(Press-News.org) High testosterone levels in CEOs negotiating mergers and acquisitions are linked to a higher rate of dropped deals and an increase in hostile takeover attempts, according to a new study in the current issue of Management Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS®).
"Deal or No Deal: Hormones and the Mergers and Acquisitions Game" is by Maurice Levi, Kai Li, and Feng Zhang of the Sauder School of Business at the University of British Columbia. The study appears in the current issue of Management Science.
A podcast interview with Prof. Levi is at www.scienceofbetter.org/podcast/levi.html.
Although observers might expect M&A bids to follow analysis of business advantage, the authors find that more human factors are also at work.
"We find a strong association between male CEOs being young and their withdrawal rate of initiated M&As," the authors say, characterizing these rejectionist younger executives as showing dominance-seeking behavior. "High testosterone responders tend to reject low offers even though this is against their interest."
Younger CEOs are 4% more likely to initiate an attempt to acquire another company than older men, the study finds. In a more marked finding, male CEOs' relative youth increases their likelihood of withdrawing a merger/acquisition bid by as much as 20%.
The authors also find that when companies being approached about a merger or acquisition have younger CEOs, there is a greater likelihood – by 2% - of a tender offer. Tender offers are used by bidding companies to bypass targeted companies' leadership and directly contact stockholders to purchase controlling shares.
In the study, the main effect of high testosterone was upon CEOs on the bidding side of negotiations to acquire another company, not the CEOs of the target company. Nevertheless, target CEOs' testosterone levels featured prominently when their refusal to continue negotiations led to a hostile takeover attempt.
The study builds upon a 2007 experiment conducted among students by Terence C. Burnham of Harvard University. In the two-player game, each team must agree how to divide a sum of "free" money or lose the entire sum. In this "ultimatum" game, high-testosterone men were more likely to reject what they perceived as low offers.
In the Burnham experiment, saliva from participants' mouths was swabbed to measure testosterone levels. In the current paper, age is used as a proxy for testosterone.
The current authors use data from Thomson's SDC database for more than 350 acquisition bids during the ten-year period from 1997-2007 to test the behavior of 'bidder' male CEOs. The average age of bidding firm males was 56 years old. The authors categorized CEO's under age 45 as young for the purposes of this study.

Elimination of a molecular gatekeeper leads to the development of arthritis in mice, scientists report in a study published in the Journal of Experimental Medicine. The newly discovered gatekeeper is a protein that determines the fate – survival or death – of damaging cells that mistakenly attack the body's own tissues and lead to autoimmune disorders such as arthritis.
Better understanding how arthritis develops will offer scientists an opportunity to explore new types of treatments for patients whose arthritis has not been effectively treated with current therapies.

JUPITER, FL, September 8, 2010 – A team led by a Scripps Research Institute scientist has for the first time identified a new gene that is required for memory formation in Drosophila, the common fruit fly. The gene may have similar functions in humans, shedding light on neurological disorders such as Alzheimer's disease or human learning disabilities.
The study was published in the September 9, 2010 edition (Vol. 67, No. 5) of the journal Neuron.
"This is the first time we have a new memory and learning gene that lies outside what has been considered the most fundamental ...
COLUMBUS, Ohio – The wasting disease associated with some cancers that is typically seen affecting skeletal muscles can also cause significant damage to the heart, new research in mice suggests.
Before now, cachexia, characterized by muscle wasting and dramatic weight loss, was believed to spare the heart. But an Ohio State University study showed that the condition reduces heart function and changes the heart muscle structure in mice with colon cancer.
Previous studies have suggested that cachexia is responsible for between one-fifth and one-third of all cancer deaths. ...
COLUMBUS, Ohio – Almost three out of four cats in a new study wore collars consistently during a six-month study, suggesting that most cats will tolerate a collar even if their owners are skeptical about its success.
In fact, in almost 60 percent of cases, the animals' tolerance of collars exceeded owners' expectations that their cat would keep the collar on without much trouble.
The researchers suggest that, armed with this data, veterinarians should include a discussion about the importance of identification during annual wellness exams of pet cats. They also say ...
Two opportunistic pathogens that were once thought to be very different have evolved some sexual reproduction and disease-causing habits that are not only similar but also suggest that in the microbial world sex and virulence are closely linked, according to a review published this week in the online journal mBio™.
"Although the mechanisms used by bacterial and fungal species to promote genetic exchange are distinct, recent studies have uncovered surprising parallels between pheromone signaling in these species," says Richard Bennett of Brown University who co-authored ...
Obesity and infertility frequently go hand in hand. Now, researchers reporting on studies of mice in the September issue of Cell Metabolism, a Cell Press publication, might have figured out why that is, and the results come as something of a surprise.
"There was a sense that the reproductive dysfunction was due to insulin resistance," said Andrew Wolfe of Hopkins Children's. "What we propose is a fundamentally new model showing that different tissues respond to obesity differently and that while cells in the liver and muscle become insulin resistant, cells in the pituitary ...
New findings reported in the September issue of Cell Metabolism, a Cell Press publication, appear to explain why people who carry specific and common versions of a single gene are more likely to have high cholesterol and to suffer a heart attack. Studies in mice show that the gene, known as sortilin (SORT1), controls the release of LDL (a.k.a. "bad") cholesterol from the liver into the bloodstream.
The findings suggest that SORT1 may be a good target for new cholesterol-lowering drugs, according to the researchers.
"The vast majority – some 95 percent -- of cardiovascular ...
In children with wrist fractures, a splint is as effective as a cast and provides greater comfort and easier hygiene, found a study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100119.pdf.
Distal radius fractures — wrist fractures — are the most common break in children and a frequent reason for emergency department visits. The usual treatment is a short arm cast for four to six weeks with follow up visits to an orthopaedic surgeon.
The study, a randomized controlled trial with 92 children aged 5 to ...
Researchers at the Buck Institute for Age Research have discovered a novel way in which insulin affects cell metabolism and cell survival. Surprisingly the insulin signaling pathway, which is involved in aging, diabetes and stress response, is active at a deeper level of cell activity than scientists expected. The study appears in the September 8th issue of Cell Metabolism.
Insulin is vitally involved in many cell functions. Buck Institute faculty and lead author Gordon Lithgow, PhD, says scientists have known for years that insulin is involved at the level of cell activity ...
Alcohol abuse and dependence are often associated with a high body mass index (BMI).
A new study shows that alcohol-related brain injury may result from a complicated fusion of hazardous drinking, chronic cigarette smoking, and even elevated BMI.
Prior research has shown that alcohol abuse and dependence are typically associated with higher rates of obesity, as evidenced by a high body mass index (BMI). Findings from a new study of the relationship between BMI and regional measures of brain structure, metabolite concentrations, and cerebral blood flow suggest that ...
