliefs how different types of money should be used. In Study 2, we found that participants who were required to spend a certain amount of their compensation in a laboratory store spent more on hedonic goods if their payment was in the form of a gift card. In Study 3, we analyzed transactions at a campus bookstore and found that shoppers tended to spend disproportionately on hedonic goods when using their gift cards than when making credit card purchases. Taken together, these studies indicate that people tend to assign the monetary value of a gift card to a hedonic mental account and spend it accordingly. Copyright © 2014 John Wiley & Sons, Ltd.

Lower Artificial Intelligence Literacy Predicts Greater AI Receptivity
As artificial intelligence (AI) transforms society, understanding factors that influence AI receptivity is increasingly important. The current research investigates which types of consumers have greater AI receptivity. Contrary to expectations revealed in four surveys, cross-country data and six additional studies find that people with lower AI literacy are typically more receptive to AI. This lower literacy–greater receptivity link is not explained by differences in perceptions of AI's capability, ethicality, or feared impact on humanity. Instead, this link occurs because people with lower AI literacy are more likely to perceive AI as magical and experience feelings of awe in the face of AI's execution of tasks that seem to require uniquely human attributes. In line with this theorizing, the lower literacy–higher receptivity link is mediated by perceptions of AI as magical and is moderated among tasks not assumed to require distinctly human attributes. These findings suggest that companies may benefit from shifting their marketing efforts and product development toward consumers with lower AI literacy. In addition, efforts to demystify AI may inadvertently reduce its appeal.
