Event studies and CRSP

Posted in Wharton


Many people who do research are interested in finding out how the trade in stocks of a listed company are affected by certain events. These events can for instance be announcements of company results or news surrounding mergers / acquisitions, etc. Datastream has a specific tool to do this type of research called a Request table.


Doing regular searches in Center for Research in Security Prices (CRSP) in WRDS you can only do a single search for information using one specific date range for 1 or more companies. CRSP, however, has a tool to do event studies which is available under tools in Wharton: see this option on the left side in the menu.



After clicking the Tools option you can find the "events" tool called "CRSP - Daily Extract with Time Window (Annual Updates)". 



Using the tool you can download four types of data surroubnding dates for companies:

  • Information on trading dates
  • Identification information
  • Price information
  • Share information
