The owners of this dataset conducted a framed field experiment to explore a situation where individuals have potentially competing social identities, in order to understand how group identification and socialisation affect in-group favouritism and out-group discrimination. The Dictator Game and the Trust Game were conducted in Vietnam’s Ho Chi Minh City on two groups of high school students with different backgrounds, i.e., French bilingual and monolingual (Vietnamese) students. 

There are three treatments in the experimental design, capturing pure in-group condition (same school - same language scheme); in-group stranger condition (same school - different language scheme) and outgroup condition (different school - same language scheme).
