Extreme Participation: Product Ratings with Aggregation.

Abstract: Until now, the prevalence of extreme-valued ratings in online user-generating rating systems remained a puzzle. In this paper we show that if ratings are aggregated using the mean of sent-ratings, then with some constraints on equilibrium strategies, in all environments, the prevalence of extreme-valued ratings is driven by participation. That is, it is always the case that the more extremely a consumer feels about a product, the more likely she is to rate it. This is in contrast to hypotheses that extreme-valued ratings are simply accurate representative of consumers' valuations, or alternatively, that consumers distort their ratings towards the extreme. We prove this result in a two stage game in which messages from the first stage are aggregated and then sent to players acting in the second stage. The environment specifies a continuum of correlated types, and allows for an intrinsic valuation for messaging. We further apply this analysis to mechanisms in which sent-ratings are aggregated by their median, and to the class of mechanisms in which raters give a "thumbs up" or "thumbs down" rating.
