There's a good magazine that features academics who study these questions of human cooperation and how to make it work better, called Evonomics. These are not academic journal articles but magazine type pieces written for a literate general audience. I've done a couple of Steemit pieces on stuff from there, one dealing with this issue specifically

and one more generally introducing the magazine
