Bachelor Thesis from the year 2020 in the subject Gender Studies, grade: 1,0, Leuphana Universität Lüneburg (IVWL), language: English, abstract: In this thesis, it is investigated whether students at the Leuphana University express gender- and nationality-based Intergroup bias. Using an online experiment, it is employed a well-known allocation game in experimental economics (Ultimatum Game) on four different groups to examine whether subjects show ingroup favoring (outgroup disfavoring) behavior. It is found that subjects do not differentiate in their choices based on gender. However, it is observed a discriminatory behavior among international participants, as they offer German participants 46 cents less than they offer other international participants. Results from a logistic regression analysis also show that internationals are 26.4 percentage points more likely to discriminate against at least one outgroup. However, identification levels with the ingroup have no significant effects on subjects' choices. Aside from that, other explanatory variables like age, work, and living situation all reveal insignificant effects on subjects' decisions in the two phases of the game.
