For love and money June 16, 2004 - 9:49AM Quotes from: http://www.smh.com.au/articles/2004/06/16/1087244950274.html?oneclick=true For the first time, researchers have conducted a study that measures the value of sex in dollars and cents. According to the findings, couples who engage in sex at least four times a month bring themselves a measure of happiness equal to $71,500 a year compared with couples who have sex only once a month. The measure was derived through a complicated calculation that converted so-called units of happiness into dollars. The result supported a central finding of the research: Nothing makes adults - regardless of gender or age - as happy as sex. The two authors - David Blanchflower of Dartmouth College in Hanover, New Hampshire, and Andrew Oswald of Warwick University in Britain - used statistical analysis to evaluate data from a group of 16,000 adult Americans surveyed from 1988 to 2002. Their paper, titled "Money, Sex and Happiness", was published last month by the National Bureau of Economic Research. The researchers admitted that the bureau, known for determining recessions and US business cycles, is an unusual place for the study of sex, but they are engaged in an emerging branch of economics aimed at determining what makes people happy.
