The household effects of mortgage regulation

In the new CAMP Working Paper 07/2021, Aastveit, Juelsrud and Getz Wold evaluate the impact of mortgage regulation on child and parent household balance sheets, highlighting important trade-offs in terms of financial vulnerability. Using Norwegian tax data, they show that loan-to-value caps reduce house purchase probabilities, debt and interest expenses – thereby improving household solvency. Moreover, parents of first-time buyers also reduce their debt uptake, suggesting that concerns about regulatory arbitrage are unwarranted. However, the higher downpayment requirement also leads to a persistent deterioration of household liquidity. They show that this reduction in liquid buffers coincides with larger house sale propensities given unemployment, as households become more vulnerable to adverse income shocks.
