How do economics and game theory explain the dating scene in D.C.? To find out, join us on October 27 at 6:00 p,m. for a reception and book forum with journalist Jon Birger, author of Date-onomics: How Dating Became a Lopsided Numbers Game. Using a combination of basic economic principles, demographics, game theory, and number crunching, Jon Birger explains America’s curiously lopsided dating and marriage market among single, college-educated, looking-for-a-partner women. Birger investigates not only the consequences of this unequal ratio of college-educated men to women on dating but also a host of other social issues.
