The Fiscal Fingerprints of Corporate Collusion

Firms that engage in bad deeds leave all sorts of clues tied to accounting and governance.

Title: Smokescreen: How Managers Behave When They Have Something to Hide (free)

How do firms that are breaking the rules try to cover up their tracks? According to a recent study, companies that are systematically involved in price fixing employ a variety of accounting and governance practices designed to throw off regulators and avoid liability. For top executives and directors at these firms who are not part of the scheme, knowing which machinations to look for could prove vital in heading off costly corporate missteps. Shareholders and analysts could benefit as well.

The authors analyzed more than 200 U.S.-based firms listed in the Private International Cartel database, which includes all cartels discovered, disclosed, and broken up by regulators from 1986 through 2010. A cartel is defined as a group of independent companies that attempt to increase their joint profits via explicit illegal agreements, such as pacts that control prices and restrict supply, usually at the direction of middle or top managers.

The database shows a rise in the number of cases in recent years, and the authors note that a 2007 study estimated that only 10 to 30 percent of cartels are uncovered. But when companies are caught, the same study found, they face stiff financial penalties, from civil litigation and the government.

Combining several sources of data—including those covering firms’ audit activity, director characteristics, financial restatements, and stock returns—the authors studied the cartel-related behavior of 216 companies, 67 of which participated in more than one price-fixing scheme. The average cartel lasted for six years before regulators stepped in, and the longest stretched out 22 years. One oil company was embroiled in 13 schemes, the most of any firm in the study.

The authors constructed a control sample of similar companies matched to each cartel firm, based on their size, SIC industry code, and other factors. In all, more than 3,500 control companies were matched to the 216 offending firms. In each stage of analysis, the authors controlled for such variables as profitability, board structure and independence, and industry trends.

On a basic level, the authors’ analysis showed, cartel firms thrived from their conspiracies: During the period of collusion, their sales grew 4.6 percent faster and their market capitalization rose 3.6 percent faster than at control firms. This payoff stood out when compared to the two-year period before the conspiracy began as well as the two-year period after it ended, when the “benefits” from the price fixing were no longer in effect. During both of those periods, the cartel and control companies grew at essentially the same rate.

But rather than passing on the profits to stockholders, colluding firms tended to plow the extra earnings back into hiring more employees and systematically expanding their property, facilities, and equipment. Because many cartel firms agree not to infringe on one another’s market share while conspiring, these forms of expansion could be diversionary in nature, the authors argue, to imply growth even though the terrain of some or all of their competitors is off limits.

Among the study’s other findings: Directors resigned or retired far more frequently at cartel firms than at their control counterparts, and when they left, the board usually shrank instead of filling their seat. “One clear possibility is that board members who become aware of wrongdoing leave quietly to evade future legal liability or to signal disagreement with management’s actions,” the authors write. And by leaving the seat vacant, the company avoids the risk of bringing a potentially effective monitor on board.
