Foghorn.Data.Crsp.CcmLookup

Description

This module defines the variable set for the CRSP/Compustat Merged (CCM) Link Table, represented as a GADT (CcmLookupV). Each constructor corresponds to a named link-table variable and is indexed by an EconType (e.g., Int_, Text_, Date_).

Synopsis

data CcmLookupV (i :: EconIndices) (a :: EconType) where
- Gvkey :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Linkdt :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Date_
- Linkenddt :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Date_
- Lpermco :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Lpermno :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Cik :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Text_
- Conm :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Text_
- Cusip :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Text_
- Gind :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Gsubind :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Naics :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Sic4 :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Sic4_
- Tic :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Text_
- Year1 :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
- Year2 :: CcmLookupV ('Panel 'Gvkey_ 'Datadate_) 'Int_
