Not exactly what you're asking for but the iCrossing Search Synergy Report: Natural & Paid Search Symbiosis was an interesting read for me and seems relevent to this thread.

For this report we asked, “Does running a natural search campaign and a paid search campaign together create more value than running them in a non-integrated manner?”

Think I found it via this site at some point a while ago... ht tp://www.icrossing.com/research/. It's the third one in the list.
