The End of Tourist Traps: The Impact of Review Platforms on Quality Upgrading

Dante Donati

No 9834, CESifo Working Paper Series from CESifo

Abstract: Asymmetric information can distort market outcomes and harm welfare. This paper examines how cheaper access to review platforms affects consumer behavior and firms’ incentives to improve product quality in markets where information is traditionally limited. I first develop a consumer search model with firms making endogenous quality decisions. The model predicts that lower search costs shift demand toward higher-quality producers, raising firms’ incentives to upgrade quality, especially for firms selling ex-ante lower-quality products. I then use online ratings as a proxy for reduced consumer search costs and estimate their impact on the restaurant industry in Rome, leveraging the abolition of mobile roaming charges in the EU in 2017 for identification. Using a unique dataset that combines monthly Tripadvisor information with administrative social-security records, I find that revenues and total employment in higher-rated restaurants increased by 4–10% after the internet price drop. The effects were particularly strong for less visible high-rated establishments, indicating a complementarity between ratings and navigation platforms. Meanwhile, the probability for lower-rated restaurants to exit the market doubled, while surviving lower-rated establishments hired workers with higher wages and better experience, ultimately improving their online reputation. These findings highlight the significant role of review platforms in mitigating asymmetric information and fostering quality upgrades.
