Description
I compare the effect of anonymous social network ratings (Yelp.com) and peer group recommendations on restaurant demand. I conduct a two-stage choice experiment in which restaurant visits in the first stage are informed by online social network reviews from Yelp.com, and visits in the second stage by peer network reviews. I find that anonymous reviewers have a stronger effect on restaurant preference than peers. I also compare the power of negative reviews with that of positive reviews. I found that negative reviews are more powerful compared to the positive reviews on restaurant preference. More generally, I find that in an environment of high attribute uncertainty, information gained from anonymous experts through social media is likely to be more influential than information obtained from peers.

Description
Food safety incidents have constantly hit society and threatened human health. Hundreds of millions of people become sick after eating contaminated food every year. As the problem continues to emerge, consumers must take action to avoid purchasing risky food products. As one of the solutions, food traceability systems have been developed rapidly in many countries in recent years. More food products can now be provided with traceability information to assist consumers in making purchase decisions. To design services for grocery shoppers to access food information from food traceability systems possibly through modern technologies, this transdisciplinary user research study investigated shopper insights into food traceability information on produce provided at grocery stores, with a fusion of ideas from the disciplines of design and consumer behaviors. Through literature reviews, an online survey study, and an online interview study, this research revealed a series of shopper insights concerning (1) shoppers’ knowledge about food traceability information, (2) shoppers’ behaviors and motivations for using traceability information on produce, (3) shoppers’ perceptions towards providing traceability information on produce to them at grocery stores, (4) shoppers’ perceived important traceability information on produce, (5) shoppers’ behavior intentions of using specific ways to access traceability information on produce, and (6) shoppers’ thresholds to pay for traceability information on produce. Based on the results, this study identified design opportunities for the features, components, and mediums of the service design of future food traceability systems.
