“Competition is very important when people seek resources, political positioning, college admissions and jobs.” How well play determines its success. Perhaps everything depends on the choices that each makes. In our study, we had hoped that risk-taking weaken with age. “See that it rises up to 50 years was surprising,” says the Economist William Harbaugh, the University of Oregon (United States).

Harbaugh and Ulrich Mayr, another Economist in charge of the study, analysed how changes the risk-taking over the years, and published their findings in the journal Psychology and Aging.

Experts recruited 800 people from 25 to 75 years of age. Each volunteer had two options: solve a simple math problem and gain a bit of silver or face an opponent in competition with the possibility of obtaining a more sizeable reward.

Harbaugh and Mayr noted that men and women were more likely to face the challenge of competing for a bigger prize to aging. This trend was strongest in men, but gender predisposition to risk-taking grew to the age of 50 years and then began to descend.

Mayr emphasized his study contradicts the general idea that achievements are still important for people as the years pass. And Harbaugh stressed the importance of seeking rewards in today’s world, because this behaviour is essential in areas such as business or start-ups commercial.
