> The obvious objective criteria is past performance

Considering that this criteria has been debunked for prices of public companies, I'd be amazed if it were true for private companies.

I'm gonna take a flying guess that the correlation studies have not been done like they have for public, due to the opaqueness of private pricing.

The studies have been done, and there is a much stronger correlation between past performance and future performance in private equity than in the public markets. In the public markets for active fund managers, there is almost no correlation. For vc funds, there is a decent correlation. My hypothesis is that the reason for the difference is information inefficiency. In the public markets, everyone is oerating with the same information, so it's hard to create a sustained advantage. In the private markets, one fund may have access to information (seeing companies no one else sees, knowing customer or acquirers, etc). Success often begets success because funds with successes get positive press which leads more entrepreneurs to go to them.

Very interesting. Link?

BTW: Were the prices self-reported?

I can't find links to the papers themselves, but the research was published by Lerner and Stahlman at HBS. They looked at firms that had top quartile venture funds and then looked to see what percentage of them remained in the top quartile in the subsequent fund. For public market managers, the measure was the same but on a year over year basis rather than fund over fund.
