2. Consider a three-person version of the Ultimatum Game: The Responder does not receive any money but instead decides whether to accept on behalf of a third-party bystander. Otherwise the structure is like that of the Ultimatum game in which the Proposer first decides how to split $10.00. Suppose that in this version you observe the Responder typically only accepts equal splits of $5.00 each (or splits that give a bigger share?), and typically rejects all other offers. How would you interpret this sort of result?
