This study focuses on behavioral reactions to unequal distributions of
wealth. In an experimental study it is demonstrated that if a group i
s in a position to provide a public good, group members seize the oppo
rtunity to redistribute wealth. Redistribution of wealth through provi
sion of public goods was more extreme if the initial distribution of w
ealth was incongruent with the group members' inputs (in terms of effo
rt) than if it was congruent with those inputs. Results are interprete
d in terms of equity theory and status-value theory.
