<p>Well, in 2008 Yale’s yield went up slightly, and Harvard’s (pre-wait-list) actually went down a skootch. So it seems unlikely that Yale lost a much greater percentage of its EA admitees than in the past. Not impossible, but unlikely, given that it actually reduced the number of RD admissions vs. prior years.</p>
<p>Yale lost EA admittees to Harvard in the past, even when Harvard had EA, too. I know some such.</p>
