The IKEA effect: When labor leads to love
通过四项实验（组装宜家盒子、折纸、搭乐高）发现，消费者对自己亲手制作的产品估值更高，甚至认为与专家作品价值相当，但这种效应只在成功完成任务时出现。
Abstract In four studies in which consumers assembled IKEA boxes, folded origami, and built sets of Legos, we demonstrate and investigate boundary conditions for the IKEA effect—the increase in valuation of self‐made products. Participants saw their amateurish creations as similar in value to experts' creations, and expected others to share their opinions. We show that labor leads to love only when labor results in successful completion of tasks; when participants built and then destroyed their creations, or failed to complete them, the IKEA effect dissipated. Finally, we show that labor increases valuation for both “do‐it‐yourselfers” and novices.
