University of Pennsylvania students have the benefit of full access to the Wharton Research Data Services (WRDS) database.

Started in 1993 by the Wharton School at the University of Pennsylvania, WRDS is considered to be an essential tool for academic research, especially for students in need of business and economic data.

WRDS democratizes data access so that all disciplines can easily search for concepts across the data repository. Partnering with global vendors, WRDS hosts 350+TB of data — the broadest collection of data on the most robust computing infrastructure to give users the power to analyze complex information at speeds of up to 400MB per second.

Users can choose among various output formats including fixed-width text files (.txt), comma delimited files (.csv), Excel files (.xls), HTML tables (.HTM), SAS Windows or Solaris files (.sas7bdat), STATA files (.dta), SPSS files (.sav) and more.
