OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Flooded House or Underwater Mortgage? The Macrofinancial Implications of Climate Change and Adaptation
I study the implications of climate change on housing markets, mortgage credit, and private adaptation. Households are exposed to physical climate risks that damage housing and degrade land, which is inelastically supplied. While the exposure to climate risk weakens housing demand, I show that the materialization of climate change raises house prices over time, as habitable land becomes increasingly scarcer. In frictionless markets, price signals support efficient adaptation. However, credit-constrained households have weaker incentives to adapt to climate change, indicating that pricing alone may be insufficient. Unequal adaptation reinforces wealth inequality and contributes to further habitat loss. As this tightening credit constraints for future generations, the private adaptation gap widens over time. I show that a shift from constrained homeownership to a rental model with unconstrained owners can lead to more efficient adaptation.
