Abstract

Classical Manski bounds identify average treatment effects under minimal assumptions but, in finite samples, assume that latent conditional expectations are bounded by the sample's own extrema or that the population extrema are known a priori -- often untrue in firm-level data with heavy tails. We develop a finite-sample, concentration-driven band (concATE) that replaces that assumption with a Dvoretzky--Kiefer--Wolfowitz tail bound, combines it with delta-method variance, and allocates size via Bonferroni. The band extends to a group-sequential design that controls the family-wise error when the first ``significant'' diversity threshold is data-chosen. Applied to 945 listed firms (2015 Q2--2022 Q1), concATE shows that senior-level gender diversity raises Tobin's Q once representation exceeds approximately 30\% in growth sectors and approximately 65\% in cyclical sectors.
