Looking for a long-term commitment this
  Valentine's Day? Then don't call your love interest more than once, don't look
  them in the eye too often, and no sexual advances on the first date.
  These and other relationship sins can lower
  your social price, giving you the image of a cheap bottle of wine, meant to be
  guzzled at a party, rather than an expensive vintage, meant to be treasured
  for a special occasion, says a U.S. professor of economics who theorizes on
  the economics of the mating game.
  According to David Anderson's study, coming
  across as "eager" or "desperate" for commitment signals a
  low social price, which drives away people looking to snag a prize husband or
  wife.
  Mr. Anderson, co-author of A Theory of
  Quality Signalling in the Marriage Market, likens the marriage game to buying
  wine.
  "People want to buy the most expensive
  wine that they can afford," he said. "If all you have to go on is
  price, you're going to assume that the higher priced wine is better."
  Mr. Anderson, an associate professor of
  economics at Centre College in Kentucky, and Shigeyuyki Hamori, an economics
  professor at Kobe University in Japan, put their theory together and tested it
  by showing student recruits a series of personal ads and asking them to which
  ones they'd be most likely to respond.
  The results showed that playing hard to get
  can often get you what you want in a relationship.
  Because it's hard to determine future
  qualities that make someone a good spouse (the study cites love, quality and
  quantity of children, prestige, esteem, health, altruism, faithfulness and the
  quality of meals as examples of household commodities that make up a
  "marital income"), an inordinate amount of weight is placed on what
  can be gleaned from early surface impressions.
  Subjects in the study found phrases such as
  "I don't spend time with just anyone" were more intriguing and
  suggested more quality than "I'm not picky" or "you won't have
  to twist my arm," which signalled desperation.
  "Marital search involves highly
  uncertain offers based on an initially meager number of signals," the
  study found. "This makes it analogous to the choice of a doctor, a
  university, or a bottle of wine under uncertainty."
  So potential suitors make their judgments
  on what the study calls a "social price" by observing the person's
  actions in phone conversations, on dates and by talking to friends and family
  of the love interest in question.
  The study even provides a handy
  mathematical formula for determining a possible mate's potential worth: *
  (social price)=f (potential contribution to marital income).
  A person can set themselves an expensive
  social price by keeping their standards high. "Be patient with sexual
  advances," Mr. Anderson said. "Don't appear desperate by staring at
  someone for a long time or calling them repeatedly. You want to appear
  accessible and available, but not too easy to attract."
  Still, surface impressions can only tell us
  so much, the study warns, and often can't fully predict who has the qualities
  that make a good spouse. In those cases of false advertising, traditional
  business models come into play.
  "Over the long run, we start to see
  most things about our spouses," he said. "And if (the person) is not
  as advertised, the same thing happens that happens in the real world -- the
  good is returned.
  "We see it frequently in the marriage
  world, where about half of all new marriages end in divorce."
  Although this economic model may seem to
  give concrete guidelines to nervous daters, not everyone in academia is quick
  to accept it as gospel.
  "For good or ill, people get married
  for all sorts of reasons," said philosophy professor David Checkland, who
  teaches a course at Ryerson University in Toronto called the Philosophy of
  Love and Sex. "This seems sort of a one-size-fits-all, as if everyone
  getting married has the same history, perceptions and preferences.
  "Any relationship theory has to
  operate on an individual level."     -    by Jordan
