Termination of access to Survivor-Bias-Free Mutual Fund database

As of July 1 2025, students and staff of the EUR no longer have access to the Survivor-Bias-Free Mutual Fund Database via Wharton Research Data Services (WRDS).

This database provided survivorship-bias-free data on U.S. mutual funds and was a specialized subset of the broader CRSP (Center for Research in Security Prices) dataset, which Erasmus University continues to have access to. The license for this particular subset has not been renewed, and access has now ended.
