Inequality, fairness and social capital

摘要

Inequality is often associated with negative societal consequences, but identifying a causal relationship is a daunting task. We provide evidence on the impact of unjust economic inequality on social interactions. Using a large-scale controlled experiment, we document that unjust inequality results in a significant decline in trust and trustworthiness. This ero-sion of social capital is associated with pessimistic beliefs about others' behavior and is muted if there is no direct link between the income-generating process and social interaction. Finally, our data do not support the view that higher status or wealth affects pro social attitudes: the successful are always more generous, whereas unsuccessful persons display the least efficient and generous behavior regardless of the status of the person who they interact with.
