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 examine a persuasion game where concerns about future credibility are the sole source of current credibility. A long-run sender plays a cheap talk game with a sequence of short-run receivers. Even with perfect monitoring, long-run incentives do not perfectly substitute for ex-ante commitment to reporting strategies at the stage game. We then show that different methods of augmenting or garbling history can better harness long-run incentives and expand the Pareto frontier. In particular, a `review aggregator’ can implement average payoffs and information structures arbitrarily close to those available under ex-ante commitment. Finally, we examine applications to e-commerce and finance.
