Additionally, recent literature reports that online ratings in peer-to-peer markets tend to be inflated overall, undermining the reliability of online ratings as a quality signal. This study proposes a two-period model for optimal price setting that takes (potentially inflated) ratings into account. Our theoretical findings suggest that sellers in the medium-quality segment have an incentive to lower first-period prices to monetize on increased second-period ratings and that the possibility on monetizing on second-period ratings depends on the reliability of the rating system. Additionally, we find that total profits and prices increase with online ratings and additional quality signals. Empirically, conducting Difference-in-Difference regressions on a comprehensive panel data set from Airbnb, we can validate that price increases lead to lower ratings, and we find empirical support for the prediction that additional quality signals increase prices. Our work comes with substantial implications for sellers in peer-to-peer markets looking for an optimal price setting strategy. Moreover, we argue that our theoretical finding on the weights between online ratings and additional quality signals translates to conventional online markets."}],"citation":{"apa":"Neumann, J., &#38; Gutt, D.

We use data from a popular German Question & Answer community where goals are represented in the form of badges. In particular, our analysis of this data hinges on the fact, that in this Question & Answer community, badges in a hierarchical badge system are in-creasingly challenging to attain up to a certain badge. After this certain badge, the difficulty level sud-denly drops and remains constant throughout up to the last badge in the hierarchy. Our findings indi-cate that after successful badge achievement users increase their subsequent effort to attain the next badge, but only as long as badges represent a challenge to the user.

(1999) propose a prospect theory model for goal behavior. Their analytical model is based on the assumption that goals inherit the main properties of the prospect theory value function, i.e., reference point dependence, loss aversion, and diminishing sensitivity. We investigate whether these main properties transfer to goal behavior in the field. We take user activity data from a gamified Question & Answer community and analyze how users adjust their contribution behavior in the days surrounding goal achievement, where goals are represented by badges. We find that users gradually increase their performance in the days prior to earning a badge, with performance peaking on the day of the promotion. In subsequent days, user performance gradually diminishes again, with the decline being strongest on the day immediately following the badge achievement. These findings reflect the characteristic S-shape of the prospect theory value function which is convex below the reference point and concave above it. Employing the target-based approach, we can interpret the value function as a cumulative density function of a unimodal probability distribution. Our results suggest that it is more likely that active members of the community focus on the next badge relative to the status already achieved, as their next goal and are less likely to focus on more remote (higher-ranked) badges. Our results thus support the transferability of the main properties of the prospect theory value function to goal behavior in the field and suggest a distinct shape of the value function around goals."}],"language":[{"iso":"eng"}],"doi":"10.1287/deca.2016.0331","author":[{"full_name":"von Rechenberg, Tobias","last_name":"von Rechenberg","first_name":"Tobias"},{"full_name":"Gutt, Dominik","first_name":"Dominik","last_name":"Gutt","id":"14368"},{"id":"21117","full_name":"Kundisch, Dennis","last_name":"Kundisch","first_name":"Dennis"}],"year":"2016","title":"Goals as Reference Points: Empirical Evidence from a Virtual Reward System","date_updated":"2022-01-06T06:54:02Z","publication_status":"published","citation":{"mla":"von Rechenberg, Tobias, et al. “Goals as Reference Points: Empirical Evidence from a Virtual Reward System.” <i>Decision Analysis</i>, no. 2, INFORMS, 2016, pp. 153--171, doi:<a href=\"https://doi.org/10.1287/deca.2016.0331\">10.1287/deca.2016.0331</a>.","ama":"von Rechenberg T, Gutt D, Kundisch D.

This study empirically investigates the relationship between quality and price, commonly captured by the Value dimension in multidimensional rating systems, to reveal whether reviewers form a perception of quality that they then express in the Value dimension, rather than in the Overall rating. We test our hypotheses on a comprehensive panel dataset for 14,859 Airbnb listings in New York. Our preliminary empirical findings show that an increase in price leads to a significant and substantial decrease in the Value rating, suggesting that Value ratings can offer a valuable source of information for potential buyers in addition to the supposedly inflated Overall rating. Moreover, this mechanism has substantial implications for potential buyers who seek to evaluate a listing’s quality and for a seller’s price setting.

We use data for over 14,000 offerings from Airbnb which we collected for New York City. Our findings indicate that hosts whose offerings achieve star rating visibility significantly increase their prices by an average of 2.69 € more than hosts with comparable offerings who do not experience this rating visibility during the time of observation. Out of all offerings who achieve rating visibility, we identify the upper quartile of hosts to be the main driver of this price increase, whereas the first 75% percent show only a marginal price reaction. These results can serve as a first step towards understanding the motivation of people to provide assets to the sharing economy."}],"date_created":"2017-10-17T12:41:41Z","file":[{"file_name":"254-RIP_ECIS2015-Sharing_means_caring_2594_final.pdf","file_size":707962,"access_level":"closed","relation":"main_file","date_updated":"2018-03-21T09:43:15Z","file_id":"1486","success":1,"content_type":"application/pdf","creator":"florida","date_created":"2018-03-21T09:43:15Z"}],"department":[{"_id":"276"}],"type":"conference"}]
