“…A rich set of control variables, already established as influencing credit behaviours, was used to investigate the influence of financial literacy on the interest rate associated with mortgage debts, as well as the probability of refinancing a mortgage. A close link between the socio‐economic factors, financial standing, credit scores and, consequently, loan prices, is well‐documented in the literature (Arya et al., 2013; Bialowolski et al., 2020c; Cuesta & Sepulveda, 2018; Davies et al., 2019; Hollo & Papp, 2007; Kamleitner & Kirchler, 2007).
