Charitable giving under inequality aversion and social capital.

A Japanese General Social Survey is used to re-examine how voluntary giving is associated with inequality aversion, and how the relationship differs between high- and low-income groups. This paper also investigates how social capital influences that relationship. The key findings are that (1) the level of voluntary giving increases with inequality aversion for high-income groups, but not for low-income groups, and (2) social capital accumulated in the respondent’s residential area reinforces the positive influence of inequality aversion on voluntary giving for high-income groups only.
