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.
Pigou (1920) pointed to uncompensated damage done to surrounding woods by sparks from railway enginesas the canonical example of an environmental externality. We study a modern corollary — illegal tropical forest fires used for clearing land — using 15 years of daily satellite data covering over 107,000 fires across Indonesia. We exploit variation in wind speed and in who owns surrounding land to generate variation in the degree to which the use of fire at a given time and place represents an externality. We find firms overuse fire relative to a case where all spread risks are internalized. However, firms appear partially sensitive to the risks of government punishment, which deters them from burning near protected forest or populated areas on particularly windy days. Counterfactuals suggest that if firms treated all surrounding land the way they treat neighboring populated areas, fires would be reduced by 80 percent.
