We analyse team dictator games with different voting mechanisms in the
laboratory. Individuals vote to select a donation for all group members. Standard
Bayesian analysis makes the same prediction for all three mechanisms: participants
should cast the same vote regardless of the voting mechanism used to determine the
common donation level. Our experimental results show that subjects fail to choose the
same vote. We show that their behaviour is consistent with a joy of ruling: individuals
get an extra utility when they determine the voting outcome.
