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.     

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.     

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.     

The formation of risk sharing networks

This paper examines the formation of risk sharing networks in the rural Philippines. We find that geographic proximity–possibly correlated with kinship–is a major determinant of mutual insurance links among villagers. Age and wealth differences also play an important role. In contrast, income correlation and differences in occupation are not determinants of network links. Reported network links have a strong effect on subsequent gifts and loans. Gifts between network partners are found to respond to shocks and to differences in health status. From this we conclude that intra-village mutual insurance links are largely determined by social and geographical proximity and are only weakly the result of purposeful diversification of income risk. The paper also makes a methodological contribution to the estimation of dyadic models.     

Township-village enterprises,local governments and rural communities: the Chinese village as a firm during economic transition1

The nature of TVEs and the real functions of township-village governments are rooted in the Chinese township-village organization. The management of common property in a village group or a rural community is quite different from management in a situation where the boundaries of common property are unclear. Before economic reform, the cooperative elements or interspecific resources, such as low information costs, kinship ties, trust and cooperative spirit belonged in common to all villagers, yet cooperation was absent because the Chinese state appropriated the collective benefits. During the course of reform, the link between village official and state is being gradually broken down and the official is returning to his own village organization. The original interspecific resources of villagers and the identity of the village leader as government official are institutionalized as specific contractual relations in China's reform circumstances. The Chinese village behaves as a firm-type organization and the collective benefits can be internalized during the economic transition.     

Decomposing trust and trustworthiness

What motivates people to trust and be trustworthy? Is trust solely “calculative,” based on the expectation of trustworthiness, and trustworthiness only reciprocity? Employing a within-subject design, we run investment and dictator game experiments in Russia, South Africa and the United States. Additionally, we measured risk preferences and expectations of return. Expectations of return account for most of the variance in trust, but unconditional kindness also matters. Variance in trustworthiness is mainly accounted for by unconditional kindness, while reciprocity plays a comparatively small role. There exists some heterogeneity in motivation but people behave surprisingly similarly in the three countries studied.     

TRUST,VALUES, AND FALSE CONSENSUS

Individuals’ beliefs about the trustworthiness of a generic member of the population are both heterogeneous across individuals and persistent across generations. We investigate one mechanism yielding these dual patterns: false consensus. In the context of a trust game experiment, we show that the relationship between behavior and beliefs is consistent with individuals extrapolating their trust beliefs from their own trustworthiness and that this tendency continues even after substantial learning opportunities. We go on to provide evidence suggesting that one's own trustworthiness can be traced back to the values parents transmit to their children during their upbringing.     

Trust,risk and time preferences: evidence from survey data

The paper shows that time preferences and risk preferences are key covariates of self-reported trust. They both predict negatively a measure of generalized trust; however, risk aversion is positively correlated with an index of particularized trusting behaviour (which refers to the circle of known people).     

Online advertising networks and consumer perceptions of privacy

I use crowd-sourced ratings of website trustworthiness to investigate how consumers weigh the privacy impact of online advertising technologies. I find that using one additional advertising network is associated with a 0.7% increase in trust score and that using a behavioural network is associated with a 4.6% increase in trust score. These counter-intuitive results support the notion that consumers are unaware of the advertising technologies used by websites and their impact on privacy.     

Intertemporal substitution, risk aversion and ambiguity aversion

Summary. This paper axiomatizes a form of recursive utility on consumption processes that permits a role for ambiguity as well as risk. The model has two prominent special cases: (i) the recursive model of risk preference due to Kreps and Porteus [18]; and (ii) an intertemporal version of multiple-priors utility due to Epstein and Schneider [8]. The generalization presented here permits a three-way separation of intertemporal substitution, risk aversion and ambiguity aversion.Received: 5 August 2003, Revised: 12 March 2004, JEL Classification Numbers: D80, D81, D90.I am grateful to Larry Epstein for his guidance and invaluable advice, and to a referee for helpful comments and suggestions.     

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.     

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.     

Auctioning Risky Conservation Contracts

Conservation auctions have the potential to increase the efficiency of payments to farmers to adopt conservation-friendly management practices by fostering competition among them. The literature considers bidders that have complete information about the costs of adoption and optimal bidding behavior reflects this information advantage. Farmers seek information rents and bids decrease when risk aversion increases because farmers are more averse to losing the auction. We contribute to the literature by allowing for cost risk. Our paper shows that farmers must balance the risk of losing the auction (thus foregoing information rent) with the risk of submitting a bid that is not high enough to pay the costs of adopting conservation practices (thus incurring losses). We design an experiment to trade off these two risks and examine how risk aversion affects bidding behavior when participants face different sources and levels of risk. Our experiment contributes to a small literature on experimental auctions with risky product valuations. We find that participants decrease their bids as risk aversion increases, even in auctions with cost risk, suggesting that the risk of losing the auction dominates. These findings uncover new challenges for the practical implementation of conservation auctions as an efficient policy instrument.     

Can Risk‐Averse Households Make Risky Investments? The Role of Trust in Others

In this paper, using data from the Survey on Health, Ageing and Retirement in Europe (SHARE, 2006 and 2013 waves), we illustrate the link between individuals’ attitudes to financial risk combined with their willingness to trust others, and their investments in risky assets. Individuals who display either risk tolerance alone or – to a lesser extent – risk aversion and trust more frequently decide to buy risky assets. The comparison between Scandinavian and Mediterranean countries indicates that trust plays qualitatively different roles depending on the prevailing combination of risk attitude and trust in the area being studied.     

农户对新农合的需求研究:一个分析框架

对农民新农合的需求作了框架性研究。运用线形扩展支出模型定量分析了农民的支付能力。农村贫困人群确实存在支付能力问题。政府应对贫困人群的合作医疗筹资给予更大的支持力度。对于绝大数农民, 关键不在于支付能力, 而在于支付意愿。对农民的支付意愿构建了国家、社区、家庭和个人的四维解释框架。在国家层面, 影响因素主要是对政府的信任程度、政府的"机构能力"以及补贴的力度大小;在社区层面, 社会资本在社区健康融资中发挥着重要作用;家庭对合作医疗的支付意愿主要取决于其对参与的成本和收益的比较, 同时, 家庭成员内部风险分担机制和家庭之间风险分担机制也会对家庭的支付意愿产生影响。支付意愿还和农民的个人特征相关。     

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.     

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.     

Dissertation Abstract: Decision-Theoretic Models of Market Equilibration

There has been a surprising dearth of decision-theoretic approaches to market equilibration within the extended Arrow-Debreu-McKenzie framework. While game theory is replete with learning and evolutionary models in which Nash equilibria are not necessarily the only stable states of a game, general equilibrium theorists have generally been content to accept the attainment of competitive equilibrium as a matter of faith. The first two chapters of this dissertation advance the study of behaviorally plausible models of market equilibration. First, we develop the epsilon-intelligent competitive equilibrium algorithm. According to this model, the actions of minimally sophisticated agents based on local information will lead an exchange economy to approximate competitive equilibrium in a larger set of economics than Walras’ tatonnement. The algorithm also supports a behavioral interpretation of Negishi’s existence proof of competitive equilibrium. The second chapter is an empirical analysis of laboratory markets designed to test the extent to which human behavior is consistent with the algorithm’s behavioral restrictions, and suggest alternative hypotheses. The chief finding is that while subjects sufficiently sophisticated to consistently secure competitive utility for themselves exist, the majority are satisficers who follow small modifications of a simple utility-improvement rule.While general equilibrium theory has lacked a behaviorally plausible foundation of price equilibration, behavioral economic models typically ignore general equilibrium implications. In the third chapter of this dissertation, I present the surprising result that loss aversion and diminishing sensitivity for gains imply a greater redistribution of endowments than when otherwise identical preferences are reference-independent. The result is surprising because loss aversion was developed in part to account for the status quo bias, whereby people tend to value a good more when it is in their possession than when it is not. One might reasonably suspect trade to be inhibited by this bias. The counter-intuitive result is driven by the fact that, given the axiomatization of loss aversion and diminishing sensitivity for gains, the acquisition of some quantity of a good increases one’s taste for that good, thus perpetuating a taste for more trade.     

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 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.
