Religion,discrimination and trust across three cultures

We propose that religion impacts trust and trustworthiness in ways that depend on how individuals are socially identified and connected. Religiosity and religious affiliation may serve as markers for statistical discrimination. Further, affiliation to the same religion may enhance group identity, or affiliation irrespective of creed may lend social identity, and in turn induce taste-based discrimination. Religiosity may also relate to general prejudice. We test these hypotheses across three culturally diverse countries. Participants׳ willingness to discriminate, beliefs of how trustworthy or trusting others are, as well as actual trust and trustworthiness are measured incentive compatibly. We find that interpersonal similarity in religiosity and affiliation promote trust through beliefs of reciprocity. Religious participants also believe that those belonging to some faith are trustworthier, but invest more trust only in those of the same religion—religiosity amplifies this effect. Across non-religious categories, whereas more religious participants are more willing to discriminate, less religious participants are as likely to display group biases.     

Culture, caution, and trust

Trust is an important determinant of economic development. Understanding its origins is therefore critical. We develop a principal-agent model with heterogeneous players to determine the aggregate amount of trustworthiness and trust in a society. People are distributed according to their preference toward caution, which we model as loss aversion. The first two moments of the distribution across principals and agents—along with institutional quality—are critical to the process by which trustworthiness and trust are formed. A direct effect suggests that more caution leads to less societal trust. An indirect effect of greater caution, working through trustworthiness, leads to more trust. Paradoxically, the net effect is almost always positive. The results are similar when we use expected utility theory. Different distributional assumptions can influence the results.     

DO LIES ERODE TRUST?

Does honesty promote trust and trustworthiness? We investigate how being lied to (versus told the truth) in a Gneezy deception game affects behavior in a subsequent trust game with different players. Using a design that controls for potential treatment effects on payoffs, mood, and beliefs about the overall propensity for honesty in the experiment, we find that the specific experience of being lied to significantly erodes trust and trustworthiness.     

THE INTERPLAY OF INEQUALITY AND REFERENCE DEPENDENCE WITH TRUST AN EXPERIMENTAL STUDY

Using a canonical trust game, we investigate whether the inequality of endowment between trustor and trustee and the acquired versus permanent financial state affect trust and trustworthiness. We found that trust and trustworthiness are reference‐dependent and that individuals with permanent financial state receive more trust and are more trustworthy than others. In our experiment, unequal endowments do not significantly affect trust, but trustworthiness increases significantly when the trustor is poorer.     

Trust, trustworthiness, and risk in rural Paraguay

This dissertation looks at the relationship between trust, trustworthiness, and risk aversion in a rural Paraguayan setting. The first chapter of this dissertation looks at theft between farmers. Rural areas of developing countries often lack effective legal enforcement. However, villagers who know each other well and interact repeatedly may use implicit contracts to minimize crime. I construct a dynamic limited-commitment model in which a thief cannot credibly commit to forego stealing from his fellow villagers but may be induced to limit his stealing by the promise of future gifts from his potential victim. Using a unique survey from rural Paraguay which combines traditional data on production with information on theft, gifts, and trust, as well as with experiments measuring trust and trustworthiness, I test whether the data is consistent with predictions from the dynamic model. The results provide evidence that, in contrast with predictions from a one-period model with an anonymous thief, farmers do implicitly contract with one another to limit theft. Farmers who have more close family members in their village give fewer gifts, and farmers with plots which are more difficult to steal from give fewer gifts, experience less theft, and trust more. Gift-giving increases when trust is lower and the threat of theft is greater, turning the social capital literature on its head. The second chapter of this dissertation looks at a different linkage between trust, trustworthiness, and risk. Trusting behavior in general and play in the traditional trust experiment specifically depend both on trust beliefs and on levels of risk aversion. I ran two experiments with a diverse set of subjects in fifteen villages of rural Paraguay, the traditional trust experiment and a new experiment measuring only risk aversion. I find that risk attitudes are highly predictive of play in the trust game. In addition, omitting risk aversion as a regressor in trust regressions significantly changes the coefficients of important explanatory variables such as gender and wealth.

Do reputation feedback systems really improve trust among anonymous traders? An experimental study

Feedback systems are claimed to be a crucial component of the success of electronic marketplaces like eBay or Amazon Marketplace. This article aims to compare the effects of various feedback systems on trust between anonymous traders, through a set of experiments based on the trust game. Our results indicate that trust is significantly improved by the introduction of a reputation feedback system. However, such mechanisms are far from being perfect and are vulnerable to strategic ratings and reciprocation. Our findings indicate that some changes in rating rules may significantly improve the efficiency of feedback systems, by avoiding strategic rating or reciprocation, and hence stimulate trust and trustworthiness among traders. In particular, a system in which individuals are not informed of their partner's rating decision before making their own decision provides better results, both in terms of trust and earnings.     

The Impact of Payoff Interdependence on Trust and Trustworthiness

Abstract. In one‐shot investment games where each player's payoff is a convex combination of own and other's profit, we measure trust by the amount given to the trustee and trustworthiness by the amount returned to the trustor by the trustee. Does the degree of payoff interdependence increase both trust and trustworthiness or one but not the other or neither of them? According to our experimental data, trust remains unaffected by the extent of interdependence whereas trustworthiness reacts positively to it.     

Collective Trust Behavior*

This paper investigates trust behavior in situations where decision‐makers are large groups and the decision mechanism is collective. Theories from behavioral economics and psychology suggest that trust in such situations may differ from interindividual trust. The experimental results here reveal a large difference in trust but not in trustworthiness between the individual and collective setting. Furthermore, a field experiment captures the determinants of collective trust behavior among two Swedish cohorts. Beliefs about the other group and one's own group are strongly associated with collective trustworthiness and trust behavior.     

Does competition foster trust? The role of tournament incentives

Members of organizations are often called upon to trust others and to reciprocate trust while at the same time competing for bonuses or promotions. We suggest that competition affects trust not only within dyads including direct competitors, but also between individuals who do not compete against each other. We test this idea in a trust game where trustors and trustees are rewarded based either on their absolute performance or on how well they do relative to players from other dyads. In Experiment 1, we show that competition among trustors significantly increases trust. Competition among trustees decreases trustworthiness, but trustors do not anticipate this effect. In Experiment 2, we additionally show that the increase in trust under competition is caused by a combination of increased risk taking and lower sensitivity to non-financial concerns specific to trust interactions. Our results suggest that tournament incentives might have a “blinding effect” on considerations such as betrayal and inequality aversion.     

Trust and trustworthiness across different age groups

We examine the degree of trust and trustworthiness in an experimental trust game with 662 participants from six different age groups, ranging from 8-year-olds to retired persons. Although both trust and trustworthiness have been identified as fundamental pillars for efficient economic interactions, economic research has devoted little attention to measuring their strength in different age groups. In our experiment subjects interact with members of the same age group. We find that trust increases almost linearly from early childhood to early adulthood, but stays rather constant within different adult age groups. Trustworthiness prevails in all age groups.     

Whom do you distrust and how much does it cost? An experiment on the measurement of trust

We advance the measurement of trust in economics in two ways. First, we highlight the importance of clearly identifying the target of trust, particularly for obtaining concordance between attitudinal and behavioral measures of trust. Second, we introduce a novel behavioral measure of (dis)trust, based on individuals? willingness to pay to avoid being vulnerable to the target of trust. We conduct an experiment in which we vary the target of trust among passersby at several locations around a city, measuring both behavioral distrust and trust attitudes towards these varying targets. We find that subjects discriminate based on perceived characteristics of different targets in determining whether to trust, in a manner consistent with trust elicited using attitudinal measures and with actual trustworthiness. Risk aversion and altruism do not correlate highly with our measure of distrust.     

Group status,minorities and trust

We present the results of an experiment measuring the impact of low group status and relative group size on trust, trustworthiness and discrimination. Subjects interact with insiders and outsiders in trust games and periodically enter markets where they can trade group membership. Low status and minority subjects have low morale: that is, they comparatively dislike being low status and being minority subjects. Group discrimination against low status and minority subjects is unchanged. However, low status subjects are deferential to high status subjects in terms of comparatively higher trust, and minority subjects are deferential to majority subjects in terms of comparatively higher trustworthiness.     

Promises and lies: can observers detect deception in written messages

We design a laboratory experiment to examine predictions of trustworthiness in a novel three-person trust game. We investigate whether and why observers of the game can predict the trustworthiness of hand-written communications. Observers report their perception of the trustworthiness of messages, and make predictions about the senders’ behavior. Using observers’ decisions, we are able to classify messages as “promises” or “empty talk.” Drawing from substantial previous research, we hypothesize that certain factors influence whether a sender is likely to honor a message and/or whether an observer perceives the message as likely to behonored: the mention of money; the use of encompassing words; and message length. We find that observers have more trust in longer messages and “promises”; promises that mention money are significantly more likely to be broken; and observers trust equally in promises that do and do not mention money. Overall, observers perform slightly better than chance at predicting whether a message will be honored. We attribute this result to observers’ ability to distinguish promises from empty talk, and to trust promises more than empty talk. However, within each of these two categories, observers are unable to discern between messages that senders will honor from those that they will not.     

Learning to trust in indefinitely repeated games

Although it is well known that trust and trustworthiness (i.e., the fulfillment of trust) are important behaviors for the fulfillment of incomplete contracts, less is known about how the economic environment influences them. In this paper we design an experiment to examine how exogenously determined (stochastic) past relationship lengths affect trust and trustworthiness in new relationships. We find that shorter-lasting relationships have an immediate negative impact on both behaviors in the relationships that immediately follow, while longer-lasting relationships have the opposite effect. The effect of stochastic end-points declines for trustworthiness but not for trust as subjects gain experience, indicating that trust is able to rebound when longer-lasting relationships follow shorter-lasting ones.     

It takes two to cheat: An experiment on derived trust

Social life offers innumerable instances in which trust decisions involve multiple agents. Of particular interest is the case when a breach of trust is not profitable if carried out in isolation, but requires an agreement among agents. In such situations the pattern of behaviors is richer than in dyadic games, because even opportunistic trustees who would breach trust when alone may act trustworthily based on what they believe to be the predominant course of action. Anticipating this, trusters may be more inclined to trust. We dub these motivations derived trustworthiness and derived trust. To capture them, we design a “Collective Trust Game” and study it by means of a laboratory experiment. We report that overall levels of trustworthiness are almost thirty percentage points higher when derived motivations are present, and this generates also higher levels of trust. In our set-up, the effects of derived trustworthiness are comparable in size to positive reciprocity, and more important than concerns for equality.     

异质型创业领导、嵌入授权对团队簇个体绩效的跨层次影响研究

团队簇创新和创业交互属性与领导的差异化嵌入授权行为关联紧密,而参与个体对彼此能力的互信是进行有效合作的前提。据此,关注能力互信氛围在团队绩效中的作用机理与外部情境能够有效解析异质型创业领导对团队簇个体绩效作用的相机变化效应。以创业型领导异质性、嵌入授权(结构、心理与认知授权)和能力互信氛围作为团队层次变量,将个体绩效作为个体层次变量,考察嵌入授权的跨层次中介以及能力互信氛围的调节作用。结果发现：内部比较优势导向异质性不直接影响成员个体绩效,而外部战略价值导向异质性则有助于促进个体绩效;嵌入授权在异质性与个体绩效间起中介作用;能力互信氛围在嵌入授权与个体绩效间起跨层次调节作用。根据研究结果,提出相关管理启示。     

Socioeconomic stratification and stereotyping: lab-in-the-field evidence from Colombia

In this study, we test the hypothesis that the Colombian system of socioeconomic stratification (SES), which ranks dwellings from one to six to calculate utility (public services) rates, may induce discrimination. To this end, a field experiment with around 1000 participants from Bogotá is carried out. The design includes a combination of a trust game and a dictator game and SES-contingent decisions. Results exclude the presence of pure preferences for discrimination, yet they confirm that low strata are associated with stereotypes of low trustworthiness. We also observe significant prosocial behavior in the low-income population, and most strikingly, we do not observe any difference in trustworthiness across different income levels.     

HUMAN NATURE, COMMUNICATION AND TRUST

ABSTRACT ** :  The facts that people can sometimes commit to fulfill promises even when there are no binding penalties and that kind and trusting acts are often reciprocated by trustworthy ones make possible forms of group action that might be ruled out in a hypothetical world of perfectly opportunistic individuals. I discuss some new experiments with a modified Berg, Dickhaut and McCabe (1995) ' trust game' that provide evidence that most subjects adhere to non-binding agreements, that many are prepared to rely on trust rather than use binding but moderately costly contracts, that the possibility of exchanging words rather than mere numerical proposals enhances trusting and trustworthiness, and that subjects are drawn to fair and efficient exchanges despite the self-interest model's prediction of outcomes more favorable to first-movers.     

Trust and trustworthiness in games: An experimental study of intergenerational advice

This paper investigates the development of conventions of trust in what we call intergenerational games, i.e., games played by a sequence of non-overplapping agents, who pass on advice on how to play the game across adjacent generations of players. Using the trust game of Berg et al. (1995) as our experimental decision problem, advice seems to decrease the amount of trustthat evolves when this game in played in an inter-generational manner in that it decreases the amount of money sent from Senders to Returners. Ironically, advice increases trustworthinessin that Returners tend to send more back. Further, subjects appear to follows conventions of reciprocity in that they tend to Send more if they think the Returners acted in a “kind” manner, where kind means the Sender sent more money than the receiver expected. Finally, while we find a causal relationship running from trustworthiness to trust, the opposite can not be established. We note that many of our results can only be achieved using the tools offered by inter-generational games. The inter-generational advice offered provides information not available when games are played in their static form. Combining that information with elicited beliefs of the Senders and Returners adds even more information that can be used to investigate the motives that subjects have for doing what they do.

A trust game in loss domain

In standard trust games, no trust is the default, and trust generates a potential gain. We investigate a reframed trust game in which full trust is default and where no trust generates a loss. We find significantly lower levels of trust and trustworthiness in the loss domain when full trust is default than in the gain domain when no trust is default. As a consequence, trust is on average profitable in the gain domain, but not in the loss domain. We also find that subjects respond more positively to higher trust in the loss domain than in the gain domain.
