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.
We develop and apply a general framework for using shocks from natural experiments to estimate key parameters in a class of structural models, via recentered instruments that exploit knowledge of the shock assignment process. This design-based identification approach imposes no restrictions on how model unobservables relate to predetermined variables, and yields a new class of optimal instruments. We show how instrument recentering relaxes strong assumptions in models of the demand for differentiated products.
