Consumer Willingness to Share Payments Data: Trust for Sale?

Using Dutch survey data, we show how consumer willingness to allow access to payments data depends on the type of data user (the consumer’s own bank, another bank, or a Big Tech), financial incentives and trust in the data user. Consumers are most willing to grant access to their own bank. Their propensity to share their payments data increases with their trust in the providers of these services. An explicit financial reward can tempt people to accept offers from other providers. Big Tech firms on average have to offer stronger incentives than banks, because people trust them the least.
