After men in Spain got paternity leave, they wanted fewer kids (Quartz)

From the article:

“There are a couple of reasons that I’d be hesitant to believe that these same impacts would apply elsewhere,” said David Evans, an economist at the Center for Global Development. “In Spain, almost no men were taking paternity leave before the policy, and that jumped to more than half of men after the reform. At the same time, men in Spain wanted more children than women did. That wasn’t the case in a number of other European countries.”
