Riverripper, what does Columbia's purported "yield control" have to do with selectivity, i.e. the number of applicants admitted?
Are you serious? It definitely directly impacts the number admitted. Its a direct relationship, if they know that 80% of the people they select have to get in they only have to admit 125 people to get 100 to show up. While if they didnt do yield control and have 60% yield which is probably about what GSB has had in the recent years...they would have to admit 167 people to get the same 100 people. So in this case if both schools had 500 applicants, Columbia would admit 25% of applicants and Chicago would admit a over 33%.
How do they control their yield? Imagine a school gets 100 appliants each slightly more qualified for the last. Each school wants 10 students from this pool for their class.
-HBS admits the top 11 (90 to 100) or so of people, since they know 95% will show up.
-Chicago admits the top 17 (84 to 100) people knowing about 60% will show up so they admit more accounting for the 40% who get into and choose to attend H/S/W and other top schools.
-Columbia admits 14 students but do so by admitting #79 to #92. They know that the top handful of students will likely also get in to H/S/W and at least 95% would choose to attend those schools so they dont admit them. This ensures they have a higher yield than Chicago who admitted those students and also lowers the number of people they have to admit to attend.
I am not knocking Columbia for doing it, its their choice on how to fill their slots but it definitely does change their numbers.
