On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
We study dynamic information design for full implementation in dynamic supermodular games where players’ opportunities to revise their actions arrive stochastically. We show that noisy but conclusive bad news signals uniquely implement the largest equilibrium across all dynamic information structures. Such structures exhibit asymmetry, noise, and state-invariance: asymmetry skews future switching behavior—conditional on bad news not arriving—towards the designer-preferred action which incentivizes switching in the present; noise increases the probability that bad news does not arrive; state-invariance lifts the time-t optimality of continuation information structures to dynamic optimality. There is no multiplicity gap: the largest implementable equilibrium can be implemented uniquely. We discuss applications to macroeconomics, debt runs, and platform competition.
