A columnist writing in response to the passage of a new law in New York legalizing same-sex marriage says the institution of marriage is evolving. The author cites research done by M.V. Lee Badgett, economics and director of the Center for Public Policy and Administration, and her book, “When Gay People Get Married.” In researching the book, Badgett found that European countries that legalized same-sex marriage during the past 15 years saw lower divorce rates and higher levels of heterosexual marriage than countries that didn’t legalize it.
