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 propose a model of product reviews with honest and fake reviews in order to study the value of information provided on platforms like TripAdvisor, Yelp, etc. In every period, a review is posted which is either honest, i.e., it reveals the reviewer’s true experience with the product/service, or fake, i.e., it is fabricated in order to manipulate the public’s beliefs. We establish that the equilibrium is unique and derive a number of robust and interesting results. While fake agents are able to manipulate the public’s beliefs, aggregation of information takes place as long as some of the reviews are honest.
