Gamification and incentives Is there any (theoretical?) work on &quot;gamification&quot; in game theory?
I do not have a proper definition of gamification, but StackExchange would be an example. Contributers like us provide a costly service without monetary compensation, but in exchange for fictional reputation points or badges that do not mean much -- other than it being fun to obtain them. I certainly would not post anything without the &quot;game aspect&quot; implying a certain non-monetary payoff that can be designed.
Moreover, it is different than other non-monetary services like organizing workshops or refereeing, which at least have real-life consequences for my professional reputation.
It seems that there is already some prior work on theory of gamification from game theory perspective. For example, Easley &amp; Ghosh (2016), provide theory on optimal badge design even explicitly mentioning sites like StackOverflow and their paper seems to be highly cited.  Hamari, Huotari &amp; Tolvanen (2015) have article titled &quot;Gamification and economics&quot; which offers a survey of uses of gamification in various economic concepts. The paper itself does not seem to offer any novel models but it offers a literature review with a chapter specifically focusing on game theory.
