Growth has been slowing around the developed world — not just in recent months but for decades. One potential reason is that women are having fewer babies. On this week's Stephanomics, reporter Jeannette Neumann visits a region in Spain with the lowest fertility rate in Europe to find out why this is happening and what it means for the global economy. Host Stephanie Flanders also talks with Darrell Bricker, co-author of the book “Empty Planet,” about his theory that the global population will begin to decline.

One way to prop up the birthrate could be to offer employees a better work-life balance. Recent U.S. data showed that people who work at home aren't just growing in number but also, on average, earn more than those who commute. Bloomberg Opinion columnist Justin Fox joins Stephanie to consider the implications of this striking fact.
