Exploiting context-dependent preferences to protect borrowers – Q2 Publication by Barna Bakó

Focusing bias is one of the key contributors to over-borrowing. It describes how people, when making choices, give disproportionate attention and weight to attributes in which their options differ more. In a loan decision, a consumer excessively focuses on the eye-catching difference between getting the loan and not getting it, while ignoring the smaller differences between making and not making repayments. Here, we show a simple trick that nudges the consumer to increase attention on the repayment dimension. In two experimental studies involving one hypothetical loan decision, we demonstrate that the salience of getting the loan can be decreased if one offered plan includes high initial installments. This steeply decreasing installment plan (i.e., with initially high installments that decrease over time) offered alongside the usual flat installments plan (i.e., with equally sized repayments through the whole term) increases consumers’ attention to making repayments, and consequently, they attend less to obtaining the loan. When the choice set includes the steeply decreasing plan, we observe a decreased preference for the flat installment plan and a shift toward not borrowing. Additionally, making repayments on the loan is perceived as a greater burden, and more attention is given to making repayments when the steep plan is present. Policy may combat harmful loan consumption by prescribing the presentation of loan offers such that at least one option includes high initial repayments, which increases attention on making repayments.
