This paper reports the results of a cross-country comparison between Austria andJapan for an experimental 3-personcoalition formation ultimatum game. The experimental design allows thecomparison with respect to three decisions. (i)The coalition decision, (ii) proposers' demand behavior in 2- and 3-personultimatum subgames, and (iii) theresponders' behavior in these subgames. In contrast to other cross-culturalstudies in experimental bargainingenvironments we can not find any (significant) difference in behavior betweensubjects in Austria and Japan. Weattribute the behavioral similarities mainly to a subtle focal point andresponder competition effect, which wipe outpossible cultural differences. Our conclusion is that even in environments -like bargaining - where cultural differencesmay play a prominent role the show-up of these differences is highly sensitiveto the exact context in which people act.
