Cashless Stores and Cash Users
The emergence of cashless stores has led several cities and states to ban such stores. This article investigates this issue by characterizing consumers who pay cash for in-person purchases and consumers who do not have credit or debit cards. Using a random utility model, I estimate 1.3 to 30.9 percentage drop in average per-payment consumer surplus if all stores were to become cashless and when utility is measured by the cost of making a payment, security, and convenience. The conclusion provides a discussion of alternatives to cash for in-person purchases that may be needed before all ...

Consumer Use of Multiple Payment Methods
The paper investigates the degree to which buyers choose to diversify their use of payment methods for in-person purchases. Some buyers use only one payment instrument. Others combine the use of mostly cash, credit, debit cards, and a few paper checks and prepaid cards. To each survey respondent, I apply three concentration measures over the use of payment instruments. Results show that the degree of consumers' payment concentration exhibits almost no correlation with consumer demographics, payment volume, or aggregate value.

How People Pay Each Other: Data, Theory, and Calibrations
Using a representative sample of the U.S. adult population, we analyze which payment methods consumers use to pay other consumers (p2p) and how these choices depend on transaction and demographic characteristics. We additionally construct a random matching model of consumers with diverse preferences over the use of different payment methods for p2p payments. The random matching model is calibrated to the share of p2p payments made with cash, paper check, and electronic technologies observed from 2015 to 2019. We find about two thirds of consumers have a first p2p payment preference of cash. ...

How Currency Denomination and the ATM Affect the Way We Pay
I show how currency denomination and the ATM influence consumers' choice of whether to pay cash for in-person purchases. I identify transaction values above which consumers switch from paying cash to paying with cards. The sharpest changes in the share of cash payments occur at $20 and $40, which coincide with the observation that most ATMs in the United States dispense multiples of $20 bills. Other thresholds prevail at multiples of $5 and $10. The above thresholds generate asymmetries in consumer behavior where the share of cash payments increases for payments values just below the ...

Low-Income Consumers and Payment Choice
Low-income consumers are not only constrained with spending, but also with the type and variety of payment methods available to them. Using a representative sample of the U.S. adult population, this paper analyzes the low possession (adoption) of credit and debit cards among low-income consumers who are also unbanked. Using a random utility model, I estimate the potential welfare gains associated with policy options suggested in the literature to provide subsidized and unsubsidized debit cards to this consumer population.

Financial inclusion and consumer payment choice
This report examines similarities and differences among three groups of consumers: those without a checking or savings account (unbanked), bank account adopters who have used alternative financial services (AFS) in the past 12 months (underbanked), and bank account adopters who did not use AFS in the past 12 months (fully banked). Consumers in the three groups have different demographic characteristics, income, and payment behaviors: ?The payment behavior of the underbanked is similar to that of the fully banked. ?Unbanked consumers make fewer payments per month than the fully banked and the ...
