I'm writing an essay and am wondering whether the following sentence is correct: "I investigate the tension between self-interest and other-regardingness."
Is other-regardingness a word? On the one hand it's in the Oxford dictionary. On the other Chrome gives me an error, and when I search Google for "define other-regardingness" the only dictionary definition that comes up is Oxford's.
(And if it exists, are there any synonyms, just in case some people aren't familiar with it?)
