Ovulation affects women's financial decisions

Posted on Feb 27 2014 | IANS

New York, Feb 27 : If it puzzles you why your wife becomes more demanding sometimes, the answer lies in the biological changes in her body every month, says research.

Women's behaviour changes during ovulation and research indicates that even their financial decisions are altered a great deal for at least a week every month.

The ovulatory cycle alters women's behaviour by subconsciously motivating them to outdo other women, according to research from The University of Texas at San Antonio (UTSA) and the University of Minnesota Carlson School of Management.

The researchers conducted studies, one of which had ovulating and non-ovulating women play the "dictator game".

In this popular economic experiment, a person is given a fixed amount of money that she can choose to share with another person.

"We found that ovulating women were much less willing to share when the other person was another woman. They became meaner to other women," said lead author of the study Kristina Durante.

Whereas non-ovulating women shared about 50 percent of the money with another woman, ovulating women shared only half as much, keeping the rest of the cash for themselves.

This research could have important implications for marketers, consumers and researchers.

In another study, women made product choices that could either maximise their individual gains or maximise their relative gains compared to other women.

For example, women indicated if they preferred to have a USD 25,000 car while other women got USD 40,000 cars (Option A) or have a USD 20,000 car while other women got USD 12,000 cars (Option B).

The study found that ovulating women preferred Option B, choosing products that would give them higher standing compared to other women.

"What's interesting about this finding is that ovulating women are so concerned about their relative position that they are willing to take less for themselves just so that they could outdo other women," said study co-author Vladas Griskevicius.

The study was published in the Journal of Marketing Research.
