An Experiment on Retail Payments Systems
通过理论模型和实验研究零售交易中现金与电子支付的采用和使用，发现买家经济激励对电子支付扩散至关重要，但无法完全解释其采用选择。
We develop a novel theoretical and experimental framework to study adoption and use of cash versus electronic payments in retail transactions. The design allows us to assess the behavioral impact of sellers' service fees and buyers' rewards from using electronic payments. In the experiment, buyers and sellers faced a coordination problem, independently choosing a payment method before trading. Sellers readily adopted electronic payments but buyers did not. Eliminating service fees or introducing rewards significantly increased adoption and use of electronic payments. Buyers' economic incentives were crucial for the diffusion of electronic payments but cannot fully explain their adoption choices.
