• Resumen

  • Consumer credit regulations usually require that lenders disclose interest rates. However, in the absence of specific prominence requirements, lenders can conceal the interest rate in the fine print while still complying with the law. I examine the effect of such a strategy using a field experiment in Brazil in which a credit card company offered their clients payment plans to pay off their balances. Using randomized contract interest rates and the degree of rate disclosure, I show that most clients are rate sensitive, whether or not rates are prominently disclosed. The elasticity of payment plan enrollment with respect to the interest rate ranges from ?0.711 to ?0.880. High-risk clients are an exception; these clients are rate sensitive only when disclosure is prominent. I also show that clients are influenced by nudges that favor longer-term contracts. Conditional on enrollment, the proportion of clients who choose a longer-term contract is 40 percentage points higher when a longer-term contract is featured in the advertisement layout. This effect, however, is weaker when stakes are higher. Data, as supplemental material, are available at http://dx.doi.org/10.1287/mnsc.2015.2281. This paper was accepted by Wei Jiang, finance.
