Do credit card companies screen for behavioural biases?

Using granular data on the contract terms and design details of more than 1.3 million credit card offers, we document how card issuers shroud unappealing, back-loaded features of an offer (e.g., high default APRs, late or over-limit fees) via the position of the information, font size, or complexity of the language used. More heavily shrouded offers that rely on back-loaded fees are also more likely to be offered to less-educated consumers. In addition, we document a novel interaction between behavioral screening and adverse selection: Using changes in state-level unemployment insurance (UI) as positive shocks to consumer creditworthiness, we show that issuers rely more on shrouded and back-loaded fees when UI increases, especially for less-educated consumers. Card issuers weigh short-term rent maximization against increased credit risk when targeting consumers' behavioral biases.
