"Most land rent is paid out as interest to banks and that bank credit is a major driver of increases in housing prices." In other words, unaffordable housing may not be a mere symptom of inequality, but rather, a key driver of it.
“Hudson (2012, 2018) has shown that most land rent is paid out as interest to banks and that bank credit is a major driver of increases in housing prices (“real estate is worth whatever the bank will lend against it”). Further empirical support is offered by Favara and Imbs (2015), and La Cava (2015) finds that this can explain the increase in the share of housing in capital income studied by Rognlie (2015). Ryan-Collins et al. (2017) and Turner (2017) argue that a self-reinforcing cycle between bank lending and land value increases has caused a shift in bank lending from business loans to mortgages and the inflation of land prices, and this has impaired financial stability, as also argued in Keen (2017).”
