OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
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.
