(Press-News.org) From Enron in the United States to Satyam in India, there are plenty of examples of corporate managers lying about their companies' earnings and ultimately hurting themselves and the businesses they work for.
Why do they do it?
A limited capacity to see the whole picture – known as "bounded rationality" -- combined with a faulty ethical compass are two big reasons, shows a new study from the University of Toronto's Rotman School of Management. The study also finds that shareholders are just as guilty of the same weaknesses and that insider trading is linked to earnings manipulation.
"For a long time we've asked ourselves, 'How come smart, rational people carry out short-term schemes that in the long-term undoubtedly are going to sink them?'" says author Ramy Elitzur, who holds the Edward J. Kernaghan Professorship in Financial Analysis and is an associate professor of accounting.
"The answer is - we're not rational. We're rational only in a limited sense."
The study bases its findings on a model of the manager-owner relationship over time. The model is also noteworthy for combining principles of game theory – used to predict strategic behaviour -- with the idea of bounded rationality – that our decisions are always made within the limits of available time, information, and the human capacity to analyze it.
"It tells us, for example, that if we would like to have managers who engage less in earnings manipulation and in insider trading, we should look for managers who are more ethical and suffer less from bounded rationality," says Prof. Elitzur.
That's not a trivial finding, he says, because the model also shows that choosing less ethical managers may be in the best interests of current shareholders, but not future ones. Unless current shareholders also suffer a penalty for such a choice, they will encourage unethical and damaging behaviour. Some provisions in the U.S. Senate's Financial Regulation Overhaul bill from 2010 help to guard against these tendencies, the study says.
The case of Enron is well-known. The scandal at Satyam Computer Services was dubbed "India's Enron," and broke in 2009. Prior to his resignation, Satyam's chairman Ramalinga Raju admitted to years of systematic inflation of earnings and assets, beginning with small manipulations of account statements that eventually got out of control.
Prof. Elitzur says that it took a decade to develop his model and get it published partly because of initial resistance to his findings.
"Many accountants believed that markets are efficient and as such, a lot of the issues of earnings management would be corrected by the markets," he says. "But this belief has changed over time, and we understand better now that earnings manipulation occurs and does indeed affect markets."

CHICAGO (November 14, 2011) – According to the results of a new study published in the November 2011 Journal of the American College of Surgeons, malpractice lawsuits against U.S. surgeons occur often and can take a profound personal toll on the surgeon, resulting in emotional exhaustion, stress, and professional dissatisfaction.
The researchers examined personal and professional characteristics and found malpractice lawsuits were strongly and independently linked to surgeon depression and career burnout. The stress caused by malpractice litigation was rated as equivalent ...
Imagine a cellphone battery that stayed charged for more than a week and recharged in just 15 minutes. That dream battery could be closer to reality thanks to Northwestern University research.
A team of engineers has created an electrode for lithium-ion batteries -- rechargeable batteries such as those found in cellphones and iPods -- that allows the batteries to hold a charge up to 10 times greater than current technology. Batteries with the new electrode also can charge 10 times faster than current batteries.
The researchers combined two chemical engineering approaches ...
Orlando –A new study from researchers at the Perelman School of Medicine at the University of Pennsylvania and collaborators at various institutions, presented at the 2011 American Heart Association Scientific Sessions, shows that a novel, non-invasive measurement of arterial wave reflections may be able to predict who is most at risk for heart failure. The authors presented data from an ancillary study of the Multi-Ethnic Study of Atherosclerosis (MESA).
When the heart contracts it generates a pulse or energy wave that travels through the arteries. This wave gets reflected ...
BINGHAMTON, NY -- Online retailers have long wondered if trumpeting consumer-behavior statistics on their websites could hurt business. New findings from Binghamton University should ease their fears, just in time for Cyber Monday.
Qi Wang, an associate professor of marketing at Binghamton University, studied the effects of user comments and sales statistics that accompany products offered on e-commerce sites. While the impact of positive and negative feedback has been well understood, much less was known about so-called "observational behavior" - aka a person's tendency ...
Researchers at the Medical College of Wisconsin have found a possible link between norovirus, a virus that causes "stomach flu" in humans, and food allergies. The findings are published in The Open Immunology Journal, Volume 4, 2011.
Mitchell H. Grayson, M.D., associate professor of pediatrics, medicine, microbiology and molecular genetics at the Medical College, and a pediatric allergist practicing at Children's Hospital of Wisconsin, is the corresponding author of the paper.
The researchers took mice infected with norovirus and fed them egg protein. They then examined ...

Researchers and conservationists from the Wildlife Conservation Society's Guatemala Program, WCS's Bronx Zoo, the National Park Service of Guatemala, and other groups report a major conservation victory from Central America: a bumper crop of magnificent scarlet macaw fledglings that have now taken flight over the forests of Guatemala.
The newly fledged birds total 29 macaws, a big success for conservationists working in the Maya Biosphere Reserve who were hoping to record at least one fledgling from each monitored nest (24 nests in total) during the 2011 season. The monitoring ...

Hospitals that do not have cardiac surgery capability can perform nonemergency angioplasty and stent implantation as safely as hospitals that do offer cardiac surgery. That is the finding of the nation's first large, randomized study to assess whether patients do just as well having nonemergency angioplasty performed at smaller, community hospitals that do not offer cardiac surgery.
Results of the study, called the Cardiovascular Patient Outcomes Research Team Elective Angioplasty Study (C-PORT-E), are being presented on Nov. 14, at the American Heart Association's Scientific ...
