Financial literacy, risk aversion and choice of mortgage type by households

This paper analyzes how financial literacy and reported willingness to take
financial risk impact a household’s choice of mortgage type. The results show that
households reporting higher financial literacy and lower risk aversion are 55 to 97 % more likely to opt for interest-only mortgages. The results are robust to alternative explanations such as the involvement of financial advisors, the effect of peers, experience with prior home-ownership, and house price expectations. In general, alternative mortgage products, as opposed to traditional mortgages, are chosen by wealthier, older, and/or more sophisticated households that are more likely to have a greater understanding of the risks and benefits associated with these products.
