This paper from Columbia Business School, “Meaning of Manual Labor Impedes Consumer Adoption of Autonomous Products,” explores marketing solutions to some consumers’ resistance towards autonomous products. The study was co-authored by Emanuel de Bellis of the University of St. Gallen, Gita Johar of Columbia Business School, and Nicola Poletti of Cada.
Co-authored by John B. Donaldson of Columbia Business School, “The Macroeconomics of Stakeholder Equilibria,” proposes a model for a purely private, mutually beneficial financial agreement between worker and firm that keeps decision-making in the hands of stockholders while improving the employment contract for employees.

All these activities help to facilitate and streamline faculty research, and that of the doctoral students working with them.
The current research demonstrates that authenticity is directly linked to morality. Across five experiments, we found that experiencing inauthenticity consistently led participants to feel more immoral and impure. This inauthenticity-feeling immoral link produced an increased desire to cleanse oneself and to engage in moral compensation by behaving prosocially. We established the role that impurity played in these effects through mediation and moderation.
Music has long been suggested to be a way to make people feel powerful. The current research investigated whether music can evoke a sense of power and produce power-related cognition and behavior. Initial pretests identified musical selections that generated subjective feelings of power. Experiment 1 found that music pretested to be powerful implicitly activated the construct of power in listeners. Experiments 2–4 demonstrated that power-inducing music produced three known important downstream consequences of power: abstract thinking, illusory control, and moving first.
At some point, every company makes a mistake that requires an apology — to an individual; a group of customers, employees, or business partners; or the public at large. And more often than not, companies and their leaders fail to apologize effectively, if at all, which can severely damage their reputations and their relationships with stakeholders. Companies need clearer guidelines for determining whether a mistake merits an apology and, when it does, for crafting and delivering an effective message.
Successful managers and leaders need to effectively navigate their organizational worlds, from motivating customers and employees to managing diversity to preventing and resolving conflicts. Perspective-taking is a psychological process that is particularly relevant to each of these activities. The current review critically examines perspective-taking research conducted by both management scholars and social psychologists and specifies perspective-taking's antecedents, consequences, mechanisms, and moderators, as well as identifies theoretical and/or empirical shortfalls.
The current research examined the relationship between hierarchy and vocal acoustic cues. Using Brunswik's lens model as a framework, we explored how hierarchical rank influences the acoustic properties of a speaker's voice and how these hierarchy-based acoustic cues affect perceivers' inferences of a speaker's rank. By using objective measurements of speakers' acoustic cues and controlling for baseline cue levels, we were able to precisely capture the relationship between acoustic cues and hierarchical rank, as well as the covariation among the cues.
Having a well-defined hierarchy can contribute to organizational effectiveness: it helps people know who does what, when and how, and promotes efficient interactions by setting clear expectations for the behaviors of people of different ranks. This is especially true when people feel under threat, helping to restore a sense of order and control. However, sometimes hierarchy can hurt as much as it helps. In complex, dynamic situations, leaders need access to the most complete and varied information to make the best decisions.
In the wake of recent revelations about US involvement in torture, and widespread and seemingly-growing support of torture in the US, we consider how people judge the value of information gained from informants under coercion. Drawing on past work on confirmation biases and moral judgments, we predicted, and found, that American torture supporters are more likely than opposers to see coerced information as relatively valuable and necessary in a scenario describing the foiling of an al-Qaeda terrorist attack.
This research explores vagal flexibility — dynamic modulation of cardiac vagal control — as an individual-level physiological index of social sensitivity. In 4 studies, we test the hypothesis that individuals with greater cardiac vagal flexibility, operationalized as higher cardiac vagal tone at rest and greater cardiac vagal withdrawal (indexed by a decrease in respiratory sinus arrhythmia) during cognitive or attentional demand, perceive social-emotional information more accurately and show greater sensitivity to their social context.
Little is known about how discrimination manifests before individuals formally apply to organizations or how it varies within and between organizations. We address this knowledge gap through an audit study in academia of over 6,500 professors at top U.S. universities drawn from 89 disciplines and 259 institutions. In our experiment, professors were contacted by fictional prospective students seeking to discuss research opportunities prior to applying to a doctoral program.
Can subsidies promote Pareto-optimum coordination? We found that partially subsidizing the cooperative actions for two out of six players in a laboratory coordination game usually produced better coordination and higher total social welfare with both deterministic and stochastic payoffs. Not only were the subsidized players more likely to cooperate (choose the Pareto-optimum action), but the unsubsidized players increased their expectations on how likely others would cooperate, and they cooperated more frequently themselves.
International business (IB) research has predominantly relied on value constructs to account for the influence of societal culture, notably Hofstede's cultural dimensions. While parsimonious, the value approach's assumptions about the consensus of values within nations, and the generality and stability of cultural patterns of behavior are increasingly challenged.
We investigate whether homeowners respond strategically to news of mortgage modification programs by defaulting on their mortgages. We exploit plausibly exogenous variation in modification policy induced by U.S. state government lawsuits against Countrywide Financial Corporation, which agreed to offer modifications to seriously delinquent borrowers with subprime mortgages throughout the country. Using a difference-in-difference framework, we find that Countrywide's relative delinquency rate increased more than ten percent per month immediately after the program's announcement.

Power transforms consumer behavior. This research introduces a critical theoretical moderator of power's effects by promoting the idea that power is accompanied by both an experience (how it feels to have or lack power) and expectations (schemas and scripts as to how those with or without power behave). In some cases, the psychological experience of power predisposes people to behave one way, whereas attention to the expectations of power suggests behaving in another way. As a consequence, power's effects for consumer behavior can hinge on consumers' focus.
Five studies examined the relationship between talent and team performance. Two survey studies found that people believe there is a linear and nearly monotonic relationship between talent and performance: Participants expected that more talent improves performance and that this relationship never turns negative. However, building off research on status conflicts, we predicted that talent facilitates performance — but only up to a point, after which the benefits of more talent decrease and eventually become detrimental as intrateam coordination suffers.
Five studies examined the effect of breadth and depth of foreign experiences on generalized trust. Study 1 found that the breadth (number of countries traveled) but not the depth (amount of time spent traveling) of foreign travel experiences predicted trust behavior in a decision-making game. Studies 2 and 3 established a causal effect on generalized trust by experimentally manipulating a focus on the breadth versus depth of foreign experiences. Study 4 used a longitudinal design to establish that broad foreign travel experiences increased generalized trust.
A longitudinal study found that the psychological approach individuals take when immersed in a general multicultural environment can predict subsequent career success. Using a culturally diverse sample, we found that "multicultural engagement" — the extent to which students adapted to and learned about new cultures — during a highly international 10-month master of business administration (MBA) program predicted the number of job offers students received after the program, even when controlling for important personality/demographic variables.
Advertising supported content sampling is ubiquitous in online markets for digital information goods. Yet, little is known about the profit impact of sampling when it serves the dual purpose of disclosing content quality and generating advertising revenue. This paper proposes an analytical framework to study the optimal content strategy for online publishers and shows how it is determined by characteristics of both the content market and the advertising market.
This essay in celebration of Grossman and Hart (1986) (GH) discusses how the introduction of incomplete contracts has fundamentally changed economists' perspectives on corporate finance and control. Before GH, the dominant theory in corporate finance was the tradeoff theory pitting the tax advantages of debt (relative to equity) against bankruptcy costs. After GH, this theory has been enriched by the introduction of control considerations and investor protection issues.
Numerous studies have found that perspective-taking reduces stereotyping and prejudice, but they have only involved negative stereotypes. Because target negativity has been empirically confounded with reduced stereotyping, the general effects of perspective-taking on stereotyping and prejudice are unclear.
A central decision faced by firms is whether to make intermediate components internally or to buy them from specialized producers. We argue that firms producing products for which rapid technological change is characteristic will benefit from outsourcing to avoid the risk of not recouping their sunk cost investments when new production technologies appear. This risk is exacerbated when firms produce for low volume internal use, and is mitigated for those firms which sell to larger markets.

Using panel data from a large hospital system, this paper presents estimates of the productivity effects of human capital in a team production environment. Proxying nurses' general human capital by education and their unit-specific human capital by experience on the nursing unit, we find that greater amounts of both types of human capital significantly improve patient outcomes.
This paper finds statistically and economically significant out-of-sample portfolio benefits for an investor who uses models of return predictability when forming optimal portfolios. The key is that investors must incorporate an ensemble of important features into their optimal portfolio problem, including time-varying volatility, and time-varying expected returns driven by improved predictors such as measures of yield that include share repurchase and issuance in addition to cash payouts. Moreover, investors need to account for estimation risk when forming optimal portfolios.
This paper focuses on add-on sales to determine both their value per se and their value as a reflexive measure of brand equity. Specifically, this paper examines the "accessory premium" for automobiles, i.e., accessories installed by dealers at the time of sale. Using J.D. Power Data, the authors find that higher add-on accessory sales accrue to higher equity brands which make accessory sales a potentially useful measure of brand equity (J. Marketing 67: 1?17, 2003). In addition, the authors examine how the revenue premium metric varies by age cohort.
Friendly gestures (e.g., smiles, flattery, favors) typically build trust and earn good will. However, we propose that people feel unsettled when enemies initiate friendly gestures. To resolve these sensemaking difficulties, people find order through superstitious reasoning about friendly enemies. Supporting this theorizing, friendly enemies created sensemaking difficulty, which in turn mediated people's tendencies to blame them for coincidental negative outcomes (Experiment 1).
The current research explores how awareness of shared attention influences attitude formation. We theorized that sharing the experience of an object with fellow group members would increase elaborative processing, which in turn would intensify the effects of participant mood on attitude formation. Four experiments found that observing the same object as similar others produced more positive ratings among those in a positive mood, but more negative ratings among those in a negative mood.
Power is a psychological accelerator, propelling people toward their goals; however, these goals are often egocentrically focused. Perspective-taking is a psychological steering wheel that helps people navigate their social worlds; however, perspective-taking needs a catalyst to be effective.
Maintaining auditor independence is vital to the auditing profession. This article argues that the auditor-client relationship exhibits special traits that make maintaining auditor independence easier than in other accountant-client relationships. In particular, the auditor-client relationship satisfies a one-sided separability condition, as the auditor is not involved in the structuring of transactions (unlike other accountants).
We study the optimal composition of corporate boards. Directors can be either monitoring or advisory types. Monitoring constrains the empire-building tendency of chief executive officers (CEOs). If shareholders control the board nomination process, a non-monotonic relation ensues between agency problems and board composition. To preempt CEO entrenchment, shareholders may assemble an adviser-heavy board. If a powerful CEO influences the nomination process, this may result in a more monitor-heavy board.
We examine changes in banks' market-to-book ratios over the last decade, focusing on the dramatic and persistent declines witnessed during the financial crisis. The extent of the decline and its persistence cannot be explained by the delayed recognition of losses on existing financial instruments. Rather, it is declines in the values of intangibles — including customer relationships and other intangibles related to business opportunities — along with unrecognized contingent obligations that account for most of the persistent decline in market-to-book ratios.

Despite the importance of self-awareness for managerial success, many organizational members hold overly optimistic views of their expertise and performance — a phenomenon particularly prevalent among those least skilled in a given domain. We examined whether this same pattern extends to appraisals of emotional intelligence (EI), a critical managerial competency. We also examined why this overoptimism tends to survive explicit feedback about performance. Across 3 studies involving professional students, we found that the least skilled had limited insight into deficits in their performance.
The idea that group contexts can intensify emotions is centuries old. Yet, evidence that speaks to how, or if, emotions become more intense in groups remains elusive. Here we examine the novel possibility that group attention — the experience of simultaneous coattention with one's group members — increases emotional intensity relative to attending alone, coattending with strangers, or attending nonsimultaneously with one's group members. In Study 1, scary advertisements felt scarier under group attention.
The seminal work by Grossmann and Hart (1986) made the study of firm boundaries susceptible to formal economic analysis, and illuminated an important role for markets in providing incentives. In this essay, I discuss some new directions that the literature has taken since. As a central challenge, I identify the need to provide a formal theory of the firm in which managerial direction and bureaucratic decision-making play a key role. Merging a number of existing incomplete contracting models, I propose two approaches with very different contracting assumptions.
With globalization, cross-cultural competence is increasingly important to effective policies in international relations, business, and even in our schools and communities. Can we assess the skills and attributes relevant to gaining proficiency in other cultures? What kinds of training can help people toward this goal? Evidence on the assessment question comes from surveys of immigrant acculturation and expatriate adjustment, investigating antecedents including personality, general intelligence (g), and social-cultural intelligence.
This special section is the result of an effort by several scholars to move marketing academic research toward greater practical relevance. This initiative, called Theory Practice in Marketing (TPM), started with a conference at Columbia Business School in 2011, and the five papers published in this special section were presented at the second TPM conference held at Harvard Business School in 2012.

Although a great deal of research has examined specific behaviors that positively affect leaders' negotiation processes and outcomes, there has been considerably less attention devoted to stable characteristics, psychological or physical, that might also influence outcomes at the bargaining table. In the current research, we identify a measureable physical trait — the facial width-to-height ratio — that predicts negotiation performance in men.
Aggregation, and minimizing associated information loss, is a pervasive theme in accounting. In contrast, this paper highlights some potential benefits of aggregation, using simple examples to illustrate ideas from a number of recent papers in a parsimonious manner. Aggregation rules can improve decision making because of their ability to convey appropriate information and because such rules may permit offsetting errors. Turning to control problems, aggregation has merit in the provision of both explicit and implicit incentives.
In this article, we review empirical research investigating the efficacy of perspective-taking — the active consideration of others' mental states and subjective experiences — as a strategy for navigating intergroup environments. We begin by describing some of the benefits accrued from perspective-taking: more favorable implicit and explicit intergroup evaluations, stronger approach-oriented action tendencies and positive non-verbal behaviors, increased intergroup helping, reduced reliance on stereotype-maintaining mental processes, and heightened recognition of intergroup disparities.
Do people know when they are seen as pressing too hard, yielding too readily, or having the right touch? And does awareness matter? We examined these questions in four studies. Study 1 used dyadic negotiations to reveal a modest link between targets' self-views and counterparts' views of targets' assertiveness, showing that those seen as under- and over-assertive were likely to see themselves as appropriately assertive.
The current research establishes a first-mover disadvantage in negotiation. We propose that making the first offer in a negotiation will backfire when the sender reveals private information that an astute recipient can leverage to his or her advantage. In two experiments, we manipulated whether the first offer was purely distributive or revealed that the sender's preferences were compatible with the recipient's preferences (i.e., the negotiators wanted the same outcome on an issue).
Recent findings of low societal consensus in cultural values suggest that our field’s dominant paradigm — culture as shared values — is a fallacy. The perennial persistence of this illusion may come from the fact that it appeals to the human brain’s hardwired capacity for essentialism. Evidence against value consensus, however, does not doom all shared-meaning models of culture (pace Schwartz, 2013).
Learning requires acquiring and using knowledge. How do individuals acquire knowledge of another culture? How do they use this knowledge in order to operate proficiently in a new cultural setting? What kinds of training would foster intercultural learning? These questions have been addressed in many literatures of applied and basic research, featuring disparate concepts, methods and measures. In this paper, we review the insights from these different literatures. We note parallels among findings of survey research on immigrants, expatriate managers, and exchange students.
We propose that the psychological states individuals bring into newly formed groups can produce meaningful differences in status attainment. Three experiments explored whether experimentally created approach-oriented mindsets affected status attainment in groups, both immediately and over time. We predicted that approach-oriented states would lead to greater status attainment by increasing proactive behavior.
Previous research suggests that there is a fundamental link between expansive body postures and feelings of power. The current research demonstrates that this link is not universal, but depends on people's cultural background (Western versus East Asian) and on the particular type of expansive posture enacted. Three types of expansive postures were examined in the present studies: the expansive-hands-spread-on-desk pose (Carney et al., 2010), the expansive-upright-sitting pose, and the expansive-feet-on-desk pose (Carney et al., 2010).
