But do Universities also stand to loose from alumni?
Slate makes a case (however ever obliquely — I’m reading between the lines here) for stable, child-filled families:
Alumni with kids are 13 percentage points more likely than alumni without kids to give in any year. The tendency to give rises slowly—by three more percentage points total—through kids' early teens. At about age 14, as mom and dad see their kid's algebra and composition grades, they decide whether he or she will apply to the alma mater. If they decide against, then they need not give extra to grease his way in. But if the kid is legacy material, then the parents might feel a need to show some generosity to Anon U.
I didn’t say this was exact. But it’s a pretty, um, straight line from alumni with families (stability, kids!) are more generous donors. And yet too often, Universities (I’m looking at you dear old U.Va.), sit on the sidelines in this debate.
