摘要｜Abstract
Using new data from Clover, the market-leading point-of-sale platform in the U.S., and Fiserv, the largest payments processor in the U.S., we document how consumers pay for goods and services. A key feature of the data is the availability of transaction data at the merchant level, where we observe cash, checking, debit card, and credit card payments. We find that there is substantial heterogeneity in payment methods across merchants, varying across industries, regions, and consumer demographics. This finding has important implications because merchants pay heterogeneous fees for accepting different payment methods. To help understand and interpret our findings, we develop and estimate a structural model to understand how payment choices and the associated fees impact merchants and consumers. We show that accounting for this heterogeneity in payment methods across merchants is essential for assessing the winners and losers of card rewards programs. We find that both cash and debit card users help subsidize card rewards, but the subsidies are perhaps smaller than previously believed, given the penetration and concentration of credit cards in the U.S.
