This study clarifies the model that should be applied when investigating the impact of an event on outcome variable for a perfectly-matched sample. Empirically, DiD regression is a widely used approach in analyzing exogenous shocks with imperfectly matched or unmatched sample. Results from the coefficient and graphic analyses show that only dummies that indicate the post-treatment effect shall be considered if exact matching in individual characteristics is conducted beforehand. The results can provide clear guidance for social science studies such as finance and economics
