Fairness emerges as a relevant factor in redistributive preferences in surveys and experiments. We study experimentally the impact of varying the probability with which players are assigned to initial positions in Ultimatum Games (UGs). In the baseline case players have equal opportunities of...

We study the impact on payoff distribution of varying the probability (opportunity) that a player has of becoming the proposer in an ultimatum game (UG). Subjects' assignment to roles within the UG was randomised before the interactions. Subjects played 20 rounds anonymously and with random...

We report results from two different settings of a 3-player ultimatum game. Under the monocratic rule, a player is randomly selected to make an offer to two receivers. Under the democratic rule, all three players make a proposal, and one proposal is then extracted. A majority vote is required to...

We investigate experimentally the modification of initial chances to acquire advantaged positions in bargaining problems. In the baseline case players have equal opportunities to acquire the advantaged position. Chances become increasingly unequal across three treatments. We find: (1) The more...
