Social reinforcement and norm learning interact with social media design to amplify moral outrage in online networks.

This study explores the role of gender ideologies in moderating social judgments of gender norm violators. Three hundred and eleven participants evaluated a male or a female target who was either a primary breadwinner or a primary caregiver. Attributions of personal traits, moral emotions, and marital emotions were examined. Results showed that both traditional and egalitarian individuals appli...

Are verbal reports of disgust in moral situations specific indicators of the concept of disgust, or are they used metaphorically to refer to anger? In this experiment, participants read scenarios describing a violation of a norm either about the use of the body (bodily moral) or about harm and rights (socio-moral). They then expressed disgust and anger on verbal scales, and through facial expre...

Moral psychology research has highlighted several factors critical for evaluating the morality of another's choice, including the detection of norm-violating outcomes, the extent to which an agent caused an outcome, and the extent to which the agent intended good or bad consequences, as inferred from observing their decisions. However, person-centered accounts of moral judgment suggest that a m...

Aversive emotional reactions to real or imagined social harms infuse moral judgment and motivate prosocial behavior. Here, we show that the neurotransmitter serotonin directly alters both moral judgment and behavior through increasing subjects' aversion to personally harming others. We enhanced serotonin in healthy volunteers with citalopram (a selective serotonin reuptake inhibitor) and contra...

We develop a simple yet realistic model of income insurance, where the individual’s ability and willingness to work is treated as a continuous variable. In this framework, income insurance not only provides income smoothing, it also relieves the individual from particularly burdensome work. As a result, the individual adjusts his labor supply in a continuous fashion to the implicit tax wedge of...

Bank crises, by interrupting liquidity provision, have been viewed as resulting in welfare losses. In a model of banking with moral hazard, we show that second best bank contracts that improve on autarky ex ante require costly crises to occur with positive probability at the interim stage. When bank payoffs are partially appropriable, either directly via imposition of fines or indirectly by the...

We consider the combined impact of agency problems and behavioural factors on venture capital/entrepreneur contracting and performance. Particularly, we develop a behavioural game-theoretic model in which a venture capitalist and an entrepreneur negotiate over their respective equity shares, and then exert value-adding efforts in running the business. Double-sided moral hazard exists in that bo...

This paper presents a framework for the integration of values (internalized norms) in a positive analysis of institutions and institutional change. Informal, norm-based institutions and formal – legal, economic, and political – institutions are co-determined as an equilibrium in the relations among economic and political actors. The paper discusses various ways that formal institutions influenc...

Theory of mind, the capacity to understand and ascribe mental states, has traditionally been conceptualized as analogous to a scientific theory. However, recent work in philosophy and psychology has documented a “side-effect effect” suggesting that moral evaluations influence mental state ascriptions, and in particular whether a behavior is described as having been performed ‘intentionally.’ Th...
