Study: Groupon’s merchant quality is on the downslide

Have you had the feeling the quality of Groupon deals is going down? If so, you’re right. A report released this morning by Giorgos Zervas, a postdoctoral fellow of computer science at Yale University, shows that the average rating of a Groupon merchant before a deal runs is declining as Groupon matures. Zervas and other researchers had shown earlier that a business’s individual Yelp ratings dropped after running a Groupon. Yelp ratings by Groupon customers were, on average, 10% lower than those of their peers. (Disclosure: I met Zervas after the initial study and offered my theory that the average Yelp rating of merchants featured would be declining.)
