OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
The Market for Product Reviews
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.
