Using WRDS to connect Sustainalytics data with IBES earnings estimates data
About the Linking Methods
There are two methods for linking Sustainalytics data with IBES earnings estimates data:
- One method is to match the IBES data with Compustat data. Begin by matching CRSP with Compustat via the CCM (CRSP-Compustat Merge Database) product. Then, after adding GVKEY to CRSP data, link to Sustainalytic’s companies by using the procedure described in the Linking Sustainalytics with Compustat documentation.
- Another option is to take advantage of Sustainalytics’
REFERENCE_DATAthat contains the Sustainalytics CUSIP, and Ticker. With this method, a direct match between Sustainalytics and IBES data can be accomplished, because the IBES files contain both CUSIP and Ticker.
