摘要
Event studies are often estimated with Zellner's seemingly unrelated regressions (SUR) estimator and hypothesis tests are applied to cross equation combinations of the coefficients corresponding to event dummy variables. A number of recent event studies fail to point out a useful computational simplification for obtaining the necessary covariance matrix and test statistics. © 1990.
