A Simulation Investigation of Firm-Specific Equation Models as Used in Accounting Information Event Studies
Researchers studying stock price reactions to accounting information releases can choose among several statistical methods/models. We investigate the empirical distribution of common statistics used in SUR and OLS estimation via monte-carlo methods on daily stock return data. We find that the SUR statistics over reject the null hypothesis far too often and in fact the commonly used SAS F-statistic rejects the null more often than other related statistics. We give some indication of the amount of correction needed and also the corrected power statistics.
