Joshua Lewis and Deborah Small (Under Review), Ineffective Altruism: Giving Less When Donations Do More Good.
Abstract: Despite well-meaning intentions, people rarely allocate their charitable donations in the most cost-effective way possible. The manner in which cost-effectiveness information is presented can be a contributing factor. In four studies (N = 2,725), when we inform participants of the cost of a unit of impact (e.g. the cost of a mosquito net), they perversely donate less when the cost is cheaper. This result arises because people want their donation to have a tangible impact, and when the cost of such an impact is lower, people can achieve it with a smaller donation. A remedy for this inefficiency is to express cost-effectiveness in terms of “units per dollar amount” (e.g. 5 nets provided per $10 donated) and leave the cost of providing one tangible item unstated, rendering it less salient as a target donation amount. Across Studies 2 and 3, we demonstrate both the inefficiency and the effectiveness of the remedy for incentive-compatible donations decisions about providing meals, oral rehydration therapy, deworming medication, and measles vaccines.
Abstract: When do people make optimistic forecasts about goal-directed behavior? In five studies, we examine how an individual’s recent pattern of behavior affects their predictions regarding the likelihood of sticking to their goal. Specifically, we show that even when the overall rate of behavior is identical, a recent streak of goal-consistent behavior increases the predicted likelihood that the individual will persist, compared to a variety of other patterns. This effect is due to a perceived higher level of commitment following a recent streak. In turn, people are less likely to recommend the use of a restrictive goal pursuit strategy, like a commitment device, after a streak because they believe that it is unnecessary. The effect is attenuated in the presence of other diagnostic cues of commitment (i.e., the individual has a high base rate of goal-consistent behavior) and for predictions regarding behaviors that do not require commitment to a goal. Together, these results demonstrate the significance of streaky behavior for judgment and prediction.
Jonathan Z. Berman and Deborah Small (2018), Discipline and desire: On the relative importance of willpower and purity in signaling virtue,.
Abstract: Consumers often use moral language to discuss behavior with little moral relevance. For instance, ordering fruit salad instead of chocolate cake for dessert is considered “virtuous” even though most people do not consider it a moral choice. We examine decisions between virtue and vice options and show that people judge virtuous behavior differently across intertemporal (present self/future self) and moral (self/other) decisions. We argue that for intertemporal decisions, self-control primarily determines judgments of virtue: a person who resists temptation is seen as more virtuous than someone who does not feel tempted by a vice. However, for moral decisions, purity is primary: a person who resists temptation is seen as less virtuous than someone who does not feel tempted by a vice. We further show that thinking about past failures of purity increases intentions to act morally, whereas thinking about past self-control failures increases intentions to help the future self.

Abstract: People often brag about, or advertise, their good deeds to others. Seven studies investigate how bragging about prosocial behavior affects perceived generosity. The authors propose that bragging conveys information about an actor’s good deeds, leading to an attribution of generosity. However, bragging also signals a selfish motivation (a desire for credit) that undermines the attribution of generosity. Thus, bragging has a positive effect when prosocial behavior is unknown because it informs others that an actor has behaved generously. However, bragging does not help—and often hurts—when prosocial behavior is already known, because it signals a selfish motive. Additionally, the authors demonstrate that conspicuous cause marketing products have effects akin to bragging by signaling an impure motive for doing good deeds. Finally, the authors argue that bragging about prosocial behavior is unique because it undermines the precise information that the braggart is trying to convey (generosity). In contrast, bragging about personal achievements does not affect perceptions of the focal trait conveyed in the brag. These findings underscore the strategic considerations inherent in signaling altruism.

Abstract: Theories that reject the existence of altruism presume that emotional benefits serve as ulterior motives for doing good deeds. These theories argue that even in the absence of material and reputational benefits, individuals reap utility from the feelings associated with doing good. In response to this normative view of altruism, this article examines the descriptive question of whether laypeople penalize emotional prosocial actors. Six studies find that emotion serves as a positive signal of moral character, despite the intrapsychic benefits associated with it. This is true when emotion motivates prosocial behavior (Studies 1, 2, 3, and 5) and when emotion is a positive outcome of prosocial behavior (i.e., “warm glow”; Studies 4, 5, and 6). Emotional actors are considered to be moral because people believe emotion provides an honest and direct signal that the actor feels a genuine concern for others. Consequently, prosocial actors who are motivated by the expectation of emotional rewards are judged differently than prosocial actors who are motivated by other benefits, such as reputational or material rewards (Study 6). These results suggest that laypeople do not view altruism as incompatible with all benefits to the self.
This course is concerned with how and why people behave as consumers. Its goals are to: (1) provide conceptual understanding of consumer behavior, (2) provide experience in the application of buyer behavior concepts to marketing management decisions and social policy decision-making; and (3) to develop analytical capability in using behavioral research.
Private and public sector firms increasingly use marketing strategies to engage their customers and stakeholders around social impact. To do so, managers need to understand how best to engage and influence customers to behave in ways that have positive social effects. This course focuses on the strategies for changing the behavior of a target segment of consumers on key issues in the public interest (e.g., health behaviors, energy efficiency, poverty reduction, fundraising for social causes). How managers partner with organizations (e.g., non-profits, government) to achieve social impact will also be explored.

The purpose of this course is to provide a solid foundation for critical thinking and research on the judgment, decision-making and choice aspects of consumer behavior. There is a focus on how people process information when making judgments and choices and how the processes of judgment and choice might be improved. Topics of discussion include rationality, judgment under uncertainty, judgment heuristics and biases, risk taking, dealing with conflicting values, framing effects, prospect theory, inter-temporal choice, preference formation, and the psychology of utility. The focus will be on the individual decision-maker, although the topics will also have some applicability to group and organizational decision-making and behavioral research methodologies.
The purpose of this course is to build off MKTG 950, "Judgment and Decision Making Perspectives on Consumer Behavior - Part A" with a more specialized focus that will vary from year to year. This course is intended for those interested in deepening their study of Judgment and Decision Making beyond the basics.
