摘要:
This paper analyzes the advertising spending patterns of US local restaurants that have different ratings on Yelp.com using a regression discontinuity design. Rating information on Yelp includes display ratings and review distributions. Yelps rounding algorithm creates a discontinuity in display ratings. Therefore, using a regression discontinuity design, I can identify the causal effect of a higher display rating on local restaurants advertising spending. I find that, for restaurants with ratings above 3, there is a significantly negative effect of display rating (i.e. Yelp stars) on advertising. An extra half-star on Yelp causes restaurant yearly advertising spending to reduce by about one-third, which is more than 5k dollars on average. However, when display ratings are constant between two thresholds, a higher (raw) average rating is associated with slowly increasing advertising. This is the first paper that distinguishes the raw average rating and the rounded display rating in the analysis of firms’ strategic response to word of mouth.
