Are people samaritans or avengers

The aim of this experiment is twofold. First of all, I want to compare the human tendency to punish unfair behavior to the desire to help victims of that unfairness, in presence of a budget constraint and without the expectation of a long-run pecuniary gain. Secondly, I want to check whether players'behavior changes when the initial endowment is earned and not randomly assigned. Our experiment frame is the Solomon's game.
