January 2013

The assistant director of Georgetown Economics Services, Robert Fenili, authored the Business Economics article, "Using Event Studies to Assess the Impact of Unexpected Events." The article discusses how event studies, the quantitative assessment of the financial impact of unexpected events, can be used by CEOs, boards, and public policymakers to inform and improve their decision making. It includes illustrative event studies for two Steve Jobs-related announcements concerning his health in order to demonstrate both the potential and limitations of the technique.
