The study looked at how the length of a loan affects how likely people are to default on it. By analyzing data from a Czech bank, the researchers found that borrowers who are more likely to default are more influenced by how long the loan lasts rather than the interest rate. They also found that pricing loans based on risk might actually make people more likely to default, rather than helping to pick out good borrowers. The study shows that how well a loan performs depends on how long it lasts, and that the length of the loan affects how likely it is to be paid back on time.
