Abstract: Abstract The issuance of central bank digital currencies became a real policy issue after the announcement of Facebook’s Libra. Which types of product attributes should central bank digital currencies have to be widely accepted? We answer this question by analyzing consumers’ acceptance of hypothetical payment methods. We used Japanese data from the 2019 Financial Literacy Survey to estimate a model of consumers’ ranking of the frequency of the use of five payment methods via three statistical models. The estimates of three models showed that the respondents to the survey value payment methods with shorter transaction times and mobile payment methods. Based on the estimates of these models, we conducted counterfactual simulations for the introduction of the hypothetical mobile version of noncash payment methods that required a shorter transaction time. We found that these hypothetical products would be the most frequently used payment methods on average; however, respondents with experience of financial troubles and with small financial asset holdings would use them less frequently. The results suggest that if the Bank of Japan wanted to issue a central bank digital currency that would be used almost every day as a replacement for cash, policy tools should be utilized to encourage the use of it by these groups as well.
