Recent high profile data breaches have once again attracted the public’s attention. Though studies have investigated various aspects of data breach issues, breached firms’ responses to the public are still under investigated. In this study, we explore the nature of response strategies and how different types of responses may influence the market values of breached firms. Using a sample of data breaches from 2005 to 2018, this study provides managerial implications on the response strategies in order to mitigate the negative impact after data breaches.
