This paper uses the imputation method to generate a counterfactual estimate, based on untreated observations: the average treatment effect on the treated (ATT) equals the difference between actual and counterfactual estimates. The analysis shows that there were significant anticipation effects associated with new stadiums, up to three seasons before opening.
