Abstract
Household inaction in mortgage refinancing is pervasive despite financial incentives to take action. Inactive households implicitly cross-subsidize active households, allowing competitive lenders to set lower average mortgage rates. To provide a money-metric assessment of this cross-subsidy, we build a model of household refinancing behaviour and structurally estimate it on rich administrative data on the stock of loans in the U.K. mortgage market, an institutional setting well-suited to this calculation. The model and data reveal the existence of sizeable cross-subsidies, and reveal that cross-subsidies flow from relatively poorer households and those located in less-wealthy areas towards households that are richer and located in wealthier areas. These findings highlight how the design of household finance markets can contribute to wealth and income inequality.
