Things have changed since the 1970s, especially for women. But a new study published this week in the National Bureau of Economic Research indicates that those changes may not be making women more content.

With all the gains that women have made in the past three and a half decades, why is happiness on the decline? The Takeaway talks to the co-authors of the paper, “The Paradox of Declining Female Happiness", Justin Wolfers and Betsey Stevenson. Both are assistant professors in public policy at the University of Pennsylvania’s Wharton School of Business.
