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 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.
