The lawsuit ended with consent decrees limiting the ability of airlines to communicate surreptitiously through the shared fare database. This paper measures the effects of the litigation and its settlement on industry performance, comparing changes in outcomes between market segments that were more and less likely to be affected by the ATP case.
