There was a lot of tooth pulling. I eventually got it in the contract but the extra incentive was so small it was hardly worth it. That said, the school picked up on the idea and it is now in its second year.
The email below is from the research office.
In 2011 Vice President Jon Fink created the "PI Incentive" program to
encourage faculty to engage in sponsored research. The program returns a
portion of the F&A earned to Principal Investigators, as long as they
earned at least $5,000 for PSU. Incentive amounts were distributed last
fiscal year based on the amounts earned in FY 2010 and FY 2011.
We are pleased to announce that RSP has funded this program for the third
consecutive year. Money was transferred to PIs individual "PIN" index
codes in November based on F&A earned last fiscal year. Please contact
your department chair for details.
