The Ultimatum Game is a famous sequential, two - player game intensely studied in Game Theory. A proposer can offer a certain fraction of some amount of a valuable good, for example, money. A responder can either accept, in which case the money is shared accordingly, or reject the offer, in which case the two players receive nothing . While most authors suggest that the fairest split of 50% vs. 50% would be the equilibrium solution, recently R. Suleiman ( An aspirations - homeostasis theory of interactive d eci sions (2014) http://vixra.org/abs/1403.0029 ) suggested the Golden Ratio , 0.6 18 ... , to b e the solution and argu ed that such a partitioning would be considered fair by both sides. He provided a justifi ca tion in terms of an approach termed aspirations - homeostasis theory . The main idea is that responders tend to accept the minor fraction of the Golden Ratio because they feel that this fraction equals , in comparison to the larger fraction ob tained by the proposer, the ratio of the larger fraction and the whole amount. Here we give an alternative explanation to that suggested solution, which complements the reasoning by Suleiman (2014) and is based on infinite continued fractions.
