The Performance Of Military Defense Contracted Companies After September 11th, 2001: The Case Of Politically Connected Companies, Derek J. Larsen

All Graduate Plan B and other Reports

This paper examines the effect that the terrorist attacks on September 11th, 2001 had on the stock prices of companies within the military defense industry. In addition, this paper studies the effect of the defense firms’ political engagement (through lobbying activities) and how this affected the stock price response to the terrorist attacks. Our study finds that the cumulative abnormal returns of these companies are positively significant and that companies who lobbied experienced higher returns relative to those who did not lobby.
