Yelp Reviews News

Giorgos Zervas is in the news again (with Michael Luca of Harvard Business School), this time for his work on filtered/fake Yelp reviews.  See also this piece in the Wall Street Journal blog.  High-level issue:  filtered reviews are on the rise, as businesses recognize that social media reviews can be important to their business.  The work is quite timely given the recent NY Attorney General's investigation into fake reviews that led to a number of fines.
