Jim Alexander, former CFO of Enron Global Power and Pipeline, gives an insider account of Enron's collapse as part of Douglas Rae's Yale course Capitalism: Success, Crisis and Reform. After introducing his role at the company, Alexander walks through what went wrong: leadership that dismissed ethical concerns, accounting loopholes exploited to keep transactions opaque, and traders inflating numbers with little oversight. He describes how regulators and watchdog organizations sometimes had incentives that rewarded negligence rather than scrutiny. Alexander centers his account on the idea of the rational economic man, the assumption of self-interested rationality that he argues dominated Enron's culture and crowded out any competing notion of corporate ethics. Organized into three chapters covering introduction, background, and the causes of failure, the talk offers a firsthand, plainly delivered postmortem of one of the largest corporate frauds in American business history.
