Particle learning (PL) provides state filtering, sequential parameter learning and smoothing in a general class of state space models. Our approach extends existing particle methods by incorporating the estimation of static parameters via a fully-adapted filter that utilizes conditional sufficient statistics for parameters and/or states as particles. State smoothing in the presence of parameter uncertainty is also solved as a by-product of PL. In a number of examples, we show that PL outperforms existing particle filtering alternatives and proves to be a competitor to MCMC.
In contrast to the view that social perception has symmetric effects on judgments and behavior, the current research explored whether perspective-taking leads stereotypes to differentially affect judgments and behavior. Across three studies, perspective-takers consistently used stereotypes more in their own behavior while simultaneously using them less in their judgments of others. After writing about an African-American, perspective-taking tendencies were positively correlated with aggressive behavior but negatively correlated with judging others as aggressive.
Five studies explored whether power increases moral hypocrisy, a situation characterized by imposing strict moral standards on others but practicing less strict moral behavior oneself. In Experiment 1, compared to the powerless, the powerful condemned other people's cheating, while cheating more themselves. In Experiments 2–4, the powerful were more strict in judging others' moral transgressions but more lenient in judging their own transgressions.
The preferred risk habitat hypothesis, introduced here, is that individual investors select stocks whose volatilities are commensurate with their risk aversion. The data, 1995-2000 holdings of over 20,000 clients at a large German broker, are consistent with the predictions of the hypothesis: the portfolios contain highly similar stocks in terms of volatility, when stocks are sold they are replaced by stocks of similar volatilities, and the more risk averse customers indeed hold and trade into less volatile stocks.
During a conversation, it is common for a speaker to describe a third-party that the listener does not know. These professed impressions not only shape the listener's view of the third-party but also affect judgments of the speaker herself. We propose a previously unstudied consequence of professed impressions: judgments of the speaker's power. In two studies, we find that listeners ascribe more power to speakers who profess impressions focusing on a third-party's conscientiousness, compared to those focusing on agreeableness.
Active investors provide entrepreneurs with risk-sharing and value-adding effort, e.g., in form of advising, networking and monitoring. However, holdup problems may create a conflict between two key objectives for high-quality entrepreneurs: to elicit investor effort and to credibly signal their firm type by retaining shares. As a result, pooling of startup firms of different types may arise, in particular when investor effort is essential. More established firms, with access to multiple signals, can always realize both of these objectives.
The present research explores how people's place in a power hierarchy alters their representations of valued objects. The authors hypothesized that powerlessness produces an accentuation bias by altering the physical representation of monetary objects in a manner consistent with the size-to-value relationship. In the first three experiments, powerless participants, induced through episodic priming or role manipulations, systematically overestimated the size of objects associated with monetary value (i.e., quarters, poker chips) compared to powerful and baseline participants.
Power — asymmetric control over valued resources — is a fundamental dimension of social relations. Classical conceptualizations of power emphasize its conscious nature. In this review, we reveal how power often operates nonconsciously and identify the different methods and paradigms used to activate or create a psychological sense of power outside of conscious awareness.
Based on the symbolic association between physical and moral purity, we introduce a provocative possibility: clean smells might not only regulate physical cleanliness, but may also motivate virtuous behavior. Indeed, moral transgressions can engender literal feelings of dirtiness (Zhong & Liljenquist, 2006). Just as many symbolic associations are reciprocally related (Lakoff, 1987), such as coldness and loneliness (Zhong & Leonardelli, 2008) or darkness and depravity (Frank & Gilovich, 1988), morality and cleanliness may also be reciprocally linked.
Wal-Mart has increasingly become the target of protests over its scale, manifested as contention over specific expansions. Often, the protests are local and led by local organizations, and as a result, chains face uncertainty whether local activists will organize a protest. We suggest that chain stores respond to this uncertainty through a "test for protest" approach. They use low-cost probes that take the form of proposals to open a store.
Research suggests that living in and adapting to foreign cultures facilitates creativity. The current research investigated whether one aspect of the adaptation process — multicultural learning — is a critical component of increased creativity. Experiments 1-3 found that recalling a multicultural learning experience: (a) facilitates idea flexibility (e.g., the ability to solve problems in multiple ways), (b) increases awareness of underlying connections and associations, and (c) helps overcome functional fixedness.
Health is a major component of well-being and quality of life (QOL) and an increasingly costly one. We examine the role of employers for promoting QOL. A meta-analysis examines the impact of fifty well-being programs, which address six health issues and use seven marketing approaches. The analysis indicates that well-being programs and marketing approaches significantly improve employee health and depend on company size and employee gender. Results, based on sixty studies, show there is significant opportunity to efficiently tailor corporate health programs.
This article asserts that any theory or research on fads or fashions in science has to answer three questions clearly and unambiguously. What defines "science"? What defines a "scientific fad" or a "scientific fashion"? What might facilitate the occurrence of scientific fads or fashions so defined? To illustrate this argument, this article critically examines the answers to three questions suggested by Starbuck's article: [Starbuck, W. H. (2009)] The constant causes of never-ending faddishness in the behavioral and social sciences. Scandinavian Journal of Management].
In December 2004, the Financial Accounting Standards Board (FASB) mandated the use of a fair value-based measurement attribute to value employee stock options (ESOs) via Financial Accounting Standard (FAS) 123-R. In anticipation of FAS 123-R, between March 2004 and November 2005, several firms accelerated the vesting of ESOs to avoid recognizing existing unvested ESO grants at fair value in future financial statements.
The diffusion of an innovation is governed by, among other things, word of mouth. In social systems, growth processes are considered strongly influenced by people who have large number of ties to other people. In the social network literature, such people are called influentials, opinion leaders, mavens, or sometimes hubs. Furthermore, when the marketing literature addresses such people, the focus is typically not on how they influence the overall market but rather on either assessing their influence on people they are in direct contact with or identifying their characteristics.
This research investigates hypotheses about differences between Chinese and American managers in the configuration of trusting relationships within their professional networks. Consistent with hypotheses about Chinese familial collectivism, an egocentric network survey found that affect- and cognition-based trust were more intertwined for Chinese than for American managers. In addition, the effect of economic exchange on affect-based trust was more positive for Chinese than for Americans, whereas the effect of friendship was more positive for Americans than for Chinese.

Research across disciplines suggests that bad is stronger than good and that individuals punish deception more than they reward honesty. However, methodological issues in previous research limit the latter conclusion. Three experiments resolved these issues and consistently found the opposite pattern: Individuals rewarded honesty more frequently and intensely than they punished deception.
We propose that people protect the belief in a controlled, nonrandom world by imbuing their social, physical, and metaphysical environments with order and structure when their sense of personal control is threatened. We demonstrate that when personal control is threatened, people can preserve a sense of order by (a) perceiving patterns in noise or adhering to superstitions and conspiracies, (b) defending the legitimacy of the sociopolitical institutions that offer control, or (c) believing in an interventionist God.
The present work examines how experiencing high versus low power creates qualitatively distinct psychological motives that produce unique consumption patterns. Based on accumulating evidence that states of power increase focus on one's own internal desires, we propose that high power will lead to a greater preference for products that are viewed as offering utility (e.g., performance, quality) to the individual.
Reflecting on the past is often a critical ingredient for successful learning. The current research investigated how counterfactual thinking, reflecting on how prior experiences might have been different, motivates effective learning from these previous experiences. Specifically, we explored how the structure of counterfactual reflection — their additive ("If only I had") versus subtractive ("If only I had not") nature — influences performance in dyadic-level strategic interactions.
Despite abundant anecdotal evidence that creativity is associated with living in foreign countries, there is currently little empirical evidence for this relationship. Five studies employing a multimethod approach systematically explored the link between living abroad and creativity. Using both individual and dyadic creativity tasks, Studies 1 and 2 provided initial demonstrations that time spent living abroad (but not time spent traveling abroad) showed a positive relationship with creativity.
We investigate whether current mid-level and future entry-level managers subjectively value stock options and restricted stock consistent with economic theory. We also investigate whether managers' subjective valuations are sensitive to changes in key characteristics of these equity instruments. We believe our investigation is important for three reasons. First, in recent years firms have granted the vast majority of options to employees who are not senior-level executives.
For decades, goal setting has been promoted as a halcyon pill for improving employee motivation and performance in organizations. Advocates of goal setting argue that for goals to be successful, they should be specific and challenging, and countless studies find that specific, challenging goals motivate performance far better than "do your best" exhortations. The authors of this article, however, argue that it is often these same characteristics of goals that cause them to "go wild."
Stocks with recent past high idiosyncratic volatility have low future average returns around the world. Across 23 developed markets, the difference in average returns between the extreme quintile portfolios sorted on idiosyncratic volatility is -1:31% per month, after controlling for world market, size, and value factors. The effect is individually significant in each G7 country. In the United States, we rule out explanations based on trading frictions, information dissemination, and higher moments.
Accumulating evidence suggests that targets' displays of emotion shape perceivers' impression of those targets. Prior research has highlighted generalization effects, such as an angry display prompting an impression of hostility. In two studies, we went beyond generalization to examine the interaction of displays and behaviors, finding new evidence of augmenting effects (behavior-correspondent inferences are stronger when behavior is accompanied by positive affect) and discounting effects (such inferences are weaker when behavior is accompanied by negative affect).

Three experiments demonstrated that the experience of power leads to an illusion of personal control. Regardless of whether power was experientially primed (Experiments 1 and 3) or manipulated through roles (manager vs. subordinate; Experiment 2), it led to perceived control over outcomes that were beyond the reach of the power holder.
This monograph focuses on the use of incomplete contracting models to study transfer pricing. Intrafirm pricing mechanisms affect division managers' incentives to trade intermediate products and to undertake relationship-specific investments so as to increase the gains from trade. Letting managers negotiate over the transaction is known to cause holdup (underinvestment) problems. Yet, in the absence of external markets, negotiations frequently outperform cost-based mechanisms, because negotiations aggregate cost and revenue information more efficiently into prices.
This special issue was conceived as a way to highlight how social cognition researchers are using the paradigm of negotiations to ask and answer a range of important questions central to their core concerns: how do communication media affect social information processing; how do different roles affect preferred processing styles; how do goals and expectancies shape interactions and outcomes?
As the record of Fed interventions from December 2007 to December 2008 make abundantly clear, a foremost concern of monetary authorities in responding to the financial crisis has been to avoid a repeat of the great depression, and especially a repeat of the monetary contraction identified as the major cause of the 1930s depression.

We investigate how nonfinancial performance measures (NPMs) can be used to encourage cooperation across divisions. The implementation of a project often requires joint efforts by multiple divisions. However, privately informed division managers sometimes find it in their self-interest to forgo profitable joint projects or to underinvest in relationship-specific assets.
In this article, we define good scholarship, highlight our points of disagreement with Locke and Latham (2009), and call for further academic research to examine the full range of goal setting's effects. We reiterate our original claim that goal setting, like a potent medication, can produce both beneficial effects and systematic, negative outcomes, and as a result, it should be carefully prescribed and closely monitored.
This paper provides an optimal filtering methodology in discretely observed continuous-time jump-diffusion models. Although the filtering problem has received little attention, it is useful for estimating latent states, forecasting volatility and returns, computing model diagnostics such as likelihood ratios, and parameter estimation. Our approach combines time-discretization schemes with Monte Carlo methods. It is quite general, applying in nonlinear and multivariate jump-diffusion models and models with nonanalytic observation equations.
We investigate determinants of slave family discounts in the New Orleans slave market. We find large price discounts for families unrelated to scale effects, childcare costs, legal restrictions, or transport costs. We posit that because family members voluntarily cared for each other, sellers sometimes found it advantageous to keep families together (when families included needy or dependent members). Evidence from ship manifests carrying slaves for sale in New Orleans provides direct evidence for selectivity bias in explaining slave family discounts.
Past work on interpersonal assertiveness and organizational effectiveness paints a mixed picture: some research suggests a positive link, other work highlights negative effects. This article reviews recent research and an account that stems from a different perspective, looking at assertiveness as a factor in leadership shortcomings and failure. This approach suggests that interpersonal assertiveness is a major factor and has a curvilinear, inverted-U-shaped relationship with leadership effectiveness. I review evidence for this effect as well as social and instrumental outcome mediators.
A criticism of mechanism design theory is that the optimal mechanism designed for one environment can produce drastically different actions, outcomes, and payoffs in a second, even slightly different, environment. In this sense, the theoretically optimal mechanisms usually studied are not "robust." To study robust mechanisms while maintaining an expected utility maximization approach, we study a multiagent model in which the mechanism must be designed before the environment is as well understood as is usually assumed.
Past research has established a connection between regret (negative emotions connected to cognitions about how past actions might have achieved better outcomes) and both depression and anxiety. In the present research, the relations between regret, repetitive thought, depression, and anxiety were examined in a nationally representative telephone survey. Although both regret and repetitive thought were associated with general distress, only regret was associated with anhedonic depression and anxious arousal.
We document how starting prices differentially impact outcomes in negotiations and auctions. In negotiations (where the number of actors is often predetermined), starting prices drive cognitive processes, leading individuals to selectively focus on information consistent with, and make valuations similar to, the starting value. Thus, starting high will often lead to ending high in negotiations.
In our recent article (Leung, Maddux, Galinsky, & Chiu, April 2008), we presented evidence supporting the idea that multicultural experience can facilitate creativity. In a reply to that article, Rich (2009, this issue) has argued that our review, although timely and important, was somewhat limited in scope, focusing mostly on smaller forms of creativity ("little c": e.g., paper- and-pencil measures of creativity) as well as on larger forms of multicultural experience ("Big M": e.g., living in a foreign country).
Individuals often honor sunk costs by increasing their commitment to failing courses of action. Since this escalation of commitment is fueled by self-justification processes, a widely offered prescription for preventing escalation is to have separate individuals make the initial and subsequent resource allocation decisions. In contrast to this proposed remedy, four experiments explored whether a psychological connection between two decision-makers leads the second decision-maker to invest further in the failing program orchestrated by the initial decision-maker.
We present a novel role of affect in the expression of culture. Four experiments tested whether individuals' affective states moderate the expression of culturally normative cognitions and behaviors. We consistently found that value expressions, self-construals, and behaviors were less consistent with cultural norms when individuals were experiencing positive rather than negative affect. Positive affect allowed individuals to explore novel thoughts and behaviors that departed from cultural constraints, whereas negative affect bound people to cultural norms.
Previous research suggests that narrow identification with one's own racial group impedes coalition building among minorities. Consistent with this research, the 2008 Democratic primary was marked by racial differences in voting preferences: Black voters overwhelmingly preferred Barack Obama, a Black candidate, and Latinos and Asians largely favored Hillary Clinton, a White candidate. We investigated one approach to overcoming this divide: highlighting one's negational identity.
Much of the puzzle of underissuance of national bank notes can be resolved for the period 1880–1900 (the period when detailed, bank-level data are available) by disaggregating, taking account of regulatory limits, and considering differences in banks' opportunity costs cross-sectionally and over time. Banks with poor lending opportunities issued more, within regulatory limits. Banks tended to issue more when bond yields (the backing for notes) were high relative to lending opportunities.
Drawing on the motivated cognition literature, we examine how self-affirmation processes influence self-justification needs and escalation decisions. Study 1 found that individuals with a larger pool of affirmational resources (high self-esteem) reduced their escalation compared to those with fewer affirmational resources (low self-esteem). Study 2 extended these findings by demonstrating that individuals also de-escalated their commitments when they were provided an opportunity to affirm on an important value.
Three experiments examine how power affects consumers' spending propensities. By integrating literatures suggesting that (a) powerlessness is aversive, (b) status is one basis of power, and (c) products can signal status, the authors argue that low power fosters a desire to acquire products associated with status to compensate for lacking power. Supporting this compensatory hypothesis, results show that low power increased consumers' willingness to pay for auction items and consumers' reservation prices in negotiations but only when products were status related.
We investigate the effects of babyfaceness on the trustworthiness and judgments of a company's chief executive officer in a public relations crisis. Experiment 1 demonstrates boundary conditions for the babyfaceness-honesty trait inference and its influence on company evaluations. Experiment 2 shows that trait inferences of honesty are drawn spontaneously but are corrected in the presence of situational evidence (a severe crisis) if cognitive resources are available.
Individuals define themselves, at times, as who they are (e.g., a psychologist) and, at other times, as who they are not (e.g., not an economist). Drawing on social identity, optimal distinctiveness, and balance theories, four studies examined the nature of negational identity relative to affirmational identity. One study explored the conditions that increase negational identification and found that activating the need for distinctiveness increased the accessibility of negational identities.
Three experiments examine the relationship between past performance and strategies and risk attitudes in integrative negotiations. We hypothesized that past performance would affect negotiators' willingness to embrace two types of risk: strategic (i.e., information sharing in the present) versus contractual (i.e., uncertainty about the future). Consistent with the hypothesis that past success promotes strategic risk taking, dyads with a history of success were more integrative than dyads with a history of failure in Experiment 1.
