This paper presents an experimental study that compares ethnic heterogeneous teams (composed of both Danish and Chinese) with ethnic homogenous teams (composed of only Danish or only Chinese) on creative production. The characteristic of tasks is manipulated: well-defined or ill-defined creative task.
The paper finds that heterogeneous teams get more creative production than homogenous teams in solving the well-defined task. No significant difference was found in the creative production for the ill-defined task. The paper demonstrates that the creative production in ethnic heterogeneous teams will depend on the characteristic of the creative task.
