WRDS is a web based platform which provides comprehensive financial, accounting, economics, management, marketing, banking and insurance data from various economic data banks. WRDS is operated by the Wharton School of the University of Pennsylvania (http://www.wharton.upenn.edu/) in the United States. WRDS is characterized by the fact that data from different integrated databases can be searched, uniformly selected, and finally stored in a unified file format (Excel, Stata, SAS, etc.).
WRDS is considered the de facto standard in quantitative empirical capital market research. With access to this source, high-quality teaching and research are possible.
