An Experimental Study of the Effects of Inequality and Relative Deprivation on Trusting Behavior

Several non-experimental studies report that income inequality and other forms of population-based heterogeneity reduce levels of trust in society. However, recent work by Glaeser et al. (2000) calls into question the reliability of widely used survey-based measures of trust. Specifically, survey responses regarding trust attitudes did not reflect subjects actual behavior in a trust game. In this paper, we conduct a novel experimental test of the effects of inequality on trust and trustworthiness. Our experimental design induces inequality by varying the show-up fees paid to subjects, in contrast to previous experiments that focus on broad cultural or national differences in trust. We do not find robust support for the hypothesis that inequality per se dampens trusting behavior among all subjects; however, we do find some evidence that trust and rustworthiness are influenced by an individuals relative position in the group. Finally, we confirm previous findings that common survey-based measures of social trust are not associated with actual trusting behavior.Trust, social capital, heterogeneity, inequality, experiment

Terpenoid-Induced Feeding Deterrence and Antennal Response of Honey Bees

Multiple interacting stressors negatively affect the survival and productivity of managed honey bee colonies. Pesticides remain a primary concern for beekeepers, as even sublethal exposures can reduce bee immunocompetence, impair navigation, and reduce social communication. Pollinator protection focuses on pesticide application guidelines; however, a more active protection strategy is needed. One possible approach is the use of feeding deterrents that can be delivered as an additive during pesticide application. The goal of this study was to validate a laboratory assay designed to rapidly screen compounds for behavioral changes related to feeding or feeding deterrence. The results of this investigation demonstrated that the synthetic Nasonov pheromone and its terpenoid constituents citral, nerol, and geraniol could alter feeding behavior in a laboratory assay. Additionally, electroantennogram assays revealed that these terpenoids elicited some response in the antennae; however, only a synthetic Nasonov pheromone, citral, and geraniol elicited responses that differed significantly from control and vehicle detections

Did the Devil Make Them Do It? The Effects of Religion in Public Goods and Trust Games*

We test whether religious affiliation and participation in religious services are associated with behavior in public goods and trust games. Overall, religious affiliation is unrelated to individual behavior. However, we find some weak evidence that among subjects attending religious services, increased participation is associated with behavior in both public goods and trust games

Do Liberals Play Nice? The Effects of Party and Political Ideology in Public Goods and Trust Games

We test the conventional wisdom that political ideology is associated with generosity or compassion by comparing the behavior of experimental subjects in public goods or trust games. We find that self-described liberals and those identifying more closely with the Democrat party are just as likely to free-ride as conservatives or Republican-leaners; likewise, political ideology is unrelated to observed trusting behavior or trustworthiness in a bilateral trust game

Inequality, Group Cohesion, and Public Good Provision: An Experimental Analysis

Recent studies argue that inequality reduces group cohesiveness and dampens support for expenditures on public goods and social programs. In light of competing theoretical explanations and mixed empirical evidence of the effect of inequality on public goods provision, we conduct a test using a public goods experiment. Our design introduces inequality by manipulating the levels and distributions of fixed payments given to subjects for participating in the experiment. When made salient through public information about each individual's standing within the group, inequality in the distribution of fixed payments reduces contributions to the public good for all group members

Social Capital and Contributions in a Public-Goods Experiment

Empirical studies from across the social and behavioral sciences find that social capital is associated with various measures of well-being, including economic growth and mortality. however, such evidence is plagued by concerns that survey-based measures of trust and participation are not meaningful; in particular, recent experimental evidence from trust games conducted by Edward L. Glaeser et al. (2000) calls into question the efficacy of the most prevalent measures of social capital employed in the literature
