Prior research has shown that an individual's hormonal profile can influence the individual's social standing within a group. We introduce a different construct — a collective hormonal profile — which describes a group's hormonal make-up. We test whether a group's collective hormonal profile is related to its performance. Analysis of 370 individuals randomly assigned to work in 74 groups of three to six individuals revealed that group-level concentrations of testosterone and cortisol interact to predict a group's standing across groups.

The notion that effort and hard work yield desired outcomes is ingrained in many cultures and affects our thinking and behavior. However, could valuing effort complicate our lives? In the present article, the authors demonstrate that individuals with a stronger tendency to link effort with positive outcomes end up complicating what should be easy decisions. People distort their preferences and the information they search and recall in a manner that intensifies the choice conflict and decisional effort they experience before finalizing their choice.

The removal of “conservatism” as a qualitative characteristic from the Conceptual Framework of the IFRS has met with considerable resistance. This paper argues that conservatism has a role in accounting, but not as a qualitative characteristic. Rather, it serves as a defining principle for how accounting is to be done. It is thus central to resolving “recognition” and “measurement” issues in the Conceptual Framework, issues that determine what actually goes into the balance sheet and income statement but issues on which the Framework is particularly weak.

This research examines the relationship between desire for control and acceptance of new products. We hypothesize that desire for control — the need to personally control outcomes in one's life — acts as a barrier to new product acceptance. Three experiments provide support for this hypothesis. This effect holds when desire for control is high as a dispositional trait (Studies 1 and 3) and when it is situationally induced (Study 2). We also identify an intervention to increase new product acceptance based on the idea that new products threaten one's sense of control.

We address a critical question that many firms are facing today: Can customer data be stored and analyzed in an easy-to-manage and scalable manner without significantly compromising the inferences that can be made about the customers' transaction activity? We address this question in the context of customer-base analysis. A number of researchers have developed customer-base analysis models that perform very well given detailed individual-level data.

This paper investigates financial attention using novel panel data on daily investor online account logins. We find support for selective attention to portfolio information. Account logins fall by 9.5% after market declines. Investors also pay less attention when the VIX volatility index is high. The level of attention and the attention/return correlation are strongly related to investor demographics (gender, age) and financial position (wealth, holdings). Using a new statistical decomposition, we show how aggregate and individual household trading are related to investor attention.

Until fairly recently, the main approach to getting business to respond to climate change has been top-down efforts to regulate emissions and enact various forms of "carbon pricing." The aim of such efforts has been to make businesses "internalize" the costs associated with greenhouse gas (GHG) emissions. Governments are expected to set the environmental protection rules for companies in their respective countries, and markets are expected to adjust to the new regulations and carbon prices.

In this commentary, we reflect on several important issues and questions provoked by Murphy and Dweck's target article. First, we define a mindset as a frame of mind that affects the selection, encoding, and retrieval of information as well as the types of evaluations and responses an individual gives. As such, we suggest that while studying fixed versus growth mindsets is important, it is critical to explore and understand how a variety of mindsets affect consumer behavior, including regulatory focus, construal level, implementation versus deliberation, and power.

Regulatory changes are transforming the multitrillion dollar swaps market from a network of bilateral contracts to one in which swaps are cleared through central counterparties (CCPs). The stability of the new framework depends on the CCPs’ resilience. Margin requirements are a CCP’s first line of defense against the default of a counterparty. To capture liquidity costs at default, margin requirements need to increase superlinearly in position size.

Past research finds foreign visitors who accommodate their behavior to local norms to a moderate degree are appreciated more than those who accommodate little, but more extreme accommodation does not always evoke positive evaluations. To understand why high accommodation is appreciated more in some contexts than others, we investigate the role of diversity ideologies, proposing that differing responses follow from multiculturalism (that cultural traditions are unique, separate legacies) versus polyculturalism (that cultures are interacting systems which contribute to each other).

The present research examined whether possessing multiple social identities (i.e., groups relevant to one’s sense of self) is associated with creativity. In Study 1, the more identities individuals reported having, the more names they generated for a new commercial product (i.e., greater idea fluency). In Study 2, multiple identities were associated with greater fluency and originality (mediated by cognitive flexibility, but not by persistence). Study 3 validated these findings using a highly powered sample.

Norm violations engender both negative reactions and perceptions of power from observers. We addressed this paradox by examining whether observers' tendency to grant power to norm followers versus norm violators is moderated by the observer's position in the hierarchy. Because norm violations threaten the status quo, we hypothesized that individuals higher in a hierarchy (high verticality) would be less likely to grant power to norm violators compared to individuals lower in the hierarchy (low verticality).

Following the financial crisis of 2008–2009, a large literature has emerged that attempts to quantify and measure systemic risk. In this paper we focus on some of the more popular systemic risk indicators from this literature and ask how well they work, in the following sense: At the aggregate level, what information above that which is readily observable in the market do we learn from these systemic risk indicators?

We study the impact of limited inventory on optimal sales-force compensation contracts. We adopt a principal-agent framework, characterized by limited liability and rent sharing with the agent. A commonly invoked assumption in the inventory management literature is that the demand distribution satisfies the increasing failure rate (IFR) property. Under this assumption, however, past research has established that a quota-bonus contract—a widely adopted sales-force compensation contract in the practice—cannot sustain in equilibrium.

In sponsored search advertising, advertisers bid to be displayed in response to a keyword search. The operational activities associated with participating in an auction, i.e., submitting the bid and the ad copy, customizing bids and ad copies based on various factors (such as the geographical region from which the query originated, the time of day and the season, the characteristics of the searcher), and continuously measuring outcomes, involve considerable effort. We call the costs that arise from such activities keyword management costs.

Reviewing a fascinating range of evidence, Y. Jenny Xiao, Geraldine Coppin, and Jay J. Van Bavel (this issue) propose reciprocal links between intergroup psychology and perception. In so doing they consolidate an emerging body which resurrects and refreshes the “New Look” stance that social needs and expectations have a top-down influence on perceptions, not only social perceptions but also perceptions of the physical world.

In a dynamic setting with demand following a random process, we ask how investment and operating decisions can be delegated to a manager with unknown time preferences. Only the manager observes the demand realization in each period and, therefore, has private information when choosing whether to acquire the productive asset and, subsequently, how to utilize it. We derive accrual accounting-based performance measures under which the manager will make the efficient decisions provided the investment date is exogenously given.

Buildings have a major impact on the environment through excessive use of resources, such as energy and water, and large carbon dioxide emissions. In this paper we revisit the study of Eichholtz et al. (2010) about the economics of environmentally sustainable buildings and estimate the effect of green building practices on market rents. For this, we use new matching methods that take advantage of the clustered structure of the buildings data.

This paper examines the contribution of out-of-town second-house buyers to mispricing in the housing market. We show that demand from out-of-town second-house buyers during the mid 2000s predicted not only house-price appreciation rates but also implied-to-actual-rent-ratio appreciation rates, a proxy for mispricing. We then apply a novel identification strategy to address the issue of reverse causality.

I review the changing advertising landscape and suggest that the definition of advertising has inherently changed. Using the current advertising context, I develop research questions that consumer behavior scholars are well poised to address. This research agenda is rooted in real-world observations about advertising and can help us develop new theories about when, how, and why advertising influences and persuades consumers. A recurring theme in this article is that consumers may be misled due to information overload from multiple channels and sources.

In contrast to decades of research reporting surprisingly weak relationships between consumption and happiness, recent findings suggest that money can indeed increase happiness if it is spent the "right way" (e.g., on experiences or on other people). Drawing on the concept of psychological fit, we extend this research by arguing that individual differences play a central role in determining the "right" type of spending to increase well-being.

The study of multicultural identity has gained prominence in recent decades and will be even more urgent as the mobility of individuals and social groups becomes the "new normal." This paper reviews the state-of-the-art theoretical advancements and empirical discoveries of multicultural identity processes at the intrapersonal, interpersonal, and collective (e.g., organizational, societal) levels. First, biculturalism has more benefits for individuals’ psychological and sociocultural adjustment than monoculturalism.

We develop a tractable incomplete-markets model with an earnings process Y subject to permanent shocks and borrowing constraints. Financial frictions cause the marginal (certainty equivalent) value of wealth W to be greater than unity and decrease with liquidity w=W/Y. Additionally, financial frictions cause consumption to decrease with this endogenously determined marginal value of liquidity. Risk aversion and the elasticity of inter-temporal substitution play very different roles on consumption and the dispersion of w.

When a proxy contest is looming, the rate at which CEOs exercise options to sell (hold) the resulting shares slows down by 80% (accelerates by 60%), consistent with their desire to maintain or strengthen voting rights when facing challenges. Such deviations are closely aligned with features unique to proxy contests, such as the record dates and nomination status, and are more pronounced when the private benefits are higher or when the voting rights are more crucial.

Delegation is a central feature of organizational design that theory suggests should be aligned with the intensity of incentives. We explore a specific form of delegation, namely price delegation, whereby firms allow sales people to offer a maximum discount from the list price to their customers. We develop a model of the price delegation decision based on information acquisition that relies on characteristics of our empirical context of industrial sales.

Consumers frequently evaluate their own traits before making consumption decisions (e.g., am I thin enough for skinny jeans?). The outcome of these self-evaluations depends on the standard consumers use and on whether they evaluate self in assimilation or contrast to that standard. Previous self-judgment research has focused on self-standards that arise from social aspects of the environment, including people and groups.

Firms often use both objective/verifiable and subjective/non-verifiable performance measures to provide employees with effort incentives. We study a principal/two-agent model in which an objective team-based performance measure and subjective individual performance measures are available for contracting. A problem with tying rewards to subjective measures is that the principal may have incentives to understate the realization of those measures in order to reduce compensation. We compare two mechanisms for overcoming this credibility problem: bonus pools and reputation.

This study examines the voting behavior of independent directors of public companies in China from 2004–2012. The unique data at the individual-director level overcome endogeneity in both board formation and proposal selection by allowing analysis based on within-board proposal variation. Career-conscious directors, measured by age and the director's reputation value, are more likely to dissent; dissension is eventually rewarded in the marketplace in the form of more outside directorships and a lower risk of regulatory sanctions.

An Expected Utility maximizer can be risk neutral over a set of non-degenerate multivariate distributions even though her NM (von Neumann Morgenstern) index is not linear. We provide necessary and sufficient conditions for an individual with a concave NM utility to exhibit risk neutral behavior and characterize the regions of the choice space over which risk neutrality is exhibited. The least concave decomposition of the NM index introduced by Debreu [3] plays an important role in our analysis as do the notions of minimum concavity points and minimum concavity directions.

This paper examines the effects of employer social responsibility on the wages workers demand through randomized field experiments in two online labor marketplaces. Workers were recruited for short-term jobs and I manipulated whether or not they received information about the employer's social responsibility. I then observed the payment workers were willing to accept for the job.

People choose where to live and how much to invest in housing. Traditionally, the first decision has been the domain of spatial economics, while the second has been analyzed in finance. Spatial asset pricing is an attempt to combine equilibrium concepts from both disciplines. In the finance context, we show how spatial decisions can be framed as an expanded portfolio problem. Within spatial economics, we identify the consequences of hedging motives for location decisions.

Three high-power studies (N = 3,000 total) demonstrated that asking participants to recall an experience as a manipulation can have unintended consequences. Participants who recalled preoccupying secrets made more extreme judgments of an external environment, supporting the notion that secrecy is burdensome. This influence was found, however, only among a subset of participants (i.e., participants who successfully recalled secrets that corresponded to their condition). We introduce the concept of manipulation correspondence to understand these patterns of results.

We show that venture capitalists' (VCs) on-site involvement with their portfolio companies leads to an increase in (1) innovation and (2) the likelihood of a successful exit. We rule out selection effects by exploiting an exogenous source of variation in VC involvement: the introduction of new airline routes that reduce VCs' travel times to their existing portfolio companies.

In the past two decades, pricing research has paid increasing attention to instances where a product's price is divided into a base price and one or more mandatory surcharges, a practice termed partitioned pricing. Recently, partitioned pricing strategies in the marketplace have become more pervasive and complex, raising concerns that consumers do not always fully attend to or process all price information, and underestimate total prices, which in turn influences their purchasing behavior.
