Governance Measures
Projects --> Winner's Curse --> Data
Open the GovernanceVARS.txt
These are
- staggered boards
- limits to shareholder bylaw amendments
- limits to shareholder charter amendments
- supermajority requirements for mergers
- poison pills
- golden parachutes
To do list
Processing the SDC data:
- Find SIC codes concordance to get NAICS for old data
- Acquirer publicly traded ( must be AMEX, NASDAQ, or NYSE)
- Magic with CUSIPs : CUSIP is a nine digit number (possibly ten, ) Seven issuer, two issue, one check
CRSP processing notes:
- Estimation window 250 days ending 30 days before the Acq. must be at least 50 continuous days before the 30 days window.
- Returns and prices may contain codes. Import as var_char and reprocess?
Other notes:
- See page 9 of the paper for data processing notes.
- Data dictionary for SDC MA: http://www.edegan.com/repository/DD-ThomsonSDCMA.txt

Importing the CRSP data into the `winner' database (Amir)
Two important files: Project --> Winner's Curse --> Data --> SQL --> CRSP_NOTES Project --> Winner's Curse --> Data --> SQL --> CRSP_CODES
Data file is located in: E:\McNair\Projects\Winner's Curse\Data\CRSP-Oct10-c30cc89e52b70545-1.txt
Issue 1: The text file is 8 GB large and there's no way to open it in Textpad. I'll try to read the file in LogExpert which seems to do a neat job in in opening large files. Otherwise, I'll try to read the first few lines in the terminal. Update: I managed to open the file in LogExpert. However, extremely inefficient to scroll over the file.
I copied the file to Z:\WinnersCurse\CRSP-oct10
Entered the following command in the terminal to read the header:
head -1 CRSP-oct10.txt
CREATE TABLE CRSP ( PermNo int, date date, EXcode int, SIC int, NCUSIP varchar(10), Ticker varchar(10), Name varchar(100), NAICS int, PrimEx varchar(1), PERMCO int, CUSIP varchar(12), Price real, VOL int, RET real, ShOut int, trade int, EQRET real, VRET real );
We have unexpected data types in few columns. We'll first start by copying data into a table named CRSPtmp with varchar type for most of the fields.
CREATE TABLE CRSPtmp ( PermNo varchar(10), date date, EXcode varchar(10), SIC varchar(10), NCUSIP varchar(10), Ticker varchar(10), Name varchar(100), NAICS varchar(10), PrimEx varchar(1), PERMCO varchar(10), CUSIP varchar(12), Price varchar(15), VOL varchar(10), RET varchar(10), ShOut varchar(10), trade varchar(10), EQRET varchar(10), VRET varchar(10) ); \COPY crsptmp FROM '/bulk/WinnersCurse/CRSP-oct10.txt' WITH DELIMITER AS E'\t' HEADER NULL AS CSV -- COPY 64614281
Next, to create an index on CUSIP:
CREATE INDEX CUSIPIndex ON crspfinal(CUSIP);

We encountered an issue with the variable Purpose Code in our most recent SDC pull. Purpose Code can carry multiple values, so we had extra lines with blanks for every value other than Purpose Code. Rather than doing another SDC pull, we used the following regular expressions to solve:
Find : ^[\s}.* Replace :
Directly below is the original SDC file prior to our fix
E:\McNair\Projects\Winner's Curse\Data\SDC_MA_Oct10v4 -raw
Directly below is the SDC file post-fix
E:\McNair\Projects\Winner's Curse\Data\SDC_MA_Oct10v4
11332 rows were removed as a result of our regular expression use.
