CEO Compensation and Returns to Public and Private Acquisitions: Testing the Shareholder Value Hypothesis (view source)

==To do==
We want to add:
*A unique CEO-Firm key
*IT target - and sum through
*VC backed target - and sum through
===Same Day Acquisitions===
We need to solve the multiple acquisitions on a single day problem. The result needs the variables listed for acquisitions below (crucially including pub/priv indicator, CAR5, sameday indicator, sharesoutstanding, with a cusip-year key).
**We would need to calc day number again for SDC, which would mean bringing in the dayno table.
**Then we'd need to create new estimation data for the missing records: acq_cusip, date_announced, acqkey, dayno, avg(ret) as ret, primex, vret, eqret, reldayno, retdayno (see EstimationBase) - but maybe this time take SHOUT with you!
**Build a new EventBase, and everything in CRSP_TABLE.sql through to Flatter
**Join this to EstimationOutput, calculate the abnormal returns and then CARs.
