Abstract:
This paper tests the hypothesis that negative client stock returns following the revelation that Enron documents had been shredded are attributable to confounding effects as opposed to a loss of Andersen's reputation. We find that a sharp decline in oil prices along with differences in the industry composition of the Andersen and Big 4 client portfolios combine to produce significantly more negative returns for Andersen clients relative to Big 4 clients, and for Andersen's Houston office clients relative to its clients in other locations. The market reaction to two other Enron-related events also offers little support for a reputation effect.
