"Incentivise"

Under the heading "my pet hates" I should have put - people who play havoc with the English language - I especially dislike those who adopt American pronounciations, make up their own pronounciations - or in the case of Tony Blair today create new words. Usually this involves making verbs from nouns. Yes he really did say, about getting people back to work "We have to incentivise them". I wonder what his incentivisation was?
