    Information problems in health care and the multifaceted nature of hospital quality complicate hospital choice. Online reviews provide an accessible, salient means through which researchers and health care decision-makers can gather information about a hospital's quality of care, and given their increasing popularity, these measures may affect hospital choice and may have implications for hospital prices. Using the universe of hospital Yelp reviews and inpatient claims data for elective procedures in Florida from 2012 through 2017, we exploit exogenous variation in online hospital ratings over time to identify the effect of online reviews on hospital choice. We find that among admissions for elective, inpatient procedures, patients are willing to travel between 5 and 30 percent further to receive care from a hospital with a higher Yelp rating, relative to other hospitals in the market. We also find evidence that higher ratings translate into higher commercial payments from insurers, albeit with relatively modest magnitudes. Our results indicate that novel, accessible sources of quality information have the potential to affect health care decisions, with potential downstream effects on health care prices.

    This paper investigates the informational content of online reviews. For the case of hotels, we model how the length of the stay shapes the variance of review scores. Grounded on violations of temporal monotonicity, errors in recall and hedonic adaptation theories, we first present a characterization of how the consumption span affects the non-deterministic component of consumer satisfaction. Next, we conduct an empirical analysis using more than 525,000 individual reviews from Booking.com in 5 major European cities. Under a heteroskedastic framework, we document that individual ratings' volatility decreases with the length of the stay. This implies that online ratings from short stayers (short consumption episodes) are noisy signals of the underlying hotel quality. Furthermore, we show that greater volatility in hotel ratings translates into a lower share of useful reviews for subsequent consumers. Our findings offer relevant insights for platform design operators about the sources of ratings' volatility and how this affects social learning.

    Review systems including quantitative measures as well as text-based expression of experiences are omnipresent in today’s digital platform economy. This paper studies the existence of reputation inflation, i.e. unjustified increases in ratings, with a special focus of heterogeneity between experienced and non-experienced users. Using data on more than 5 million reviews from an online wine platform we compare consistency between numerical feedback and textual reviews as well as sentiment measures. We show that overall the wine platform displays strongly increasing numerical feedback over our time period from 2014 to 2020 while this is not the case for our control measures. This gap appears to be even stronger for users with less experience or expertise in wine reviewing. We conclude, that online platforms as well as potential customers should be aware of the phenomenon of reputation inflation and simplifying feedback to one number might do a disservice to review platforms’ goal of providing a representative quality assessment.
