Pay what you Want: A New Participative Pricing Mechanism
研究了“随心付”这种参与式定价机制，通过三个实地实验发现消费者支付的价格显著高于零，并分析了影响支付价格的因素，表明该机制可能增加卖家收入。
Pay what you want (PWYW) is a new participative pricing mechanism in which consumers have maximum control over the price they pay. Previous research has suggested that participative pricing increases consumers’ intent to purchase. However, sellers using PWYW face the risk that consumers will exploit their control and pay nothing at all or a price below the seller's costs. In three field studies, the authors find that prices paid are significantly greater than zero. They analyze factors that influence prices paid and show that PWYW can even lead to an increase in seller revenues.
