The IKEA-Effect occurs when co-creators over-evaluate their contribution to co-created products. Current research tries to explain this mechanism through a variety of theories like the Endowment-Effect, the Not-Invented-Here-Syndrome or the Extension of Self-Identity. But there are also other approaches to the positive evaluation self-created products like the Handmade-Effect, the Selfmade-Effect or the (Reverse) Trophy Effect.
Your task will be a systematic literature review about the Ikea-Effect and its related theories. For more information, please contact Melanie Osswald.
