Replication Data for: Designing Quality Certificates: Insights from eBay

The paper uses proprietary data from eBay, and we would like to request exemption from the data availability policy. The paper is part of an existing and ongoing data-sharing relationship between eBay and I. My coauthors and I do not receive financial compensation from eBay. All eBay related data are not collected directly by us but are being archived via eBay regular business operations. The data include de-identified information about the activity on the site of individual eBay users. All raw data are proprietary and belong to eBay, so we will not be able to share raw data with researchers that are not cleared by eBay.

Despite this restricted access, we will make all estimation programs associated with this research publicly available, and we are committed to help interested researchers replicate our results and check their robustness (e.g., by obtaining program files from interested researchers, running the programs on eBay servers, and reporting back the results). We have been and will continue to work with eBay to allow access to the data (in a manner similar to my access) to other researchers (and once researchers obtain access, we would be able to share with them our data as well).
