This is the title of Marvin Olasky's interview of Jennifer Roback Morse in the June 19, 2010 issue of World.
According to Olasky's introduction to his interview, Dr. Morse is "an economist and the mother of two children plus two books: Love and Economics [subtitle Why the Laissez-Faire Family Doesn't Work] . . . and Smart Sex about, as the subtitle says, Finding Lifelong Love in a Hookup World."
Olasky's interview is well worth reading, and I would think the books as well, although I haven't read them (yet).
