WRDS Research Databases

Wharton Research Data Services (WRDS) at the University of Pennsylvania provides access to several databases. Faculty and PhD students may request an account, which allows them to store results on WRDS servers. All other students may access the data directly, but must store query results locally. 

The data vendor names (such as CBOE Indexes) are linked to the web query pages within WRDS. Listed below are only those datasets for which the University at Buffalo has a subscription. There are many datasets that we do not have access to query. If you get an error message, check to be sure UB has permission for that data.
